Idaho law requires a smoke detector on a wall in a hallway or space communicating with each bedroom area and the living area. Landlords must verify detectors are installed and working at the start of a rental; tenants must maintain them during the tenancy.
Idaho Code 44-2503 sets the statewide installation rule: a smoke detector (which may be a single-station alarm) must be installed on any wall in a hallway or space communicating with each bedroom area and the living area, with the top of the detector 4 to 12 inches below the ceiling. For rentals, Idaho Code 6-320 requires the landlord to verify detectors are installed and in good working order when the lease begins, and the tenant to maintain them during the rental period. New construction in Ada County follows the adopted Idaho Residential Code, which requires interconnected alarms in each bedroom, outside sleeping areas, and on every level.
Failure to install approved smoke detectors in a landlord-controlled dwelling is a breach of Idaho rental law and can support a tenant habitability claim.
