Overland Park, KS Accessory Structures: Shed & Carport Rules (2026)

070(A) bars detached accessory buildings, including tool sheds and storage buildings, from any required front or side yard setback area. They may only go in the rear yard, and even there a shed cannot come closer than 3 feet to an interior property line or 20 feet from a street right-of-way line, and cannot sit in front of the platted building setback line. The rear yard coverage of all detached accessory buildings combined cannot exceed 30% of the total rear yard setback area, and no residence may have more than 2 detached accessory buildings on the lot at once.

2), a one-story detached accessory structure used as a tool or storage shed, playhouse or similar use does not need a building permit if its floor area is 200 square feet (18 m2) or less. Anything larger, or any accessory structure that is not a simple tool/storage shed, needs a permit through the Planning and Development Services Department before construction. 070(A) setback, coverage and count limits, and exemptions from permitting are not authorization to violate any other code or ordinance provision. Homeowners planning a larger shed, a second outbuilding, or a shed within 20 feet of the street should check placement against the recorded plat's building setback lines before pouring a foundation, since a violation found after construction requires relocation or removal rather than a variance guarantee.
