North Dakota Takeoff Scope Verification Checklist
Confirm the project jurisdiction in North Dakota
Remote estimating starts with the project address and issued documents. A service-area name does not determine the permit authority, utility requirements, wage basis or actual site conditions.
For the areas discussed here, including Cass County, Burleigh County, Grand Forks County, identify the authority and utility serving the actual parcel rather than applying a statewide assumption.
- Share the permit cover sheet or designer’s code summary, adopted edition and local amendment references.
- Provide utility connection details, meter/backflow selections and the civil-to-building package handoff.
- Use project geotechnical and engineered details for burial, excavation, soil protection and restraint quantities.
- Identify public/private funding and the applicable wage determination before supplying labor rates.
Regional code, soil and wage descriptions on this page require project-specific verification. They are not a permit approval, site survey or published local labor quotation.
Images illustrate estimating subjects. They do not document our local office, a completed client project or local jobsite experience.
- ICC code adoption information and IAPMO adopted-code information
- Federal wage determination records; confirm any separate state/local requirements with the relevant authority.
- Reconcile civil and building plumbing plans
- Send the jurisdiction and drawings for a scope review

North Dakota Plumbing Code & Regulatory Environment
Commercial plumbing in North Dakota is regulated statewide by the North Dakota State Plumbing Board pursuant to North Dakota Century Code (N.D.C.C.) Chapter 43-18.
State Adoption Structure
North Dakota adopts the Uniform Plumbing Code (UPC) with state-specific amendments codified in NDAC Title 62. The code applies uniformly statewide across all 53 counties.
State vs. Local AHJ Authority
State plumbing inspectors conduct commercial plan reviews and inspections in rural counties and cities, working alongside local municipal departments in Fargo, Bismarck, and Grand Forks.
Key Statutory Plumbing Requirements:
- Commercial plumbing installations must be permitted by an individual holding a Master Plumber license from the North Dakota State Plumbing Board.
- Backflow prevention assemblies must comply with North Dakota Department of Environmental Quality (NDDEQ) rules and local purveyor standards.
- Water services must be buried at least 6 feet deep or equipped with engineered insulation and heat trace cables.
- Industrial oil/water interceptors must be sized according to state and local pre-treatment criteria.

Regional Construction Conditions & Site Geotechnical Factors
Regional factors to confirm against the project geotechnical report, engineered details, and permit requirements.
North Dakota experiences the most severe winter frost penetration in the continental U.S., requiring 60 to 72 inches (5 to 6 feet) of burial cover statewide. Electric trace heating and rigid polyisocyanurate insulation boards are mandatory on shallow entries.
Eastern North Dakota (Fargo, Grand Forks) is covered by dense, highly plastic Red River Valley lacustrine clays with extreme shrink-swell potential. Western North Dakota features glacial till and Bakken shale.
Commercial projects along the Red, Missouri, and Souris rivers encounter elevated seasonal water tables requiring dewatering.
North Dakota is located in the lowest seismic hazard category (Category A). Highly alkaline soils require polywrap on underground ductile iron.
I-94 and I-29 corridors connect major cities; winter blizzards between November and April require temporary heating and scheduling allowances.
