How permitting works in California
California cities have a mandatory, high-intensity role. State law requires every city to enforce the California Building Standards Code. The city's building department is responsible for highly technical reviews, including seismic safety and strict energy efficiency (Title 24) requirements for all projects within city limits.
Mandatory enforcement by every City and County.
