Full Breakdown
Smoke alarm requirements in Pierce County come from Washington State law, RCW 43.44.110, enforced locally through the adopted International Fire Code (PCC 17C.60) and the State Building Code. Smoke detection devices must be installed inside all dwelling units, in every sleeping room and hallway. In rentals, the owner or landlord is responsible for installation and must ensure the alarms are operational before a new tenant moves in. Tenants are responsible for ongoing maintenance, including replacing batteries per the manufacturer. Newer construction requires hardwired, interconnected alarms under current building code. Violations carry a fine of up to $200, rising to $5,000 for an owner if a later fire causes property damage, injury, or death after a failure to comply.
Violations & Fines
Non-compliance carries a fine of up to $200; an owner faces a $5,000 fine if a fire later causes damage, injury, or death after failing to provide working alarms.
