A building permit in Williston is issued by the city's Development Services Building Department, which administers the North Dakota State Building Code and inspects the work. As of the first of January 2026 the city follows the 2024 International Building Code, and the state contractor licence and the state trade boards run alongside the city permit.
Williston grew explosively through the Bakken oil boom, and its Building Department is built for volume and for verification. The city issues a permit only to a contractor licensed and bonded by the State of North Dakota and wants a copy of the licence, with its class and renewal date, on file before the permit issues — so an out-of-town contractor confirms the state licence first. And any land-disturbing activity of five thousand square feet or more requires a grading and erosion-control plan before development proceeds.
This guide covers the city of Williston, in Williams County. Williams County runs a separate Building Division for construction on property in the unincorporated county, so confirm whether the site is inside the city or in the county before filing.
The state contractor licence is checked before the permit. Because Williston issues a building permit only to a contractor licensed and bonded by the State of North Dakota and wants a copy of the licence and its class on file first, confirming the state licence is current is the step that precedes the permit, not one that follows it.
What requires a building permit in Williston?
North Dakota has a State Building Code, but whether it is enforced where you build is a local choice. The State Building Code, under North Dakota Century Code chapter 54-21.3, is a uniform standard built on the International Codes, and a city, county or township that elects to enforce a building code must adopt it — so the enforcing jurisdictions share one code rather than a patchwork of editions. But enforcement is not mandatory: the state itself enforces the code only on state buildings, and in a place that has established no building department there is no local enforcement for private work. Two things run statewide regardless — a state contractor's licence for larger jobs and the state boards that regulate the electrical and plumbing trades. So in Williston the questions are whether a building code is enforced, which local amendments apply, and that the city has moved to the 2024 building code, and that it requires a copy of the contractor's North Dakota licence, with its class, before a permit issues.
The statewide layer has three parts. A contractor's licence from the Secretary of State is required for any job whose value exceeds four thousand dollars, in four classes by project value, so most commercial and much residential work carries one before a permit is pulled. Electrical work is regulated by the North Dakota State Electrical Board, which licenses electricians, adopts the National Electrical Code and inspects wiring statewide through its district inspectors; plumbing runs through the State Plumbing Board. And buildings used exclusively for agriculture on a farm or ranch are exempt from the State Building Code, though that exemption is narrow and falls away once residential or commercial use enters.
Typically permit required
- A City of Williston building permit from Development Services for construction, additions, most alterations and demolition
- A grading and erosion-control plan for land-disturbing activity of five thousand square feet or more
- A North Dakota contractor's licence from the Secretary of State for any job whose value exceeds four thousand dollars, in the class that fits the project value
- An electrical permit and inspection under the North Dakota State Electrical Board, which regulates electrical work statewide
- A plumbing permit under the North Dakota State Plumbing Board, which regulates plumbing statewide
- The State Building Code as the city has adopted and amended it, where the city enforces a building code
Often exempt
- Detached accessory structures below the city's threshold, where zoning setbacks still apply
- The State Building Code on buildings used exclusively for agriculture on a farm or ranch
- A local building permit in a jurisdiction that has established no building department — much of rural North Dakota
- A state contractor's licence on work whose value does not exceed four thousand dollars
- Ordinary repairs the adopted code places below the permit threshold
Whether a building code is enforced where you are building
North Dakota's code is uniform but its enforcement is local and optional. Inside a city that has established a building department — the larger cities have — the city administers the State Building Code with any local amendments and issues the permit. A city or township enforces only within its own area; a county administers the code in the parts of the county no city or township covers, and a city may relinquish its authority to the county. Where no jurisdiction has established a building department, there is no local building permit for private construction, though the state contractor licence and the state electrical and plumbing rules still apply. Beyond that, Williston administers the North Dakota State Building Code through its Development Services Building Department, and as of the first of January 2026 it follows the 2024 International Building Code with the ASCE 7-22 loading standard, a forty-eight-inch frost depth and a seismic category of zero — ahead of many North Dakota jurisdictions. Two local rules shape the front end: the city issues a building permit only to a contractor licensed and bonded by the State of North Dakota, and it requires a copy of that licence, showing its class and renewal date, on file first; and a grading and erosion-control plan is required for land-disturbing activity from five thousand square feet upward.

Permit types
Residential permits
Houses, additions, alterations, decks and garages inside the city are permitted through Development Services under the State Building Code on the 2024 editions. The contractor's North Dakota licence is confirmed and on file, a grading and erosion-control plan is required for land-disturbing activity of five thousand square feet or more, and the electrical is inspected under the State Electrical Board.
How North Dakota contractor and trade credentials work
North Dakota licenses at two levels. A general contractor needs a state contractor's licence from the Secretary of State for any job over four thousand dollars, issued in four classes — Class A with no value limit, then Class B, C and D by decreasing project value — and renewed each year by the first of March; it needs liability insurance and Workforce Safety and Insurance coverage but no state exam or bond. The trades are separate and stricter: electricians are licensed by the State Electrical Board and plumbers by the State Plumbing Board, both by examination. Some cities add their own licence — mechanical and heating contractors are licensed at the city level in the larger cities rather than by the state. In Williston the licence is checked when the permit issues.
Commercial permits
Commercial and multi-family projects are reviewed under the State Building Code on the 2024 editions, with the contractor's state licence class matched to the project value and a North Dakota engineer's seal on structural work. A grading and erosion-control plan governs site disturbance, and electrical runs under the State Electrical Board.
The state permits and boards that run alongside the local permit
Alongside a North Dakota building permit, several state processes run in parallel. The State Electrical Board issues the electrical permit and inspects the wiring — through a district inspector, or a local electrical inspector operating under the board's rules in the larger cities, with the board billing the fee. The State Plumbing Board governs plumbing. And on any job over four thousand dollars the Secretary of State contractor's licence must be current. In Williston the electrical work is inspected under the North Dakota State Electrical Board and plumbing under the State Plumbing Board, alongside the city building permit.
Williston permit costs and fees
Williston scales its building permit to the project. The cost dimensions particular to the city are the grading and erosion-control plan on a disturbed site and the state contractor licence class, which must reach the project value.
| Item | Fee or rule |
|---|---|
| Building permit | Scaled to project valuation under the city's fee schedule and confirmed at intake |
| Erosion control | A grading and erosion-control plan for land-disturbing activity of five thousand square feet or more |
| Contractor licence | A Secretary of State contractor's licence in the class fitting the project value, on file before the permit issues |
| Electrical and plumbing | Permitted and inspected under the state boards, billed separately from the city |
Match the licence class to the job. Because Williston records the class of the contractor's state licence before issuing, a contractor whose class does not reach the project value cannot be permitted for it — so the licence class is matched to the job before the permit, not after.
Trade permits and who may pull them
Trade work in North Dakota is licensed by the state even where the building code is enforced locally. Electricians and plumbers hold state licences and are inspected through the state boards, and a general contractor holds a Secretary of State licence keyed to the value of the job.
Permit required
- Electrical — by an electrician licensed by the State Electrical Board, permitted and inspected under the board statewide
- Plumbing — by a plumber licensed by the State Plumbing Board
- General contracting — under a Secretary of State contractor's licence for any job over four thousand dollars
- Mechanical and heating — under the adopted mechanical code, with a city licence where the city licenses the trade
Typically exempt
- Work whose value does not exceed four thousand dollars, below the state contractor-licence threshold
- Like-for-like replacement not amounting to a new installation
How to apply for a Williston building permit
The larger cities have building departments; many rural counties and townships have none, and then there is no local building permit for private work.
The city within its limits, the county in the areas no city or township covers, each administering the State Building Code with any local amendments.
Required for any job over four thousand dollars, in the class that fits the project value, renewed by the first of March.
From the State Electrical Board and State Plumbing Board, which license and inspect those trades statewide.
To the city building department, against the adopted State Building Code and the city's local amendments.
City building inspections, state electrical and plumbing inspections, then the certificate of occupancy where a code is enforced.
Review, corrections and what actually causes delay
The Williston delays that recur are licence and site delays: a contractor whose state licence was not on file or whose class does not reach the project value, or a disturbed site without a grading and erosion-control plan. Confirming the state licence and its class, filing the erosion-control plan, and running the state trade permits in parallel keep the review on track.
Inspections in Williston
Where a city enforces the code, inspections follow the sequence in the adopted edition — footing, foundation, framing, rough trades, insulation and final — requested from the city against the permit number. Electrical inspection runs through the State Electrical Board, by a district or local inspector under the board's rules, and its approval is a precondition of energizing the service and of occupancy; plumbing runs through the State Plumbing Board. A certificate of occupancy closes the file where a code is enforced. In Williston the building inspections run through Development Services against the permit number; the electrical inspection is carried out under the State Electrical Board, and plumbing under the State Plumbing Board.

Frequently asked questions
Which building code does Williston use?
As of the first of January 2026, the North Dakota State Building Code on the 2024 International Building Code with the ASCE 7-22 loading standard, a forty-eight-inch frost depth and a seismic category of zero. Confirm the current edition set with Development Services.
Does the city check my contractor's licence before permitting?
Yes. Williston issues a building permit only to a contractor licensed and bonded by the State of North Dakota, and it requires a copy of the licence, showing its class and renewal date, on file before the permit issues.
When do I need a grading and erosion-control plan?
For land-disturbing activity of five thousand square feet or more. The plan is required before development proceeds, so it belongs in the project's early steps rather than at permit intake.
Does the city or the county handle my project?
The City of Williston permits work inside the city; Williams County runs a separate Building Division for construction on property in the unincorporated county. Confirm which authority holds the address before filing.
Who inspects electrical and plumbing?
The North Dakota State Electrical Board and the North Dakota State Plumbing Board, which regulate those trades statewide. The city inspects the building itself.
Do I need a state contractor's licence?
For any job whose value exceeds four thousand dollars, yes — a North Dakota contractor's licence from the Secretary of State, in the class that fits the project value, renewed by the first of March.
