Brentwood Solar Permit Guide
Pacific Gas & Electric (PG&E) territory · Contra Costa County
Overview
GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.
Permit timeline
Same-day review for eligible expedited-permit projects
No verified standard-path permit timeline is available.
The City's own SolarAPP Submittals page states 'Only projects that conform to this list are eligible to use the automated SolarAPP+ portal for instant permitting,' and that 'Once your application is submitted and fees are paid, your permit will be issued' — directly re-verified this session, superseding an earlier, weaker search-engine-derived 3-day estimate that could not be independently confirmed at the time.

California SGIP - current category and budget check required
