Smoke Alarm Tips for Los Angeles
California law requires CO alarms in all single-family homes and most multi-family dwellings — LADBS enforces these requirements during building inspections and real estate transactions
LA County requires smoke detectors in every sleeping room, outside each sleeping area, and on every level — confirm placement requirements with your local fire department
Wildfire risk in the LA Basin makes functional smoke detection especially critical — consider 10-year sealed battery units to eliminate battery maintenance issues
