When you don’t need a Shed permit
A non-habitable accessory building not over 200 square feet (and not over 10 feet average roof height, not encroaching the required 5-foot yard) is exempt from a building permit; a one-story frame-covered accessory building up to 500 square feet kept at least 5 feet from property lines is also exempt, under the 2023 Oregon Residential Specialty Code as enforced by the City of Forest Grove Building Division. A larger or closer structure requires a permit. Zoning setbacks still apply.
