A building permit is required before constructing a home in rural Morton County, North Dakota.1 Unincorporated land is also subject to county zoning, and a new or replacement onsite septic system needs a permit from Western Plains Public Health.23 Start with Planning and Zoning because access, addressing, septic and floodplain requirements can affect whether a building-permit application is ready.4

Do you need a building permit in Morton County, North Dakota?
Yes. Morton County’s rural-home guidance directs an owner to obtain a building permit before constructing a home.1 The Building Inspector page says an owner or authorized agent must apply before covered construction, enlargement, alteration, repair, relocation, demolition, occupancy changes or regulated system work begins.7
Permitted work is subject to inspection and must remain accessible and exposed until the Building Inspector approves it.5 A building under county building-code jurisdiction may not be used or occupied until the building official issues a certificate of occupancy.8 Fee information is available from the Building Inspector office by phone.7
North Dakota’s current state-code framework uses the adopted building-code editions and amendments that took effect in 2026, but state Community Services does not enforce that code itself.910 The county’s precise adoption instrument and complete jurisdictional scope could not be confirmed, so ask the Building Inspector which code edition and local amendments govern the parcel.7
Who issues Morton County building permits, and how do you reach them?
The Morton County Building Inspector Department handles building permits and inspections, with contact information published through the county’s Tax Equalization office.7 The office is at 210 2nd Ave NW in Mandan, and its published phone and email are listed above.7
Planning and Zoning is a separate stop for zoning-district, subdivision, setback and floodplain questions on unincorporated land.2 The department administers county zoning and subdivision regulations and handles floodplain administration outside incorporated cities and townships.11 Its online map provides zoning-district, future-land-use and flood information.11
Permit authority changes inside incorporated places: the county’s land-use code governs unincorporated areas, while cities and townships may administer their own rules or extraterritorial controls.2 Confirm the parcel’s jurisdiction with Planning and Zoning before relying on a county form.11
Does Morton County have zoning?
Yes. The Morton County Land Use Code governs zoning, subdivision, setbacks, approaches, area regulations, floodplains, stormwater management, parking and other development matters in unincorporated Morton County.2 The county publishes a GIS map with zoning-district, future-land-use and flood information, but a map label alone does not replace confirmation of the standards for a particular parcel.12
The available material does not confirm a single countywide answer for long-term RV occupancy, tiny-home occupancy, minimum dwelling size, lot coverage or building height. Ask Planning and Zoning to identify the parcel’s district and the sections that apply to the proposed use.11 A temporary-use application exists, but the substantive private-land camping limits could not be confirmed from the available rules.2
North Dakota exempts a building used for agricultural purposes from the state building-code chapter unless the building is for human habitation or public use; that exemption does not establish an exemption from Morton County zoning or every local permit.13
How do septic permits work in Morton County?
Western Plains Public Health issues onsite septic permits for Morton County.14 For a rural home, obtain the septic permit before the building-permit application is eligible; the health unit requires the property’s assigned emergency address for the application.3 That sequence makes the approach and addressing step important early in the project.4
North Dakota also requires an onsite-system installer to hold a state license and secure the local public-health permit before beginning work.15 Morton County-specific inspection requirements and alternative off-grid sanitation rules could not be confirmed, so ask Western Plains Public Health about design review, inspections and acceptable systems before committing to a house site.16
Only about 14.6% of mapped county soils avoid a “very limited” rating for a conventional septic drain field.17 That soil statistic does not decide an individual site, but it makes early site evaluation especially useful before choosing a building location.17
Can you live in an RV or tiny home in Morton County?
Morton County’s available materials do not provide a confirmed blanket rule for living long-term in an RV on private land or occupying a tiny home. Because the county regulates land use in unincorporated areas, ask Planning and Zoning about the parcel’s district, allowed dwelling types, temporary-use approval, setbacks and any minimum-size standard before buying or moving a unit onsite.211
Do not use North Dakota’s state-park camping limit as the answer for private property: that rule applies to state-park campsites and cabins, not private-land occupancy.18 A new manufactured home installed for residential use in North Dakota must be installed by a state-licensed installer and inspected by a state-licensed inspector.19 That statewide installation rule does not by itself establish where Morton County zoning allows a manufactured or tiny home.2
The county materials also do not confirm an owner-builder exemption from permitting or inspection, so ask the Building Inspector before assuming self-performed work changes the requirements.7
Building a home in Morton County: what are the steps?
Morton County publishes a rural-development sequence that links zoning review, utilities, access, addressing, septic and the building permit.4
- Ask Planning and Zoning to confirm the parcel, zoning district, development path and any subdivision or floodplain approval.220
- Confirm electric, water, phone and cable availability because providers must approve connections and service may be unavailable or expensive.21
- Obtain the approach permit and emergency address for a new residence outside city limits, even when using an existing approach to a county road.6
- Apply to Western Plains Public Health for the septic permit using the assigned emergency address.3
- Apply to the Building Inspector for the building permit and ask for the current fee.17
- Keep permitted work accessible for inspections and obtain the required certificate of occupancy before use.58
What should you check before buying land in Morton County?
Start with jurisdiction and zoning: Morton County regulates unincorporated land, while incorporated cities and townships may administer different or extraterritorial rules.2 Check the county GIS for the zoning district and flood information, then confirm the applicable standards with Planning and Zoning.1211
Verify legal access and approach approval before treating an existing driveway as build-ready, because a new residence outside city limits needs an approach permit even when it will use an existing county-road approach.6 Confirm utility capacity and connection cost directly with providers.21 Arrange septic site evaluation early because only about 14.6% of mapped soils avoid severe conventional drain-field limitations.17
For a private well, a North Dakota water-appropriation permit is required when annual withdrawal exceeds 12.5 acre-feet; lower-volume domestic uses must still be reported under the stated state conditions.22 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 levies.23
Watch-outs
- A county-road driveway already on the land does not eliminate the approach-permit step for a new residence outside city limits.6
- Floodplain development can trigger an additional county permit and elevation requirements, so confirm the mapped flood status before fixing the house site.20
- RV living, tiny-home occupancy and an owner-builder exemption could not be confirmed; ask Planning and Zoning and the Building Inspector before relying on those assumptions.117
