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

Yes. Houghton County requires the permit application to be filed and the permit issued before building, electrical, mechanical or plumbing work begins; starting first adds a 50% fee¹. The 2021 Michigan Building Code governs covered nonresidential work, while the 2015 Michigan Residential Code remains in effect for residential work under a court order¹¹. The applicable enforcing agency requires inspections¹². A homeowner may perform residential work after signing the Homeowner's Affidavit, while a hired contractor must apply and prove licensure¹³. The owner-builder license exception applies when a person builds a residential structure on the person's property for personal use and occupancy, but it does not waive building permits⁷. A qualifying agricultural building needs no building permit: the exemption applies only when agricultural activity occurs on the parcel, the building is used solely for agriculture and it is not used for retail trade; a later change of use requires a new affidavit or compliance with county requirements and applicable codes^2,9. New construction cannot be occupied until final inspections are complete and a Certificate of Occupancy is issued^13,14.

The Houghton County Building Department issues building, electrical, mechanical and plumbing permits for the entire county¹³. The office is on the first floor of the Houghton County Courthouse at 401 E. Houghton Ave., Houghton, MI 49931, and its phone number is 906-482-2260¹. Office hours are Monday through Friday, 8:00 a.m. to 4:30 p.m¹.. The department directs zoning questions to the parcel's municipality because Houghton County has no county-wide zoning¹. The published fee schedule starts at $75 for improvement cost up to $1,000, includes one inspection at that tier, charges plan review at $125 per hour, and makes permits valid for two years¹⁵. Apply before work begins because the county adds 50% of the permit fee when work starts first¹⁵.

Houghton County sewage-producing facilities must connect to an available public sewer; “available” means physically and politically available, with acceptable design and capacity, within 200 feet of the proposed sewage origin³. When the Western Upper Peninsula Health Department (WUPHD) determines no sewer is available, an approved onsite sewage system is required³. WUPHD requires a construction permit before a residential or commercial onsite sewage system is constructed, altered, extended or replaced, and a site-and-soils evaluation comes before permit issuance⁴. A local government cannot issue a building permit for land needing onsite sewage until WUPHD approval is obtained^4,5. Every newly installed permitted onsite system needs a final construction inspection before use or department approval, and new components cannot be covered before inspection or permission to backfill³. Existing systems may need inspection for a sale, home loan, care or food-facility license, remodel or addition, but the published rule does not make inspection universal for every existing home¹⁶. Only 1.6% of county soils are rated without severe limitations for a conventional drain field, so make the evaluation an early purchase contingency rather than assuming a conventional system will fit¹⁰. WUPHD may allow an alternative onsite system when a site fails conventional requirements⁴.

Unincorporated Houghton County has no county land-use zoning restriction on RV occupancy or temporary camping, but municipal zoning, health and wastewater requirements may still apply; ask the parcel’s city, village or township about the proposed stay⁸. Michigan requires an EGLE campground license for 5 or more campsites and/or recreational units; that threshold does not establish permission to occupy a private RV below the threshold¹⁷. A temporary campground with 5 or more recreational units needs a local health department license, with an application at least 14 days before the event; operation is limited to 2 weeks unless extended, never more than 4 weeks, with 30 days between licensing periods at the same location¹⁸. Unincorporated Houghton County has no county zoning restriction on tiny-home occupancy, but municipal and non-zoning rules remain⁸. Michigan’s resort guidance does not automatically treat a tiny house on wheels as a campground recreational unit; health, zoning and construction approvals still apply¹⁹. WUPHD may permit a privy, but not as a septic substitute for a dwelling with pressurized plumbing or water-carried sewage³.

1. Identify the parcel's city, village or township and obtain its current zoning answer before designing the house²⁰.
2. Ask WUPHD for a site-and-soils evaluation; only 1.6% of county soils are rated without severe limits for a conventional drain field¹⁰.
3. Confirm sewer availability with WUPHD; connect to an available sewer or obtain approval for onsite sewage before the building permit^3,4.
4. Apply to the Houghton County Building Department for building, electrical, plumbing and mechanical permits before starting work^1,13.
5. Obtain a Road Commission driveway permit for a new or changed entrance in a county-road right-of-way, or an MDOT permit for driveway work in a state-highway right-of-way^21,22.
6. Sign the Homeowner's Affidavit if doing the residential work yourself, or have the licensed contractor apply and accept responsibility¹³.
7. Complete the required building and septic inspections, then obtain the Certificate of Occupancy before moving in^3,13,14.

Houghton County is 86.4% wooded and 25% federal land, while the nearest city of 100,000 or more is about 168 miles from the county center¹⁰. Houghton County has no county-wide zoning, but local city, village or township zoning varies²⁰. A new, changed or reconstructed driveway in a county-road right-of-way requires a Houghton County Road Commission permit; access in a state-highway right-of-way instead requires an MDOT permit^21,22. The county-road right-of-way permit covers only the described work; changes require an additional permit or amendment, and other local permissions remain separate²¹. Michigan’s Land Division Act governs subdivision plats and land divisions, with state final plat review, but parcel-specific local zoning, access, health, septic and floodplain requirements still need separate review²³. Septic suitability deserves an early contingency because only 1.6% of county soils are rated without severe limits for a conventional drain field¹⁰. Check floodplain status before choosing a building pad because Michigan requires a permit for covered alteration or occupation of a regulated river, stream or drain floodplain²⁴. Houghton County's effective property-tax rate is about 1.3%, with a median annual bill near $1,780¹⁰.
