Building permits, zoning and septic rules across North Dakota

New manufactured homes installed in North Dakota for residential purposes must be installed by an installer licensed by Community Services and inspected by a licensed inspector, with at least 2 inspections on a double-wide and 1 on a single-wide¹². Factory-built modular homes are inspected during manufacture by a third-party inspector approved by Community Services, where the manufacturer produces 2 or more modular structures per year¹³. These are state rules, so they apply on a parcel in a county with no residential building permit as well.

North Dakota has 5 counties with no countywide zoning: Traill County, Ramsey County, Sioux County, Sargent County and Steele County². Only 3 of them also have no residential building permit: Ramsey County, Sioux County and Sargent County⁷. Traill County and Steele County require building permits despite having no countywide zoning⁶. See the no-zoning list and the no-codes, no-zoning list.

County commissioners may zone by district the location and use of buildings and the occupancy of land, following a comprehensive plan¹⁴. Setbacks, minimum dwelling size, lot coverage and building height are set in each local zoning ordinance, not statewide¹⁵. Counties may also regulate subdivision, but not inside city limits, and no county subdivision rule may prevent farming¹⁶. Ask the county planning office which city or township rules reach a parcel.

A septic permit comes from the applicable local public health unit before work begins, and the installer must hold a Department of Environmental Quality license³. Health districts serve 43 counties, and First District Health Unit is the agency named most often⁶. Regular maintenance needs no permit, and the permitting authority must inspect a new installation within 1 business day of the request⁹.

Household wastewater must pass through a septic tank or better treatment before reaching the soil, a new system needs a lot of at least 1 acre unless a variance is granted, and alternative disposal methods are reviewed case by case with no automatic approval⁹. For an off-grid build, ask the local public health unit what it will accept before you buy. DEQ's installer license is free; the local permit fee is separate¹⁷.

North Dakota has a reviewed RV answer for 10 counties: 1 allowed, 2 temporary-only and 7 limited, with 43 counties unanswered⁴. Bowman County permits RV parking in its Agricultural District, which does not establish permanent residence⁴. Dunn County and Billings County give temporary-only answers, with district conditions⁴. Adams County allows a temporary RV residence during construction⁴. The RV-living list is the starting point.

Tiny-home answers exist for 5 counties, all limited, and 48 are unanswered⁶. Wells County, Dunn County and Renville County treat a tiny home as a dwelling only when it meets their zoning definitions; Barnes County and Hettinger County treat trailer-type tiny homes as temporary occupancy⁶. Statewide, we could not confirm a rule for living in a single RV on private land; the state-park camping limits do not answer it¹⁸.

Rolette County leads the Bolthole Index at 68, with no residential building-permit requirement and county zoning^1,6. Cass County follows at 60 with limited permit requirements, and Griggs County scores 58 with none^1,6. Richland County scores 59, though its building-permit answer is unconfirmed⁶.

The median county farmland value is $1,885 per acre, and Billings County is lowest at $1,167⁶. Those are farmland figures, not residential parcel prices. The median county effective property-tax rate is 0.9%, with a median bill of $1,251 a year⁶.

Domestic, livestock and recreational water use below 12.5 acre-feet per year needs no appropriation permit, but the location and capacity of the works must be reported to the Department of Water Resources^11,19. Anyone hired to build, install or repair a well must be licensed; owners may work on their own property without that license¹¹. A DWR construction permit is required for a dike or low-hazard dam able to hold more than 50 acre-feet, which is separate from any local floodplain permit²⁰.

A driveway on state highway right-of-way needs an NDDOT driveway permit before work starts, and altering or relocating it needs the District Engineer's permission²¹.
