Pasco, WA Fire Regulations: Wildfire Zones (2026)

Pasco has not adopted a formal wildland-urban-interface code overlay or a numeric defensible-space ordinance of the kind used in higher-hazard California and forested communities. Wildfire risk in the area is instead addressed through general fire prevention (Pasco Municipal Code Chapter 16.65, adopting the International Fire Code), nuisance-vegetation enforcement, and outdoor-burning restrictions, together with statewide programs. Geographically, Pasco lies in the arid Columbia Basin shrub-steppe of the Tri-Cities, characterized by cheatgrass, sagebrush, and tumbleweeds that cure to flammable fuel in the hot, windy summers. Independent risk models classify Pasco's wildfire likelihood as medium and greater than a majority of U.S. communities, and the surrounding landscape, including the Juniper Dunes area northeast of the city, has seen significant wildland fires that have triggered evacuations and state firefighting resources in Benton and Franklin counties. For official hazard information, the Washington Department of Natural Resources publishes statewide Wildfire Hazard and Risk maps that cover Franklin County and Pasco, and Ecology/DNR issue seasonal fire-danger levels and burn bans. Practically, the main wildfire defenses available to Pasco residents are keeping dry grass, weeds, and tumbleweeds cleared from around structures, following the City's strict outdoor-burning and recreational-fire rules, observing No-Burn Days, and complying with any statewide or county burn ban during high fire danger. Anyone planning construction in grassland-adjacent areas should ask the City and Pasco Fire Department whether current building or fire-code provisions impose ignition-resistant or access requirements.
