Outdoor Burning - non-agricultural

Brush stacked in a pile and burning with lots of smoke. Ecology regulates all types of outdoor burning except forest burning, which is regulated by the Washington State Department of Natural Resources.

Residential Burning

Residential burning refers to burning household yard waste (such as leaves, grass, brush and other yard trimmings) and burning to clear land of trees, stumps, shrubbery, or other natural vegetation.

Is outdoor burning legal in Washington?

Outdoor burning is banned in all urban growth areas in Washington. If you live outside the boundaries of an urban growth area, it is legal to burn natural vegetation, but you should consider alternatives to burning. Find out what you can do instead of burning.

Garbage burning and burn barrels are illegal everywhere in Washington and have been for decades.
