Do you need a building permit in Adams County, North Dakota?
Yes. Adams County requires a building permit, and the county zoning office provides an Adams County building-permit application.12 The county ordinance also exempts land and buildings used for agriculture from most zoning regulations, but road setbacks and floodplain regulations still apply.9 North Dakota separately exempts an agricultural building from the state building-code chapter only when it is not a place of human habitation or used by the public.10
The county materials do not confirm a general inspection schedule, certificate-of-occupancy process, or locally adopted construction code for unincorporated Adams County, so ask Tax Equalization & Zoning what reviews apply to the proposed structure.2 North Dakota’s state code framework took effect in its updated form in 2026, but state Community Services does not enforce that code; enforcement belongs to jurisdictions that elect to administer it.1112
Who issues building permits in Adams County, and how do you reach them?
Adams County Tax Equalization & Zoning is the starting point for county building permits, conditional-use permits, and zoning variances.2 The office is at 602 Adams Avenue Suite 201 in Hettinger and lists (701) 567-2990 and [email protected].2 The county page also links the county building-permit application and county planning-and-zoning request application.2
Before filing, tell the office the parcel location, township, proposed use, building type, and whether the site is near a city boundary so staff can identify the correct zoning authority.3 Ask the office for the current fee because North Dakota leaves permit and plan-review fees to the applicable governing authority rather than setting one statewide schedule.13 Also ask which inspections and occupancy approvals apply, because a general county inspection schedule and certificate-of-occupancy rule could not be confirmed.2
Does Adams County have zoning?
Adams County has zoning for covered unincorporated land, but the ordinance excludes townships that have not relinquished zoning power to the county and certain areas tied to city extraterritorial zoning.3 The ordinance establishes Agricultural, Residential, Recreation, Commercial, Industrial, and Flood Plain districts, and the zoning map is kept in the County Auditor’s office.14 Confirm the parcel’s district and governing authority with Tax Equalization & Zoning before treating a rural address as county-zoned.2
In the residential district, a single-family dwelling lot generally must contain 1.5 acres and measure 150 feet wide, with exceptions for specified subdivisions and a requirement to meet state onsite-sewage standards.7 Buildings must generally sit 150 feet from section lines and county-road centerlines and 250 feet from a state-highway centerline.15 Accessory buildings are limited to 35 feet in height, must be smaller than the principal building, and must stand at least 25 feet from every lot line.16
How do septic permits work in Adams County?
Adams County is served by the Southwestern District Health Unit, and North Dakota requires a local public health permit before work begins on an onsite wastewater system.54 The health district’s Adams County office is at 609 2nd Ave. North in Hettinger and lists (701)567-2720.17 North Dakota also requires the installer to hold a state license and follow local codes.18
Only 11.2% of county soils are rated without severe limitations for a conventional septic drain field, so make the health-unit site review an early purchase contingency rather than assuming a standard system will work.19 The residential zoning rule also ties qualifying lots to state minimum onsite-sewage-disposal standards.7 A general individual-system inspection requirement could not be confirmed, so ask the health unit about the application, site evaluation, inspections, installer documents, and final approval for the specific parcel.17
Can you live in an RV or tiny home on land in Adams County?
In the county residential district, an RV or mobile home may be used temporarily as a residence while a home is being built, but that use is conditional and occupancy may not continue longer than 1 year.6 That provision does not establish year-round RV living on otherwise vacant land, so ask Tax Equalization & Zoning for a written determination before relying on an RV as the primary residence.2
No county provision specifically addressing tiny-home occupancy or a minimum dwelling floor area could be confirmed.2 A tiny home still needs parcel-specific review for the building permit, zoning district, lot dimensions, setbacks, wastewater approval, and the legal classification of the unit.1147154 A new manufactured home installed for residential use in North Dakota must use a state-licensed installer and receive inspection by a state-licensed inspector.20
Building a home in Adams County: what are the steps?
- Ask Adams County Tax Equalization & Zoning to confirm which government controls zoning for the parcel, because county coverage has township and city-area exceptions.32
- Confirm the zoning district, allowed residential use, lot size, lot width, and required road and yard setbacks before finalizing a site plan.14715
- Submit the county building-permit application and any needed conditional-use or variance request through Tax Equalization & Zoning.2
- Contact the Southwestern District Health Unit and secure the local public health permit before onsite wastewater work begins.54
- Ask the zoning office which construction inspections and occupancy approvals apply, because those county procedures could not be confirmed.2
- If the dwelling is manufactured, use a licensed installer and obtain the required licensed inspection.20
What should you check before buying land in Adams County?
Start with jurisdiction: determine whether the parcel is governed by county zoning, township zoning, or city extraterritorial zoning.3 Then verify the mapped district, residential use, lot dimensions, setbacks, legal access, floodplain status, and the approvals needed for the intended structure with Tax Equalization & Zoning.147152
Treat wastewater feasibility as a major due-diligence item because only 11.2% of county soils are rated without severe limitations for a conventional drain field.19 For a private well, North Dakota generally requires a water-appropriation permit when annual withdrawal exceeds 12.5 acre-feet, while certain uses below that threshold must still be reported to the Department of Water Resources.8 Adams County’s effective property-tax rate is about 1%, and the median annual property-tax bill is $1,106, but obtain the parcel’s current assessment and tax record before budgeting.2122
Watch-outs
- County zoning does not necessarily control every unincorporated parcel because some townships retain zoning power and some city-adjacent areas may fall under extraterritorial zoning.3
- An RV or mobile home used as a residence during home construction is a conditional use and is limited to 1 year in the residential district.6
- Only 11.2% of Adams County soils are rated without severe limitations for a conventional septic drain field.19
- The county materials do not confirm general building inspections, a certificate-of-occupancy process, or a specific tiny-home occupancy rule; ask Tax Equalization & Zoning before ordering a structure.2
