Do you need a building permit in McKenzie County, North Dakota?
In unincorporated McKenzie County within the county ordinance's jurisdiction, a building permit is required before building, structurally altering or moving a structure; nonstructural maintenance is exempt1. County jurisdiction excludes incorporated cities, city extraterritorial areas, townships retaining zoning power, tribal land and federal land11. A permit expires if construction does not begin within one year after issuance11. The written waiver for certain on-site oil and gas processing or storage structures excludes structures designed for regular occupancy and preserves required fire and safety inspections1.
Watford City and Alexander issue their own building permits; septic installation permits remain with the Upper Missouri District Health Unit, and North Dakota DEQ licenses installers121354.
McKenzie County construction must meet the North Dakota State Building Code provisions named in the county ordinance7. Agricultural buildings are exempt from the state building-code chapter only when not used for human habitation or by the public; that exemption does not itself waive county zoning or building permits14.
Who issues building permits in McKenzie County, North Dakota, and how do you reach them?
Start with the McKenzie County Building Department at 1300 12th St. SE, Ste. 214, Watford City, ND 58854; call (701) 444-2420 or email building@co.mckenzie.nd.us15. The McKenzie County Planning and Zoning Department uses the same phone number and is at the McKenzie County Public Works Building, 1300 12th St SE Ste. 214, Watford City, ND 58854; zoning questions can go to pandz@co.mckenzie.nd.us16.
McKenzie County building-permit applications go to the Planning Department under the ordinance; the Building Department is the contact for building permits and inspections115. Ask which application, plans, inspections and fees apply to the exact project. Building, planning and zoning permit fees follow a schedule that the Board of County Commissioners approves and amends from time to time, and application fees are non-refundable17. The fee amounts and online process could not be confirmed, so ask the Building Department.
Does McKenzie County have zoning?
McKenzie County's Land Development Ordinance includes zoning districts, a zoning map, subdivision regulations and district-specific dimensional standards6. County zoning excludes incorporated cities, city extraterritorial areas and townships that retain zoning power2. Watford City sets zoning within the city and its extraterritorial area, while Alexander sets zoning inside its city limits; septic installation permits remain with the Upper Missouri District Health Unit18195.
For workforce-housing developments, McKenzie County requires at least 15 feet between units, plot plans, applicable wastewater and other environmental permits, and a reclamation bond; housing types cannot be mixed within a facility20. That spacing rule applies to workforce housing, so ask Planning and Zoning for the setbacks governing a proposed private home2016. Tiny-home occupancy, accessory dwellings and minimum dwelling floor area could not be confirmed; ask Planning and Zoning about the parcel's district and proposed structure16.
How do septic permits work in McKenzie County?
Before septic installation begins in McKenzie County, obtain the local public-health-unit permit; Upper Missouri District Health Unit is the county's local authority35. Its McKenzie County office is at the McKenzie County Courthouse, 201 5th St NW Suite 1100, Watford City, ND 58854; call 701-444-344921.
North Dakota DEQ licenses onsite-wastewater installers, while the local health unit issues installation permits and installers must follow local codes224. DEQ also holds statewide rulemaking authority23. A required septic inspection may be in person or virtual, and the public health unit must conduct it within one business day after receiving the request24. McKenzie County's ordinance requires subdivision development to use an approved onsite sewage system and prohibits privies, outhouses and cesspools in those developments7. Only about 9.5% of county soils are rated without severe limitations for conventional drain fields, so make site evaluation an early purchase contingency25.
Can you live in an RV or tiny home on your land in McKenzie County?
McKenzie County allows temporary occupancy of one RV only on property zoned REC, R-1, R-2, R-3 or R-5A when an existing dwelling is already present7. Occupancy is limited to 60 days per calendar year and no more than 30 consecutive days, and the RV must meet property setbacks7. An RV on agricultural land used exclusively to house farm or ranch workers is excluded from that ordinance section7. The existing-dwelling condition prevents treating this temporary-RV provision as permission to live on a vacant parcel while building7.
Tiny-home occupancy and minimum-dwelling-size rules could not be confirmed, so take the proposed dimensions, foundation and wheel status to Planning and Zoning16. A new residential manufactured home must be installed and inspected by state-licensed professionals before occupancy26. The county does not classify manufactured or mobile homes as permanent dwellings, so confirm parcel eligibility before ordering one7.
What are the steps to build a home in McKenzie County, North Dakota?
- Confirm that the parcel is within McKenzie County's zoning jurisdiction and ask Planning and Zoning for its district, allowed dwelling type and setbacks11816.
- Verify legal access and ask whether county, township or state approach approval is needed; the county driveway rule could not be confirmed, so start with Planning and Zoning16.
- Have the Upper Missouri District Health Unit evaluate the site and issue the required septic permit before installation; use an installer licensed by North Dakota DEQ34.
- Submit county building-permit materials; building, structural alteration or moving a structure cannot begin before permit issuance11.
- Confirm fees and inspections with the Building Department; the Board of County Commissioners approves the fee schedule1715.
- Build to the code provisions enforced by McKenzie County and begin before the permit expires7.
- For a manufactured home, use a state-licensed installer and obtain the required inspection before occupancy26.
What should you check before buying land in McKenzie County?
Make septic feasibility a contract contingency because only about 9.5% of McKenzie County soils are rated without severe limitations for a conventional drain field25. The county averages 15.9 inches of precipitation annually and experiences severe drought in 16.7% of years, so verify a dependable water source2728. A North Dakota Department of Water Resources permit is required when a private well will draw more than 12.5 acre-feet, or 4,073,000 gallons, per year; we could not confirm a separate county well permit10.
Confirm boundaries and access because about 33.5% of McKenzie County is federal land29. About 60.9% of county land has a slope of 15% or less30. McKenzie County has about 5.2 people per square mile and 14,252 residents, so price contractors, utilities and emergency access before closing3132. The effective property-tax rate is about 0.4%, with a median annual bill of $1,473, but obtain a parcel-specific estimate3334.
Watch-outs
- McKenzie County's RV rule does not create a general right to occupy an RV on vacant land while building; the listed districts require an existing dwelling7.
- North Dakota's owner-builder exemption is a discretionary property-tax benefit; no McKenzie County owner-builder building-permit exemption could be confirmed, so ask the Building Department before starting work9115.
- Building-permit fee amounts, driveway approval and floodplain procedures could not be confirmed; ask the Building Department about fees and Planning and Zoning about access and overlays171516.
