Summary
Hayward's Building Division must fast-track small residential rooftop solar permits under amended Section 105.3.1.1, adopted to comply with AB 2188 (Government Code Section 65850.5(a)). Systems on one- or two-family homes up to 10 kW AC or 30 kW thermal qualify for half the normal plan-review time and, staffing permitting, same-day issuance.
The City of Hayward Building Division shall maintain expedited permitting and inspection services for small residential rooftop solar systems as required by AB 2188. This legislation is codified in Subsection (a) of Section 65850.5 of the California Government Code. The following criteria must be met by the applicant to qualify for the expedited permitting process: 1.The installation must be on a one- or two-family dwelling.2.The solar energy system shall not be larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal.3.The submittal documents shall demonstrate compliance with all applicable codes and shall be legible.

Full Breakdown
5(a). To qualify, the installation must be on a one- or two-family dwelling, the solar energy system may not exceed 10 kilowatts AC nameplate rating or 30 kilowatts thermal, and submittal documents must be legible and demonstrate code compliance for wind loads, dead loads, roof structure support, electrical safety and, for thermal systems, plumbing. Qualifying projects get three guaranteed services: a published checklist on the city website flagging any missing minimum-code items with written correction comments; an expedited plan review lasting half the normal review period, with staff making every effort to issue the permit the same day if staffing allows; and a single coordinated inspection between the Building Division and the Fire Prevention Office, so a homeowner is not scheduled for separate visits unless the initial inspection finds noncompliant work.
The Fire Marshal or Building Official retains authority to require additional inspections if the work fails to meet minimum code compliance on the first visit.
Violations & Fines
A rooftop solar system that exceeds the 10 kW AC or 30 kW thermal size cap, or is installed on anything other than a one- or two-family home, does not qualify for the expedited track and is processed under standard plan-review timelines instead. Installing solar without any building permit at all is unpermitted work under amended Section 109.4.1, drawing an investigation fee at least equal to the standard permit fee before any permit will issue.
