Summary
Union City administratively approves complete small residential rooftop solar applications and limits review to one consolidated inspection, implementing the state Solar Rights Act's expedited permitting mandate for systems up to 10 kW AC.
Upon confirmation by the Building Official of the application and supporting documentation being complete and meeting the requirements of the California Solar Permitting Guidebook checklist, the Building Official shall administratively approve the application and issue all required permits or authorizations.
B. Review of the application shall be limited to the Building Official's review of whether the application meets local, State, and Federal health and safety requirements.
C. Such approval does not authorize an applicant to connect the small residential rooftop energy system to the local utility provider's electricity grid. The applicant is responsible for obtaining such approval or permission from the local utility provider.
D. The City shall not condition approval of an application on the approval of an association, as defined in Section 4080 of the Civil Code.

Full Breakdown
Under Union City Municipal Code § 15.78.070, once the Building Official confirms an application for a small residential rooftop solar energy system (10 kW AC or 30 kW thermal or less, on a single or duplex dwelling) is complete under the California Solar Permitting Guidebook checklist, the city administratively approves it and issues all required permits, with review limited to local, state, and federal health-and-safety compliance. Only one inspection is required, done in a timely, consolidated manner. Incomplete applications get a written correction notice rather than denial. The chapter implements Government Code § 65850.5 (Solar Rights Act / AB 2188).
Violations & Fines
The chapter sets no separate solar-specific penalty; installing a system without the required permit is enforced as unpermitted work under Union City's general Building Code infraction and citation provisions.
