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

Yes. Morton County requires a permit for construction, enlargement, alteration, repair, moving, demolition, occupancy changes and regulated building systems in its unincorporated jurisdiction¹. The county has adopted the current North Dakota State Building Code without local amendments; city extraterritorial areas are excluded³.

Permitted work must remain accessible and exposed for inspection until approved⁶. A covered building may not be used or occupied until the building official issues a certificate of occupancy⁶. Call the Building Inspector for the current building-permit fee³.

A farm or ranch building can qualify for an agricultural exemption when it serves farming or ranching on at least 150 contiguous acres under common ownership or operation³. A residence or other building used by the public still needs building and occupancy permits regardless of farm acreage³. Morton County has not stated a general owner-builder exemption, so self-performing the work should not be treated as a way around permits or inspections; confirm contractor and inspection requirements with the Building Inspector⁶.

North Dakota also lets a county exempt a person who builds their own new single-family home from property tax on the improvements, but only if the county commission passes a resolution allowing it⁷. We could not confirm that Morton County has passed one, so ask the Board of County Commissioners before counting on the tax break⁷.

The Morton County Building Inspector Department handles building permits, inspections and certificates of occupancy⁶. Call that office for the current building-permit fee, which is not posted with the county’s published land-use fees³.

Planning and Zoning is the separate stop for zoning districts, subdivision, setbacks and floodplain questions on unincorporated land². The department administers county zoning and subdivision regulations and handles floodplain administration outside incorporated cities and townships¹⁰. Dividing land can require county review, with the Planning and Zoning Commission making a recommendation to the Board of County Commissioners⁵.

Jurisdiction changes by location. Morton County zoning applies in unincorporated areas, but incorporated cities and townships may have their own authority, including city extraterritorial areas¹¹. Confirm the parcel’s jurisdiction with Planning and Zoning before relying on a county form or map¹⁰. Wherever a city or township takes over building permits or zoning, septic permits for the property still come from Western Plains Public Health⁴.

Yes. The Morton County Land Use Code governs zoning, subdivision, setbacks, approaches, floodplains and related development in unincorporated areas, except city extraterritorial areas². The county zoning map establishes the regulatory districts and boundaries for certain unincorporated areas³.

Lot size is district- and utility-specific. In the Agricultural district, the minimum is 35 acres with or without public water and sewer; most unsewered districts require 65,000 or 80,000 square feet, while the unsewered Conservation and Open Space district lists no minimum³. Those figures do not replace septic, access, floodplain, subdivision or use-specific requirements³. Setbacks vary by district, utility service, lot status, structure type and road class; when dimensional and roadway setbacks differ, the greater one controls³. Roadway setbacks are measured from the road centerline: 250 feet for interstates, 135 feet for arterials, 110 feet for rural collectors and 93 feet for section-line roads³. Building height is governed through the adopted state code plus county zoning and overlays³.

We could not confirm a countywide minimum dwelling floor area or a special tiny-home category; ask Planning and Zoning how the proposed dwelling fits the parcel’s district¹⁰. Accessory dwellings may be allowed in Agricultural and Residential districts after Zoning Administrator review, and in the Limited Industrial district with a special-use permit³. In the Agricultural district, a lot of at least 35 acres may have one accessory dwelling and a lot of at least 70 acres may have up to three³.

Western Plains Public Health handles onsite septic permits for Morton County⁴. A rural-home applicant needs an assigned emergency address before applying for septic approval, and the septic permit must be in hand before the county will accept the building-permit application⁵.

A structure with plumbing must discharge to a community, in-ground or mound septic system permitted by the local health district³. A store-and-pump-only system is allowed only when health-district staff recommend it as the best or only alternative, so off-grid ownership does not create a sanitation exemption³. Morton County’s materials do not separately confirm the inspection sequence; ask Western Plains Public Health about site evaluation, design review and inspections before fixing the house site¹².

Only about 14.6% of mapped county soils avoid a “very limited” rating for a conventional septic drain field¹³. That countywide soil measure does not decide an individual parcel, but it makes early site evaluation particularly useful¹³.

We could not confirm a blanket rule for long-term occupancy of one RV on private land in Morton County, so ask Planning and Zoning about the parcel and proposed duration¹⁰. The county regulates RV camps through special-use permits in eligible districts³. Primitive campgrounds are subject to district limits and site-plan review, while temporary-use applications must be filed at least 10 days before the use begins³. Those campground standards do not answer whether one owner may live in an RV indefinitely³.

We could not confirm a distinct Morton County tiny-home rule, so ask the Building Inspector and Planning and Zoning how ordinary zoning, building, sanitation and occupancy requirements apply^6,10. Manufactured housing has additional limits: no mobile or modular home made before 1980 may be placed, and a manufactured-home park needs at least 20 acres plus central utilities³.

Morton County’s rural-development sequence links zoning, utilities, access, addressing, septic and the building permit⁵.

1. Ask Planning and Zoning to confirm jurisdiction, district, lot entitlement, setbacks and any subdivision or floodplain approval^2,3,5.
2. Ask utility providers whether service can be extended and what extension will cost⁵.
3. Obtain the approach permit and emergency address; a new residential project needs access meeting Highway Department engineering standards³.
4. Apply to Western Plains Public Health for the septic permit using the assigned emergency address⁵.
5. Apply to the Building Inspector for the building permit and current fee; separate county land-use fees may apply, including $200 for a floodplain development permit, $50 for a temporary-use permit and $200 for a variance^1,3.
6. Keep permitted work accessible for inspection and obtain the certificate of occupancy before use⁶.

Start with jurisdiction and zoning: Morton County regulates unincorporated land, while cities, townships and city extraterritorial areas may follow different authorities¹¹. Check the county GIS for the zoning district and flood information, then confirm the applicable lot size, setbacks and use with Planning and Zoning^3,10.

Verify legal access before treating an existing driveway as build-ready, and confirm utility availability and extension cost directly with providers^3,5. Arrange septic evaluation early because only about 14.6% of mapped soils avoid severe conventional drain-field limitations¹³. A special flood-hazard site needs a floodplain development permit before work begins³.

A North Dakota water-appropriation permit is required when a private well will draw more than 12.5 acre-feet, or 4,073,000 gallons, per year; a well below that annual threshold does not need the permit⁹. Well construction and pump installation still fall under state rules and contractor licensing⁹. The county’s median property-tax bill is about $2,562 per year, but a parcel-specific estimate should come from the assessed value and applicable levies¹³.
