Summary
Unincorporated Alameda County runs a checklist-based, administrative-only review for small residential rooftop solar systems, with just one consolidated inspection.
An application for a permit to install a small residential rooftop solar energy system shall be processed in accordance with Government Code Section 65850.5. ... For a small residential rooftop solar energy system eligible for expedited review, only one consolidated inspection shall be required, which shall be done in a timely manner.
Full Breakdown
For a small rooftop solar system on a single or duplex home, 10 kW AC or less, or 30 kW thermal, the county processes the building permit under Government Code § 65850.5's streamlined path rather than discretionary review. The building official maintains a checklist; an application meeting it is deemed complete and gets administratively approved unless there's a specific, documented health-or-safety impact. Applications can be submitted electronically with no wet signature required, and approval can't be conditioned on an HOA's sign-off. Once installed, the system gets one consolidated inspection rather than the multiple rounds a typical addition would need. This is the county's own implementing ordinance for unincorporated areas, layered on top of the state's Solar Rights Act framework.
Violations & Fines
A complete application that meets the checklist must be administratively approved absent a written, evidence-based finding of specific adverse impact; the building official cannot condition approval on HOA approval.
