Permit Requirements for Riverdale, North Dakota

For HVAC projects in Riverdale, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of McLean County.

Authority Having Jurisdiction (AHJ)

Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:

General HVAC Guidelines

Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Because Riverdale is located within Mclean County, the following broader county regulations may also apply to your project:

McLean County HVAC Permit Requirements

McLean County, North Dakota, requires building permits for mechanical work, which includes HVAC systems, in unincorporated areas. [2] North Dakota does not have a centralized state permitting office; permits are handled at the local city or county level. [3] McLean County specifically issues building permits for properties located in unincorporated areas of the county. If your property is within an incorporated city, that city's building department is responsible for permits. [4]

County Building & Safety Divisions and Jurisdiction

The McLean County Planning and Zoning Department is involved in the building permit process. [2] The Land Use Administrator and the Tax Equalization/Land Use Administration Office are key contacts for building permits and zoning information within the county. [11, 15] For unincorporated areas, McLean County's Planning and Zoning Commission, Land Use Administrator, Auditor, and Board of County Commissioners are responsible for administering and enforcing the County Zoning Ordinance. [14]

Rules for Properties in Unincorporated Areas

In unincorporated McLean County, building permits are required for structural and mechanical work. [2] The application process typically involves contacting the Planning and Zoning Department to verify zoning compliance, obtaining and submitting a building permit application with a site plan and fee, and undergoing a county review for zoning and building code adherence. [2] Inspections can be scheduled through the County Planning and Zoning Department. [2]

The permit fee is calculated as 1/10th of 1% of the construction cost, with a minimum fee of $90.00 and a maximum of $500.00 for residential properties and $1,000.00 for commercial properties. [11]

While North Dakota does not mandate state-level HVAC licensing for contractors, many municipalities do have their own licensing requirements. [7] Separate plumbing and electrical system permits are required for work on those systems, with electrical permits issued by the North Dakota State Electrical Board and plumbing permits by the North Dakota State Plumbing Board.

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.
