Do I need a permit for shed or accessory structure in Moses Lake?

Permit may be required

It depends. Whether shed or accessory structure needs a permit in Moses Lake comes down to the details of your project.

The state-adopted 2021 IRC exempts one-story detached accessory structures up to 200 square feet from a building permit, but cities and counties may amend these administrative exemptions, so confirm the local rule. A permit exemption does not waive zoning setbacks, critical-area rules, or height limits set by the city or county. Running power to a shed needs an electrical work permit and inspection from L&I or the city that runs its own electrical program.
