The Code Enforcement Section investigates complaints regarding violations of King County Codes (KCC) related to zoning, building, property maintenance, shorelines and critical areas in unincorporated King County as outlined in KCC Title 23.

NOTICE: The information contained in complaints is a public record subject to disclosure under the Washington Public Records Act (RCW42.56) and may be requested and inspected by any person. The identity of a complaining party (complainant) may be withheld from public inspection at the Agency's discretion if the complainant indicates that disclosure will endanger any person's life, physical safety, or property. However, if a court case is filed as a result of this complaint, the complainant's identity may be disclosed regardless of a request that it be withheld.

Property must be in unincorporated King County

If unsure, check jurisdiction and zoning.
