Wyoming, MI Accessory Structures: Shed & Carport Rules (2026)

Wyoming Zoning Ordinance § 90-311 governs accessory buildings and uses on residential property. Detached accessory buildings, including sheds and garages, must be erected only in the rear yard unless the ordinance allows otherwise, and cannot sit closer than three feet to any side or rear lot line; a detached garage may go in a side yard instead, but only at the same setback the principal house must observe. No accessory building can be built before the main house exists, and a single-family or two-family lot is capped at two accessory buildings total, including garages.

Height is capped at one story or 14 feet for most accessory buildings on single- and two-family lots, rising to 17 feet only for detached buildings of 1,200 square feet or more. Size scales with lot area: a lot up to 22,000 square feet may carry 1,000 total square feet of accessory building area with no single building over 768 square feet; a lot over 22,000 square feet up to one acre gets 1,200 total square feet with no building over 900 square feet; a lot over one acre up to two acres gets 1,600 total square feet with no building over 1,200 square feet; and each additional whole acre beyond that adds 200 square feet, up to a 2,400-square-foot cap with no single building over 1,600 square feet.

The required side or rear setback grows with building size too, from three feet for buildings up to 768 square feet to 20 feet for buildings up to 1,600 square feet, and any pre-manufactured accessory building larger than 120 square feet must match the primary building's exterior and roof character rather than looking like an off-the-shelf kit.
