Building Permits in Kennewick
Building Permits in Kennewick
Building permits in Kennewick are administered by the City of Kennewick Building Safety Division, which provides plan review, code interpretation, permit search, and inspections.
Current codes
Washington's current State Building Code uses the 2021 IBC, IRC, IMC, IFC, UPC and 2021 Washington State Energy Code with state amendments; these editions became effective March 15, 2024. The State Building Code Council says the 2024-code effective date is May 3, 2027. Local amendments may also apply.
Professional-design requirements are project-specific. Kennewick's commercial guidance specifically calls for engineering and/or architectural stamped drawings for buildings over 4,000 square feet, but this should not be read as a universal seal rule for every permit.
Applications and permits
Most commercial alterations, remodels, repairs and improvements require a building permit, and applicants should confirm permit requirements with Building Safety for a particular scope or change of use or occupancy. Kennewick also offers an optional Express Permit program for qualifying projects. The city says Express residential review can be completed in under 48 hours and qualifying commercial review within 72 hours, subject to plan quality and code compliance; these are program-specific targets, not general permit timelines.
Fees
Fees depend on permit type and project characteristics. Commercial plan review requires a plan-review fee at submittal. Express service adds the city-published convenience fee for the applicable Express category. Applicants should use the current city fee information rather than extrapolating a generic percentage to ordinary permits.
Inspections and occupancy
The Building Safety Division performs inspections for permitted work and provides online inspection scheduling. Required inspections depend on the permit and approved plans; final approval and occupancy requirements should be confirmed for the specific project.
