Blue Springs, MO Accessory Structures: Shed & Carport Rules (2026)

Section 405.060(A)(3), Accessory Use Development And Operational Standards, governs sheds, storage buildings, gazebos and similar structures citywide. A shed cannot be placed inside any required front yard or street side yard setback at all, unlike a fence or non-load-bearing wall, which the code exempts from that ban. On the rear and side lines, accessory structures are freed from the tighter interior setback that applies to the main house, but they still must clear at least two and one-half feet from a side or rear lot line, and a rear yard that faces a street pushes that minimum out to eight feet.

Height is capped at whichever is less: the height of the principal structure or 16 feet, though the code carves out the RE, Residential Estate district, where a shed can reach 35 feet if its side and rear setbacks are increased to at least 25 feet. Coverage is limited too: a detached accessory structure cannot cover more than 10% of the total lot area, and that figure counts toward the same 10% cap the code separately applies to playhouses, patios, cabanas, gazebos and household storage buildings under Section 405.060(A)(1)(g).

That residential accessory-use list also makes clear that a storage building converted from a wheeled trailer, portable storage container or roll-off trash container is unlawful and does not qualify as a residential accessory use at all, closing off a common workaround for adding cheap shed space.
