Building permits, zoning and land rules in Roscommon County, Michigan

Yes. Before constructing a building or structure in Roscommon County, the owner or the owner's representative must submit a written building-permit application to the appropriate enforcing agency, and a change in use or occupancy also requires a permit⁵. Ordinary repairs are exempt, but that exception does not cover structural changes, changes affecting required exits, certain utility work, or other work affecting health or safety⁵. Roscommon County does not run one countywide building counter: the county directs owners to the building department for the township where the parcel lies^2,6. Michigan's current building code is the 2021 Michigan Building Code, with residential requirements in the Michigan Residential Code¹¹. After permitted work is complete, a new or altered building cannot be used or occupied until the code official issues a Certificate of Occupancy⁹.

Roscommon County directs building-department and permit questions to the applicable township building department⁶. Start with the township named on the parcel record, then ask that township which enforcing agency accepts the building, electrical, plumbing and mechanical applications, since Michigan assigns code enforcement to a local unit, a county agency or the state^2,12. A permit application generally needs construction documents, and the enforcing agency inspects permitted construction as it goes^2,13. We could not confirm one countywide inspection schedule, so ask the assigned enforcing agency which inspections to book and when. Michigan's residential-builder licensing exemption covers an owner building for the owner's own use and occupancy on the owner's property, but it does not remove building-permit, inspection, code or zoning requirements⁸.

Roscommon County does not administer zoning countywide: building and zoning are done through each individual township, so the controlling ordinance and zoning contact depend on the parcel's township². That is not the same as no rules; township ordinances can still set districts, setbacks and accessory-building limits, so do not describe a rural parcel as unrestricted¹. We could not confirm one minimum dwelling size, lot size, setback, lot-coverage limit or building-height limit for the county because those are set township by township. Ask the township zoning office for the parcel's district, permitted uses and setbacks before relying on a listing description². Michigan law lets townships, counties, cities and villages establish zoning districts, but the actual district rules remain local¹⁴. Rules for accessory dwellings, manufactured homes and short-term rentals cannot be answered reliably at the county level for the same reason².

The Central Michigan District Health Department issues on-site sewage permits for Roscommon County, including inside its townships and villages, and the Sanitarian issues the permit³. For a new-build site, the septic permit is required before the building permit; mark or flag the vacant property before the Sanitarian's visit, do not begin construction before permit issuance, and expect to reserve an area for future drainfield replacement³. A private well works the same way: a well permit is required from the health department before the building permit on a new-build site⁴. If you are buying a property with an existing septic system or well and need a building permit, an evaluation of both is required³. Call the CMDHD Roscommon Branch at (989) 366-9166 or visit 200 Grand Ave, Suite A, Prudenville, MI 48651¹⁵. Site evaluation matters here because 0% of mapped county soils are rated as free of severe limitations for a conventional septic drain field¹⁰. Michigan requires sanitary sewage to go to an available public sewer or an approved private sewage-disposal system, so an untreated discharge is not an off-grid alternative^16,17.

We could not confirm a countywide rule allowing or prohibiting RV living, temporary camping or tiny-home occupancy on private land in Roscommon County. Because zoning is set by individual townships, ask the parcel's township about dwelling definitions, temporary occupancy, camping duration and utility requirements before moving a unit onto the land². Michigan requires a campground license when five or more recreational units are placed on one parcel as temporary living quarters, which matters if you plan to host several RVs¹⁸. State guidance on tiny houses says a tiny house is not treated as a recreational unit merely because it is built on wheels, and local zoning, building, electrical and plumbing approvals still apply⁷. Any occupied home with sanitary sewage must connect to an available public sewer or use an approved private sewage-disposal system¹⁶. CMDHD is the office to ask about the septic side; the township is the office to ask about land use and occupancy^2,3.

1. Identify the parcel's township and ask its zoning office whether the proposed home, driveway and accessory uses fit the local district².

1. Contact the township's building department to confirm the enforcing agency, application forms and inspection sequence^6,12.

1. Arrange the CMDHD site review, septic permit and well permit before seeking the building permit; the lot must be marked for the Sanitarian's visit and a replacement drainfield area reserved^3,4.

1. Apply to the Roscommon County Road Commission before constructing, reconstructing or modifying a driveway on a county road¹⁹.

1. Submit the building application and required construction documents to the assigned enforcing agency^2,5.

1. Complete the required inspections and obtain the Certificate of Occupancy before using the new or altered building⁹.

Confirm the township first, because that determines the zoning ordinance and the building office that will answer parcel-specific questions^2,6. Make a septic approval contingency part of the purchase decision: 0% of mapped Roscommon County soils are rated without severe limitations for a conventional drain field, and CMDHD requires septic and well permits before the building permit on a new-build site^3,4,10. If you are splitting off a new parcel of less than one acre without public sewer or water, local health department approval is required before a building permit can be issued²⁰. Verify legal road access and driveway approval, because constructing or modifying a county-road driveway requires a Road Commission permit¹⁹. The land is mostly gentle and wooded: 98.4% is at a slope of 15% or less, while 77.1% is forested¹⁰. For budgeting context, the typical home value is $195,107, the effective property-tax rate is 1%, and the median annual property-tax bill is $1,552¹⁰. Floodplain development on rivers, streams and drains can need a state permit, so ask the township and CMDHD about any parcel near water²¹.
