Permitting metal buildings in Marion County
Marion County sets residential accessory rules countywide and handles ag exemptions through its Building Inspection Division.
Size & height
- All accessory structures together can cover no more than 25% of the rear yard.
- Height is 9 feet at the lot line, rising a foot for every foot of distance, to a 35-foot maximum. Roof drainage has to stay on the property.
Placement
- Front, street-side and interior side yards follow the same setbacks as the house. In the AR zone, that’s 20 feet in front and 10 feet at the sides.
- Anything within 5 feet of the house counts as attached and follows the house’s rules.
The ag exemption
- The building must be part of the farm business, some of the property must receive farm deferral, and the zone must allow farm use. You submit an application and a complete site plan.
- A declaratory statement is recorded with the County Clerk, and electrical, plumbing, mechanical and septic work still need permits.
In Marion County, height comes from distance. A residential shop starts at 9 feet tall at the property line and gains a foot for every foot you move it in, up to 35 feet. A 16-foot building needs at least 7 feet from the line. We’ll place the building and set its height together.
New dwellings near farm or forest zones carry special 100- and 200-foot setbacks. Contact Marion County Building Inspection at 503-588-5147. See all of Oregon.
