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

Yes. Michigan requires a written application to the appropriate enforcing agency before construction, and the Missaukee County Building Department is the countywide office^1,2. A building permit is also required when a structure's use or occupancy changes; ordinary repairs are exempt, but structural, egress, plumbing, electrical or mechanical work affecting health or safety does not count as ordinary repair². Michigan currently identifies the 2021 Michigan Building Code for applicable nonresidential work and the 2015 Michigan Residential Code for residential construction^9,10. A qualifying owner may build on their own property for their own use and occupancy without a residential-builder license, but that exemption does not waive building permits, inspections or code requirements⁷. The agricultural exemption confirmed here is narrow: it covers nursery or agricultural shade-cloth structures, not service systems¹¹. A new or altered building cannot be occupied until the code official issues a Certificate of Occupancy¹².

The Missaukee County Building Department issues building and contractor permits, reviews plans, and runs inspections countywide¹. Plan review can take up to 14 business days¹. Inspection requests need 24 hours' notice, and the county lists inspections from Monday through Thursday with none on Friday¹. Footing holes must remain open before concrete; foundation work requires rebar photographs before the pour and an inspection after the vapor barrier is placed but before backfill¹. The Building Official completes the fee schedule during plan review rather than publishing one flat project price, so ask for a project-specific total¹. District Health Department #10, not the Building Department, handles private-well and septic permits^5,6.

Missaukee County's townships have no zoning, while zoning exists in the City of Lake City and the City of McBain¹. Unincorporated Missaukee County therefore has no zoning-based minimum dwelling size, minimum lot size, lot-coverage limit or building-height limit, though building-code, health, septic and land-division requirements still apply¹. Lake Township is the important exception for setbacks: its agricultural and residential districts generally require at least 9 feet at interior side and rear property lines, while street setbacks are subject to a built-frontage exception³. Commercial and industrial districts use separate setbacks³. For land inside Lake City or McBain, ask the applicable city about the parcel's zoning district and standards¹.

District Health Department #10 issues private-well and septic permits in Missaukee County, and a homeowner may install their own septic system under the permit^4,5,6. A health-officer permit is required before constructing, repairing, altering or extending a residential sewage-disposal system, subject to limited waivers for minor work; where public sewer is unavailable, covered construction cannot proceed without the sewage permit⁶. Before covering the system, the owner or contractor must contact the local sanitarian 24 hours ahead for final inspection⁵. The soil survey rates 0% of Missaukee County soils as free of severe limits for a conventional drain field, so get the site evaluation before settling on a house location or budget⁸. Michigan requires plumbing fixtures to connect to public sewer where available or an approved private sewage system otherwise¹³.

Temporary camping in Missaukee County's unincorporated townships is unrestricted as a zoning matter because those townships have no zoning; septic, health, building, deed and state-law restrictions can still apply¹. That does not confirm permission for long-term RV occupancy or a tiny home as a permanent dwelling in the townships, so ask the Missaukee County Building Department and township supervisor before buying for either use¹. Inside Lake City, an RV cannot serve as a temporary dwelling beyond 10 continuous days, 15 days in any 30-day period or 30 days in a calendar year¹⁴. A Lake City dwelling outside a mobile-home park must be at least 18 feet wide throughout its length, be attached to a foundation, and have adequate water and sanitary facilities; those rules limit many tiny-home designs¹⁴. Lake City also permits accessory dwelling units in specified districts with size, design and owner-occupancy conditions¹⁴. McBain's specific RV, tiny-home and accessory-dwelling rules could not be confirmed; ask the city before relying on the township answer¹.

1. Confirm whether the parcel is in a township, Lake City or McBain; the cities have zoning, while Lake Township has its own setback rules^1,3.
2. Get a site evaluation and apply to District Health Department #10 for private-well and septic permits before covered construction begins^5,6.
3. Submit the parcel number, address and building-permit application to the Missaukee County Building Department, allowing up to 14 business days for plan review¹.
4. Obtain an MDOT driveway permit if access connects to a state trunkline highway¹⁵.
5. Obtain the applicable EGLE permit before altering or occupying a regulated floodplain¹⁶.
6. Give 24 hours' notice for inspections, keep footing holes open before concrete, and do not plan on a Friday inspection¹.
7. Request the Certificate of Occupancy after permitted work is complete¹².

Confirm first whether the parcel sits in a township, Lake City or McBain, because local zoning varies even though Missaukee County's unincorporated townships have no zoning¹. The soil survey rates 0% of Missaukee County soils as free of severe limitations for a conventional drain field, making an early site evaluation essential⁸. About 96.7% of land has a slope of 15% or less, and 64.9% is wooded⁸. Near a river, stream or drain, check floodplain maps because an EGLE permit may be required before work in a regulated 100-year floodplain¹⁶. Missaukee County's parcel-split procedure could not be confirmed, although Michigan regulates subdivision plats statewide; ask the local assessor or township before relying on a recent split¹⁷. Typical property tax is about 1%, with a median bill near $1,600 a year⁸.
