Shed Installation · Yamhill County, Oregon
In Yamhill County, whether a Shed Installation needs a permit is set locally, and the county does not publish a single fixed threshold.
McMinnville, the county seat, follows the standard 200-square-foot ORSC building-permit exemption, but its own municipal zoning code sets a second, lower structural threshold entirely independent of that building-permit line: an accessory structure in the rear or interior side yard is limited to just 100 square feet and 10 feet in height before it must meet the full zone setback requirements, and the city separately enforces a build-order rule barring any accessory structure from being constructed on a lot before a building permit for the primary residence has been issued. Yamhill County itself administers building, electrical, plumbing, and mechanical permits for five specifically named contracted cities, Amity, Carlton, Sheridan, Willamina, and Yamhill, each of which must still separately confirm its own city zoning compliance before the county will issue the permit. The reliable answer comes from Yamhill Co. Planning & Development Dept.. Zoning setbacks apply either way.
