Which inspections does a building in California need?

It depends on the building and local code. Fire extinguishers, sprinklers, alarms and emergency lights follow NFPA standards as adopted locally, and elevators and backflow preventers have their own local authorities. Ask your fire marshal, water utility and insurer.
