The following statewide building codes and regulations apply universally to all jurisdictions within North Dakota:
North Dakota Hvac Legislation, Codes, and Guidelines
North Dakota State Building Code and HVAC Legislation
The North Dakota State Building Code is established under North Dakota Century Code (N.D.C.C.) Chapter 54-21.3. This legislation mandates that the state building code must consist of nationally recognized standards, specifically the International Building Code (IBC), International Residential Code (IRC), International Mechanical Code (IMC), and International Fuel Gas Code (IFGC), along with the International Energy Conservation Code and the International Existing Building Code. As of January 1, 2026, the state has adopted the 2024 editions of these codes.
While the state establishes these standards, the North Dakota Department of Commerce, through its Division of Community Services, is the primary agency responsible for adopting rules to implement, amend, and periodically update the state building code. This process is conducted in cooperation with the Building Code Advisory Committee, which includes representatives from various professional organizations such as architects, engineers, building officials, and contractors.
It is important to note that the North Dakota Department of Commerce does not enforce the building code. Enforcement is the responsibility of local jurisdictions (cities, townships, and counties) that elect to adopt and enforce building codes within their boundaries. These local jurisdictions are required to adopt the state building code but may amend it to conform to local needs. Additionally, state agencies are responsible for ensuring their own construction projects comply with the state building code.
