Summary
Antioch issues residential rooftop solar permits under the California Solar Rights Act (Civil Code 714) and AB 2188 streamlined-permit mandate. Standard systems are processed within 3 business days, often same-day via the SolarAPP+ automated plan review.
(a) The implementation of consistent statewide standards to achieve the timely and cost-effective installation of solar energy systems is not a municipal affair, as that term is used in Section 5 of Article XI of the California Constitution, but is instead a matter of statewide concern. It is the intent of the Legislature that local agencies not adopt ordinances that create unreasonable barriers to the installation of solar energy systems, including, but not limited to, design review for aesthetic purposes, and not unreasonably restrict the ability of homeowners and agricultural and business concerns to install solar energy systems.
(b) A city or county shall administratively approve applications to install solar energy systems through the issuance of a building permit or similar nondiscretionary permit. Review of the application to install a solar energy system shall be limited to the building official's review of whether it meets all health and safety requirements of local, state, and federal law. The requirements of local law shall be limited to those standards and regulations necessary to ensure that the solar energy system will not have a specific, adverse impact upon the public health or safety. However, if the building official of the city or county makes a finding, based on substantial evidence, that the solar energy system could have a specific, adverse impact upon the public health and safety, the city or county may require the applicant to apply for a use permit.
(g) (1) On or before September 30, 2015, every city, county, or city and county, in consultation with the local fire department or district and the utility director, if the city, county, or city and county operates a utility, shall adopt an ordinance, consistent with the goals and intent of subdivision (a), that creates an expedited, streamlined permitting process for small residential rooftop solar energy systems.
(h) For a small residential rooftop solar energy system eligible for expedited review, only one inspection shall be required, which shall be done in a timely manner and may include a consolidated inspection, except that a separate fire safety inspection may be performed in a city, county, or city and county that does not have an agreement with a local fire authority to conduct a fire safety inspection on behalf of the fire authority.
Full Breakdown
Residential rooftop solar photovoltaic (PV) permits in Antioch are issued by the Community Development Department Building Division under state-mandated streamlined standards. 5 (AB 2188, 2014) requires every city and county to adopt an ordinance creating an expedited, non-discretionary permit process for small residential rooftop PV systems (10 kW AC or less, roof-mounted, not involving structural upgrades beyond routine reinforcement). California Civil Code 714 (Solar Rights Act) further prohibits local governments and HOAs from unreasonably restricting solar installations. S. Department of Energy's NREL, which issues instant permits for code-compliant standard installations.
For systems that do not qualify for SolarAPP+ (ground-mount, non-standard, battery storage combo, structural upgrade needed), standard plan review applies with a 3-business-day turnaround for complete applications. Inspections include a rough-in (if structural) and final combination inspection (electrical, building). Required plans include a site plan, roof plan with module layout, electrical single-line diagram showing equipment and overcurrent protection, and structural calculations or a signed affidavit for systems that meet the AB 2188 standard prescriptive path. The California Electrical Code (Title 24 Part 3) and NEC Article 690 govern PV wiring.
0) from PG&E changed export compensation effective April 2023, significantly reducing payback for export-only systems; many new installs include battery storage to maximize self-consumption. The federal Residential Clean Energy Credit provides a 30% tax credit through 2032.
