Summary
Rooftop or ground-mounted solar for a home in unincorporated Sacramento County needs only a standard planning application packet with safety certification and utility consent -- Accessory I systems are exempt from Design Review and processed as a routine building permit.
Standard application packet required for all planning applications. Required certifications for safety. No grid-intertied solar system shall be approved until evidence has been given to the Planning Director that the owner has obtained the consent of the utility company for the customer's intent to install an interconnected customer-owned generator. Off-grid systems are exempt from this requirement.
Full Breakdown
Zoning Code Section 3.6.6.C classifies home solar as an Accessory I facility, allowed in every zoning district. Installation requires the standard planning application packet plus required safety certifications, and no grid-tied system may be approved until the owner shows the Planning Director proof of the utility company's consent to interconnect (off-grid systems are exempt). Section 6.3.2.A.3 exempts all Accessory I solar facilities from the county's discretionary Design Review Program, so a typical residential rooftop array proceeds straight to a building permit rather than a use-permit hearing. Building permit fees for the panels themselves are set separately in County Code Section 16.90.030(M), scaled by system kilowattage.
Violations & Fines
Installing a grid-tied solar system without utility interconnection consent on file, or skipping the required safety certifications and application packet, exposes the installation to a building-permit stop-work order.
