Utah, Grand County Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Building and Safety Jurisdiction in Grand County, Utah

The Grand County Building Department is responsible for performing building-related functions, including the issuance of permits and conducting inspections, for all of Grand County, which includes unincorporated areas and the Town of Castle Valley. If your property is located within an incorporated city, you must contact that specific city's building department, as they handle their own permitting.

Roofing Permit Requirements for Unincorporated Areas

In unincorporated Grand County, a building permit is generally required before you erect, construct, enlarge, alter, repair, move, improve, remove, convert, or demolish any building or structure. Because roofing work often falls under "alter" or "repair," it is highly recommended to contact the Building Department directly at 435-259-4134 to confirm if your specific roofing project requires a permit before beginning any work.

Additionally, Grand County has specific roofing guidelines that must be followed, regardless of whether a permit is required. These include:

Snow Management: Metal roofs must be designed to prevent snow from shedding onto pedestrian or vehicular exits, sidewalks, streets, and alleys. Snow-stops must be installed per manufacturer recommendations if shedding is likely to occur in these areas.
Vent Pipes: Each vent pipe or stack must terminate within 2.5 feet from the ridge or be equipped with a snow splitter to prevent damage.
Waterproofing: A self-adhering waterproof membrane must be installed on habitable structures from the eaves to at least 6 feet above the outside wall and 30 inches above the center line of all valleys.
Re-roofing: If the old roofing is not removed, a maximum of two layers of roofing is allowed (one layer old, one layer new).
Contractor Licensing: All work must be performed by a Utah State-licensed contractor, including work that may not require a building permit.

Utah Roofing Legislation, Codes, and Guidelines

State Statutes and Adopted Building Codes

In Utah, building construction standards are governed by the State Construction and Fire Codes Act, found in Title 15A of the Utah Code. This legislation establishes the legal framework for the adoption and enforcement of construction codes statewide. As of July 1, 2023, Utah has adopted the 2021 editions of the "I-Codes" published by the International Code Council (ICC), including the 2021 International Building Code (IBC) and the 2021 International Residential Code (IRC). These codes, which include specific provisions for roof assemblies, coverings, and underlayment, are applied with state-specific amendments to address local needs and conditions.

Primary State Board and Agencies

The Uniform Building Code Commission (UBCC) is the primary body responsible for reviewing and recommending building code adoptions and modifications to the Utah State Legislature. The commission is composed of appointed members representing various construction industry stakeholders, including contractors, architects, engineers, and building officials. The UBCC operates under the Division of Professional Licensing (DOPL) within the Utah Department of Commerce. While the state sets these uniform standards, enforcement is typically carried out by local compliance agencies (such as city or county building departments), except for state-owned, leased, or rented facilities, which fall under the jurisdiction of the Division of Facilities Construction and Management (DFCM).
