Deck Construction · Yakima County, Washington
In Yakima County, a Deck Construction under 30 sq ft generally does not require a building permit. At or above 30 sq ft, a permit is required.
The county's own current exempt-work list confirms decks, sidewalks, ramps, and driveways with no roof cover and 30 inches or less above adjacent grade are exempt from a building permit, with pergolas (rafters only, no solid roof) also permitted within that exemption. Anything with a roof cover, or exceeding 30 inches, requires a permit. Building permits in Yakima County are handled under the Yakima County Building Division (unincorporated areas) building code (IRC Yakima County Exempt). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Yakima County Building Permits.
