Washington wrote a trigger, not a rule: the statewide interface chapter is reserved, and RCW 19.27.560 pulls Class 1 roof, wall, deck, and driveway provisions into the building code only when the state's wildfire hazard map is complete. Until then, what applies to your house is the model floor — except in the 1 county with its own sourced application, under local authorities.
The map's completion date is the state's biggest open item, and what we can't tell you yet tracks it alongside the local unknowns.
Rainshadow-to-rainforest planting spans USDA half-zones 6a through 9b: 593 records documented, 141 flagged invasive or noxious. Living here reads both sides of the mountains.
What applies in Washington
Washington’s statewide IWUIC chapter in WAC 51-55 is reserved. RCW 19.27.560 adopts Class 1 roof, wall, deck, and driveway provisions into the state building code only upon completion of DNR’s statewide wildfire hazard map and county base-level risk maps. Counties, cities, and towns may adopt IWUIC locally now. Draft DNR maps are not a construction book. Confirm with the building official.
1 sourced local authority is open below; 1 has a sourced construction application. Local adoption is never implied from silence.

Each page is labeled by the record actually sourced. A fire-access document is not presented as a code adoption.
1 code-application records are normalized below these place nodes.
State distribution, native range, invasive status, hardiness, and fire evidence answer different questions. None is a planting approval. The list itself is on Grow — this page carries the aggregates.
593 plant records documented in the state.
141 carry an invasive or noxious flag applying here. One fire-evidence source names Washington in publication scope.
