Quick answer

A permit is always required for solar in unincorporated Los Angeles County; there is no size below which one is waived. What size changes is the processing path. Chapter 68 gives an expedited process for small residential rooftop solar on one- or two-family dwellings, defined as photovoltaic systems no larger than 10 kilowatts alternating current or solar thermal systems for service water heating and pool heating no larger than 30 kilowatts thermal. A combined solar energy permit may be issued for photovoltaic systems covering all building and electrical work, with a separate plumbing permit if one is needed. Submittals use the county's standard electrical plan, a roof plan showing fire access pathways and labeling, the expedited structural criteria, and a signed Form A, B, or C affidavit confirming the array will not go on an unpermitted structure. A single combination inspection covers the structural, electrical, and plumbing components.

Who is pulling this permit?

Before you sign, ask the contractor:

  • Who pulls the permit, you or me, and is the permit fee included in the bid?
  • Which inspections will this job need, and who meets the inspector on site?
  • Is your contractor license active in this locality, and under which business name?

How to apply in Los Angeles County

A rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.

What most solar permit applications include:

  • Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
  • The plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
  • Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
  • The site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
  • The one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
  • Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
  • Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit

Inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.

  1. Where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
  2. The inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
  3. PV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
  4. Bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
  5. At the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
  6. Utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Los Angeles County permit portal or by phone at 626-458-3173.

Can a homeowner pull a solar permit themselves in Los Angeles County?
Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner-builder from contractor licensing when the owner personally performs the work, or uses only wage employees, on their own property and does not intend the improvements for sale. A homeowner may also directly hire licensed trade contractors for up to four single-family residences a year, or improve their own principal residence without a general contractor's license, as long as they have actually lived there for the 12 months before the work is finished. Selling a self-built structure within one year of completion creates a rebuttable presumption that it was built for sale, which defeats the exemption, and selling five or more structures within a year makes that presumption conclusive. Separately, every city or county that requires a building permit must also require the applicant to file a signed statement giving their contractor license number or the basis of their claimed exemption; a false or missing statement carries a $500 civil penalty. Confirm how Los Angeles County applies this before you apply.
