Pleasanton, CA Fire Regulations: Smoke Detectors (2026)

Pleasanton adopts the California Residential Code (PMC Chapter 20.10) and California Building Code (PMC Chapter 20.08), which incorporate the statewide smoke-alarm and carbon-monoxide-alarm placement standards for new construction, additions, and certain alterations — generally requiring alarms in each sleeping room, outside each sleeping area, and on every story. State law layers on top for existing homes. Under California Health and Safety Code Section 13113.7, owner-installed, State Fire Marshal-listed smoke alarms are required in dwelling units intended for human occupancy (one- and two-unit dwellings, apartments, hotels, motels, condominiums, and similar), and owners of rental units must test and maintain alarms and ensure they are operable at the start of each tenancy. Section 13113.8 requires every single-family dwelling sold on or after January 1, 1986 to have operable, State Fire Marshal-approved smoke alarms at point of sale. Carbon monoxide alarms are required by Section 17926 in existing dwelling units that have a fossil-fuel-burning heater or appliance, a fireplace, or an attached garage; alarms must be placed outside each sleeping area and on every level, including basements. The Livermore-Pleasanton Fire Department assists residents with battery-operated smoke detectors and provides home safety information.
