(2) For all dwelling units intended for human occupancy for which a building permit is issued on or after January 1, 2014, for alterations, repairs, or additions exceeding one thousand dollars ($1,000), the permit issuer shall not sign off on the completion of work until the permittee demonstrates that all smoke alarms required for the dwelling unit are devices approved and listed by the State Fire Marshal pursuant to Section 13114.
(3) However, if any local rule, regulation, or ordinance, adopted prior to January 1, 1987, requires installation in a dwelling unit intended for human occupancy of smoke alarms which receive their power from the electrical system of the building and requires compliance with the local rule, regulation, or ordinance at a date subsequent to the dates specified in this section, the compliance date specified in the rule, regulation, or ordinance shall, but only with respect to the dwelling units specified in this section, take precedence over the date specified in this section.
(4) Unless prohibited by local rules, regulations, or ordinances, a battery-operated smoke alarm, which otherwise met the standards adopted pursuant to Section 13114 for smoke alarms at the time of installation, satisfies the requirements of this section.

Full Breakdown
8, and 13114, and implemented through the California Residential Code and California Building Code. Every single-family dwelling, duplex, condominium, and multifamily residential unit in San Ramon must have operable smoke alarms installed in each of the following locations: inside every sleeping room (bedroom), outside each separate sleeping area in the immediate vicinity of the bedrooms (typically a hallway), and on every level of the dwelling including basements. For new construction, additions, and substantial remodels (generally those requiring a permit and affecting bedrooms or hallways), all smoke alarms must be hardwired to the dwelling's electrical system with battery backup, interconnected so that activation of any one alarm sounds all alarms in the dwelling, and installed per manufacturer specifications and CBC requirements.
Since July 1, 2015, all battery-only smoke alarms sold or installed in California must contain a non-removable, 10-year lithium battery (Senate Bill 745). For existing dwellings at the time of property transfer or substantial renovation, sellers and contractors must bring smoke alarm systems into compliance before occupancy permit issuance. Carbon monoxide alarms are separately required (see CO detectors subcategory). San Ramon Building Division inspections verify smoke alarm installation during final permit sign-off. 7(c). Tenant maintenance responsibilities (battery replacement, cleaning) are set by lease but cannot override the landlord's baseline obligation.
Violations of smoke alarm requirements can result in civil penalties up to $200 per violation and can constitute evidence of negligence in fire-related personal injury lawsuits. Seasonal reminder programs and public education by the San Ramon Valley Fire Protection District encourage residents to test alarms monthly and replace units every 10 years.
