65850.7.
(a) The Legislature finds and declares all of the following:
(1) The implementation of consistent statewide standards to achieve the timely and cost-effective installation of electric vehicle charging stations 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.
(2) It is the intent of the Legislature that local agencies not adopt ordinances that create unreasonable barriers to the installation of electric vehicle charging stations and not unreasonably restrict the ability of homeowners and agricultural and business concerns to install electric vehicle charging stations.
(b) A city, county, or city and county shall administratively approve an application to install electric vehicle charging stations through the issuance of a building permit or similar nondiscretionary permit. Review of the application to install an electric vehicle charging station 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 electric vehicle charging station will not have a specific, adverse impact upon the public health or safety. However, if the building official of the city, county, or city and county makes a finding, based on substantial evidence, that the electric vehicle charging station could have a specific, adverse impact upon the public health or safety, the city, county, or city and county may require the applicant to apply for a use permit.
Full Breakdown
Sunnyvale has implemented a streamlined solar photovoltaic (PV) permit process consistent with AB 1236 and AB 379, which cap residential solar permit fees and require expedited online processing. Most small residential rooftop systems under 15 kW can receive same-day or next-day permit approval through the city's SolarAPP+ integration or online portal. Installations must meet the California Electrical Code, NEC 690 fire setbacks, and Title 24 Part 6 requirements. The 2019 update to Title 24 created the statewide Solar Mandate, which requires solar on most newly constructed single-family homes and low-rise multifamily. Ground-mount systems and battery storage may require additional zoning or fire review. Inspections focus on grounding, labels, rapid shutdown, and racking attachment.
