Possible Exemptions
The report states non-habitable detached accessory buildings are exempt from structural permits at 200 square feet or less and 10 feet or less wall height. Membrane-covered frame structures up to 500 square feet are exempt if at least 3 feet from property lines.
Setbacks
Eugene Code 9.2751 requires 5 foot interior side and rear setbacks. At 8 feet above finished grade, the structure must slope inward at 10 inches vertical for every 12 inches horizontal away from the property line, up to 25 feet. Eaves may encroach up to 2 feet into required setbacks.
Foundation
The report lists site-specific snow through the Oregon Design Criteria Hub, 20 psf minimum roof live load, 98 mph Vult Exposure C, SDC D, and 12 inch minimum footing depth.
Inspections
Electrical, plumbing, mechanical, or habitable use can trigger trade or building permits even when the accessory structure is below the basic structural permit threshold. Permit submittal, plan review, fee calculation, and inspections should be verified with the listed local office or portal.
