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.
Depending on the number and complexity of code compliance cases we’re working on, it may take us longer to respond to new complaints. We prioritize and investigate cases based on their potential to harm public health and safety or the environment. We can only investigate non-priority cases as time allows. Thank you for understanding.
Property must be in unincorporated King County
If unsure, check jurisdiction and zoning.
