Building permits, zoning and land rules in Barnes County, North Dakota

In Barnes County's unincorporated planning area, construction, reconstruction, additions or relocation of a building larger than 150 square feet requires a permit before work or excavation starts; the rule includes mobile homes and farm structures such as grain and hopper bins¹. Like-size replacement of roofs, siding, windows or decks does not require a permit, and farm-use structures are exempt from the building-permit fee¹. The Planning & Zoning Administrator prepares building and Development Code permits⁶. Permitted work cannot move beyond an inspection stage without the building official's approval⁸. Barnes County follows the North Dakota Building Code with county amendments to the latest International Code¹. Barnes County exempts qualifying agricultural uses from most zoning regulations, but building permits, road setbacks, new septic permits and inspections, and floodplain rules still apply¹. Inside Valley City, the city handles building permits under its own construction rules². Septic permits in Valley City still come from the local public-health unit, City-County Health District, while ND DEQ licenses installers^9,10.

Barnes County Planning & Zoning is the first stop for a project on county-administered land because the Planning & Zoning Administrator prepares building and Development Code permits⁶. Call 701-845-8188 or visit 230 4th St NW, Valley City, ND 58072⁶. A building application must describe the building type and materials, the portions of the lot occupied by principal and accessory buildings, and the building cost; property corners or lines must be located before new construction¹. County resolutions and schedules control building-permit charges, applicants may owe processing costs, and building permits generally are not issued until applicable costs are paid¹. Under the county's building-permit fee schedule, structures over 150 square feet but under $5,000 in value are charged $25, and farm-use structures are listed at no charge though they still need a permit¹¹. Septic permits are a separate purchase from the City-County Health District, not from Planning & Zoning^4,10. Before applying, identify the exact parcel because a city, its extraterritorial area or a township with its own zoning authority may administer it instead¹. Ask Planning & Zoning for the current conditional-use or variance charge: published application fees and Development Code filing provisions differ, and processing costs may be added^1,6,12.

Barnes County zoning applies in the county's unincorporated planning area, except within the civil and extraterritorial zoning boundaries of 5 organized cities and townships that elected their own authority¹. Those excluded places retain their own zoning authority, so the correct office depends on the parcel rather than its mailing address¹. The county code publishes agricultural, residential, commercial, industrial and recreational districts with different use, lot, setback and height standards⁵. In county-administered agricultural districts, buildings generally must sit at least 200 feet from the center of a maintained road or section line unless a variance allows less¹. Agricultural residential parcels and residential-district single-family lots generally require at least 5 acres; subdivision residential lots require at least 7,500 square feet with public sewer or one acre with onsite sewer¹. Confirm jurisdiction, zoning district, setbacks and lot standards with Barnes County Planning & Zoning before choosing a house site⁶. Valley City sets its own zoning inside city limits and its extraterritorial jurisdiction³. Valley City septic permits remain with the local public-health unit, City-County Health District^9,10.

A septic installer must secure a permit from the local public-health unit before work begins in Barnes County, while the North Dakota Department of Environmental Quality licenses installers⁴. City-County Health District sells Barnes County septic permits at 415 2nd Avenue NE, Ste. 101 in Valley City and can be reached at 701.845.8518¹⁰. New septic systems remain subject to permits and inspections even on agricultural property, and sanitary systems in subdivisions require County Sanitarian review and approval¹. Subdivisions generally need sanitary sewer service to each lot, although onsite sewage may be allowed after individual review; private septic approval requires a lot of at least 1 acre⁵. Private holding tanks require County Sanitarian approval and a pumping contract filed with the Zoning Administrator⁵. About 45.9% of Barnes County soils are rated without severe limitations for a conventional drain field, so make site evaluation part of the purchase decision¹³.

In county-administered unincorporated Barnes County, the code limits temporary occupancy in a recreational vehicle, motor home, travel trailer or park model to 240 days per year and prohibits more than 2 campers per lot unless additional campers receive conditional-use approval⁵. A residentially zoned parcel requires a conditional-use permit before campers are brought onto it, and units must meet applicable setbacks and stay out of the public right-of-way⁵. A tiny home classified under the county's definitions as a park model or other recreational vehicle falls under that same 240-day limit⁵. We could not confirm a separate rule for other tiny homes or a general minimum dwelling-floor-area requirement; ask Barnes County Planning & Zoning how the parcel's district and building code would classify a proposed unit^1,6. Qualifying manufactured homes are allowed as permanent residences in applicable districts when placed on a permanent foundation or basement, with building-permit and zoning compliance still required¹. For new development in the county planning area, approved onsite sewage is required and privies, outhouses and cesspools are prohibited¹.

1. Ask Barnes County Planning & Zoning whether the county, a city or a township controls the parcel, then confirm the district, lot standard and setbacks¹.
2. Locate the property corners or lines and prepare the building details required for the county application¹.
3. Submit the building and Development Code materials through Barnes County Planning & Zoning when the parcel is county-administered^1,6.
4. Arrange the local public-health septic permit before onsite-wastewater work starts; contact City-County Health District^4,10.
5. If a private well will withdraw more than 12.5 acre-feet per year, obtain a state water-appropriation permit; qualifying lower-volume uses still have reporting requirements⁷.
6. Schedule required building inspections and do not cover work or proceed beyond an inspection stage without approval⁸.
7. Before building on a floodplain site, ask the Zoning Administrator about the Floodplain Ordinance and any additional building-application documents¹.

Start with jurisdiction: Barnes County's code does not govern the civil or extraterritorial zoning areas of 5 organized cities and townships that elected their own zoning, so verify who controls the parcel¹. Check the surveyed building envelope against the applicable district setbacks before treating open ground as a homesite¹. If land will be divided, Barnes County regulates subdivision plats; the Planning Commission reviews the preliminary plat and recommends approval, conditions or denial to the County Commission¹. Confirm septic feasibility early because only about 45.9% of county soils are rated without severe limitations for a conventional drain field¹³. Floodplain construction remains subject to the county Floodplain Ordinance and may require extra building-application documents¹. Barnes County averages about 21.7 inches of precipitation annually and experiences severe drought in roughly 9.7% of years, so verify a dependable water plan before closing¹³.
