What building code does Oakland, CA use?
Oakland, CA currently enforces the 2025 California Building Code (Title 24, Part 2; based on 2024 IBC). Oakland enforces the state-adopted code. Oakland's 2025 ordinance repealed the 2022 Oakland Amendments (Ord. No. 13717 C.M.S.) and enacted 2025 Oakland Amendments into OMC Chapter 15.04 (sea-level rise, seismic, and fire-risk provisions), adopted early to meet AB 130's 2025-09-30 local-amendment deadline, which also extends the 2025 code cycle to 2031-01-01; fire-code local amendments live outside Ch. 15.04 and were not verified, so fire is listed as the unamended state code.
