Land use: zoning and growth management; mining cryptocurrency inside of an area that is zoned for industrial use; allow. Amends 2006 PA 110 (MCL 125.3101 - 125.3702) by adding sec. 515.

HB 4085 allows cryptocurrency mining businesses to operate in industrial zones without needing special land use approvals. It directly affects digital asset mining businesses (defined as groups using over 1 megawatt of energy) operating in areas zoned for industry. The bill prohibits local governments from imposing noise limits beyond general industrial standards or creating unique restrictions for mining businesses compared to data centers in the same zone. This makes mining a "permitted use" under Michigan's zoning law, removing barriers to operation in designated industrial areas.
