Bill Summary · HB 659

Legislative bill overview

HB 659 updates Hawaii's building codes to strengthen hurricane-resistant construction criteria for structures in the state. The bill was introduced in January 2025 and has been referred to multiple committees (Public Business Services, Housing, and Finance) for review. It was carried over to the 2026 regular session, meaning it did not complete the legislative process in 2025.

Why is this important

Hawaii faces significant hurricane risk, and building code standards directly affect public safety, property protection, and insurance costs for residents. Strengthening hurricane-resistant criteria could reduce damage from future storms, potentially saving lives and reducing economic losses. However, stricter building codes typically increase construction costs, which may affect housing affordability and development expenses.

Potential points of contention

  • Construction cost increases: More stringent hurricane-resistant requirements will likely raise building and renovation costs, potentially affecting housing affordability and development feasibility
  • Retrofit requirements and existing structures: Unclear whether the bill mandates upgrades to existing buildings, which could burden current property owners with expensive compliance costs
  • Economic competitiveness: Stricter standards may make Hawaii less competitive for new development or business relocation compared to other jurisdictions with less rigorous codes
