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

Yes. Unincorporated Schoolcraft County requires a building permit for a new home, issued by the county's Building Code Administration^1,8. A permit is also required when a structure's use or occupancy changes, but not for ordinary repairs⁸. Michigan's 2021 Michigan Building Code took effect April 9, 2025, but residential requirements sit in the Michigan Residential Code, and the state's official page still lists the 2015 edition as current while a court order stays the update⁹.

A building permit cannot be issued until an approved zoning application is on file, a rule that also applies before a new septic system can be installed¹⁰. Michigan's residential-builder licensing law exempts a property owner building on their own property for their own occupancy, so you can pull your own permit instead of hiring a licensed builder^1,11. Once work is complete, you need a Certificate of Occupancy from the code official before you can use or occupy the building¹².

Inside the City of Manistique and other incorporated places, check with the city before assuming the county office applies; this answer is for unincorporated land. Septic stays with LMAS wherever the parcel sits³.

The Building Code Administration office is in the county courthouse, Room 207, 300 Walnut Street in Manistique; call 906-341-3678 for permits and inspections¹³. Zoning questions, including the zoning permit your building permit needs, go to the Zoning Ordinance Administration in the same building at 906-341-3674². Septic is handled by an entirely separate agency: the LMAS District Health Department's Schoolcraft County office, 300 Walnut St., Room 155, at (906) 341-6951⁴. The county publishes residential building permit fees of $50 per hour for plan review and $75 per inspection¹⁴. Well permits also come from LMAS, not the county, and a well needs a permit before construction begins³.

Yes, in part. Schoolcraft County publishes a Zoning Ordinance and zoning maps, and its Zoning Administrator issues zoning permits and handles variances and conditional uses². Under the Michigan Zoning Enabling Act, county zoning jurisdiction excludes incorporated cities and villages and areas covered by a township zoning ordinance². Inwood Township states that its zoning is administered by the Schoolcraft County Zoning Ordinance Administration, while the City of Manistique has its own ordinance enforced by its City Manager¹⁵. We could not confirm which other townships have their own zoning, so ask the Zoning Administrator who covers a given parcel².

Where the county ordinance applies, an approved zoning application is required before construction, a new septic system, or a building permit¹⁰. The county's site-plan example shows 25-foot front, 7-foot side, and 15-foot rear setbacks for a non-waterfront lot, and a 50-to-100-foot rear setback from the high-water mark in Lakeshore and River 1, 2, 3, or Natural River Plan districts¹⁶. Those are district-specific examples, so have the Zoning Administrator confirm the measurements for the parcel^2,16. Minimum lot size, minimum dwelling size, lot coverage and building height remain unconfirmed².

Septic in Schoolcraft County goes through the LMAS District Health Department, which covers Luce, Mackinac, Alger, and Schoolcraft counties together and has jurisdiction in cities, villages and townships alike, rather than the county government^3,4. The application requires a completed form, payment, and a site evaluation, and zoning approval must already be on file before a septic permit can be issued¹⁷. Fees are itemized by system type: $182 for the site evaluation, $348 for a conventional no-fill system, $395 for a gravity mound or pressure distribution system, $198 for a septic tank or privy, and $650 for an advanced treatment system, plus an extra $26 for any request requiring travel to an island¹⁷. That range matters here: only about 0.5% of Schoolcraft County's soils have no severe limitations for a conventional septic drain field, among the most limited of any county in this research, so budget for the likelihood of one of the pricier alternative systems¹⁸. A septic permit is valid for two years from issuance, and if it lapses you have only 30 days to request a written extension before you'd need to start the process over¹⁷. LMAS requires a site visit that the applicant must schedule after submitting the application, and allows at least two weeks for evaluation and permit issuance¹⁷. Privies are meant for remote sites with no public electrical utilities or plumbing in a livable structure, and may be subject to township ordinances¹⁹. A new residential well needs an LMAS permit and a registered Michigan well driller, or the owner at their primary residence²⁰.

Schoolcraft County requires an RV Registration Form listing the parcel, property address, valid state ID, vehicle registration and plate, placement date, and a removal date approved by the Planning Director⁵. The form does not establish how long an RV may stay on ordinary private land, so ask the Zoning Administrator whether the parcel's district allows the proposed occupancy^2,5. Michigan separately allows qualifying park-model RVs and camping cabins on licensed campsites in licensed campgrounds; those campground rules do not establish a right to occupy either unit on an ordinary private parcel^21,22. A tiny house used as a dwelling needs local zoning, building, electrical, and plumbing approval plus health-department approval for well and septic service²³. Schoolcraft County-specific tiny-home and manufactured-home occupancy rules remain unconfirmed, so take the unit specifications and site plan to the Zoning Administrator before buying or placing one². Short-term vacation renting is allowed in all county zoning districts once the owner has a county permit, with required liability insurance of at least $500,000 and an occupancy limit of eight persons age 13 or older per dwelling⁶.

1. Contact the Zoning Ordinance Administration for district, setback, and zoning-permit review; zoning approval must precede building and septic permits^2,10,16.
2. Ask the LMAS District Health Department's Schoolcraft County office for a septic site evaluation and onsite sewage permit^4,17.
3. If dividing or platting land, address Michigan Land Division Act review before treating a proposed lot as buildable^24,25.
4. If acting as contractor for a home on your property that you will occupy, use Michigan's owner-builder licensing exemption¹¹.
5. Submit the building permit application to the county Building Code office after zoning approval^1,13.
6. Obtain any required soil-erosion or public-road right-of-way permit before site or driveway work^10,26.
7. Complete required inspections and obtain a Certificate of Occupancy before moving in^12,27.

Get a septic site evaluation before committing: only about 0.5% of Schoolcraft County soils lack severe limits for a conventional drain field, so an alternative system may be needed¹⁸. Confirm legal access, zoning-district boundaries, and whether the parcel was lawfully divided; Michigan regulates subdivision plats under the Land Division Act, with added EGLE review when a proposed subdivision touches specified waters or floodplain^2,24,25. About 29.5% of Schoolcraft County is federal land, making boundary and access review especially useful¹⁸. If the parcel occupies the regulated floodplain of a qualifying watercourse, an EGLE permit can apply and new residential construction is prohibited in the floodway⁷. Michigan Right to Farm protection is conditional on following applicable GAAMPs and is nuisance protection, not a blanket exemption from zoning, building, environmental, or permit rules²⁸. The effective property-tax rate is about 1.1%, and the median annual bill is about $1,348¹⁸.
