Outdoor Lighting Final Inspection Checklist: Pass First Time with This Complete Guide

Most landscape lighting inspection failures happen not because installers don't know the code, but because they call for the wrong inspection at the wrong stage, show up without the required documentation, or don't realize that fixtures added during installation changed their approved scope. Final inspection is not just a repeat of rough-in — it is a comprehensive review of the completed system against the approved permit, with the inspector comparing what's installed against what was approved, verifying every component is operational, testing every protection device, and checking every measurement against code. This guide maps the three inspection stages, the inspector's physical walk sequence, and the 18-item pre-final checklist that prevents failures before the inspector arrives.

What Final Inspection Covers That Rough-In and Underground Don't

Underground inspection covers buried cable — depth, type, connector ratings, separation. Rough-in covers wiring methods and primary connections before concealment. Final inspection covers everything in its completed, energized, operational state: every fixture lit and aimed correctly, every protection device tested functional, all documentation present and matching, approved plan compared to as-installed condition, and — critically — any additions made during installation that weren't on the approved plan. Per the Procore final inspection guide: "Approved plans match the final construction. If they don't, the inspector can ask for the building to be altered or for a revised plan of the finished building to be submitted." This plan-vs-installation comparison is unique to the final stage and is the source of the most costly final-stage surprises.

Stage 1: Underground — Before Backfilling (Only Chance for This Stage) Stage 2: Rough-In — Before Concealment (May Combine with Underground) Stage 3: Final — Complete Installed System vs Approved Plan Permit Card + Stamped Plans Must Be On-Site for Final Added Fixtures = Scope Creep = Revised Permit Required Before Final California Title 24: Certificate of Installation Required at Commercial Final
⚡ Code Reference Notice Inspection stages, required documentation, and specific procedures vary by jurisdiction and project type. Some jurisdictions combine inspection stages; others require additional stages. Always confirm with your specific AHJ what inspections are required and in what sequence before beginning work. This guide reflects general practice for NEC-governed landscape lighting installations; commercial projects may face additional requirements under state energy codes and local amendments.

Three Inspection Stages: What Each Covers and When to Call

Calling for the wrong inspection at the wrong stage — or missing a stage entirely — is one of the most common permit management errors for landscape lighting. Each stage has a specific window when it must be called, and missing the window can require expensive re-work to create access for the inspector.

1Underground / Trench Inspection
When to call:

After cable is installed in the trench and all buried connectors are in place — but BEFORE any backfilling. This is the only opportunity to verify underground elements. Once the trench is closed, the inspector cannot verify compliance without excavation.

What the inspector checks:
  • Burial depth: probe at 10-15 foot intervals from soil surface (not mulch). Minimum 6 inches per NEC Table 300.5 Column 5
  • Cable type: must be direct-burial rated with visible marking on jacket
  • Cable separation: low-voltage cable not sharing conduit with 120V conductors
  • Connector type: buried splice connectors must be direct-burial rated (gel-filled or heat-shrink)
  • Conduit under hardscapes: Schedule 40 PVC or equivalent, proper depth and entry/exit protection
  • Warning tape: orange direct-burial warning tape 2 inches above cable is best practice in some jurisdictions
The critical rule:

Do not backfill until the underground inspection is approved. If you backfill before inspection, the inspector cannot approve what they cannot see and may require re-excavation. See the inspection failure codes guide for the buried-before-inspection problem.

2Rough-In / Intermediate Inspection
When to call:

After wiring is installed but before connections are enclosed or concealed. For landscape lighting, this typically covers the transformer mounting and primary-side electrical work. For plug-in transformer systems without a new circuit, the rough-in inspection may be combined with the underground inspection or waived entirely by some AHJs.

What the inspector checks:
  • Transformer mounting height above grade (per listing label requirements)
  • Primary circuit connection method and conductor sizing
  • GFCI protection at the supply outlet (TEST/RESET function verified)
  • While-in-use outlet cover if transformer is plugged in at this stage
  • Any conduit runs from the transformer mounting to the primary supply
  • Junction box installations if any hardwired connections are made above grade
May be combined:

For simple plug-in landscape lighting systems, many AHJs allow the underground and rough-in stages to be combined into a single site visit. Confirm with your AHJ before calling for the first inspection whether both stages can be covered in one visit or require separate scheduling.

3Final Inspection
When to call:

After all work is completely finished — every fixture installed, transformer fully operational, all covers and housing elements in place, all connections made, system energized and all zones functional. Do not call for final when partial work remains.

What the inspector checks:
  • All fixtures lit and operational during the inspection visit
  • Installed system matches the approved permit drawings
  • All required documentation is on-site (see documentation section)
  • GFCI outlet function verified by TEST/RESET procedure
  • Transformer mounted at correct height and per listing instructions
  • Pool setback measurements for any pool-adjacent fixtures
  • Load calculation confirming transformer not overloaded
  • All listing marks legible on transformer and fixtures
  • While-in-use cover at transformer outlet
  • Wire routing visible above grade (conduit) properly secured and protected
The plan comparison:

Final is the stage where the inspector compares as-installed against the approved plan. Any fixture added during installation that wasn't on the approved plan is scope creep that must be resolved before final inspection — see the scope creep section below.

✓ NYS Inspection Requirement Documentation — Representative of Most States New York State's published building permit inspection requirements list (representative of most state frameworks) includes for low-voltage systems: "building systems, including underground and rough-in (plumbing, hvac, low volt wiring, electrical systems, fire alarm, smoke alarm, burglar, etc.) [inspection required before covering]; and final inspection(s) after all work authorized by the building department has been completed." This confirms the general principle: underground before covering, final after completion — with rough-in as an intermediate stage for any primary electrical work. The Mike Holt forum confirms: "The rough inspection needs to be done before walls go up. Or possibly for other reasons where the installation will get buried and become uninspectable." For landscape lighting: the critical "before covering" moment is the underground trench before backfilling.

A final inspection checklist should do more than confirm that every fixture turns on. It should verify that the installation can be understood by someone who did not install it: where power enters, how the transformer is mounted, where the cable runs, which connectors are buried, which fixtures are wet-location suitable, and what documentation proves the work. Use the electrical inspector landscape lighting checklist as a companion review before asking for final approval.

The Inspector's Physical Walk Sequence at Final Inspection

Understanding the order in which an inspector walks a landscape lighting final inspection helps you prepare in the same sequence — so your pre-final self-inspection mirrors exactly what the inspector will do.

Per Miami-Dade County's documented inspection guidelines (representative of most AHJ inspection procedures): "Building permit on the card is the same as on the route. If this is not the first inspection, read inspection records and notes on permit card." The inspector begins with administrative verification before touching any hardware — then walks the site methodically.

Final inspections often involve more than verifying that lights turn on properly. Depending on the property type, inspectors may review emergency illumination systems, pathway visibility, backup power provisions, and safe exit-route lighting intended to function during outages. Our emergency backup lighting requirements guide explains the code concepts commonly associated with egress pathways and emergency lighting systems.

Phase 1: Administrative Verification (Before Site Walk)
1
Verify permit card is on site and matches the permit number in the scheduling system
Inspector confirms the physical permit card is posted or available on site. Checks that the permit number, address, and scope match the inspection request. If the permit card is missing, the inspection may be declined. Per Garden Grove CA: "Your approved and stamped plans and permit card must be at the construction site." Have the permit card in a weatherproof sleeve, posted visibly or immediately available to hand to the inspector when they arrive.
2
Review approved plan set — verify plans are the stamped/approved set
Inspector reviews the plan set on site. Confirms it carries the AHJ's approval stamp. For landscape lighting: the plan shows fixture locations, wire routing, transformer location, pool setback measurements, and load calculations. Any set other than the stamped-approved set is not acceptable. Per the CEC Certificate of Installation process: "Date of Permit Set used for construction" and "Date of As-built Set" are separately documented fields — the approved permit set and any as-built set are distinct documents. Have the correct approved set immediately available.
3
Check prior inspection records on permit card — verify prior stages were approved
Inspector reads the inspection record on the permit card or in the electronic system to confirm that all required prior inspections (underground, rough-in) were performed and approved. If a required prior inspection stage was not completed, the final inspection cannot proceed until that stage is completed. For landscape lighting: the underground inspection sign-off is the most critical prior stage record. Missing underground inspection means final cannot proceed regardless of how good the finished installation looks.
Phase 2: Supply Side — Transformer and Primary Connection
4
Verify transformer mounting height and position per listing label
Inspector measures from soil grade to the bottom of the transformer housing. Most landscape transformer labels require 12 inches minimum above grade. Inspector verifies the transformer is mounted per its listing and labeling instructions per NEC 110.3(B). For wall-mounted transformers: checks that mounting surface is solid structure, not a decorative element. See the transformer mounting code requirements.
5
Test GFCI outlet: press TEST (outlet loses power), press RESET (restores)
Inspector tests the GFCI outlet where the transformer plugs in. Brings a small test device (lamp, outlet tester) and plugs it in, then presses TEST. If the device doesn't lose power, the GFCI is not functioning — immediate failure. Presses RESET — device must restore. An outdoor outlet with no TEST/RESET buttons (standard duplex outlet) is a violation of NEC 210.8(A)(3). Inspector does not trust visual inspection alone — tests function. See the GFCI requirements guide.
6
Verify while-in-use outlet cover closes with transformer plug inserted
Inspector confirms the outlet cover is the "while-in-use" (bubble/in-use) type that closes even with the plug inserted, per NEC 406.9(B)(1). Attempts to close the cover with the transformer plugged in — if it doesn't close, it fails. This is a simple physical test that takes 10 seconds and catches a common oversight. Have the while-in-use cover installed before calling for final.
7
Read transformer's UL listing label — confirm legibility and correct listing designation
Inspector examines the transformer's label for UL or ETL listing mark. Must be legible — if faded, bring printed listing documentation from UL's Product iQ database. Label must show listing designation appropriate for landscape lighting. Inspector checks branch circuit protection per NEC 411.6 (20 amperes maximum) if this wasn't verified at rough-in. For load calculation: confirms total connected wattage is within transformer rating.
Phase 3: Site Walk — Fixtures and Installation
8
Walk the full fixture installation with approved plan — compare as-installed to approved locations
Inspector walks the property with the approved plan and compares each fixture's actual location to the plan. Fixtures not on the plan are scope creep — the inspector documents them and may require a revised permit before final sign-off, or may cite them as a violation. Per Houzz: "Failure to follow approved plan. This is the most common error made by homeowners doing their own work and general contractors alike. Deviating from the plan can result in major problems." For landscape lighting: fixture positions may have shifted from plan due to field conditions — small shifts (under 2 feet) are generally accepted; significant relocations or additions require review.
9
Verify all fixtures are energized and lit during the inspection
Inspector checks that every fixture in the installation is operational. A dead fixture at final inspection is a failure — even if the inspector believes it's just a burned lamp. Either the fixture is not working (code violation: NEC 411 requires the system to be operational) or the lamp failed (replace before calling for final). Turn on all transformer zones before the inspector arrives and walk the full installation to confirm every fixture is lit.
10
Check fixture listing marks on a sample of installed luminaires
Inspector spot-checks fixture labels for UL or ETL wet-location listing marks. NEC 411.4 requires all luminaires to be listed. For fixtures whose labels have degraded or were replaced: have listing documentation available per the wet location listing requirements. Inspector does not typically check every fixture but will check fixtures that appear unlabeled or suspect.
11
Probe cable depth at accessible surface points (especially near fixtures where trench was shallowest)
Even after underground inspection, some inspectors re-probe cable depth at final — particularly near fixtures where the cable typically comes close to the surface. Inspector uses a thin probe near each fixture stake. The 6-inch minimum from soil surface applies throughout the run. Fixture stake connections are the most commonly shallow points because the installer pulled the cable taut to the fixture location without maintaining consistent depth at the endpoint. Verify depth at all fixture stakepoints before calling for final.
Phase 4: Special Locations
12
Measure pool setback for any fixtures near pool, spa, or fountain
If any fixture is within 15 feet of a pool, spa, or fountain, the inspector measures horizontally from the inside pool wall to the nearest fixture. 10-foot minimum required per NEC 411.4(2). Inspector uses a tape measure and records the measurement. Have your own tape measure and pool setback measurements pre-documented. Per the pool lighting clearance guide, the measurement is from the inside pool shell edge, not the coping or deck. Have the measurement done and documented before calling for final.
13
Check any wire runs exposed above grade — conduit protection, securing intervals
Any low-voltage cable that runs above grade (along a wall, across a deck) must be either: (1) installed per the approved conduit method shown on the plan; (2) secured per the wiring method requirements; or (3) protected against physical damage where subject to damage risk. Inspector checks that above-grade runs are protected as shown on the approved plan and that conduit is properly secured at required intervals.
Phase 5: Documentation Review and Sign-Off
14
Review load calculation — confirm total wattage within transformer rating
Inspector reviews the load calculation submitted with the permit. Confirms total connected wattage per zone does not exceed 80% of the transformer's rated capacity (the standard safe loading rule) and that the transformer's rated output does not exceed 25A per NEC 411. See the load calculation guide.
15
Sign off the permit card / enter approval in electronic system
If all items pass: the inspector signs the permit card at the Final Inspection line and records the approval in the jurisdiction's permit tracking system. The permit is now "Closed." Obtain a copy of the signed permit card or the electronic approval confirmation before the inspector leaves. This is the documentation that proves the permit is closed — essential for future property sale, future permits, and insurance records.

Documentation Required On-Site at Final Inspection

The inspector does not bring copies of your permit or approved plans — you are responsible for having them on-site. Missing documentation is a separate failure from any code violation, and it causes an otherwise compliant installation to fail inspection simply because the paperwork isn't there.

📜
Building Permit Card — The Physical Issued Permit
The permit card issued by the building department when the permit was approved. Some jurisdictions still use physical cards that must be posted at the site; others are fully electronic. Even with electronic systems, having the permit number, permit holder name, and project address immediately available when the inspector arrives prevents scheduling confusion. If the physical permit card is required in your jurisdiction and it is lost, contact the building department for a replacement before calling for final inspection.
📄
Approved Plan Set — The Stamped Set, Not a Copy of Your Working Drawings
The exact plan set that was submitted to and approved by the plan examiner, bearing the AHJ's approval stamp. Per Garden Grove CA: "The copy of the plans received have been reviewed and approved by the City. This is the set your inspector will refer to when conducting inspections on your project." If the stamped plan set has been lost, contact the building department — most jurisdictions maintain a copy and can provide a replacement, though some charge a fee. Do not present a working drawing or a photocopy as the approved plan set; the inspector will want to see the approval stamp.
Load Calculation — Total Wattage per Zone
The load calculation submitted with the permit, showing each fixture's wattage, the zone total, and the transformer's rated capacity. If the installed system differs from the permit submittal's fixture list (scope creep — fixtures added or changed), the load calculation must be updated to reflect actual installed load before final inspection. An outdated load calculation that doesn't match actual installed fixtures creates questions the inspector must resolve before sign-off. See the load calculation guide.
🔑
Listing Documentation — UL Product Pages for All Major Components
If any equipment's listing label is not legible — particularly for transformer or fixtures installed on a previous phase of work — have printed listing documentation from UL's Product iQ database (productiq.ulprospector.com) or ETL's equivalent. The product listing page shows the specific model, the applicable standards, and the listing scope. This documentation resolves listing questions on-site without requiring the inspector to make a separate determination. See the Portfolio model number lookup for Portfolio-specific model identification.
📏
Pool Setback Documentation — For Any Pool-Adjacent Fixture
If any fixture is within 15 feet of a pool, spa, or fountain, have a documented measurement from the inside pool shell edge to the nearest fixture — with a photograph showing the tape measure. This pre-documented measurement confirms compliance before the inspector measures and prevents disputes about reference points (inside shell vs coping vs deck edge). See the pool-adjacent section below and the pool lighting clearance guide.
💾
California Commercial Projects: Certificate of Installation (CEC-NRCI-LTO-E)
For nonresidential outdoor lighting in California, the California Energy Commission requires a Certificate of Installation (form CEC-NRCI-LTO-E) at final inspection. Per the CEC: "A copy of the completed signed and dated Installation Certificate must be posted at the building site for review by the enforcement agency in conjunction with requests for final inspection." The certificate documents that what was installed matches the Certificate of Compliance, with fields for both the permit set and any as-built set. Before an occupancy permit is granted, all outdoor lighting controls must also have acceptance testing documentation (Certificate of Acceptance). See the commercial finals section below.

The Scope Creep Problem: When Added Work Requires a Revised Permit Before Final

Scope creep — changes made during installation that go beyond the approved permit drawings — is the most common cause of final inspection delays for landscape lighting projects. Understanding when a change requires a revised permit and when it doesn't prevents expensive last-minute discoveries.

Why Changes During Installation Happen — and Why They Create Problems

During landscape lighting installation, changes from the approved plan are almost universal: the homeowner asks for two more path lights "while you're here," a spotlight location shifts to avoid a tree root, a wire route changes to avoid an irrigation line discovered during digging. Per the Mike Holt forum discussion among licensed electrical inspectors about plan changes: "I think it would be pretty standard that anything that increases the load will require a plan check revision to be approved by the AHJ." And per the Houzz guide: "Sometimes a new permit will need to be pulled, or a change to the existing permit will need to be officially submitted. In any event, deviations to the plan will need to meet both planning and building codes."

✓ Changes That Typically Don't Require a Revised Permit

Minor position shifts: A fixture that moved 1–3 feet from its planned position due to a tree root, irrigation line, or terrain obstacle — when the shift doesn't affect pool setback compliance or bring the fixture near a new hazard.

Wire routing changes: A wire run that takes a different path through the property (around an obstacle) but connects the same fixtures to the same transformer zones shown on the plan.

Fixture substitution with identical specification: Replacing a planned fixture with a different model that has identical wattage, type, and wet-location listing. The fixture schedule changes but the load calculation doesn't. Best practice: document the substitution in writing.

Depth of burial adjustment: Burying cable deeper than planned (10 inches instead of 6 inches) is over-compliant and doesn't require plan revision.

✗ Changes That Require a Revised Permit Before Final

Adding fixtures beyond the approved count: Any fixture added during installation that was not on the approved plan increases the connected load and changes the as-built condition from the approved permit. The Mike Holt CA perspective: "anything that increases the load will require a plan check revision." Contact the building department and submit a plan revision before the final inspection.

Fixture locations near pool: Any fixture repositioned to within 15 feet of a pool, spa, or fountain when the approved plan showed it farther away requires pool setback verification — which may require plan revision if the original plan didn't address pool proximity.

Adding a transformer zone or second transformer: New circuit not shown on approved plan.

Wire route crossing a utility easement not shown on plan: Requires disclosure to the easement holder and potential plan revision.

⚠ How to Handle Scope Creep Before Calling for Final If you realize you have scope creep (fixtures or circuit elements not on the approved plan) after installation is complete: contact the building department and describe the change. Ask whether a plan revision is required or whether the change can be accepted at final inspection as a documented deviation. Do not try to hide the change — the inspector will compare the installation to the approved plan and will find discrepancies. Per the Houzz guide: "don't wait to the end, as this may delay your certificate of completion (CC) or occupancy (CO)." Resolving scope creep proactively before final is dramatically faster and cheaper than discovering it at final inspection.

Commercial Outdoor Lighting Finals: Additional Requirements Beyond Residential

Commercial landscape and outdoor lighting installations face final inspection requirements that residential installations don't — primarily through state energy codes and the Certificate of Installation/Acceptance framework. California's Title 24 is the most documented example, but similar frameworks exist in other states that have adopted energy codes for commercial buildings.

California Title 24 — Certificate of Installation (CEC-NRCI-LTO-E)

For nonresidential outdoor lighting in California (commercial, industrial, multi-family over 3 stories, hotel/motel), the California Energy Commission requires documentation demonstrating that the installed system matches the permitted design. The Certificate of Installation (form CEC-NRCI-LTO-E) must be:

  • Completed and signed by the person with an approved license responsible for the installation
  • Posted at the building site for review by the enforcement agency at final inspection
  • Submitted to the enforcement agency after installation and before receiving the final occupancy approval

The CEC documentation distinguishes between: (1) "Installed features exactly match design on permitted Certificate of Compliance" — if true, the standard installation certificate suffices; and (2) conditions where the as-built set differs from the permit set — in which case "the Certificate of Compliance should be revised to confirm as-built conditions comply." This distinction makes the California Title 24 documentation framework the most explicit codification of the scope-creep problem for commercial outdoor lighting.

Certificate of Acceptance for Lighting Controls

Per the CEC: "Before an occupancy permit is granted for a new building or space, or a new lighting system serving a building, space, or site is operated for normal use, all outdoor lighting controls serving the site shall be certified as meeting the Acceptance Requirements for Code Compliance. A Certificate of Acceptance shall be submitted to the enforcement agency." For commercial landscape lighting with automated controls (timers, photocells, occupancy sensors), the acceptance testing must be completed and documented before the final occupancy approval.

Commercial vs Residential Final: What's Different

RequirementResidential Landscape LightingCommercial Outdoor Lighting
Certificate of Installation Not required (CA residential exemption) Required (CA CEC-NRCI-LTO-E) — must be on site at final
Certificate of Acceptance Not required for residential Required for all lighting controls (timers, photocells, sensors)
Energy code compliance documentation Not required for standard residential Required — photometric plan showing compliance with energy code wattage limits
Photometric plan at final Required if permit submittal included photometric plan; inspector compares as-built positions to calculated values Required — inspector may verify illuminance levels with a light meter for commercial projects
Licensed contractor at final Not typically required if homeowner pulled permit; contractor license verification if contractor pulled permit Required — contractor's license must be verified; in CA the Certificate of Installation requires signed certification by licensed person
California Title 24 requirements apply to nonresidential, hotel/motel, and high-rise residential. Similar frameworks exist in states that have adopted ASHRAE 90.1 or the IECC for commercial buildings. Always verify specific requirements with your AHJ. Scroll right on mobile.

Pool-Adjacent Lighting Final: Additional Documentation and Measurements Required

Pool-adjacent landscape lighting finals require specific additional documentation and measurements that residential landscape lighting finals without pools don't. Prepare these before calling for final — they take 30 minutes on-site but prevent the most common pool-adjacent final failure.

Pre-Final Documentation for Pool-Adjacent Installations

  1. Horizontal distance measurement from inside pool shell to each nearby fixture. Measure from the inside face of the pool shell (not the coping, not the deck edge) to the centerline of each fixture that is within 15 feet of the pool. Document on a diagram showing the pool outline, each fixture's position, and the measurement to each from the pool edge. Minimum: 10 feet for standard landscape luminaires per NEC 411.4(2). Photograph the measurement with a tape measure visible between the pool edge and the fixture. This photo documentation is your defense if the inspector measures differently.
  2. Transformer listing verification for pool-adjacent systems. Standard Portfolio or Hampton Bay landscape transformers are NOT listed for pool and spa use. If any fixture is within 5–10 feet of the pool and is being approved under the Article 680 compliance path, the transformer must be listed for pool/spa use with secondary-side GFCI protection. Document the transformer's specific listing designation and confirm it covers pool-area use. See the pool lighting clearance guide.
  3. Secondary-side GFCI documentation for 5–10 foot fixtures. For any fixture within the 5–10 foot zone that is permitted under the Article 680 path, document the secondary-side GFCI protection method. The GFCI at the primary transformer outlet does NOT satisfy this requirement — the isolation transformer electrically separates the circuits. See the GFCI requirements guide.
  4. Photometric plan showing fixture positions relative to pool. For commercial pool-adjacent lighting, have the photometric plan updated to show as-built fixture positions relative to the pool boundary with the setback measurements annotated.

The Simplest Pool-Adjacent Final Strategy: The 10-Foot Rule. If you keep every standard landscape luminaire at least 10 feet from the inside edge of every pool, spa, and fountain, you avoid the entire Article 680 compliance path complexity. No secondary-side GFCI required. No special transformer listing required. No pool-area compliance documentation beyond the measurement confirmation. The additional documentation and engineering required for fixtures within the 5–10 foot zone consistently costs more in design, specialty equipment, and inspection time than simply designing the landscape lighting layout to maintain the 10-foot clearance everywhere. When the homeowner wants path lights "right next to the pool," the correct answer is "here's what the 10-foot line looks like" — then design beautifully within that boundary.

Complete 18-Item Pre-Final Checklist Organized by Inspector Walk Sequence

Run through this checklist in the 24 hours before calling for final inspection. Items are in the same order the inspector will check them — so your pre-inspection walk mirrors exactly what happens during the inspection. Check every box before scheduling.

Administrative — Do Before Calling for Inspection
Permit card is on-site, accessible, and matches the current permit number
Confirm the physical permit card (or electronic equivalent) is available at the property. Verify the permit number on the card matches the permit number you used when scheduling the inspection.
AHJ-stamped approved plan set is on-site — not a copy, the stamped set
The plan set with the building department's approval stamp. This is what the inspector uses for the as-installed comparison. Have it in a weatherproof sleeve, organized by sheet.
All prior inspection stages (underground, rough-in) are documented as approved on permit card
Check the permit card records or electronic system to confirm each required prior inspection stage shows an approval. If any prior stage is missing, schedule and pass that stage before calling for final.
No scope creep: as-installed system matches the approved plan, or plan revision has been submitted and approved
Walk the installation against the plan. Every fixture on the plan is installed. No fixtures are installed that aren't on the plan. All wire routes follow the plan (or minor deviations are documented). If scope creep exists, resolve it with the building department before calling for final.
Load calculation updated to reflect as-installed fixture list (if any changes from permit submittal)
If any fixtures changed during installation (different wattage, additional fixtures, removed fixtures), update the load calculation to reflect the actual installed system. Have the updated calculation on-site with the other documentation.
Supply Side — Check Day Before Final
Transformer mounting height measured and confirmed at minimum 12 inches above grade per label
Measure from the soil surface to the bottom of the transformer housing. Minimum height is on the transformer's label — typically 12 inches. Verify from soil (not mulch) surface. See the transformer mounting code requirements.
GFCI outlet tests correctly: TEST removes power, RESET restores it
Plug in a test load (phone charger, lamp). Press TEST — load must lose power. Press RESET — power must restore. If GFCI doesn't trip on TEST, it's failed or the outlet isn't GFCI-protected. Replace before calling for final. See the GFCI requirements guide.
While-in-use outlet cover closes fully with transformer plug inserted
With the transformer plugged in, close the outlet cover. It must close completely. If it doesn't close, install a while-in-use (bubble) cover — $8–15 at any hardware store. This is the while-in-use cover requirement per NEC 406.9(B)(1).
Transformer listing label is legible — or listing documentation is printed and on-site
Read the UL or ETL listing mark on the transformer. If it's illegible, print the listing page from productiq.ulprospector.com using the transformer's model number. See the Portfolio model lookup.
Site Walk — Check Same Day as Final
All transformer zones are on and every fixture is lit
Turn on all zones. Walk the full installation and confirm every fixture is illuminated. Replace any dead lamps before the inspector arrives — not after they've noted the failure. A dead fixture at final is a deficient installation item.
Probe cable depth at fixture stake points and at the end of each run (shallowest points)
The ends of cable runs near fixtures are typically shallowest. Probe at each fixture stakepoint with a thin rod and measure from soil surface to cable. Minimum 6 inches. Re-bury any point that measures less. See the burial depth code guide.
All fixture listing marks are legible on a spot check of installed luminaires
Check labels on 20% of installed fixtures. Any fixture with an illegible or missing listing mark should have listing documentation printed and available.
Any above-grade cable runs are in approved conduit, properly secured
Verify any exposed cable matches the conduit method shown on the approved plan. Confirm conduit is secured at required intervals and that no cable is exposed without approved protection.
Pool Proximity — Required for Any Fixture within 15 Feet of Pool
Pool setback measured from inside pool shell — all fixtures 10+ feet from pool edge
Measure from inside pool shell edge to nearest fixture. Document with tape measure photo. Minimum 10 feet per NEC 411.4(2). If any fixture is closer, either relocate it or implement the Article 680 compliance path with secondary-side GFCI. See the pool lighting clearance guide.
Secondary-side GFCI documentation available for any fixture within 5–10 foot zone
If any fixture is in the 5–10 foot zone under Article 680 compliance path, confirm secondary-side protection is documented. The GFCI at the primary outlet does not satisfy this requirement. See the GFCI requirements guide.
Commercial Projects — California Title 24 and Similar
Certificate of Installation (CEC-NRCI-LTO-E) completed, signed, and posted on site
For California nonresidential outdoor lighting: the installation certificate must be completed by the licensed installer, signed, dated, and posted at the building site. This must be on-site for the final inspection. If the as-built differs from the permitted design, the Certificate of Compliance must be revised before the Certificate of Installation can be completed.
Certificate of Acceptance completed for all lighting controls (timers, photocells, sensors)
For California nonresidential projects with lighting controls: acceptance testing must be completed and the Certificate of Acceptance submitted to the enforcement agency before final occupancy approval. All newly installed outdoor lighting controls require acceptance testing regardless of the scale of the project.

Five Failures Discovered at Final That Were Clean at Rough-In

These are the conditions that consistently pass rough-in inspection but fail final — because they either didn't exist at rough-in, weren't the focus of the rough-in inspection, or developed between rough-in and final.

1. Dead Lamps at Final Inspection

A fixture that was operational at rough-in may have a burned lamp by the time final inspection is called — if weeks or months elapsed between installation and final. The inspector finds a non-illuminating fixture, documents it as a deficient installation item, and the permit remains open. Fix: walk the full installation with all zones on before the inspector arrives. Replace every dead lamp. This is a $5–20 fix that takes 3 minutes per fixture when identified before inspection and creates a correction notice when found by the inspector.

2. GFCI Outlet Failure After Months of Outdoor Exposure

GFCI outlets that test correctly at rough-in sometimes fail their test function after months of outdoor exposure — moisture ingress into the mechanism can cause the GFCI to stop tripping on the TEST button even though it continues to pass power. The inspector tests the GFCI at final: presses TEST, outlet doesn't lose power — immediate failure. Fix: test the GFCI the day before calling for final inspection using the TEST/RESET procedure. If it doesn't trip on TEST, replace the outlet before calling for final.

3. Scope Creep Discovered When Plan Is Compared to Installation

Fixtures added "while the crew was there" that weren't on the approved plan are clean at rough-in (the rough-in inspection doesn't compare fixture positions to the plan in the same detail) but become a problem at final when the inspector walks the property with the plan and counts fixtures. Per the Mike Holt forum: "It is on the plans, then many inspectors will require it's presence based on that." The reverse is equally true — a fixture that isn't on the plan will be flagged. Fix: resolve all scope creep with the building department before calling for final.

4. Pool Setback Violation Added After Rough-In

The pool setback zone is typically not the focus of rough-in inspection for the primary landscape lighting work. A fixture moved during installation to a position within 10 feet of the pool — or a fixture added near the pool that wasn't on the original plan — appears at final when the inspector measures the pool setback for the first time in the inspection process.

5. Missing or Incorrect While-In-Use Cover at Transformer Outlet

The while-in-use cover at the transformer outlet is frequently overlooked between rough-in and final — installers sometimes remove it temporarily and forget to reinstall it, or the original outlet cover was standard (not while-in-use) and the violation was missed at rough-in. At final, with the transformer plugged in, the inspector tries to close the cover and finds it won't close — immediate failure. Fix: install the correct while-in-use bubble cover before calling for final and confirm it closes completely with the transformer plug inserted.

The dead lamp at final is the one that frustrates me most because it is genuinely a two-minute fix that becomes a correction notice because nobody walked the installation before calling for final. I have seen landscaping contractors call for final on a 22-fixture system, have the inspector show up, and get three correction notice items for three dead lamps that burned out during the two months between installation and inspection. Two months of accruing re-inspection fees and permit-open status — for three $8 lamps. Walk the installation with all zones on the day before you call for final inspection. Every time. Without exception. It is the single cheapest and most productive pre-final step available.

After Final Sign-Off: Permit Closeout and Record Keeping

The inspector's signature on the permit card is not the end of the process — it's the beginning of a record-keeping step that protects you at property sale, future permit applications, and insurance claims for years to come.

Immediately After Final Approval

  1. Obtain a copy of the signed permit card or electronic approval confirmation. Ask the inspector before they leave for a signed copy or confirm you can obtain one at the building department office. Some jurisdictions email a digital approval confirmation automatically; others require you to visit the office or download from their portal.
  2. Verify the permit status in the building department's records. Check the jurisdiction's online permit tracking system (if available) to confirm the permit shows "Closed" or "Final" status. Some systems update immediately; others take 1–5 business days. If the status still shows "Open" after a week, call the building department to request a status update.
  3. Create the as-built documentation package. After final approval, document the actual installed system using the methods described in the as-built diagram requirements guide. The as-built documents what was installed — which may differ from the approved plan in minor ways that were accepted at final. The as-built is what future contractors, future owners, and insurers will rely on to understand the system.

Long-Term Record Keeping

Maintain a permanent property documentation file containing: the final approved permit card (copy); the as-built diagram; all listing documentation for major components; any HOA approval letters; and the final inspection approval confirmation. Per the guidance documented in the correction notices guide: this documentation package is what prevents open permit discoveries at property sale, supports insurance claims, and enables future contractors to work safely around existing buried infrastructure. Store it with your home's other critical documents — not in the garage or attic where it may be lost.

Outdoor Lighting Final Inspection FAQ

I missed the underground inspection window and the trench is already backfilled. Can I still get a final inspection?

Not directly — the underground inspection must be passed before final can be approved. If the underground trench was backfilled before inspection, the building department will typically require re-excavation of representative sections to verify burial depth and cable type before approving the underground stage, which then allows the final inspection to proceed. The standard outcome: you contact the building department, explain that the trench was backfilled before inspection, and ask what sections they need to see excavated for the underground inspection. They will direct you to re-excavate specific points (often every 30–50 feet and at each fixture location) and call for underground inspection on the open sections. After the underground stage is approved on those sections, you can backfill and proceed to final. This is significantly more expensive than having the underground inspection done before backfilling — typically $200–500 in additional labor for re-excavation on a typical residential landscape lighting run. The prevention is simple: call for underground inspection before the trench is closed. For the complete buried-before-inspection discussion, see the inspection failure codes guide.

I added four more path lights after the permit was issued because the homeowner wanted them. What do I do before calling for final?

Contact the building department before calling for final and describe the scope change: "We added four path lights to the installation not shown on the approved plan, total added wattage X watts, all fixtures are [same model as other approved fixtures] with identical listing." Ask whether a plan revision is required or whether the addition can be approved as a field change at final inspection. The answer depends on: (1) whether the added load brings the system above the approved transformer capacity; (2) whether the added fixtures are near the pool and change any setback calculations; and (3) your jurisdiction's policy on minor additions — some AHJs accept minor additions as long as total load remains within the approved transformer rating and no special locations are affected. If a plan revision is required, submit it and wait for approval before calling for final — calling for final with unapproved scope additions is the most common source of plan-comparison failures at final inspection. The addition almost certainly won't cause a compliance problem, but it must be documented properly.

My landscape lighting permit was issued eight months ago and I'm just now calling for final. Will there be a problem?

Potentially yes — most permits have an expiration clause based on time without inspection activity. Many jurisdictions expire permits after 6–12 months without a final inspection being completed. Contact the building department before calling for final and ask whether the permit is still active. If the permit is still active (some jurisdictions have longer windows or have been liberal about expiration enforcement), call for final as normal. If the permit has expired, you will need to go through the permit renewal process — typically paying a renewal fee and possibly requiring re-inspection of prior stages. For buried cable on an expired permit, the inspector at final may require re-verification of underground work (probe testing) even if the underground inspection was completed months ago. The cost of permit renewal (typically 25–100% of the original permit fee) and potential re-inspection is the cost of allowing a permit to expire. Contact the building department and get the current permit status before scheduling any inspection after an 8-month gap. See the correction notices guide for the permit expiration timeline and consequences.
