Michigan Zoning Law and Local Control
Michigan local governments — including townships like Cascade — derive their zoning authority from state enabling legislation: the Michigan Zoning Enabling Act (PA 110 of 2006) and the Township Zoning Act. These laws define what municipalities can and cannot regulate, how zoning ordinances must be adopted and amended, and when state law pre-empts local rules.
In recent years, the state legislature has increasingly used pre-emption to override local zoning decisions in areas like short-term rentals, ADUs, and potentially housing density. Each pre-emption expands state authority and limits what Cascade Township (and similar communities) can choose for themselves. The debate over where this line should fall is one of the central tensions in Michigan local government today.
Recent State Pre-emptions of Local Zoning
- ADU mandate (2024): Required all local governments to permit accessory dwelling units in single-family zones, overriding local ordinances that had prohibited them.
- STR limits (2022, contested): PA 57 initially limited local government bans on owner-occupied short-term rentals. Subsequent litigation and legislative revisions have complicated the picture.
- Solar energy: Michigan law limits local government authority to prohibit solar energy systems on residential and commercial properties, though setback and design standards are still permissible.
- Data center zoning bills (proposed): Proposals in the legislature would create a statewide data center overlay district that would allow approvals to bypass local zoning in some circumstances.
The Two Sides
- Fragmented local zoning creates a patchwork that hampers economic development and regional planning
- Local NIMBY-ism blocks housing production and clean energy deployment at scale — state override is sometimes necessary for statewide goals
- Consistent rules make it easier for businesses to invest across multiple jurisdictions
- Michigan communities vary enormously — rural townships, dense suburbs, and cities all have different needs that uniform state rules cannot serve
- Local zoning reflects choices residents make through elected officials about what kind of community they want
- State pre-emption makes it impossible for townships to protect neighborhood character, limit industrial encroachment, or manage growth at a pace consistent with infrastructure capacity
