Quick answer
A solar permit is required for photovoltaic systems in unincorporated Orange County, and the county's submittal bulletin spells out the ancillary permits too: an electrical permit for a panel upgrade and a plumbing permit for a plumbing vent relocation. The Board of Supervisors adopted Ordinance No. 15-012 on August 25, 2015 adding Section 7-1-81 to the county code, creating the expedited permitting process for small residential rooftop solar required by AB 2188 and the California Solar Rights Act. The county has since adopted SolarAPP+ under SB 379, so registered licensed contractors can get code compliance verified and a permit issued in real time for roof-mounted retrofit systems on existing permitted homes, then apply through myOCeServices using the SolarAPP+ approval number. This applies to unincorporated Orange County only; the county's 34 incorporated cities run their own building departments.

How to apply in Orange County
In Orange 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).
- For Orange County, 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).
- For Orange County, 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).
- For Orange County, 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
In Orange County, 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.
- In Orange County: 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).
- In Orange County: 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)).
- In Orange County: pV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
- In Orange County: 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).
- In Orange County: 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)).
- In Orange County: 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 Orange County permit portal or by phone at 714-667-8888.

- Where do you apply for a solar permit in Orange County?
- You can apply through the Orange County permit portal or contact the OC Public Works, OC Development Services (Building & Safety) directly. The links are listed on this page.
- Can a homeowner pull a solar permit themselves in Orange County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner from contractor licensing under section 7044 when they personally perform all the work on their own property, or any work they do not perform themselves is done by their own employees paid only wages, and none of the improvements are intended or offered for sale. It also exempts an owner who directly contracts with licensed contractors for each trade, as long as no more than four of the single-family residential structures involved are intended or offered for sale in a calendar year; this route does not apply if the owner instead contracts with a general contractor for the construction. A homeowner may also improve their own principal residence without a license, as long as the work is done before any sale, they have actually resided there for the 12 months before completion, and they have not used this exemption on more than two structures more than once in any three-year period. 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 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 civil penalty of up to $500. Confirm how Orange County applies this before you apply.
