Local Project Overview
Pool Construction · Benton County, Washington
Often exempt under 24 sq ft
In Benton County, a Pool Construction under 24 sq ft generally does not require a building permit. At or above 24 sq ft, a permit is required.
The county's own code formally adopts the 2015 edition of the International Swimming Pool and Spa Code, requiring every swimming pool, spa, hot tub, or related structure constructed, enlarged, altered, repaired, relocated, or added to in the county to conform to that code's provisions. Benton City, a municipality within the county, sets its own fence requirement at 6 feet for any pool with a maximum depth over 24 inches, a taller minimum than the more common 4-foot statewide baseline, applied to prevent uncontrolled access from the street or adjacent properties. Building permits in Benton County are handled under the Benton County Community Development, Building Division (unin building code (IRC Benton County Code, ). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Benton County Building Department.
