Smoke alarm requirements in unincorporated Riverside County follow California state law (Health & Safety Code 13113.7) and the adopted California Fire/Residential Code (via Ord. 787). Alarms are required in every bedroom, outside each sleeping area, and on every level. Carbon monoxide alarms are required in dwellings with a fuel-burning appliance, fireplace, or attached garage under HSC 13113.8.
Riverside County does not impose a unique smoke-alarm ordinance; it enforces the statewide standard through its adoption of the California Fire Code and California Residential Code (Ordinance 787 adopts the Fire Code; the County Building Code adopts the Residential Code). Under California Health & Safety Code Section 13113.7 and the California Residential Code, approved smoke alarms (listed by the State Fire Marshal) must be installed in each bedroom, in the hallway or area outside each separate sleeping area, and on every story of a dwelling — including basements — regardless of whether that level has a bedroom. Where more than one alarm is required, alarms in new and substantially remodeled construction must be interconnected so activation of one sounds all, and they must be audible in all bedrooms over background noise with intervening doors closed. Battery-only alarms are accepted in existing dwellings if compliant at installation; California also requires that battery-operated alarms sold and installed use a non-replaceable 10-year battery (per the State Fire Marshal listing standards). Carbon monoxide alarms are separately required under HSC 13113.8 in every dwelling unit that has a fossil-fuel-burning appliance, a fireplace, or an attached garage, installed outside each sleeping area and on each level. Alarms must be tested and maintained; for rental property the owner is responsible for installation and maintenance.
Smoke- and CO-alarm requirements are state law enforced locally through code compliance and at point of sale/remodel permitting. California HSC provides for civil penalties for landlords who fail to install required alarms (commonly cited up to $200 per violation after notice under HSC 13113.7/13263). Building permits for additions or alterations to existing dwellings typically trigger a requirement to bring smoke/CO alarms up to current code.
