The Current Fragmented System

Hawaii doesn’t have one building code—we have four. Each county tweaks and updates their own on different timelines, creating a chaotic landscape for development.

Redesign Costs

Architects and engineers must redesign projects on a county-by-county basis, adding significant delays and unnecessary costs to every home.

Inconsistency

A house legal on Maui might be illegal on Oahu due to conflicting rules. This inconsistency confuses builders and inspectors alike.

Supply Barrier

Fragmented rules act as a bottleneck, reducing the statewide housing supply by making simple projects slower and more expensive to approve.

See Why It Matters

Triplexes and fourplexes are often treated like commercial apartment buildings, adding tens of thousands in unnecessary costs for features that aren't required for safety.

  • Lower Construction Costs

    Make housing more affordable by removing redundant regulations.

  • Uniform Safety Standards

    Maintain high safety without confusion across county lines.

PROPOSED LEGISLATION

The Solution: HB1725

This bill creates a single, sensible statewide building code that applies consistently across all counties, ending the patchwork system.

1

Residential Standards

Classifies triplexes and fourplexes under the International Residential Code.

2

Safety First

Ensures common-sense fire safety without cost-prohibitive commercial requirements.

Frequently Asked Questions

Would this bill make multifamily homes less safe?

No. The International Residential Code requires strict fire-safety protections such as fire-rated walls, egress points, and smoke alarms. It's built for safety.

What is so bad about requiring fire sprinklers?

Fire sprinklers dramatically increase costs (often tens of thousands of dollars) and are not required for similar residential buildings (single family homes) under the International Residential Code.

Would the counties lose all control?

No. Counties can adopt targeted amendments to address local needs, but the baseline code would remain consistent statewide to ensure predictability.

Are other states doing this?

Yes. States like North Carolina and Utah use the Residential Code for up to four units, recognizing them as small residential buildings rather than commercial structures.
