Special Use Permits

A general Special Use Permit (SUP) is a permit for the use of King County property in which the County has an ownership interest. Submit your SUP request by completing an application form.

There may be fees required for processing, administration, land use, inspection, and plan review associated with your SUP request. In addition, there may be a requirement to add King County as an additional insured on your insurance policy and/or bonding requirements to reduce King County exposure to liability and damage.

Your SUP application should include the following information:

• Applicant's name, address, phone number, and email
• How you propose to use County property
• Plans showing the location of the proposed use
• The proposed method of installation and construction
• Define, if required, the proposed method of operation and maintenance
• Define all the required permits necessary to perform the work or installation
• Proposed duration of the use

Please email your completed application to RES.Permits@kingcounty.gov. If you have questions about the application process, please call us at 206-477-9350.
