ADU Electrical Service & Power Release Inspection in Los Angeles
An ADU cannot be energized until it passes the electrical service inspection. First attempts fail 31.3% of the time in the City of Los Angeles, based on 15,566 inspections in LADBS records over the trailing 12 months.

of ADU Electrical Service / Power Release inspections fail on the first attempt in City of Los Angeles
Based on 15,566 first-attempt inspections, Trailing 12 months (2025-07-01 → 2026-07-01).
A first attempt counts as a failure when it drew a correction notice or the work was not ready when the inspector arrived.

Power release is the sign-off that lets the utility energize the unit. It depends on both your contractor’s work and the utility’s requirements, so failures usually trace back to panel details, grounding and bonding, or clearances rather than the wiring itself.
Why Electrical Service / Power Release inspections fail
Panel labeling and working clearance
Unlabeled circuits and insufficient working space in front of the panel are among the most common corrections.
Grounding and bonding
Improper grounding electrode connections or missing bonding is a frequent and code-critical failure.
Service sizing and meter details
A service or panel that does not match the approved load calculation, or meter/main details that do not meet utility spec, will be flagged.
AFCI/GFCI protection
Missing arc-fault or ground-fault protection where required is a common correction on newer residential work.
How to pass on the first attempt
Confirm the panel matches the approved load calculation and plan.
Label every circuit clearly and keep required working clearance in front of the panel.
Verify grounding electrode and bonding are complete and correct.
Confirm AFCI/GFCI protection everywhere the code requires it.
Check that meter, main, and service details meet the utility’s specification.
Have the approved electrical plan on site.
What the inspector checks
The inspector verifies the service and panel are installed to the approved plans and code — correct sizing, grounding and bonding, circuit protection, labeling, and clearances — so the unit can be safely energized and released for power.
What a failure costs you
A failed power-release inspection delays energizing the unit, which can cascade into every downstream task that needs power. Beyond the re-inspection, you may face coordination delays with the utility, making this one of the more schedule-sensitive failures.
Frequently asked questions
It is the inspection sign-off that authorizes the utility to energize the ADU’s electrical service. Without it, the unit stays without permanent power.
Usually panel labeling, working clearance, grounding/bonding, or circuit-protection details — small but code-critical items. See the reasons above.
The city inspection (LADBS) authorizes power release; the utility then energizes the service. Both sets of requirements have to be met, which is why coordination matters.
Beyond the re-inspection itself, a failed power release can hold up utility scheduling and any work that needs power, so it is worth getting right the first time.

This figure is a first-time pass rate — the share of permits whose first
attempt at this inspection type passed — computed directly from LADBS public inspection
records (9w5z-rg2h)
for the City of Los Angeles, over a rolling trailing 12 months, refreshed weekly. We only
count each permit's first attempt, so it shows how often work passes the first time.
A first attempt is a fail if it drew a correction or the work was not ready when the
