Read this before you act on anything below. This is my researched starting point for Aitkin County, MN, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesAitkin County, MN

Zoning & raw-land occupancy
Varies locallyIn unincorporated Aitkin County, land use is regulated by the County's Zoning Ordinance adopted under state enabling law, with the Planning Commission handling hearings, conditional/interim use permits, rezonings, and subdivisions. If your parcel is inside the city limits of Aitkin, Hill City, McGregor, McGrath, Palisade, or Tamarack, the city runs its own zoning instead, so check with that city office. source
Dwellings, tiny homes & RVs
Unclear - verifyThe County requires a land use/zoning permit for new structures, additions, and water-oriented structures, and its ordinance mentions manufactured housing, but I found no official page that says clearly whether a tiny home or RV counts as a permanent dwelling. That looks like a case-by-case call from Aitkin County Planning & Zoning, so I'd confirm with them directly before you build or park anything long-term. source
Building permits & codes
Varies locallyAitkin County itself does not enforce the Minnesota State Building Code on unincorporated land, though it still requires its own land use/zoning permits for construction projects. Inside the City of Aitkin, though, the city does enforce the state Building Code and requires permits for essentially all work, even owner-done work, so where you land within the county matters a lot here. source
Septic & composting toilets
Generally allowedAitkin County requires permits for septic systems under its own SSTS Ordinance, which adopts Minnesota Rules Chapter 7080 as its technical standard, and the county's permit system explicitly recognizes outhouses and portable toilets as an option. Installers also have to notify Environmental Services before covering an installation, so plan your inspection timing around that. source
Greywater reuse
Unclear - verifyI couldn't find an Aitkin County page or ordinance excerpt that treats greywater separately from the general SSTS rules. Your best move is to ask Aitkin County Environmental Services how greywater reuse or disposal fits under their septic ordinance.
Rainwater harvesting
Unclear - verifyNo Aitkin County ordinance or webpage addresses rainwater catchment, whether it's simple barrel collection or a plumbed system. The state's plumbing code authority would likely apply to any plumbed setup, but for a straight answer on outdoor collection you'd want to ask the County or the state Department of Labor and Industry.
Private wells & water rights
Generally allowedWells are sited and staked by the property owner as part of the County's land use/septic permitting process, with setbacks from septic systems handled under the SSTS ordinance, while actual well construction and drilling standards stay under the state's Well Code through the Minnesota Department of Health. Aitkin County also runs its own water testing lab if you want your well checked for coliform bacteria, E. coli, or nitrates. source
Living disconnected from utilities
Unclear - verifyI didn't find any Aitkin County ordinance that requires or forbids disconnecting from the electric grid, or that ties occupancy permits to being hooked up to public utilities. This seems to be handled indirectly through septic and well permitting rather than a direct on-grid mandate, so it's worth confirming with Aitkin County Planning & Zoning if this matters for your plans.
