Higher SMA Minor Permit Limit and Shoreline Homes: What HB 654 Means for You
Coastal communities in Hawaiʻīi have long had to navigate the Special Management Area (SMA) permitting system. The SMA process exists to protect our beaches, reefs and cultural resources from overdevelopment, but it can also slow down projects and add to costs. House Bill 654 aims to simplify things by doubling the value of projects eligible for a minor permit—from $500,000 to $1 million—and allowing shoreline single-family homes under 7,500 square feet to use the minor-permit path. In this article we explain what’s changing, why it matters and how Shoreline Consulting can help you make sense of it.
What’s a minor SMA permit?
Under current rules, projects valued at $500,000 or less qualify for a minor permit. These permits are handled by county planning staff with limited public hearings, making them faster and cheaper to obtain than major permits. Larger projects or those with potential environmental impacts require a major permit, which involves public hearings, detailed environmental assessments and more agency review. There are also exemptions for low-impact work—like small additions, interior renovations or building two dwellings under 7,500 square feet on non-shoreline lots.
Why adjust the threshold?
The $500,000 limit hasn’t changed in decades, even though construction costs have skyrocketed. Many modest coastal home renovations now exceed that amount, pushing homeowners into the major-permit process. Previous proposals, like House Bill 732, suggested raising the cap to $750,000 but faced criticism from community advocates who worried about reduced public input and environmental oversight. HB 654 takes an even bigger step by proposing a $1 million cap.
What HB 654 proposes
Representative Mark Hashem’s HB 654 would amend Hawaiʻīi Revised Statutes 205A-22. The bill:
- Raises the minor-permit limit from $500,000 to $1,000,000.
- Allows single-family homes under 7,500 square feet on shoreline parcels or parcels susceptible to waves, storm surges, or erosion to qualify as minor permits. These homes must not be part of a larger development and cannot cause a “substantial adverse environmental or ecological effect”.
- Would take effect immediately upon approval.
The bill remains in committee, having been introduced in early 2025 and carried over to the 2026 session. It may be amended before it becomes law.
Potential benefits
Faster approvals for mid-sized projects. Getting a major permit can take nine months or more, whereas minor permits typically resolve within two to six months. By raising the cap, HB 654 could speed up permitting for many small businesses and homeowners.
Reflecting real costs. A $500,000 cap doesn’t reflect today’s construction prices. A $1 million limit acknowledges inflation and prevents routine renovations from triggering major permits.
Encouraging resilience. Some shoreline homeowners need to elevate or relocate structures due to erosion. Allowing these projects under the minor-permit pathway could make climate-resilient improvements more achievable.
Why some are concerned
Less public input. Major permits require public hearings, giving communities a chance to weigh in. Critics worry that shifting more projects to minor permits will cut neighbors and cultural practitioners out of the discussion.
Environmental risks. Coastal areas are already threatened by rising seas, erosion and storms. Without full review, projects could inadvertently worsen erosion or block shoreline access. HB 654 keeps the requirement that minor permits must not have substantial adverse effects, but interpreting that standard can be subjective.
Speculative development. Raising the limit may encourage investors to buy and flip shoreline properties. Community advocates warn that bad actors could understate project costs to avoid the major-permit process.
How Shoreline Consulting can help
Even if HB 654 passes, the SMA process remains complex. Counties still require detailed site plans, narratives and environmental documentation, and projects must comply with multiple regulations—from flood zones to historic preservation. Our team at Shoreline Consulting Hawaiʻīi specializes in navigating these requirements.
- We prepare complete applications that address environmental impacts, drainage, cultural resources and public views.
- We help guide the architectural and design process—like elevating structures or using erosion-resistant materials—that minimize ecological impacts while protecting your investment.
- We engage the community, helping you build goodwill with neighbors and incorporate local knowledge into your plans.
- We stay on top of legislative changes, advising you on how new laws like HB 654 may affect your project timeline and permitting strategy.
Next steps for homeowners
If you’re planning a project near the coast:
- Check if your property is in the SMA using county GIS maps.
- Know the current rules: minor permits are limited to $500,000 projects for now.
- Start planning early. Even minor permits require clear site plans and supporting documents.
- Monitor HB 654 and similar bills to see if rules change.
- Consult experts. Our team can help you understand your options and streamline the process.
Final thoughts
HB 654 would dramatically expand the scope of minor SMA permits by doubling the valuation threshold and including shoreline homes. Proponents say it would save time and reflect real construction costs, while opponents warn about reduced oversight and increased risks. Whatever happens, one thing is clear: building along Hawaiʻīi’s beautiful, fragile coast requires careful planning. Shoreline Consulting Hawaiʻīi is here to help you make sense of evolving rules and bring your vision to life responsibly.
