How development impact fees work in Washington

Washington impact fees are authorized under the Growth Management Act (RCW 82.02). Notably, Washington school districts commonly levy large school impact fees that the city or county collects — these can be the biggest single component.

Separate from impact fees, water and sewer utilities charge 'general facility charges' (GFCs) for connection, and SEPA environmental mitigation may apply to larger projects.
