Milpitas, CA Fire Regulations: Smoke Detectors (2026)

Milpitas Municipal Code Section V-304-5.00, part of the Chapter 304 security bars ordinance, requires approved smoke detectors to be installed and maintained in all units that have bedroom window security bars and in all common-use corridors adjacent to those units. Within each affected unit, the code specifically requires detector placement in each bedroom and in any hallway adjacent to a bedroom, not just a single central detector. The requirement is tied directly to the City's security bar rules: under Section V-304-3.00, security bars on emergency escape windows or doors are a declared public nuisance unless the building both has an approved quick-release mechanism and is equipped with smoke detectors installed in accordance with current building code requirements, and Section V-304-4.00 additionally requires that every quick-release security device system be installed in conjunction with smoke detectors.

Responsibility for upkeep is split by statute: tenants must notify the owner or the owner's agent if a smoke detector becomes inoperable, while owners and tenants together are made responsible for maintaining smoke detector batteries. The rule reflects the City Council's stated findings in Section V-304-1.00 that fixed security bars can trap occupants and delay rescue, so the Council paired the right to keep security bars with a working early-warning system as a condition of keeping them lawfully installed.
