Ensuring that work on fire protection sprinkler systems is performed by licensed contractors and certified fitters.

HB 2472 requires all contractors and certified fitters working on fire sprinkler systems in Washington to hold state-issued licenses and certificates. Fire code officials can demand to see these credentials during inspections, and failure to provide them results in an immediate stop-work order until compliance is verified. The law also empowers officials to order removal and replacement of improperly installed systems if public safety is at risk. These requirements apply directly to contractors and fitters performing fire sprinkler work across the state.
