Full Breakdown
The county's Rooftop Solar Ordinance (Title 9, Division 32) creates a streamlined ministerial permit for small residential rooftop solar energy systems (SRR-SES) up to 10 kW AC or 30 kW thermal on single-family or duplex homes. Systems must be roof-mounted, code-compliant, and not exceed the maximum legal building height. Complete applications are reviewed the next business day and must be approved or denied within three business days; silence past that window means the permit is deemed approved. Mobile-home installations and ground-mounted systems are excluded.
Violations & Fines
An incomplete or inaccurate application is rejected with a deficiency notice rather than expedited. A denial must be issued in writing within three days, stating the reason and any recommended fix.
