Building permits in Tustin, CA
Tustin (Orange County) follows California's statewide codes, but runs its own permit intake, forms, fees, and review timelines through its building department. Here's the general picture for the trades — and where to confirm the specifics.
Tustin's Building Division (Community Development) takes permit applications, plans, and inspection requests online through the Citizen Self Service (CSS) Portal, with City Hall services such as hard-copy plan submittals by appointment. Inspection requests received by 3:00 p.m. are performed the following workday, and minor projects can get a one-hour plan check by appointment. Tustin City Code Sec. 8100 adopts the 2025 California Building Standards Code with local amendments (Ordinance No. 1569, adopted November 18, 2025), and the FY 2026-2027 Comprehensive Fee Schedule took effect April 1, 2026.
