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

Michigan requires a written permit application before constructing a building or structure or changing its use or occupancy; ordinary repairs are exempt, but structural, egress, utility and safety work does not count as an ordinary repair¹. The statewide code also exempts certain one-story detached sheds and similar accessory structures no larger than 120 square feet, but an exemption does not override zoning or other law⁷. Alpena County has no county building-code program: the City of Alpena and each township enforce building permits locally, while Maple Ridge Township routes mechanical and plumbing enforcement to the state¹. Michigan has adopted statewide building codes, including separate residential requirements, which local enforcing agencies administer⁸. An owner may build for the owner's own use and occupancy without a residential-builder license, but still needs required permits⁹.

There is no single Alpena County building department because the county has no county code-enforcement program¹. The City of Alpena and Alpena, Green, Long Rapids, Maple Ridge, Ossineke, Sanborn, Wellington and Wilson townships provide local building and electrical enforcement¹. Those same local units handle mechanical and plumbing enforcement except in Maple Ridge Township, where the state handles those trades¹. Start with the city or township containing the parcel and ask which forms, plans, inspections and building permit fees apply. The county's own fee schedule lists an erosion-control permit for residential construction and earth changes at $180 for up to one acre plus $85 for each additional acre, so ask the county which office issues it for your site¹⁰. Construction documents are generally part of the application, subject to stated exceptions¹. Septic permits and well permits do not move to the city or township: District Health Department No. 4 handles them for the whole county through its Alpena branch office^3,11.

Alpena County has a planning commission, and Charter Township of Alpena publishes its own zoning ordinance, map, applications, site-plan review and zoning appeals process^2,12. Zoning approval in Alpena County is local. We could not confirm one current countywide zoning ordinance or a complete set of current local rules for every jurisdiction. Ask the township or City of Alpena that contains the parcel for the applicable district map and ordinance before relying on a listing. The local ordinance determines setbacks, minimum lot or dwelling size, height, lot coverage, accessory dwellings, manufactured homes, RV occupancy and short-term rentals. Michigan's mobile-home-community rules do not establish a right to place or occupy a manufactured home on an individual private parcel¹³.

District Health Department No. 4 has septic jurisdiction throughout Alpena County, including its cities, villages and townships³. DHD4 requires a construction permit before an onsite sewage system is built, repaired or altered³. The permit lasts 2 years, is not transferable, and may be denied where an available public sewer exists or the site cannot meet isolation and replacement-area requirements³. DHD4 must inspect the completed residential system before it is covered or backfilled¹⁴. Only 6.1% of Alpena County soils avoid severe limitations for a conventional drain field, so resolve the site evaluation before committing to a house location¹⁵. New wells and extensive changes to existing wells also require a DHD4 permit, and a new supply cannot be used until approved³.

We could not confirm a countywide rule allowing year-round RV or tiny-home occupancy on private land in Alpena County. Ask the township or City of Alpena zoning authority before buying, parking a unit or moving in because local zoning controls the parcel². Michigan's campground rule requires a license when 5 or more recreational units are used as temporary living quarters, but that threshold does not answer whether one household may live in one RV¹⁶. A licensed temporary campground ordinarily may operate for no more than 2 weeks and cannot exceed 4 weeks even with an approved extension¹⁶. Off-grid occupancy still requires adequate lawful sewage disposal; waste cannot be discharged onto the ground or into surface waters, drains or ditches³.

1. Identify the township or City of Alpena jurisdiction and obtain its zoning district rules and zoning approval requirements².
2. Coordinate the driveway location and address with the Road Commission or MDOT and the Equalization Department; the road agency generally needs an address before issuing the driveway permit, with a coordination exception when the driveway must be marked first^17,18.
3. Secure the DHD4 septic permit and well permit before fixing the house location³.
4. Apply to the city or township for the building permit and trade permits (the county issues neither); Maple Ridge Township sends mechanical and plumbing enforcement to the state¹.
5. Obtain any EGLE approval required for development in a regulated river, stream or drain floodplain¹⁹.
6. Arrange construction inspections and the DHD4 septic inspection before work is concealed or backfilled^14,20.
7. Display the assigned address before final inspection and obtain the certificate of occupancy before using the home^6,17.

Get the applicable city or township zoning map and written confirmation that the intended home, RV, manufactured home or accessory use is allowed². Resolve wastewater early: only 6.1% of Alpena County soils avoid severe limitations for a conventional drain field, and an available public sewer can prevent DHD4 from issuing a septic permit^3,15. Verify that a private well can be permitted and approved before relying on off-grid water³. Check flood mapping because regulated river, stream and drain floodplains can require EGLE approval, and residential floors in the regulated floodplain must sit at least 1 foot above the flood elevation¹⁹. Coordinate legal driveway access and the assigned address before closing¹⁷. Alpena County's effective property-tax rate is about 1.1%, and the median annual bill is about $1,556¹⁵.
