Whether a new off-grid home can legally get its own water in Minnesota: the state well and water-rights rules, then the 15 counties where a specific groundwater basin adds a catch — each cited to the state water agency.
Minnesota water rules
Household well
Exempt up to a limit
Regulated-riparian: appropriation permits apply above 10,000 gpd / 1 million gal/yr. Domestic use under those thresholds is exempt; a well-construction notification to the MN Dept. of Health is still required. Household use is far below the cap.
Limit: <=10,000 gpd and <=1,000,000 gal/yr serving <=25 persons
General guidance, not legal advice. Off-grid, building, and land-use rules are often set at the county level and change often. Verify with your county and state before acting. Data reviewed 2026-06-26.
