Matanuska Susitna Borough, Alaska Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Matanuska-Susitna Borough Roofing Permit Requirements

In the Matanuska-Susitna Borough (MSB), Alaska, roofing projects on properties in unincorporated areas are primarily governed by the MSB Permit Center, which handles land use permits, floodplain development permits, and fire/life safety plan reviews. Traditional building permits for single-family residential construction are not separately administered at the borough level. Instead, the focus is on ensuring compliance with land use regulations.

Permit Authority and Jurisdiction

The Matanuska-Susitna Borough Permit Center is responsible for development permits in all unincorporated areas of the borough. Properties within the city limits of Wasilla, Palmer, or Houston are subject to their respective city's permit requirements.

Rules for Properties in Unincorporated Areas

For properties in unincorporated areas, several types of permits may be relevant to roofing projects, depending on the specific circumstances:

Land Use Permit: Required for new construction, additions, changes of use, clearing, grading, excavation, and resource extraction. This permit ensures that land use follows borough regulations. A Mandatory Land Use Permit (MLUP) is specifically required if you plan to build or place any structure within 75 feet of a watercourse or waterbody.
Floodplain Development Permit: If the property is located within a Federally Designated Flood Hazard Area, a Floodplain Development Permit is required before any development can occur.
Fire/Life Safety Plan Review: This review is necessary before construction, alteration, or occupancy changes for structures where people work, play, or spend time. However, residential housing that is three-plex or smaller is generally exempt, unless the property is within the city limits of Palmer.
Multifamily Residential Permit: Required for residential developments of more than six units per lot or new construction exceeding two dwellings per 40,000 square feet.

It's important to note that even if a project is exempt from one type of permit, other permit requirements may still apply. It is advisable to confirm specific needs with the Permit Center before starting any work.

Application Process and Requirements

The general application process involves determining the applicable permit type, preparing required documents such as a site plan, and submitting the application online via the EnerGov portal or in person at the Permit Center. Fees are set annually and must be paid. After review and approval, a certificate may need to be posted on-site, and a final inspection scheduled upon project completion.

Alaska Roofing Legislation, Codes, and Guidelines

State-Level Building Codes and Legislation for Roofing in Alaska

Alaska does not have a single, uniform statewide building code that applies to all construction. Instead, the state adopts specific model codes that apply to certain occupancies and facilities under the jurisdiction of the Alaska Department of Public Safety. For most residential and commercial projects, building codes are adopted and enforced at the local level by municipalities and boroughs, which often amend these codes to address Alaska's unique environmental challenges, such as extreme snow loads, permafrost, and subarctic temperatures.

The State of Alaska, through the Division of Fire and Life Safety, has adopted the 2021 editions of the International Building Code (IBC), International Existing Building Code (IEBC), International Fire Code (IFC), International Fuel Gas Code (IFGC), and International Mechanical Code (IMC). These codes serve as the baseline for state-regulated projects. While the International Residential Code (IRC) is not adopted statewide by the state government, it is widely used as a reference and is often adopted by local jurisdictions or required by the Alaska Housing Finance Corporation (AHFC) for residential standards.

Roofing design and installation in Alaska are heavily influenced by structural engineering requirements rather than just prescriptive code tables. Due to the state's extreme climate, roof systems must be designed to withstand significant ground snow loads, which can exceed 300 pounds per square foot in certain regions. Consequently, structural roof design often relies on the American Society of Civil Engineers (ASCE) 7 standard for load calculations, supplemented by local data, to ensure safety and structural integrity.

Primary State Agencies

Alaska Department of Public Safety, Division of Fire and Life Safety: Responsible for adopting and enforcing the state-level building, fire, and mechanical codes for projects under its jurisdiction.
Alaska Division of Corporations, Business and Professional Licensing (DCBPL): Administers contractor registration and licensing requirements under Alaska Statutes Title 08, Chapter 08.18, which governs roofing contractors.
Alaska Housing Finance Corporation (AHFC): Sets residential building standards, including energy efficiency requirements (BEES), which influence roofing insulation and ventilation practices for residential construction.
