Ramsey County, North Dakota has no countywide building-permit program1. It does have real zoning, though: a county ordinance sets lot sizes, setbacks and districts on land outside city limits where the township has not adopted its own zoning or has given that authority to the county, so confirm which government actually governs your parcel before you assume a rule applies23. Lake Region District Health Unit issues site-specific septic permits in Ramsey County under North Dakota's statewide framework45.

Do you need a building permit in Ramsey County, North Dakota?
Ramsey County itself does not run a countywide building-permit program; the county's own planning page assigns planning and zoning, which can include permitting, to individual cities and townships rather than the county13. North Dakota adopted a new statewide building code, made up of the 2024 IBC, IRC, IMC and IFGC editions, effective January 1, 2026, but the state's Division of Community Services does not enforce it -- only a city, township or county that elects to adopt and enforce the code does1213. Whether Ramsey County itself has made that election was not confirmed on an official county page, so ask before you assume no inspection applies to your project13. A building used only for agriculture, farming, ranching or similar production use is exempt from the state code unless it is a place of human habitation or open to the public14.
Who handles zoning and permits in Ramsey County, and how do you reach them?
Ramsey County Planning & Zoning administers the county's zoning ordinance in the townships where it applies; find the department through the county's website15. For most other planning and zoning questions, the county's own page sends landowners to their city or township directly rather than to the county3. For a septic (OSTS) permit, contact the Lake Region District Health Unit's Environmental Health program at 524 4th Ave NE #9, Devils Lake, ND 58301, (701) 662-704016. For a water-well permit above the state threshold, the North Dakota Department of Water Resources can be reached at 701-328-275011.
Does Ramsey County have zoning?
Ramsey County's zoning ordinance applies to land outside city limits in townships that have not adopted their own zoning or that formally relinquished zoning authority to the county2. City limits and a city's exercised extraterritorial area stay outside county zoning unless that city relinquished or transferred its authority to the county, so a buyer has to confirm which government actually controls a given parcel2. Where county zoning does apply, most rural land falls in the AG-P Agricultural Preservation district, which sets a 40-acre minimum lot size for a non-farm home unless the lot is an existing farmstead or one already recorded with the Ramsey County Recorder7. A commercial farm or ranch active in production agriculture can still split off a lot under 40 acres, and the landowner may convey one additional lot to each child for a detached single-family home10. The R-R Rural Residential district instead requires 2.5 acres for a home on septic or 1 acre for a home on public sewer, and the district itself must be created from a 20-acre tract split into at least 4 lots8. R-R setbacks run 100 feet from the road centerline (or 50 feet from the right-of-way or property line, whichever is greater) in front, 50 feet in back, 25 feet on the side with septic or 15 feet with sewer, and an accessory building needs at least 10 feet on the side and rear and 75 feet in front17. The RS-R Rural Suburban Residential district allows a smaller 1-acre lot with septic, or 21,780 square feet with public sewer, but the district itself must be created from at least 10 acres split into at least 10 lots18.
How do septic permits work in Ramsey County?
North Dakota's Department of Environmental Quality sets the statewide rules for onsite wastewater licensing, permitting and inspections, while local public health units issue site-specific installation permits4. In Ramsey County, Lake Region District Health Unit licenses and permits every new onsite sewage treatment system and repairs to existing systems516. Before work begins, the installer must hold a state license and secure the local health-unit permit; the state license costs $0, and the installer must follow local codes19. Only about 9% of Ramsey County soils have no severe limitation for a conventional drain field, making the site evaluation an important early step20. County-zoned residential districts also use different minimum lot sizes depending on whether a home uses septic or public sewer8.
Can you live in an RV or tiny home on your land in Ramsey County?
No official Ramsey County or North Dakota source establishes a countywide rule for RV, tiny-home or temporary-camping occupancy on private land; the county's own page instead points to whichever city or township actually zones a given parcel3. North Dakota's 14-night camping limit applies to state-park campsites and cabins, not to camping or RV living on private land, so it does not answer this question21. A manufactured home is a separate case with a real statewide rule: it must be installed by an installer licensed by the Division of Community Services and pass at least one inspection for a single-wide or two for a double-wide before anyone can live in it22. Confirm with your township, city or Ramsey County Planning & Zoning, whichever governs your parcel, before placing an RV or tiny home as a residence15.
Building a home in Ramsey County: the steps, in order
- Determine which government actually zones your parcel -- your city, your township, or Ramsey County -- since the rule that applies depends on that answer3.
- If county zoning applies, identify your district (AG-P, R-R, RS-R or another) and confirm the minimum lot size and setbacks before you plan a site223.
- Contact the Lake Region District Health Unit for the site-specific septic permit, and confirm the installer holds the required North Dakota license before work begins519.
- If you plan a well drawing over 12.5 acre-feet a year, apply for a North Dakota Department of Water Resources permit; smaller uses still must be reported to the Department11.
- Confirm whether Ramsey County, your township, or your city has adopted and enforces the North Dakota State Building Code before you assume no inspection is required13.
- If you are installing a manufactured home, use an installer licensed by the Division of Community Services and schedule the required inspection or inspections22.
What to check before you buy land in Ramsey County
About 34% of Ramsey County is federal land, so confirm a parcel's boundaries and access don't run into public land before you buy24. The county is flat and dry: about 100% of it sits at 15% slope or less, annual precipitation runs about 20 inches, and only around 8% of years bring severe drought252627. Budget for a harder septic system than the surrounding land might suggest: only about 9% of Ramsey County's soils carry no severe limitation for a conventional drain field20. Confirm which government zones the parcel and, if it is county-zoned, which district it falls in, since that decides your minimum lot size before you can build2. Ramsey County's effective property tax rate runs about 0.9%, with a median annual bill near $1,8472829.
Watch-outs
- Whether Ramsey County itself has adopted and enforces the North Dakota State Building Code, and whether it requires a building inspection or certificate of occupancy, was not confirmed on an official county page; ask before you assume no inspection applies13.
- RV, tiny-home, manufactured-home and accessory-dwelling occupancy rules were not confirmed at the county level in Ramsey County; ask whichever government actually zones your parcel -- the county, your township, or your city -- before you place one3.
