Barnes County Building and Safety Jurisdiction

In Barnes County, North Dakota, building permits and development code compliance are managed by the Barnes County Planning & Zoning (P&Z) Department.

Rules for Properties in Unincorporated Areas

For properties located in unincorporated areas of Barnes County, the following rules generally apply:

Permit Requirement: Any person intending to construct, reconstruct, make additions to, or relocate a building over 150 square feet must obtain a building permit before beginning work or excavation.
Building Code: Barnes County follows the North Dakota State Building Code (IBC 2018(A) with amendments).
HVAC and Mechanical Work: While the county oversees general building permits, specific mechanical, electrical, and plumbing work often falls under state-level oversight or specialized inspection requirements. It is essential to verify with the Barnes County P&Z Administrator whether your specific HVAC project requires a county permit or if it is subject to other state-level requirements.
Inspections: The county requires specific inspections throughout the construction process. For example, "Rough Mechanical" inspections are required after vents, chimneys, heat ducts, and combustion air ducts have been installed but before they are concealed.
Exemptions: Structures 150 square feet or less generally do not require a permit. Always confirm with the P&Z Administrator if your specific project qualifies for an exemption.

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.
