Unincorporated Sargent County, North Dakota does not run a countywide residential building-permit program, and its townships, not the county, set zoning1. Forman, Gwinner and Milnor are confirmed code-enforcing cities, so building permits inside those cities come from the city2. Septic permits for any address in the county, city or township, come from the local public health unit, with a DEQ-licensed installer3.
Do you need a building permit in Sargent County, North Dakota?
Unincorporated Sargent County does not administer a countywide residential building-permit program.
Unincorporated Sargent County does not administer a countywide residential building-permit program1. A city, county or township that chooses to enforce building codes must use the State Building Code, with local amendments allowed, and the updated state code took effect in 202611. Forman, Gwinner and Milnor appear in the state's code-enforcement directory, so building permits for work inside those cities come from the city2. We could not confirm each township's residential building-permit rule, so rural owners should identify the township and ask its board before construction. Where a building permit is required, construction cannot be covered before inspection approval, and a final inspection is required before occupancy12.
Who issues building permits in Sargent County, and how do you reach them?
Sargent County's department list does not name a county building, zoning or planning office.
Sargent County's department list does not name a county building, zoning or planning office13. For a rural project, find the parcel's township and ask its board about building permits, zoning, setbacks and inspections4. For work in Forman, Gwinner or Milnor, call the city, since each is listed as a code-enforcing jurisdiction2. Septic permits stay with the county's health unit even inside those cities: the Sargent County District Health Unit is at 316 Main Street, Forman, ND 58032, phone 701-724-37253,14. The Sargent County Road Department, 701-724-3090, answers county-road access questions, though we could not confirm a county driveway-permit rule15. General county questions go to the Sargent County Commission, 355 Main Street South, Forman, ND 58032, 701-724-624113.
Does Sargent County have zoning?
The county itself does not appear to zone; its townships do.
The county itself does not appear to zone; its townships do. State records say every township in Sargent County is zoned and has its own zoning restrictions4. State records list zoning materials for Brampton, Dunbar, Forman, Hall, Harlem, Herman, Jackson, Kingston, Rutland, Sargent, Shuman, Vivian and Whitestone Hill townships, and city zoning can reach into an extraterritorial area around a city1. One concrete example: Dunbar Township's zoning amendment sets a 20-acre lot size, a 150-foot setback and no more than 20 non-farm dwellings per 640 acres for non-farm dwellings, except in pre-platted areas16. Do not assume that standard applies elsewhere. We could not confirm setbacks, minimum lot size or minimum dwelling size for the other townships, so ask the township board for its ordinance and map before choosing a house site. Subdivision rules cannot prohibit farming or its normal incidents, but that protection does not waive township zoning, septic or floodplain requirements17.
How do septic permits and well permits work in Sargent County?
North Dakota DEQ licenses onsite wastewater installers, and the installer must secure a septic permit from the local public health unit before work begins.
North Dakota DEQ licenses onsite wastewater installers, and the installer must secure a septic permit from the local public health unit before work begins3. An individual installing a system on their own premises for their own use is exempt from the installer license, but the work must still follow the state rules, and the local septic permit is still required6. Start with the Sargent County District Health Unit, 316 Main Street, Forman, ND 58032, 701-724-372514. State rules require the health unit to conduct a requested septic inspection within one business day of the request18. Only about 12% of Sargent County soils avoid a severe limitation rating for conventional drain fields, so arrange a site evaluation before fixing the house location19. For wells, a state water-appropriation permit is required for domestic use above 12.5 acre-feet per year; below that, no appropriation permit is needed, but the well's location and capacity must be reported to the Department of Water Resources20. Anyone hired to construct, install or repair a well, pump or pitless unit must be licensed7.
Can you live in an RV or tiny home on your land in Sargent County?
We could not confirm a countywide rule on long-term RV living, temporary camping or tiny-home occupancy on private land in Sargent County.
We could not confirm a countywide rule on long-term RV living, temporary camping or tiny-home occupancy on private land in Sargent County. Because townships and cities set zoning, ask the applicable township board or city whether the unit counts as a dwelling, where it may sit, and whether living in it during construction is allowed4. North Dakota licenses recreational-vehicle parks and campgrounds with 3 or more lots, but that rule does not authorize a single RV or isolated camping on private land9,21. Mobile-home parks with 3 or more lots also need a state license, and that park rule does not say where an individual manufactured home may be occupied9. Any RV or tiny home with plumbing still needs a septic permit from the Sargent County District Health Unit3,14.
Building a home in Sargent County: the steps, in order
Identify whether the parcel is inside a city, in a city's extraterritorial area, or under a township, because zoning is set township by township.
- Identify whether the parcel is inside a city, in a city's extraterritorial area, or under a township, because zoning is set township by township4.
- Ask that township or city for its zoning map, setbacks, permitted uses, building-permit rules and inspection process. Forman, Gwinner and Milnor are confirmed code-enforcing cities2.
- If a building permit is required, schedule inspections before covering construction and a final inspection before occupancy12.
- For septic, use a DEQ-licensed installer (or qualify for the own-premises exemption) and get the septic permit from the Sargent County District Health Unit before work begins3,6,14.
- Ask the County Road Department, 701-724-3090, about a driveway from a county road; we could not confirm a county driveway-permit rule15.
- If the site lies in a Special Flood Hazard Area, get the floodplain permit from the local Floodplain Administrator before any work8.
- Check whether the well will exceed the water-appropriation threshold of 12.5 acre-feet per year20.
What should you check before buying land in Sargent County?
Zoning: identify the governing township or city and get its current map and ordinance, since zoning is set locally and not by the county.
Zoning: identify the governing township or city and get its current map and ordinance, since zoning is set locally and not by the county4. Septic: budget for a licensed installer, the health unit's septic permit and a site evaluation, because only about 12% of county soils avoid a severe limitation rating for conventional drain fields3,19. Water: a well drawing more than 12.5 acre-feet per year needs a water-appropriation permit20. Flood: development in a Special Flood Hazard Area needs a local floodplain permit before work begins; ask the Sargent County Commission who serves as administrator8,13. Access: ask the County Road Department about any county-road approach15. Taxes: the effective property-tax rate is about 1.1%, and the median annual bill is about $1,70819.
Watch-outs
- County commissioners may not prohibit farming, ranching or their normal incidents, but that protection is not a blanket exemption from township zoning, septic or floodplain requirements22.
- Forman, Gwinner and Milnor are confirmed code-enforcing cities, but the state directory advises checking current requirements with the local government2.
- We could not confirm a Sargent County subdivision ordinance, or setback and lot-size rules outside Dunbar Township; ask the township or city that governs the parcel rather than assume one standard applies countywide4.
