Washington Fire Watch Requirements

Washington adopts the 2021 International Fire Code (IFC) by reference through WAC 51-54A-003, with Washington-specific additions, deletions, and exceptions (effective March 15, 2024). The state's amendment to IFC Chapter 9, WAC 51-54A-0901, does not replace IFC Section 901.7 — so the adopted IFC text is the starting point for systems that are out of service.

IFC Section 901.7, "Systems out of service," sets the framework: when a required fire protection system is out of service, the fire department and fire code official must be notified, and where the fire code official requires it, the building must be evacuated or an approved fire watch provided until protection is restored. There is no automatic statewide grace period — not four hours, not eight, not ten. Local amendments and administrative rules can add requirements on top of the state code.

For water-based systems, NFPA 25 (2020 edition) — referenced by the 2021 Washington Fire Code — supplies impairment-management requirements in its Chapter 15. The owner or a designated representative must assign an impairment coordinator, and when a system is out of service for more than 10 hours in a 24-hour period, one or more mitigation measures must be arranged: evacuation, an approved fire watch, a temporary water supply, or an approved program addressing ignition sources and fuel. That 10-hour mark is a mitigation trigger, not permission to wait when the local authority requires earlier action.

Under RCW 19.27.110, counties administer and enforce the fire code in unincorporated areas, and fire districts or other political subdivisions may assume all or part of that responsibility through interlocal agreements. Inside cities, the municipal fire department or a regional fire authority typically holds that role.

The practical consequence: the crew that responds to your address is not automatically the office that approves or ends a fire watch. A fire district's response boundary alone does not establish its fire-code enforcement authority. Before an impairment — not during one — identify the municipal or county fire marshal or fire prevention office responsible for your property's address.

At the state level, the State Fire Marshal's Office sits within the Washington State Patrol's Fire Protection Bureau. It has specific inspection authority for licensed childcare, healthcare, and residential-care facilities through state licensing agencies, so those properties may have state involvement in addition to local requirements.

Seattle Administrative Rule 9.04.24 (effective December 10, 2024) shows how specific local notification rules can be:

• An anticipated impairment of eight hours or more must be reported to the Seattle Fire Department.
• A planned impairment meeting that threshold requires notice at least five business days in advance; an emergency impairment requires immediate notice.
• For impairments of any duration, affected tenants and supervisors, the owner or manager, the insurer, and the alarm company must be notified.
• The eight-hour reporting threshold is not an eight-hour exemption from mitigation — a fire watch or other approved mitigation can be required for an impairment of any length.

Other cities set their own thresholds and forms. The directory below links the office responsible in each community we serve.
