Michigan municipalities lack explicit statutory authority to impose impact fees on new residential development. Unlike states with impact fee enabling acts (e.g., Florida's Impact Fee Act, Colorado C.R.S. 29-20-104.5), Michigan has not enacted a general impact fee statute, and Michigan Supreme Court doctrine in Bolt v. City of Lansing, 459 Mich. 152 (1998), draws a strict constitutional line between regulatory fees (permitted) and disguised taxes (prohibited under the Headlee Amendment without voter approval). As a result, Wyoming's typical ADU-related charges are limited to standard zoning and building permit fees plus water/sewer connection fees if separate service is established. Wyoming has not adopted a residential impact fee.

Wyoming FAQ
Does Wyoming charge an impact fee for ADUs?
Wyoming has not adopted a residential impact fee, and Michigan has no general impact fee enabling statute. ADU applicants typically pay only zoning compliance fees, building permit fees under the Michigan Single State Construction Code, and water/sewer tap-in fees if separate service is established. Confirm current fees with the Wyoming Department of Community and Economic Development and Wyoming Public Works.
Can Michigan municipalities charge school impact fees?
No. Michigan has not enacted a general impact fee enabling statute, and the Headlee Amendment (Const. 1963, art. IX, sec. 31) combined with the Michigan Supreme Court's three-part test in Bolt v. City of Lansing, 459 Mich. 152 (1998), prevents municipalities from imposing fees that function as disguised taxes for general revenue. School districts under the Revised School Code (MCL 380.1 et seq.) have no impact-fee authority.
