Washoe County, Nevada Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Roofing Permit Requirements in Unincorporated Washoe County

In Washoe County, Nevada, the Building and Safety Division is responsible for issuing building permits for properties located within unincorporated areas of the county. If your property is located within an incorporated city, such as Reno or Sparks, you must contact that city's respective building department for permit requirements.

For projects in unincorporated Washoe County, a reroofing permit is required. The county utilizes the OneNV/Accela online portal for permit applications. Key considerations for roofing projects include:

Application Process: Applications must be submitted online via the OneNV portal. Certain reroofing projects may be eligible for the "EZ Permit" process, though these still require review by a permit technician to ensure all necessary documentation is provided.
Documentation and Requirements: Applicants must provide details such as the type of roofing material, the number of layers, and the weight of the material per square foot.
Engineering: If the weight of the new roofing material exceeds 8 lbs per square foot, engineering documentation may be required.
Ice Dams: For properties located at elevations above 5,300 feet, an ice dam protection system is required.
HOA Approval: If the property is located within an active Homeowners Association (HOA), written approval from the HOA must be submitted with the permit application.
Owner/Builder: If you are acting as an owner/builder, you must complete and include an Owner/Builder Affidavit with your application.

Nevada Roofing Legislation, Codes, and Guidelines

Building Codes and Legislation for Roofing in Nevada

Nevada does not enforce a single, uniform statewide building code for all private construction. Instead, building codes are primarily adopted and enforced at the local level (cities and counties). These local jurisdictions typically adopt and amend model codes, such as the International Building Code (IBC) and the International Residential Code (IRC), to suit regional needs, including specific requirements for roofing materials, installation, and fire safety.

While local jurisdictions hold primary authority for private projects, the State of Nevada Public Works Division (SPWD) establishes design standards for state-owned and operated buildings. The SPWD adopts specific editions of model codes (such as the 2024 IBC and IRC) to govern state construction projects. These standards often include specific requirements for roofing systems, such as minimum slope, membrane thickness, and reflectivity.

Roofing contractors in Nevada must be licensed by the Nevada State Contractors Board (NSCB). The C-15 and C-15A license classifications authorize contractors to perform roofing work, including the installation, alteration, and repair of various roofing materials, in compliance with the applicable local building codes.
