Full Breakdown
Kootenai County Code Title 7 (Building Regulations, adopting the IRC with amendments to Section 105.2) exempts from a building permit "One-story detached accessory structures used as tool or storage sheds, playhouses, gazebos, free standing pergolas, and similar uses, provided the floor area does not exceed 200 square feet." Exempt sheds must still conform to the placement (setback) standards in Title 8, keep roof projections within 12 inches of the exterior wall, and stay within a ten-foot eave height.
