Buying Land in Alpena County, Michigan

Zoning: a township-by-township patchwork, not fully mapped here

Alpena County's zoning landscape follows Michigan's township-primary pattern: this research pass confirmed the Charter Township of Alpena (zoning ordinance effective 2020, amended through 2022) and Wilson Township each maintain their own zoning ordinance, administered by their respective township planning commissions. A 2021 University of Michigan CLOSUP fact sheet on the county describes a mix of zoned and unzoned jurisdictions across the county without giving a precise, current, complete list -- so this page does not claim to know the zoning status of every Alpena County township, and neither should a buyer assume one way or the other without checking directly.

Separately, the City of Alpena -- the county's only incorporated city, and the commercial and population center of the region -- runs its own municipal zoning and building department entirely independent of township or county processes. If a parcel sits inside city limits, the city's own zoning code and building department, not any township's, is the relevant authority.

Lake Huron and Thunder Bay: the county's defining natural feature

Alpena County borders Lake Huron directly along a stretch that includes Thunder Bay, home to the Thunder Bay National Marine Sanctuary -- a NOAA-designated underwater preserve protecting one of the largest concentrations of historically significant shipwrecks in the Great Lakes. This designation governs the water and submerged land within the sanctuary's boundaries rather than upland private parcels directly, but it shapes the character and tourism economy of Alpena's Lake Huron shoreline in a way that's worth understanding if you're evaluating waterfront or near-waterfront land in this part of the county.

As with any Great Lakes shoreline county, a parcel directly on Lake Huron in Alpena County should be checked against EGLE's Part 301 (inland lakes and streams doesn't directly apply to a Great Lake itself, but adjoining wetlands often do trigger Part 303 review) and, if relevant, the High Risk Erosion Area program under Part 323 -- this page did not independently confirm whether any specific Alpena County shoreline segment is currently mapped inside a designated HREA.

Short-term rentals: the City of Alpena froze new registrations in 2026

If short-term rental income is part of the appeal of a City of Alpena property, timing matters: the city council approved a one-year moratorium on new short-term rental registrations in March 2026, driven by housing-shortage concerns raised in the 2025 Master Plan survey. The 56 units already registered can keep operating and renewing, but a property without an existing registration cannot get one until the freeze lifts. See our dedicated page on short-term rentals in Alpena for the full picture, including what the city is likely to do next.

Septic and well: District Health Department No. 4

Because Michigan has no statewide septic code, Alpena County's on-site sewage rules come from District Health Department No. 4 (DHD4), which also covers Cheboygan, Montmorency, and Presque Isle Counties under its own sanitary code. DHD4's main office sits in Alpena itself (100 Woods Circle, Suite 200; 989-356-4507 or 989-354-4230), which is a practical convenience compared with counties whose district health department is headquartered elsewhere. Anyone installing a sewage disposal system in the county must register with DHD4 and obtain a permit, though an individual property owner may install their own system without hiring a licensed contractor -- DHD4 also maintains a public list of registered septic contractors and installers for the area.

Well construction follows the statewide Part 127 minimum standard, with DHD4 administering the local permit -- the same office handling both the septic and well steps for a given Alpena County parcel.
