LADBS Solar Permit Guide 2026: What Los Angeles Contractors Need to Know

The Los Angeles Department of Building and Safety is one of the highest-volume permit authorities in the United States. Contractors who pull permits in LA — whether through LADBS proper or through any of the 87 independent cities within Los Angeles County — need to understand both the LADBS system specifically and how it differs from surrounding city systems.

LADBS vs. independent LA County cities

This is the most important thing to get right before pulling any LA area permit. LADBS covers the unincorporated areas of Los Angeles County and the City of Los Angeles itself. But the County contains 88 cities, and 87 of them are incorporated with their own building departments. Burbank, Glendale, Pasadena, Long Beach, Santa Monica, Culver City, and dozens more all have independent permit systems entirely separate from LADBS.

Submitting a permit to LADBS for an address in Burbank is a rejection. Submitting to Burbank for an address in an unincorporated part of LA County is also a rejection. Confirming jurisdiction before every submittal in the LA basin is non-negotiable for avoiding this mistake.

LADBS solar permit process

Electronic submittal

LADBS accepts electronic plan submittals through the ePlan system. This is the preferred method and generally results in faster processing than over-the-counter submittals. First-time users of ePlan should plan for a learning curve on initial submittals.

Plan check timelines

Standard residential solar plan check at LADBS typically takes 10–21 business days for initial review. Correction cycles add time. Expedited plan check is available for an additional fee and can reduce initial review to 5–10 business days. Priority services are available for additional fees.

What LADBS requires for residential solar

• Title 24 compliance documentation (California energy code)
• Electrical single-line diagram showing all components, conductors, and disconnects
• Site plan with roof layout, setbacks, and equipment locations
• Structural details if rafter penetrations or structural attachments are involved
• Manufacturer specifications for all equipment

LADBS-specific note: LADBS has its own interpretation of some NEC requirements that may differ from other jurisdictions. Contractors who primarily work in other California cities and are expanding into LADBS territory for the first time often receive corrections on issues that weren't flagged elsewhere. Review the LADBS Information Bulletins before your first submittal.

Common LADBS solar corrections

• Rapid shutdown labeling not meeting LADBS-specific label location requirements
• Electrical plan not showing conductor sizing in conduit fill calculations
• Roof plan not dimensioning setbacks from all roof edges and penetrations
• Structural calculations not stamped for older homes with potential rafter deficiencies
• AC disconnect not shown at location meeting LADBS field access requirements

Tracking LADBS permits alongside LA County city permits

A contractor active in the LA basin typically works across LADBS and multiple independent cities simultaneously. Different portals, different login credentials, different status terminologies, different correction formats. The tracking overhead for a 15-permit active backlog spread across LADBS, Burbank, Pasadena, and Long Beach is significant.

Contractors who successfully scale in the LA market almost universally invest in centralized permit monitoring early. The alternative — someone manually checking six different portals twice a day — is expensive in coordinator time and still misses correction notices that come in after the last morning check.
