Unincorporated Pembina County, North Dakota lists farm dwellings, single-family non-farm dwellings, mobile homes and accessory buildings as permitted uses requiring no county zoning permit1. The county does administer zoning, and a local public health permit is required before onsite wastewater work begins12.

Do you need a building permit in Pembina County, North Dakota?
Pembina County's zoning regulations list farm dwellings, single-family non-farm dwellings, mobile homes, accessory buildings and agricultural buildings as permitted uses requiring no zoning permit1. That answer concerns the county zoning permit; we could not confirm a separate residential construction permit or inspection requirement for unincorporated Pembina County. North Dakota has adopted a statewide building-code framework, but Community Services does not enforce it; enforcement belongs to jurisdictions that elect to administer building codes89. Ask the Planning and Zoning Board which building-code jurisdiction, if any, applies to the parcel before ordering plans or starting work6. Agricultural buildings used for agricultural purposes are also exempt from the state building-code chapter unless used for human habitation or by the public10. A residence on a farm does not fit that state agricultural exemption because it is a place of human habitation10.
Who handles Pembina County building and zoning questions?
The Planning and Zoning Board of Pembina County is the starting point for county zoning questions, and the county regulations assign administration and enforcement to the Planning and Zoning Commission and zoning administrator61. Call the county at 701-265-4231 or visit 301 Dakota Street W. #1, Cavalier, ND 58220, and ask to be connected with the zoning administrator6. Before relying on the no-zoning-permit list, describe the proposed use and ask whether the parcel falls under county, municipal or township zoning jurisdiction1. Conditional uses follow a different path, and development within a floodway or floodplain requires a conditional permit11. We could not confirm a published residential inspection schedule, certificate-of-occupancy rule or owner-builder exemption; ask the zoning administrator which approvals and closeout documents apply to the specific project126.
Does Pembina County have zoning?
Yes. Pembina County's regulations apply outside zoning jurisdiction accepted by municipalities and townships1. The county regulations describe the county as an agricultural district and allow listed uses without a zoning permit, including farm dwellings, agricultural buildings, single-family non-farm dwellings, mobile homes and accessory buildings1. North Dakota law allows county commissioners to regulate the location and use of buildings and land under a comprehensive plan, but that statewide authority does not replace Pembina County's own rules13. We could not confirm a current countywide minimum home size, minimum lot size, lot-coverage limit or general building-height limit. Ask the Planning and Zoning Board for the rules governing the exact parcel, particularly where a municipality or township may have its own jurisdiction6. Do not describe land as unrestricted merely because a listed residential use needs no county zoning permit; septic, floodplain, road-access and any applicable building-code requirements remain separate questions21114.
How do septic permits work in Pembina County?
A permit from the local public health unit is required before work begins on an onsite wastewater system in Pembina County2. The North Dakota Department of Environmental Quality separately licenses onsite wastewater installers, and installers must follow local codes15. Pembina County Public Health provides regional environmental-inspector services and can be reached at (701)265-4248 at 301 Dakota Street West #2, Cavalier, North Dakota 582204. Contact Public Health early enough to arrange the application and site evaluation before fixing the house location. Septic feasibility deserves early attention because only about 2.9% of Pembina County soils are rated without severe limitations for a conventional drain field16. That soil rating does not make a parcel unbuildable, but it makes professional site evaluation and system design especially important16. We could not confirm a recurring inspection requirement or which off-grid sanitation alternatives Public Health will approve; ask the regional environmental inspector before selecting a system4.
Can you live in an RV or tiny home in Pembina County?
We could not confirm a Pembina County rule that allows or prohibits living in an RV on private land, either temporarily during construction or as a long-term residence. North Dakota's limit for camping in state-park facilities does not answer the private-land question17. Ask the Planning and Zoning Board for a parcel-specific answer before moving an RV onto the land or installing utilities6. We also could not confirm a county tiny-home occupancy rule or minimum dwelling size. A tiny home should not be assumed exempt from septic, floodplain or jurisdiction-specific building requirements merely because a single-family dwelling is a permitted county zoning use1211. A new manufactured home follows a separate state installation process requiring a licensed installer and licensed inspector18. The county regulations list a mobile home as a permitted use, but that zoning treatment does not erase the state installation rules for manufactured housing118.
Building a home in Pembina County: the steps, in order
- Ask the Planning and Zoning Board whether the parcel is under county, municipal or township zoning jurisdiction61.
- Describe the proposed residence and confirm that it fits a permitted use requiring no county zoning permit, or obtain the required conditional-use instructions1.
- Have Pembina County Public Health begin the onsite wastewater permit and site-evaluation process before work starts24.
- Ask which building-code authority, inspections and occupancy documents apply because county residential enforcement could not be confirmed96.
- Contact the Emergency Management Office if the site may be in a floodway or floodplain; construction there requires a conditional permit11.
- Confirm who controls the adjoining road and discuss the approach, culvert and access with the Pembina County Highway Department when it is a county road14.
What should you check before buying land in Pembina County?
Start by identifying the zoning jurisdiction because Pembina County's regulations yield to accepted municipal or township zoning authority in those areas1. Check the flood map and contact Emergency Management before planning construction in a floodway or floodplain, where a conditional permit is required11. Evaluate soils and wastewater options early because about 2.9% of county soils avoid severe conventional-drain-field limitations16. Confirm legal access and the road authority; the Highway Department maintains county roads, bridges and culverts, while some rural roads are under other authorities14. For a private well, a state water-appropriation permit is required above 12.5 acre-feet per year, while qualifying domestic and livestock uses below that threshold must still be reported7. For budgeting context, farmland averages about $3,915 per acre, the effective property-tax rate is about 1%, and the median annual property-tax bill is about $1,165192021. The county has about 6 people per square mile, and the nearest city of 100,000 or more is about 134 miles from the county center2223.
Watch-outs
- Pembina County has zoning even though several common rural residential uses are listed as needing no zoning permit1.
- A no-zoning-permit use is not a waiver of septic, floodplain, manufactured-home or any applicable building-code requirements211189.
- Only about 2.9% of county soils are rated without severe limitations for a conventional septic drain field, so investigate wastewater feasibility before fixing a house site16.
- RV occupancy, tiny-home standards and a separate residential building-permit requirement remain unconfirmed; ask the Planning and Zoning Board before relying on any exemption6.
- Floodway or floodplain construction requires a conditional permit and coordination with Pembina County Emergency Management11.
