Alhambra, CA Fire Regulations: Smoke Detectors (2026)

No Alhambra-specific smoke-detector ordinance was located; instead the city enforces the statewide requirements through its adopted California Building, Residential and Fire Codes (the Fire Code is Chapter 19.02 of the Municipal Code) and through state Health & Safety Code provisions. California Health & Safety Code Section 13113.7 requires smoke alarms in every dwelling unit intended for human occupancy, and the State Building Standards require alarms in each sleeping room, outside each sleeping area, and on every level of a home; alarms must be replaced and upgraded when permits are pulled for additions or alterations. For carbon monoxide, Health & Safety Code Section 17926 requires an approved carbon-monoxide alarm in every existing dwelling unit that has a fossil-fuel-burning appliance (such as a gas furnace or water heater), a fireplace, or an attached garage. In rental housing, the owner is responsible for installing, testing and maintaining smoke and CO alarms and must ensure they are operable at the start of each new tenancy, while tenants must notify the owner of any inoperable alarm. At point of sale, California requires the seller to certify that the property has the required smoke and carbon-monoxide alarms. Because Alhambra has its own Fire Department, the Community Risk Reduction Division handles inspections of multifamily and commercial buildings, where additional fire-alarm and detection requirements in the California Fire Code may apply.
