Mayor Mitch Roth Signs Ohana (ADU) Bill into Legislation

In a bid to alleviate the ongoing housing crisis, Hawaii County has taken a bold step forward with the signing of Bill 123. This new measure, endorsed by Mayor Mitch Roth, opens up opportunities for homeowners across the county to build up to three accessory dwelling units (ADUs) on their properties, making it easier for local families to find housing while maximizing the use of existing land.

"I commend Mayor Mitch Roth for his commitment to affordable housing and innovative approaches to help keep our families rooted here in Hawaii. If we can pause Bill 121 until the economic impact study is complete, the Big Island will truly shine as a leader in smart growth and community well-being."

The bill, crafted with input from key figures within the county's Planning Department and County Council members, represents a significant policy shift from previous limitations on 'ohana dwellings. These changes offer a more adaptable approach to expanding housing availability across the county.

“We need to think beyond conventional solutions if we’re serious about tackling our housing shortage,” Mayor Roth said during the bill’s signing. “By enabling more accessory units, we’re allowing homeowners to help meet the demand for housing while ensuring our communities stay strong for future generations.”

What Does Bill 123 Do?

Under the new law, homeowners can now construct up to three ADUs on their property, with each unit capped at 1,250 square feet. Whether detached or attached to the main home, these ADUs are allowed in several zoning districts, including residential, duplex, and agricultural zones.

Key provisions include: Link to Bill 123

• Increased ADU Limits: Homeowners can build up to three ADUs on properties in various zoning districts, including residential (RS), duplex (RD), residential-agricultural (RA), agricultural (A), and family agricultural (FA) districts.
• Limit on Short-Term Rentals: The bill restricts the use of ADUs as vacation rentals, except in a few cases, to prioritize long-term housing solutions.
• Meeting Safety and Infrastructure Standards: Homeowners must comply with existing requirements for water supply, sewage systems, and fire protection when adding ADUs to their properties.

Mayor Roth highlighted the practical benefits of the legislation, emphasizing the need for local solutions to a statewide issue. “By allowing for more ADUs, we’re empowering residents to contribute to the solution. This isn’t just about more homes; it’s about creating sustainable growth and making sure our communities remain livable for the long term.”

Bill 123 arrives at a critical time, offering homeowners a new way to help ease the island's housing pressures while generating potential rental income.
