Redlands, CA Fire Regulations: Smoke Detectors (2026)

The City of Redlands does not maintain its own stand-alone smoke-detector ordinance; smoke and carbon monoxide (CO) alarm requirements are set by California state law and the model codes the City has adopted (including the 2022 California Fire Code in City Code Chapter 15.20 and the California Residential/Building Codes). Under California Health & Safety Code Section 13113.7, smoke alarms must be installed in every dwelling unit intended for human occupancy, including single-family homes, apartments, and other residences. Section 17926 requires carbon monoxide alarms in dwelling units that have fossil-fuel-burning appliances, fireplaces, or an attached garage. State standards require smoke alarms in each sleeping room, outside each separate sleeping area (in the immediate vicinity of bedrooms), and on every level of the home, including basements. For existing single-family homes, the seller must provide written certification of smoke-alarm compliance at the point of sale (HSC 13113.8). Landlords are responsible for installing and maintaining required alarms in rental units, and tenants must notify the owner of any inoperable alarm. Alarms should be tested regularly and replaced per the manufacturer's recommendations (typically every 10 years).
