Hawaii Remodeler Legislation, Codes, and Guidelines

Hawaii State Building Codes and Legislation for Remodelers and Residential Renovations

Hawaii's building codes are established at the state level and then adopted and potentially amended by each of the four counties. The State Building Code Council is the primary body responsible for adopting these standards. Currently, Hawaii has adopted the 2018 International Building Code (IBC), the 2018 International Residential Code (IRC), the 2018 International Existing Building Code (IEBC), and the 2021 International Energy Conservation Code (IECC). [2, 7, 10, 11, 21, 22] The state code is based on these International Code Council (ICC) models, with state-specific amendments. Counties then have a period to adopt and amend these state codes for their jurisdictions. [3, 7, 10, 25]

1. Specific State Statutes and Codes Adopted

Hawaii has adopted the following key codes:

It's important to note that the adoption process can be complex and sometimes delayed, with counties having their own timelines for adopting state-approved codes. [3, 25]

2. Primary State Board or Agencies

The primary state-level body responsible for setting and adopting building standards is the State Building Code Council (SBCC). [2, 3, 7, 10, 11, 25, 27] Each county also has its own building department that issues permits and enforces codes at the local level. For example, the Department of Planning and Permitting (DPP) handles permitting in Honolulu. [13, 18, 20, 23, 24]

3. Classification of Remodels and Demolition Guidelines

Generally, permits are required for any project that involves:

Minor cosmetic remodels, such as painting or replacing fixtures, typically do not require a permit, unless they exceed certain valuation thresholds or involve electrical/plumbing work. [16, 24]

Converting attics or basements to habitable living spaces would generally be considered a structural alteration and require a permit. [4]

Demolition guidelines are also in place. A demolition permit is typically required for any demolition project. [13, 18, 20] Specific regulations exist for the handling of hazardous materials, such as asbestos, during demolition and renovation activities. [17, 26] A thorough inspection for asbestos is required before demolition or renovation begins. [17]
