Full Breakdown
SRMC § 12.255.020 amends California Residential Code Section R310.7.2 with San Rafael-specific language: smoke alarms must be tested and maintained in accordance with the manufacturer's instructions, and any smoke alarm that no longer functions must be replaced. Where the alarm being replaced is hardwired and/or interconnected, its replacement must match that same functionality, a homeowner cannot swap a hardwired, interconnected system for a standalone battery unit. A near-identical sentence is separately added to Building Code § 909.2 for non-residential occupancies (SRMC § 12.200.020). This upkeep duty sits alongside the Fire Code's point-of-sale and apartment installation mandates in SRMC § 4.08.120, and applies only inside San Rafael city limits.
Violations & Fines
Failing to maintain or properly replace a required smoke alarm is enforced as a building code violation, subject to correction orders and penalties under SRMC Title 12 and Chapter 1.42.
