Building permits, township zoning and septic rules in Montcalm County, Michigan

Yes, for most work administered by the Montcalm County Building Department. Permits cover new construction, additions, alterations, changes of use, demolition, mobile-home installation and many garages, sheds, decks, pools and roof projects¹. A residential accessory structure no larger than 200 square feet is one listed exception, and re-siding does not require a building permit¹. The county administers Michigan's construction code only where a township or city does not provide local enforcement, and the City of Greenville issues its own building permits^1,11. Permit fees vary with project size and the work performed¹. Michigan's owner-builder licensing exemption applies when an individual builds on their own property for their own use and occupancy, but it does not waive building permits, inspections, code, zoning or utility requirements⁶.

The Montcalm County Building Department is at 211 W Main Street in Stanton and provides centralized service to all 20 townships¹¹. It handles county building, electrical, plumbing and mechanical permits; inside the City of Greenville, the county office handles electrical, plumbing and mechanical permits while the city handles building permits^1,11. The county applies the state construction code in places without township or city enforcement, so confirm the enforcing agency for the parcel before filing¹¹. The department also runs the Soil Erosion & Sedimentation Control program¹¹. Excavation within 500 feet of a lake, stream, drainage ditch or similar feature may require a soil and sedimentation permit¹.

Montcalm County does not administer a countywide zoning ordinance, but cities, villages and townships may adopt local zoning². Zoned townships enforce their own restrictions and issue their own zoning permits; get parcel-specific rules from the applicable township or municipal zoning administrator⁵. The county therefore sets no zoning-based minimum dwelling size, minimum lot size or setback for unincorporated land, but a local ordinance may set all three². Separate county construction-ordinance setbacks still apply where that ordinance governs: existing platted areas generally require at least 10 feet from road rights-of-way or waterfronts, with different rules and exceptions for accessory structures and corner lots¹⁰.

The Mid-Michigan District Health Department handles on-site sewage permits, repairs and vacant-land evaluations for Montcalm County^3,12. Applications may be submitted in person, by mail or by email, and current fees should be confirmed with the department³. The same department requires permits for new and replacement private residential wells, and the county Building Department lists the well permit among the documents needed for a building permit^4,13. Only about 13.4% of county soils rate free of severe limitations for a conventional drain field, so obtain a parcel-specific evaluation before purchase⁸.

We could not confirm a countywide rule allowing or prohibiting long-term RV occupancy on private land; ask the township or municipal zoning administrator before relying on an RV as housing⁵. A tiny home treated as a building cannot be occupied until the enforcing agency issues a Certificate of Use and Occupancy⁹. Where the Montcalm County Construction Ordinance applies, a tiny home treated as a dwelling must use a permanent frost-free foundation, and a parcel may have no more than two dwellings¹⁰. Local zoning may add use, size or placement restrictions even though Montcalm County has no countywide zoning ordinance².

1. Ask the township or municipal zoning administrator whether local zoning applies and obtain zoning approval if required⁵.
2. Apply to the Mid-Michigan District Health Department for septic and well permits^3,4.
3. Obtain an address through the Montcalm County Equalization Department¹.
4. Get a driveway permit from the Montcalm County Road Commission for a county road or from MDOT for a state highway¹.
5. Ask whether excavation within 500 feet of a lake, stream, drainage ditch or similar feature triggers a soil and sedimentation permit¹.
6. Submit the building application and house plans to the proper enforcing agency; new-house plans require ResCheck or equivalent documentation¹.
7. Complete required inspections and the blower-door test¹.
8. Obtain the Certificate of Occupancy before using a new or altered building⁷.

Confirm local zoning before relying on a planned use, home size or lot size, and check the county construction setbacks separately^5,10. Check septic and well feasibility with the Mid-Michigan District Health Department; only about 13.4% of county soils rate free of severe limitations for a conventional drain field^8,12. Verify legal road access and obtain a driveway permit from the Road Commission on a county road or MDOT on a state highway¹. Ask the Building Department whether excavation needs soil-erosion approval, especially within 500 feet of water or a drainage feature¹. Michigan requires an EGLE permit for certain work in regulated river, stream or drain floodplains, while local standards may also apply¹⁴.
