Do you need a building permit in Divide County, North Dakota?
Yes. Divide County requires a building permit whenever a structure is built or moved onto property in the county.1 The county adopted the North Dakota State Building Code and may add requirements for local needs.14
Keep the issued permit posted until the project and all required inspections and approvals are complete.2 Divide County will not issue a certificate of occupancy or allow use of the building until those inspections and approvals are finished.3 Building-permit and plan-review fees are set by the enforcing jurisdiction, so request the current amount before filing; the county's published work-housing charges are specialized fees, not a general residential building-permit schedule.1516 Agricultural buildings are exempt from the state building-code chapter only when they are not used for human habitation or by the public; county zoning and other applicable rules may still apply.17
Who issues building permits in Divide County, North Dakota, and how do you reach them?
Start with Divide County DES/Zoning/911 at the courthouse in Crosby: call (701) 965-6361 or visit 200 N Main St., Crosby, ND 58730.18 The county publishes its building-permit application through the Planning and Zoning forms page.18
Give the office the parcel address because jurisdiction varies: the county ordinance covers unorganized townships, organized townships may retain their own zoning, and incorporated municipalities may have separate rules.46 North Dakota assigns code enforcement to a city, township or county that elects to administer it, and county enforcement applies where a city or township does not.19 We could not confirm an owner-builder exemption from Divide County permit or inspection requirements, so an owner acting as builder should ask DES/Zoning/911 which inspections, licensed trades and documents apply. After issuance, the county permit must stay posted through completion of required inspections and approvals.2
Does Divide County, North Dakota have zoning?
Yes, but the governing authority depends on the parcel. Divide County's ordinance applies throughout unorganized townships; organized townships may keep their own zoning, and incorporated municipalities may have separate rules.46 County-administered land is divided among Agricultural, Commercial, Industrial, Rural Residential and Recreational districts.10 Ask the county planning office to identify the jurisdiction and district before relying on a listing description.18
Homes with septic systems require at least 43,560 square feet, 100 feet of width and 200 feet of depth.20 Coverage limits vary by district.21 Buildings generally may not exceed 40 feet without a variance, with exceptions for agricultural, industrial and institutional structures and specified appurtenances.22 Farmers may establish up to two accessory dwellings for employees directly engaged in agricultural operations, while a Recreational District accessory dwelling requires conditional-use approval.23 We could not confirm a county minimum dwelling floor area, so ask the office about a particular small-home plan.
How do septic permits work in Divide County, North Dakota?
The Upper Missouri District Health Unit permits septic systems in Divide County and licenses installers in its service area.5 A local public-health permit must be secured before an onsite wastewater system is installed, while the installer also needs the state license required by the North Dakota Department of Environmental Quality.2425
Divide County's own ordinance requires the health unit's septic or sewer permit for an application involving a sewage-treatment or septic system; subdivision projects also need percolation tests before a building permit is issued.7 Private water and sewer systems must be inspected by the health unit before final approval and hookup and certified to meet state health standards.26 Call the local office at 701-965-6813 before site work.27 Only 40.2% of county soils rate as free of severe limitations for a conventional drain field, so make wastewater feasibility an early purchase contingency.28 Ask the health unit about inspection and cover-up timing for the proposed system.
Can you live in an RV or tiny home on land in Divide County, North Dakota?
Divide County defines a recreational vehicle for vacation or recreation, not year-round residence.8 An occupied RV in an RV park is limited to 45 days or less, and campground occupancy by a travel trailer or tent may not exceed 45 days in a consecutive six-month period.9 Those limits do not answer occupancy on every private parcel, so ask the planning office whether temporary RV living during construction is allowed in the parcel's district.918
A tiny home built or moved onto property still requires the county building permit and district review.110 We could not confirm a tiny-home-specific occupancy rule or minimum dwelling floor area, so obtain a written answer for the proposed design and use. A new manufactured home installed for residential use in North Dakota must be installed and inspected by state-licensed professionals.29 Accessory dwellings are limited by district and use.23
How do you build a home in Divide County, North Dakota, step by step?
- Give Divide County DES/Zoning/911 the parcel address and confirm the governing jurisdiction, zoning district and allowed use.18610
- Confirm lot size, coverage, height, access and any variance or conditional-use approval before finalizing plans.202122
- For an Agricultural District access point, obtain a permit from the Divide County Road Department or the Township Board for the road being accessed.30
- Apply for the building permit before construction or moving a structure onto the property, and request the current fee and plan-review requirements.115
- Obtain the Upper Missouri District Health Unit septic permit before wastewater work; private water and sewer systems also need health-unit inspection and certification before final hookup.731
- Keep the building permit posted, complete every required inspection and approval, and obtain the certificate of occupancy before using the building.23
What should you check before buying land in Divide County, North Dakota?
Begin by identifying the governing zoning authority, district, buildable area and wastewater feasibility. County rules do not replace retained township zoning or separate municipal authority, and only 40.2% of Divide County soils rate without severe limitations for a conventional septic drain field.628 Ask Planning and Zoning whether the parcel lies in a regulated floodplain and who reviews floodplain development, because we could not confirm a standalone local process.
Confirm legal access and the responsible road authority: Agricultural District access points require a permit from the Divide County Road Department or the Township Board for the road being accessed.30 A proposed access connection involving the state highway system also requires coordination with NDDOT, and work within state highway right-of-way needs an NDDOT driveway permit before it proceeds.32 If land will be divided, the county's sketch-plan and plat process involves county staff, affected township boards, the Planning and Zoning Commission, county commissioners, applicable agencies and the public.33 For a private well, the state Department of Water Resources requires a permit only when the well will draw more than 12.5 acre-feet per year, and a hired person who builds or repairs a well must be a licensed contractor.1213
Watch-outs
- The agricultural building-code exemption does not cover buildings used for habitation or by the public, and county zoning or other rules may still apply.17
- Do not begin septic work with only a building application: a local public-health permit is required before installation.725
- RV-park and campground stays are limited, but private-parcel RV occupancy remains unconfirmed; ask DES/Zoning/911 before planning to live in one.918
- Conventional septic feasibility is not automatic because only 40.2% of Divide County soils rate without severe drain-field limitations.28
