Do you need a building permit in Billings County, North Dakota?
Yes. Billings County requires a building permit for new construction and move-in structures, including modular homes.1 A Building & Zoning Certificate is also required before new construction, moving a structure, changing exterior dimensions or use, or subdividing land.1 Permitted construction receives field inspections, including a final inspection before the certificate-of-occupancy process.11 The completed building may not be occupied until the certificate of occupancy is issued.12
Billings County applies the state building code during plan review.13 Agricultural land and buildings have a limited zoning exemption, but county road setbacks and floodplain rules still apply.14 A home does not fall within North Dakota's separate agricultural building-code exemption merely because it is on agricultural land.15
Who is the Billings County building department, and how do you reach it?
Start with Billings County Planning & Zoning at the contact above. The county application goes to the zoning office with the checklist and deposit; after a completeness check, zoning approval comes before Building Department plan review.16 For technical building questions and inspections, the county directs applicants to Building Department and Inspections at 701-260-5373.17
Plan review is generally about two weeks but is not guaranteed.16 Published deposits are $200 for a single-family residence or modular or manufactured home; commercial deposits rise with project size, and the balance is set after review.18 A reinspection fee applies when work is not ready.18 Ask Planning & Zoning for the current total fee and meeting schedule before committing to a start date.17
Does Billings County have zoning?
Yes. Billings County zoning regulates unincorporated territory, while the City of Medora has a one-mile extraterritorial zoning area where municipal rules may apply.19 The county ordinance establishes Agricultural, Residential, Recreation, Commercial, Industrial, and Hillside and Ridgeline Overlay districts.20 Confirm the parcel's jurisdiction and district before designing the project.
Agricultural and Residential districts generally require five-acre lots, although certain older residential lots and major subdivisions have different standards.9 Buildings must generally stand at least 103 feet from a section-line or county-road centerline and 250 feet from a state-highway centerline; district yard rules also apply.21 Accessory buildings must be at least 10 feet from lot lines and may be no taller than 15 feet.2122 Short-term rentals require conditional-use approval from both the Zoning Board and County Commission before nightly, weekly or other short-term rental begins.23
How do septic permits work in Billings County?
Submit the sewage and water facilities application to Southwestern District Health Unit.3 An approved septic permit must accompany the Billings County building permit application.4 The installed system must be inspected before it is covered and again onsite for final approval.24 State rules also require the permitting authority to inspect an onsite wastewater installation within one business day after an inspection request.25
Only about 13.8% of mapped Billings County soils are rated without severe limitations for a conventional drain field, so arrange a site evaluation before fixing the house location.26 Household wastewater must receive septic-tank or higher treatment before soil discharge; if underground dispersal is infeasible, the permitting authority may review an alternative, but approval is not automatic.27 Ask Environmental Health to approve the proposed system before relying on an off-grid design.28
Can you live in an RV or tiny home in Billings County?
Billings County allows an RV as a temporary residence only under stated conditions: in a licensed RV park, through conditional use in a Residential District, or under the ordinance's temporary-camping provisions.5 A qualifying property with an occupied permanent dwelling may host up to two RVs, with approved septic, potable water, utility service, separation and setback requirements; stays totaling less than 30 days in a 12-month period are exempt from those provisions.5 During construction in a Residential District, an RV or mobile home may be conditionally approved as a temporary residence for no longer than one year from building-permit issuance.6
We could not confirm a separate tiny-home occupancy rule. A tiny home built or moved onto land should not be assumed exempt from county building and zoning approval.1 Mobile homes on platted Residential District lots require a permanent foundation or properly anchored concrete basement, with wheels and hitches removed.29
Building a home in Billings County: what are the steps?
Ask Billings County Planning & Zoning to confirm whether county zoning or Medora's extraterritorial zoning controls the parcel, then identify the zoning district.19
Check lot size, road and highway setbacks, floodplain status, and the proposed building location.92110
Obtain Southwestern District Health Unit approval for the septic system and plan for inspection before covering it.424
Secure the required road approach permit; a state-highway driveway requires NDDOT approval, while the county building application requires its road approach permit.3031
Submit the complete building and zoning application, checklist and deposit, then allow time for zoning approval and plan review.1618
Schedule field inspections and do not occupy the completed building until the certificate of occupancy is issued.1112
What should you check before buying land in Billings County?
Confirm zoning jurisdiction, district, buildable area and legal access before closing. Medora's extraterritorial area can change the zoning authority, and county road and state-highway approaches have separate approval paths.193031 Check setbacks early because county-road and state-highway centerline distances can materially shrink a homesite.21
Map floodplain exposure as well as soils. A county floodplain development permit is required before construction or manufactured-home placement in county floodplain jurisdiction outside Medora and its extraterritorial area.10 Conventional septic suitability is severely limited across most mapped soils.26 For a private well, North Dakota requires a water-appropriation permit above 12.5 acre-feet per year and reporting for qualifying lower-volume uses.32 Billings County's effective property-tax rate is about 0.4%, and its median annual property-tax bill is about $1,189.3334
Watch-outs
Do not occupy a permitted building before Billings County issues its certificate of occupancy.12
A county floodplain development permit is required before construction or manufactured-home placement in county floodplain jurisdiction.10
RV residence is conditional or temporary, and construction-site occupancy is limited to one year from building-permit issuance.56
Short-term rental use needs Zoning Board and County Commission approval before renting begins.23

North Dakota rules that apply here
Owner-builder exemptionConditional
An individual who builds that individual’s own single-family residence and seeks the North Dakota builder property-tax exemption.
The exemption is discretionary and requires the governing city or county to pass a resolution allowing it.
For property within a city, the city governing body has jurisdiction; for property outside an incorporated city, the county has jurisdiction.
The property must remain owned by the builder and unoccupied.
The exemption applies for the taxable year in which construction began and the next two taxable years.
The governing body may impose conditions, including limits on the exemption period and dollar value.
A builder may receive the exemption for no more than ten properties in a taxable year within each jurisdiction that approved the exemption.
General taxes and installments of special assessments may not be delinquent.
This is a property-tax exemption, not a building-permit or building-inspection exemption.
exemption period: taxable year in which construction began and next two taxable years · maximum properties per builder per jurisdiction per taxable year: 10 properties
“Whether or not to offer the exemption is at the discretion of the governing body. [...] “Builder” includes an individual who builds that individual’s own residence.”

county zoning authorityGeneral
North Dakota counties adopting zoning regulations for land and buildings within the county, including unincorporated areas.
The authority is exercised by the board of county commissioners.
Regulation is subject to North Dakota Century Code chapter 54-21.3.
The authority covers the location and use of buildings and structures and the use, condition of use, or occupancy of lands for residence, recreation, and other purposes.
County zoning regulations must be made in accordance with a comprehensive plan.
A county may divide all or any parts of the county into districts, and regulations must be uniform within each district but may differ between districts.
County zoning regulations must account for the statutory limitations governing farming, ranching, and animal feeding operations in section 11-33-02.1.
The board must state the grounds for approving or disapproving zoning amendments or variances, and written findings must be included in the records.
The board must establish zoning requirements for solid waste disposal and incineration facilities before July 1, 1994.
The board may impose tipping or other fees on solid waste management and incineration facilities, but may not impose a fee under this section on an energy conversion facility or coal mining operation that disposes of its waste onsite.
The board may establish institutional controls addressing environmental concerns with the department of environmental quality under section 23.1-10-16.
“For the purpose of promoting health, safety, morals, public convenience, general prosperity, and public welfare, the board of county commissioners of any county may regulate and restrict within the county, subject to chapter 54-21.3, the location and the use of buildings and structures and the use, condition of use, or occupancy of lands for residence, recreation, and other purposes.”

“the board of county commissioners of any county may regulate and restrict within the county”
county building authorityGeneral
County authority to administer and enforce the state building code, including the residential code, and to provide for building permits for buildings or structures subject to county zoning in unincorporated areas of North Dakota.
A county that elects to administer and enforce a building code must adopt and enforce the state building code; it may amend that code to conform to local needs.
A county may administer and enforce the state building code only in areas where a city or township does not administer it. A city or township may relinquish that authority to its county under N.D.C.C. § 54-40.5-03; local governments may also agree to joint administration and enforcement or contract for private enforcement.
County permit authority under N.D.C.C. § 11-33-18 applies to a building or structure otherwise subject to the County Zoning chapter.
If the county provides for permits, it must require the applicant to state whether the structure is reasonably anticipated to have a significant transportation-system impact. A structure has such impact if it will average at least twenty-five motor vehicles per day during one year with gross weight exceeding sixty thousand pounds [27215.54 kilograms].
For a structure with significant transportation-system impact, the county must notify the director of the department of transportation and allow an opportunity to comment; director approval is not required.
The county may establish and collect reasonable permit fees, which must be credited to the county general fund.
A county-adopted building code may not require fire sprinklers in a single-family dwelling or a residential building containing no more than two dwelling units.
significant transportation-system impact threshold: >= 25 motor vehicles per day (Over a period of one year; vehicles must have gross weight exceeding sixty thousand pounds [27215.54 kilograms].) · fire-sprinkler requirement: false (A county building code may not require sprinklers in a single-family dwelling or residential building with no more than two dwelling units.)
“The governing body of a city, township, or county that elects to administer and enforce a building code shall adopt and enforce the state building code. However, the state building code may be amended by cities, townships, and counties to conform to local needs.”
