Hawaii Roofing Legislation, Codes, and Guidelines
State-Level Building Codes and Legislation for Roofing in Hawaii
In Hawaii, building codes are established at the state level but are adopted and enforced by the individual counties. The Hawaii State Building Code Council (SBCC) is responsible for adopting the state building code, which is based on national model codes, including the International Building Code (IBC) and the International Residential Code (IRC). These codes are then adopted by the counties, often with local amendments to address specific regional needs, such as high wind requirements and tropical climate considerations.
Roofing requirements are integrated into these broader building codes. For example, the state-adopted codes include specific provisions for roof coverings, slope, drainage, and high-wind resistance. Because the adoption process involves both the state council and individual county legislative bodies, the specific version of the code in effect can vary by county. Property owners and contractors must consult their local county building department to determine the exact code version and local amendments applicable to their specific project.
The primary agency responsible for setting these standards is the Hawaii State Building Code Council, which is administratively attached to the Department of Accounting and General Services (DAGS). Additionally, the Department of Commerce and Consumer Affairs (DCCA) Contractors License Board oversees the licensing of roofing contractors, ensuring that those performing the work meet professional standards.
