Off-Grid Living in Carver County, Minnesota

If you're eyeing a piece of land in Carver County for an off-grid setup, the very first thing I'd nail down is whether that parcel sits in one of the county's ten unincorporated townships or inside one of the incorporated cities (Carver, Chanhassen, Chaska, Waconia, Victoria, etc.). That distinction runs through almost every rule below.

Zoning. In the townships, Carver County's Land Management Department handles zoning directly, under authority granted by Minnesota Statutes 394.21-394.37, with the actual rules written into Chapter 152 of the county code. If your land is inside a city, though, that city runs its own separate zoning department under state law (Minn. Stat. §462.357), so you'd deal with, say, Chaska's or Chanhassen's planning office instead of the county. I couldn't find a page confirming how tiny homes or RVs are treated as permanent residences in either case, this is the kind of definitional question I'd want Land Management staff to answer directly by walking through Chapter 152's use tables.

Building permits. In county-zoned areas, you apply through Land Management, and inspections are handled by a contracted firm, Metro West Inspection Services. Your site plan needs to show where the septic, well, and structures sit. Cities like Carver run their own building departments entirely separate from the county. Electrical work statewide goes through a state electrical inspector, not the local building office.

Septic. This is one area where Carver County is clearly hands-on. Environmental Services runs the county's SSTS (subsurface sewage treatment system) program, built on the state's MPCA Chapter 7080 rules but administered locally under the county's own SSTS ordinance. Inspections get triggered at things like property sale or permit application. The county also runs a low-interest loan program to help fix failing systems, worth asking about if you're buying land with an old system. Composting toilets aren't spelled out separately; they'd fall under this same SSTS framework.

Greywater and rainwater. I found no standalone county ordinance for either one. Greywater likely gets folded into the SSTS wastewater design review, and rainwater harvesting isn't addressed at the county level at all, meaning basic barrel collection appears unregulated locally, while any indoor plumbed catchment system would default to the state plumbing code. Confirm specifics with Environmental Services before you build a system around assumptions.

Wells. Private wells are governed statewide by the Minnesota Department of Health well code, but the county still wants well locations shown on your building permit site plan. If you're near a wetland, stream, or other water resource, the county's separate Water Resource Management Ordinance (the "water rules") may also apply to construction near it.

Utility disconnection. I found nothing explicit banning or requiring grid, water, or sewer hookups for a habitable home. This likely gets tested indirectly through occupancy/habitability requirements in the building code, so it's worth a direct call to Land Management before you commit to living fully off-grid.

Bottom line: townships are more predictable if you want county-administered off-grid flexibility, but always verify with the specific office before you buy or build.
