Shed Installation Permits in Gresham

Local Rule

City of Gresham Building Permits and Inspections; Gresham residential permit standards

Gresham does not require a permit for a non-habitable one-story detached accessory structure provided the floor area does not exceed 200 square feet and the wall height, measured from the finished floor level to the top of the top plate, does not exceed 10 feet. Building, demolishing, or moving a carport, garage, or shed larger than 200 square feet requires a permit. This exemption applies only to single-family home improvement projects that don't encroach over a drain system, public utility easement, or into required property-line setbacks; the project must still comply with all applicable construction and zoning codes.

How This Compares to Multnomah County

Gresham's own rule is shown above (No permit under 200 sqft). Here is the separate rule that applies at the county level, for context:

Multnomah County / Oregon Building Codes Division

Oregon's statewide ORSC baseline exempts non-habitable, detached, one-story sheds under 200 sq ft and under roughly 10-15 ft in height (measured to average roof height), per the state's own Building Codes Division. Distinctively, the 200 sq ft exemption is not a fixed number in Multnomah County: it is capped by the property's overall lot-coverage limit. If a house and existing garage already use up the allowable lot coverage percentage, a new shed may be restricted to as little as 150 sq ft to stay in compliance, regardless of whether a permit is purchased.
