Building permits, zoning and septic rules in Midland County, Michigan

Yes. Before constructing a building or structure in Midland County, the owner must apply in writing to the appropriate enforcing agency; a change in use or occupancy also requires a building permit¹. Ordinary repairs have a limited exception, but structural, egress, plumbing, electrical, mechanical, public-health, and safety work can fall outside it¹. The City of Midland handles its own building permits, while the Township Code Authority serves participating townships and municipalities³. Michigan's statewide construction-code system includes the Michigan Building Code and separate residential requirements². A qualifying owner-builder may build for personal use and occupancy on the owner's property without residential-builder licensing, but the exemption does not remove building permits, inspections, zoning approval, septic permits, or well permits^5,6,7. Permitted construction is periodically inspected⁹, and a new or altered building cannot be occupied until the code official issues a Certificate of Occupancy⁸.

The Township Code Authority of Midland County, at 220 W. Ellsworth Street in Midland, provides building, electrical, mechanical, and plumbing inspections for Edenville, Geneva, Greendale, Homer, Hope, Jasper, Larkin, Lee, Mills, and Warren townships, the City of Auburn, and the Village of Merrill; it provides only electrical, mechanical, and plumbing coverage for the City of Coleman³. Reach the office at 989-837-6521, Monday through Thursday, 9 a.m. to 3:30 p.m.; it is closed Fridays³. The City of Midland handles its own building permits³. Whichever local office issues the building permit or zoning approval, Midland County Environmental Health remains the countywide office for septic and well permits^5,6.

Zoning across Midland County varies because the city, village, or township governing each parcel administers the local rules⁴. The City of Midland has its own zoning ordinance, while other parcels must be checked against the applicable local ordinance¹⁰. City of Midland minimum lot area also varies by district, so a city figure should not be applied to rural township land¹¹. Approved zoning must accompany a building-permit application when required³. We could not confirm one countywide rule for minimum dwelling size, setbacks, lot coverage, building height, RV occupancy, or tiny-home occupancy; ask the parcel's local zoning official about each point. Septic and well permits do not shift to the local zoning office: Midland County Environmental Health handles them countywide^5,6.

A residential onsite septic system in Midland County requires a county septic permit where municipal sewer service is unavailable, and the listed residential fee is $250⁵. Midland County Department of Public Health Environmental Health handles septic permitting throughout the county, including addresses inside cities or other local zoning jurisdictions⁵. Prospective buyers of raw or vacant land can request a percolation-test evaluation to identify installation limits⁵. Septic and well applications must be printed and submitted to the Department of Public Health because online filing is unavailable⁵. Midland County requires a final septic inspection before the system is covered¹². Countywide soil data rates 0% of soils as free of severe limitations for a conventional drain field, so make the parcel-level evaluation an early purchase contingency¹³.

Michigan treats a tiny house as distinct from a recreational unit even when the tiny house is built on wheels, and a tiny house proposed as resort lodging still needs local zoning, building, electrical, and plumbing approvals¹⁴. We could not confirm a Midland County rule allowing full-time RV occupancy or tiny-home occupancy on private land, so ask the parcel's city, village, or township zoning official before buying or moving a unit onto the site. Michigan's campground sanitation rules require privies at primitive campground sites and a local health department permit, but that campground rule does not authorize residential RV living on a private parcel¹⁵. Household sanitary sewage must go to a municipal sanitary sewer or an onsite septic system¹⁶. Midland County Environmental Health handles the septic permit and requires approval before regulated well construction begins^5,6.

1. Identify the city, village, or township governing the parcel because zoning is administered locally⁴.
2. Ask that local zoning official whether the project is allowed and obtain zoning approval when required³.
3. If public sewer is unavailable, arrange a site evaluation and submit the printed septic-permit application to Midland County Environmental Health⁵.
4. If a regulated well is needed, apply to Midland County Environmental Health and wait for well-permit approval before construction⁶.
5. Submit the building-permit application and construction documents to the correct enforcing agency¹.
6. Obtain required electrical, mechanical, and plumbing permits and schedule inspections^3,9.
7. Have Environmental Health complete the final septic inspection before covering the system¹².
8. Obtain a Certificate of Occupancy before using the completed home⁸.

Confirm the municipality and zoning district before relying on a listing's description of allowed uses⁴. Ask Midland County Environmental Health for a perc-test evaluation before closing: 0% of county soils are rated free of severe limits for a conventional drain field, though only a parcel-level evaluation can determine the workable system^5,13. A regulated new well needs a county well permit before construction, and septic and well applications must be printed and submitted rather than filed online^5,6. Ask the correct building office which building, electrical, mechanical, and plumbing permits apply; the Township Code Authority does not cover every jurisdiction³. A driveway connecting to a state trunkline needs an MDOT driveway permit in addition to applicable local approvals¹⁷. Development affecting a regulated river, stream, or drain floodplain may need an EGLE floodplain permit¹⁸. Midland County's median property-tax bill is about $2,771 a year, with an effective rate near 1.5%¹³.
