Solar site surveys in Los Angeles

Roof, attic and service panel captured in one visit, with the plan set built for the Los Angeles AHJ you submit into and the utility that serves the address.

Short answer

Los Angeles-area solar permitting is split among many AHJs. LADBS covers the City of LA, LA County Public Works covers unincorporated areas and contract cities, and cities such as Long Beach, Pasadena, Glendale and Burbank run their own building departments. The serving utility also varies by address: LADWP serves the City of LA, SCE serves most surrounding cities, and Pasadena, Glendale and Burbank run municipal utilities with their own solar rules.

What changes in Los Angeles

California state rules apply here, plus whatever the local AHJ amends.

CA · LOS ANGELESLos Angeles
Code stack
2023NEC 2023National Electrical Code · effective Jan 1, 2026. The 2025 California Electrical Code (Title 24, Part 3) adopts the 2023 NEC with California amendments and applies statewide from January 1, 2026. It replaced the 2022 edition, which was based on the 2020 NEC. Some cities, such as Los Angeles, publish their own amended local version.1,2,3,4
2025CRC 2025The 2025 California Residential Code (Title 24, Part 2.5) is based on the 2024 IRC with state amendments. It covers one- and two-family dwellings and took effect January 1, 2026.5,4
2025CFC 2025The 2025 California Fire Code (Title 24, Part 9) is based on the 2024 IFC with state amendments and took effect January 1, 2026. Local fire agencies may adopt further amendments.6,4
2025Energy Code 2025Since the 2019 standards took effect in 2020, California has required solar PV on newly built low-rise homes. Under the 2025 Energy Code, most new single-family homes still need PV (Section 150.1(c)14) and must be battery-ready in many cases. The code applies to permit applications filed on or after January 1, 2026.7,8,9
Rooftop fire access. For homes, the CRC sets firefighter access rules for rooftop PV. There must be at least two 36-inch pathways from eave to ridge on separate roof planes, with at least one on the street or driveway side. The clear setback on each side of a horizontal ridge is 18 inches when the array covers 33% or less of the plan-view roof area and 36 inches when it covers more. No panels may sit below an emergency escape opening. These provisions were R324.6 in the 2022 CRC, and City of Berkeley's 2025-code checklist cites them as R329.6. Local fire departments such as LAFD may add their own requirements.10,11,12

Climate and site factors

Hillside and fire zones

In Very High Fire Hazard Severity Zones, LADBS requires Class A-rated PV and racking. Ground-mounted arrays in the hillside grading area need a grading pre-inspection and a 10-foot brush-free clearance.12

Separate utility approval

LADBS does not route applicants to LADWP, so installers must get LADWP's interconnection approvals themselves, alongside the city permit.12

Historic buildings

In the City of LA, solar on historic buildings requires a signed advisory notice before the permit issues, but no separate City Planning clearance.12

Earthquake risk

The USGS describes the Los Angeles region as having the highest seismic risk in the United States, with many active faults. Ballasted arrays on flat roofs require SEAOC seismic and wind analysis in the City of LA.13,12

Permitting in Los Angeles

The main AHJs, and how the rest of the metro splits up.

Los Angeles Department of Building and Safety (LADBS)

LADBS issues online electrical permits for qualifying rooftop PV on one- and two-family homes: 10 kW or less, 120/240 V single-phase, and a service panel of 225 A or less. Larger or nonstandard systems go to counter or regular plan check. A separate building permit is waived for many light, flush-mounted arrays.12

Official page ↗

Los Angeles Fire Department (LAFD)

LADBS requires rooftop access under LAFD Requirement No. 96. Rooftop PV on one- and two-family homes skips separate LAFD approval if it meets LAFD's reference requirements form, and LADBS inspectors check those items in the field.12

Official page ↗

LA County Public Works, Building and Safety

LA County Public Works handles permits for unincorporated areas and for cities that contract with the County. Plans can be submitted online through EPIC-LA (unincorporated) or the BSOP web application (contract cities), and small plans can be reviewed over the counter.14,15

Official page ↗

Across the metro

Each incorporated city is its own permitting authority and may adopt local amendments to the 2025 state codes, as Long Beach and Culver City have. LA County Public Works serves unincorporated communities and contract cities.16,17,15

California-wide rules that still apply

Utilities and interconnection

LADWP provides electricity inside the City of Los Angeles, and SCE serves most other cities and unincorporated areas in the region. Pasadena, Glendale and Burbank run their own municipal electric utilities with separate interconnection processes.24,25,26,27

Southern California Edison SCE

SCE is the investor-owned utility for much of central, coastal and Southern California, including most Los Angeles-area cities outside the City of LA. It interconnects rooftop solar under Rule 21, and new customers go on the Solar Billing Plan.25,28

Interconnection page ↗

Los Angeles Department of Water and Power LADWP

LADWP is the City of Los Angeles's municipal utility and sets its own solar rules outside the CPUC net billing tariff. It runs its own tiered interconnection process: Type 1 covers PV and battery projects up to 30 kW.24,29

Interconnection page ↗

Pasadena Water and Power PWP

PWP is Pasadena's municipal utility. Installers apply through PowerClerk, PWP reviews and inspects the system, and PWP installs a bi-directional meter before granting permission to operate.26

Interconnection page ↗

Glendale Water & Power GWP

GWP is Glendale's municipal utility and still offers net energy metering. Interconnection and NEM applications go through PowerClerk with the plan set attached.30

Interconnection page ↗

Burbank Water and Power BWP

BWP is Burbank's municipal utility. Installers get a meter spot and confirmation number from BWP before pulling a city permit. Permits filed on or after January 1, 2026 fall under BWP's Solar Net Billing program.27,31

Interconnection page ↗
Export compensation. Since April 15, 2023, new PG&E, SCE and SDG&E solar customers take service on the CPUC Net Billing Tariff. It credits exports at hourly values from the Avoided Cost Calculator, which are usually below retail rates, and older NEM customers keep their tariff for 20 years from interconnection. Municipal utilities differ: as of September 2026, LADWP and GWP run their own net metering programs, SMUD pays a flat export rate, and Burbank moved new permits to avoided-cost net billing on January 1, 2026.32,33,27,30

Los Angeles solar survey FAQ

Who issues solar permits in Los Angeles?

LADBS issues permits inside the City of Los Angeles. LA County Public Works handles unincorporated areas and contract cities, and other cities such as Long Beach, Pasadena and Glendale have their own building departments. Confirm the jurisdiction from the parcel address.12,15

Can a City of LA rooftop solar permit be issued online?

Yes, for qualifying systems. LADBS issues online permits for rooftop PV of 10 kW or less on one- and two-family homes that meet its electrical criteria, and other systems go through counter or regular plan check.12

Does NEM 3.0 apply to LADWP customers?

No. The CPUC Net Billing Tariff applies to PG&E, SCE and SDG&E. LADWP is a municipal utility that runs its own net energy metering and interconnection program, so check LADWP's current terms.32,34

Does LAFD need to approve residential rooftop solar?

Usually not separately for one- and two-family homes, if the design meets LAFD's reference requirements and the plans say so. LADBS inspectors verify those fire access items during inspection.12

Which utility serves my address in the LA area?

Inside the City of Los Angeles it is LADWP, and most surrounding cities are served by SCE. Pasadena, Glendale and Burbank have their own municipal utilities, each with its own solar application process.24,25,26
