Commercial tenant improvements across California: the Bay Area, Los Angeles, Orange County, San Diego and Sacramento
Who reviews your project, what California plan check requires and how to keep review moving.
Each California city runs its own plan check: LADBS in Los Angeles, the Department of Building Inspection in San Francisco, Development Services in San Diego, and building divisions in every other city. Unincorporated areas are reviewed by the county.
Fire sprinkler and alarm changes go to the fire authority. Food businesses need environmental health approval. Coastal zone exterior work can require coastal development review, and Lake Tahoe projects can need TRPA review.
Inspections follow the work, from rough-ins and seismic bracing to fire and building finals, including Title 24 acceptance test documentation. The city then issues a certificate of occupancy or final sign-off.
