San Francisco's Solar Energy: The Rules That Matter
Every city handles solar energy a little differently. In San Francisco, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Expedited Solar Permitting
Small residential solar systems of 4 kilowatts or less are issued over the counter in San Francisco once the application is complete, and expedited installations get just one inspection scheduled within three business days.
Key details: Over-the-counter threshold: 4 kW or less. Inspection scheduling: Within 3 business days. Inspection window: Two hours. Failed inspection: Requires re-inspection.
A system larger than 4 kilowatts, or one flagged for a health or safety issue, does not qualify for over-the-counter issuance and must go through standard Electrical Division review and full permit processing instead.
HOA Restrictions
California Civil Code §714 (the Solar Rights Act) prohibits HOAs and CC&Rs from effectively banning solar energy systems. Any restriction that increases cost by more than $1,000 or decreases efficiency by more than 10% is void and unenforceable in San Francisco and statewide.
Key details: State Law: CA Civil Code §714 (Solar Rights Act). HOA Limits: Cannot ban solar or increase cost >$1,000. Efficiency: Cannot reduce efficiency >10%. Aesthetic Rules: Reasonable requirements allowed. Enforcement: Restrictions are void if non-compliant.
HOA restrictions that violate the Solar Rights Act are void and unenforceable. Homeowners may seek legal remedies if an HOA unlawfully blocks a solar installation.
If you are coming from a city with tighter rules, you will find San Francisco gives residents more flexibility on hoa restrictions.
Panel Permits
San Francisco requires an electrical permit before installing or altering any solar energy system, with fees set by the Building Code's Table 1A-E electrical permit schedule, plus other permits for related work.
Key details: Permit type: Electrical permit. Fee schedule: Section 110A Table 1A-E. Historic buildings: Full permit + Planning review. Minor alterations: No new permit needed.
Installing or altering a solar energy system without the required electrical permit is unpermitted work, enforceable by the Department of Building Inspection through notices of violation, correction orders, and after-the-fact permit penalties.
The Bottom Line
San Francisco's solar energy rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming San Francisco is broadly strict or permissive.
