Full Breakdown
Lenexa's Unified Development Code sets the shed rules in Section 4-1-B-24-F-2, part of the Article on accessory uses and structures. Every residential accessory building or structure is limited to 25 feet in height. In the R-1, RP-1 and RP-2 districts, a building of 200 square feet or less in ground floor area and no taller than 10 feet must sit at least 5 feet from rear and side property lines. A taller building must sit back a distance at least equal to its height, though never more than the district's normal yard setback.
Anything over 200 square feet, and every accessory structure that is not a building, follows the yard setbacks of its zoning district. In the AG, RE and RP-E districts, a building of 200 square feet or less and 10 feet or less in height can occupy interior side and rear yards with a 10 foot setback. In R-1, RP-1 and RP-2, accessory buildings belong in the rear yard, and can occupy a side yard if they meet district setbacks and use quality materials. On parcels larger than 1 acre the Community Development Director can allow a building in the front yard, behind the required front and side setback lines.
Total floor area is capped three ways. Any single accessory building cannot exceed the ground floor area of the house including attached garages, except bonafide agricultural structures. Lots under 1 acre are capped at 250 square feet per 3,000 square feet of lot area up to 1,500 square feet, and lots of at least 1 acre but under 2 acres are capped at 2,000 square feet. Lots of 5 acres or more have no cap if setback and open space rules are met. Buildings over 200 square feet need quality materials compatible with the house. Temporary portable storage containers cannot serve as permanent accessory structures. The section quoted here does not address building permits.
Violations & Fines
Section 4-1-B-24-F-2 carries no penalty of its own. Section 1-1-C-3 of the Lenexa City Code sets the fallback punishment for any offense the Code declares without a specific one: a fine of not more than $2,500, imprisonment for not more than one year, or both, and City licenses and permits held by the offender can be revoked. The Community Development Department administers the zoning standards.
