Building permits in Mission Viejo, CA
Mission Viejo (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.
Mission Viejo's Building Services division (Community Development) accepts permits online only: as of September 2023, all permits and plans are submitted through the city's Client Self Service portal, which also handles plan revisions, fee payments, status checks, and inspection requests. Inspections are conducted next business day when requested before 4:00 PM the day before. Mission Viejo Municipal Code Sec. 8.02.010, enacted by Ordinance No. 25-356 (adopted September 23, 2025), adopts the 2025 California Building Codes with local amendments, and the Master Fee Schedule lists building fees effective April 1, 2023.
