Dublin, CA Fire Regulations: Smoke Detectors (2026)

Dublin follows California's statewide smoke and carbon monoxide alarm requirements; the city has adopted the current California Building, Residential, and Fire Codes (Dublin Municipal Code chapters 7.32, 7.34, and 5.08). California Health & Safety Code Section 13113.7 requires working smoke alarms in every dwelling unit. Under the building code, smoke alarms must be installed inside each bedroom, outside each separate sleeping area in the immediate vicinity of bedrooms, and on each level of the dwelling, including basements. Battery-only smoke alarms installed on or after July 1, 2014, must contain a hush feature and a sealed, non-replaceable battery rated to last at least 10 years. Carbon monoxide alarms are required in dwellings that have fuel-burning appliances, fireplaces, or an attached garage. For rental units, the owner must ensure required alarms are operable at the start of each new tenancy, and tenants must notify the owner of any inoperable alarm. The City of Dublin's fire-prevention guidance recommends testing smoke detectors at a minimum every six months. These requirements are typically verified at the time of construction, remodel permits, or property resale. Dublin's fire prevention office can be reached at (925) 833-6606.
