Wyoming Remodeler Legislation, Codes, and Guidelines

Wyoming State Building Codes for Remodelers and Residential Renovations

Wyoming does not have a single, statewide building code. Instead, building codes are adopted and enforced locally by cities and counties. Most jurisdictions in Wyoming adopt the International Codes (I-Codes) published by the International Code Council (ICC), often with local amendments. The state does not mandate adoption or enforcement, allowing each jurisdiction to choose which code editions to use and how to apply them. This means building code requirements can vary across Wyoming, making it crucial for remodelers and designers to check with local building departments before starting a project.

As of June 28, 2024, the State of Wyoming has adopted the 2024 International Codes. This includes the following:

Some local jurisdictions may have adopted different editions or have specific amendments. For example, Laramie County has adopted the 2024 editions of several International Codes, including the IBC, IEBC, and IRC, with amendments effective January 1, 2025. Fremont County has adopted the 2024 International Building, Existing Building, Mechanical, Fire, and Fuel Gas Codes, as well as the 2024 National Electric Code.

Primary State Boards or Agencies

The State of Wyoming has a State Fire Marshal and Building Official, who is part of the Department of Fire Prevention and Electrical Safety. This department is responsible for plan reviews and ensuring compliance with applicable fire and electrical safety standards for certain types of construction and remodeling projects. The Wyoming State Building Commission (SBC) is comprised of the state's five elected officials and plays a role in the management of construction projects.

However, the primary enforcement of building codes for residential renovations and remodeler activities typically falls to local city and county building departments.

Classification of Remodels and Demolition Guidelines

Wyoming state statutes and codes do not explicitly differentiate between "cosmetic" and "structural" remodels in a way that is universally defined across all jurisdictions. However, the scope of work generally dictates when permits and inspections are required. Minor cosmetic changes, such as painting or replacing flooring, may not require a permit. In contrast, alterations that affect structural integrity, change occupancy, or involve significant modifications to the building's systems (electrical, plumbing, mechanical) will require permits and adherence to the adopted building codes.

Converting attics or basements to habitable living spaces is considered a structural alteration and will require a building permit and compliance with the relevant sections of the adopted building codes, such as the International Residential Code (IRC) or International Existing Building Code (IEBC).

Demolition guidelines are typically addressed at the local level, but state regulations also apply. For instance, Section 3303 of the International Building Code (IBC) is referenced for demolition requirements in Cheyenne. A demolition permit is generally required for removing or demolishing any building or structure. Specific requirements often include obtaining a permit, providing proof of insurance, and potentially posting a bond. The State of Wyoming Air Quality Division also has requirements for asbestos demolition and renovation.

Projects costing $40,000 or more may require a plan review by the State Fire Marshal, especially for alterations and remodeling of certain types of buildings. Additionally, any remodeling that affects a built-in fire protection system may require review, regardless of cost.
