What kind of work requires a building permit?
Most new construction, remodeling, and repair work that affect a building or structure will require a permit. The State of Washington under Revised Code of Washington (RCW) 19.27 and Cowlitz County have adopted the International Building, and Residential Codes, International Mechanical Code, Uniform Plumbing Code, and the International Fire Code as minimum construction standards for the state and Cowlitz County. While outlining minimum standards, these codes require permits to be issued, and inspections to be performed in order to verify compliance to the minimum construction standards.

Specialists from Building, Planning, and Environmental Health are available to help you determine what permitting will be required for your project or if you may have an exemption.
