North Dakota Remodeler Legislation, Codes, and Guidelines

North Dakota Building Codes for Remodelers and Residential Renovations

North Dakota has adopted the 2021 International Building Code (IBC), International Residential Code (IRC), International Mechanical Code (IMC), International Fuel Gas Code (IFGC), International Energy Conservation Code (IECC), and the International Existing Building Code (IEBC) as the foundation for its state building code. These codes were effective as of January 1, 2023. Updates to the 2024 versions of these codes have been adopted and will go into effect on January 1, 2026.

It's important to note that while the state establishes the building code, enforcement is primarily handled by local city and county jurisdictions. These local authorities, known as Authorities Having Jurisdiction (AHJ), may adopt additional regulations or amendments to the state code to suit local needs.

1. Adopted State Statutes and Codes

The state building code does not automatically include the International Property Maintenance Code or the International Fire Code; these must be adopted separately by local jurisdictions.

2. Primary State Board or Agencies

The North Dakota Department of Commerce, Division of Community Services, is responsible for updating and amending the North Dakota State Building Code. This is done in cooperation with the State Building Code Advisory Committee, which consists of representatives from various building industry organizations and state agencies. The State Fire Marshal's office also plays a role in fire code adoption and enforcement.

3. Classification of Remodels and Demolition Guidelines

The distinction between cosmetic remodels and structural alterations is generally determined by the scope of work and its impact on the building's structural integrity, safety, and occupancy. Cosmetic remodels, such as interior finishes, cabinet work, or replacing doors and windows without altering rough openings, typically do not require a building permit. However, projects involving the creation or elimination of rooms by adding or removing walls, finishing basements or lower levels, installing or removing doors/windows requiring structural work, replacing structural sheathing, re-siding, or any work altering structural components are considered significant renovations and usually require permits.

Converting attics or basements to habitable living spaces, or any work that alters structural components, would fall under structural alterations and necessitate adherence to the relevant sections of the IBC and IRC. Demolition guidelines are typically addressed at the local level, with specific requirements for permits, bonds, and site cleanup. For instance, a dangerous building that is significantly damaged (50% or more) or poses a fire hazard may be subject to demolition orders.
