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

Yes. Oscoda County requires an application before construction of a building or structure, and a permit is also required when the use or occupancy of a structure changes¹. The Michigan Building Code, currently the 2021 edition effective April 9, 2025, controls construction, alteration, repair, demolition, use, location, occupancy and maintenance, while one- and two-family dwelling provisions sit in the Michigan Residential Code^1,9. Ordinary repairs are the narrow exception; work affecting structure, egress, plumbing, electrical, mechanical systems, public health or general safety does not fall within that exception¹. A homeowner who is or will become the occupant of a single-family dwelling may personally install a heating or refrigerating system there only after affirming that in the permit application, obtaining the required permits and passing the required inspection⁸. Submit construction documents with the application unless the building official determines that the project description is enough to establish code compliance¹.

The Oscoda County Building Department handles applications and inspections for building, electrical, plumbing, mechanical and soil-erosion work². Call the department at 989-826-1164 for permit questions². The county's permit materials call for an application, plans showing the proposed work and a site plan for residential construction². Zoning is a separate local approval: where a zoning permit is needed, obtain it from the township office for the parcel rather than from a county zoning desk². Oscoda County-specific permit fees were not confirmed, so ask the Building Department for the current fee before budgeting the project.

Zoning exists in Oscoda County, but administration is at the township level rather than through one countywide zoning office². That means the parcel's township is the place to confirm permitted uses, setbacks, minimum lot or home size, accessory buildings and temporary occupancy before choosing a house site². Michigan law provides a framework for counties, townships, cities and villages to establish zoning districts, but the actual districts and regulations come from the applicable local ordinance¹⁰. The county Building Department states that zoning permits, where needed, are obtained at township offices, so secure that local answer before submitting plans that depend on a particular placement or use².

District Health Department No. 2 is the onsite sewage authority serving Oscoda County, and its rules apply in incorporated and unincorporated areas alike⁴, and property owners must obtain a construction permit before installing or repairing an onsite sewage-disposal system^3,5. The application requires a site plan, required site details and the established fee, and the department may deny it when information is incomplete, a municipal sewer is available or the site requirements cannot be met⁵. A department inspection is required before the system is covered or placed into service⁵. Soil conditions deserve early attention: only about 0.8% of county soils are rated without severe limits for a conventional septic drain field, so make approval and system cost a purchase contingency¹¹. A permit is also required before constructing a private water-supply system or making extensive changes to one⁶. Call the health department at (989) 826-3970 about both approvals¹².

Oscoda County does not publish one countywide answer for living in an RV or tiny home on private land because zoning approval is handled by the applicable township². Ask that township whether the proposed dwelling type, placement and any temporary occupancy during construction are allowed on the specific parcel². Michigan's statewide tiny-house guidance does not create a general right to occupy a tiny house; it calls for local zoning, building, electrical and plumbing permits and final approvals⁷. Any residence with plumbing fixtures or drainage piping must connect to a public sewer where available or to an approved private sewage-disposal system¹³. Sanitary sewage from toilets, sinks, showers, washing machines and dishwashers must go to a municipal sewer or onsite septic system¹⁴.

1. Ask the parcel's township zoning office whether the proposed home, setbacks, size and temporary living arrangements comply with its ordinance².
2. Contact District Health Department No. 2 for septic and private-well site review before fixing the house location^3,6.
3. Prepare the building-permit application and construction documents for the Oscoda County Building Department; the building official may waive drawings only when the application description establishes code compliance¹.
4. Coordinate the related electrical, plumbing and mechanical permits with the same county department².
5. Keep the septic system uncovered until District Health Department No. 2 completes the required final inspection⁵.
6. After permitted work is complete and finaled, obtain the required Certificate of Occupancy before using a new or altered building; the permit holder requests it in writing once permits are finaled and fees are paid¹⁵.

Start with buildability: township zoning, county construction permits, health-department septic approval, well approval and legal access can each affect the usable house site^1,2,5,6. Septic feasibility is the sharpest mapped constraint because only about 0.8% of local soils are rated without severe limits for a conventional drain field¹¹. Oscoda County is heavily wooded, at about 83%, while about 85.3% of the land has a slope of 15% or less; clearing and individual soil conditions will still shape site costs¹¹. Federal land accounts for about 42.9% of the county, so verify parcel boundaries and access rather than assuming adjacent open land is usable¹¹. The effective property-tax rate is about 0.9%, with a median annual bill near $1,182¹¹. County driveway and floodplain-development requirements remain unconfirmed; ask the road authority and Building Department before closing.
