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

0–7 days

The Residential Solar Requirements handout states: 'Flush mounted solar panel installations (less than 10 kilowatts) for single-family homes are reviewed over the counter when submitted on Tuesdays from 9:00 a.m. to 11:30 a.m. as part of Hayward's "Solar Tuesday" program. If not submitted on Tuesday, the application will be taken in and reviewed by the following Tuesday.' This implies same-day (0 days) review for eligible projects submitted during the Tuesday window, or up to about a week's wait if submitted on another day. Non-flush-mounted systems requiring structural calculations are not covered by this over-the-counter timeline.
