Off-Grid Living in Cook County, Minnesota

I've been digging into what it actually takes to live off-grid in Cook County, Minnesota, and the short version is: this is one of the more zoning-active counties in the state, so you can't assume the "rural Minnesota, do what you want" reputation applies here. Here's what I found from official sources, and where the trail runs cold.

Zoning and land use. Unlike a lot of Minnesota counties, Cook County actually administers zoning county-wide for unincorporated land, through its Land Services department. That means raw land isn't a blank slate; the county's Land Use Guide Plan and Zoning Ordinance govern what you can do, and subdivided lots created under certain conditions need to go through the platting process under state law before the county will issue a building or septic permit. If you're eyeing a specific parcel, call Land Services before you buy.

Dwellings, tiny homes, RVs. The county requires a Land Use Permit for any structure over 160 square feet, or for any habitable structure no matter the size. That strongly suggests tiny homes count, but I could not find a specific written policy on RVs as full-time residences. Don't guess on this one, call and ask directly.

Building permits. Land Services issues the Land Use Permit locally, but actual contractor licensing (electrical, plumbing, general building trades) is handled at the state level through the Minnesota Department of Labor and Industry. I couldn't confirm which specific building code edition the county has adopted, so ask Land Services directly.

Septic and composting toilets. This is one area with real detail. Minnesota requires every county to run an SSTS (subsurface sewage treatment system) program under state rules, and Cook County has its own septic ordinance. Notably, the ordinance allows a property owner to self-install a privy or a hand-carried water system without a state license, as long as you get a permit and an approved design from a licensed designer, and you notify the department for an inspection before you cover anything up. Septic permits are valid for one year from issuance.

Greywater. The county's environmental health page lists greywater systems as part of its septic program, so it's clearly regulated, but I couldn't pull the actual technical standards. Call Environmental Health for specifics.

Rainwater harvesting. No county ordinance turned up either way. If you're plumbing rainwater indoors, that would fall under the state's plumbing plan review through Labor and Industry, but there's no local supplement I could find.

Wells. Wells are a state matter under Minnesota's Well Code. Generally a licensed contractor must do the work, though an individual can drill their own well on land they own or lease for farming or their own home. The county doesn't permit wells itself but does offer free well water testing.

Grid independence. I found no ordinance requiring or banning a grid disconnect for a habitable dwelling. This would come down to zoning/building enforcement, so confirm directly with Land Services before committing to full off-grid power.
