The purpose of a permit is to help ensure that your construction project complies with City codes and essential safety standards. This compliance protects you in several important ways:

• Safety: By following the code, your project meets minimum safety standards designed to protect you, your family, and the public.
• Insurance: Property insurers may only cover work that was completed under a valid permit.
• Resale: If you sell your property, a permit demonstrates that the work was done to code, which can increase buyer confidence.
• Liability: In the event of a legal dispute, having a permit shows that the project met code requirements, offering added protection.

Any property owner or authorized agent planning to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure—or to install, alter, or replace any gas, mechanical, or plumbing system regulated by the building code—must first obtain the appropriate permit. Work within environmentally critical areas, shoreline areas, native growth protection areas (such as tracts), and their associated buffers may not be exempt from permit requirements. If your project involves any of these areas, please contact us at permittech@kenmorewa.gov before proceeding.

Important: Even if your project qualifies for a permit exemption, you are not authorized to perform any work that violates City codes, laws, or ordinances. Exemptions do not override code compliance requirements.
