RE: Item A(1) — ON ACCESSORY DWELLINGS ON RESIDENTIALLY ZONED LOTS
Aloha Chair Lindo, Vice Chair Sagario and other members of the Commission,
The Grassroot Institute of Hawaii supports Item A(1), which would allow two accessory dwelling units per lot in all of Maui’s County residential zoning districts.
This proposal would be a powerful tool for homeowners and homebuilders to help provide shelter to their friends and family and combat the broader housing crisis.
Currently, many Lana’i and Moloka’i homeowners are prevented from building an ADU at all, unless they brave the costly and time-consuming process of obtaining a special-use permit.
On Lana’i and Moloka’i, a single ADU is allowed on lots that are 7,500 square feet or larger.[1] Many residential lots are smaller than that, which greatly limits the ability of local homeowners to build additional housing on their property.
Meanwhile, on the island of Maui, lots smaller than 7,500 square feet are allowed one ADU, while lots larger than 7,500 square feet can have two.
Grassroot pointed out in its 2023 report “How to facilitate more homebuilding in Hawaii” that allowing more homes on the same lot is a powerful approach that many states and cities across the county have used to increase housing supply.
Such places include Minneapolis, Minnesota; Houston, Texas; Milwaukee, Wisconsin; and Columbus, Ohio; as well as the entire states of California and Montana.[2] Auckland, New Zealand, is a good international example.[3]
All of those jurisdictions “upzoned” residential areas to allow greater housing density on land already zoned for housing — and research indicates these changes have helped moderate or reduce housing prices.[4]
There are other advantages to promoting smaller homes. For instance, focusing on “infill” development — building homes within existing residentially zoned areas — would help alleviate concerns related to infrastructure because existing residential areas typically have more water and wastewater infrastructure available.
Legalizing more homes in existing residential areas also appears to be in line with the 2018 Moloka’i Island Community Plan, which states in its “Land Use Planning Principles and Standards” that “Moloka’i’s small towns should provide a mix of housing types and affordability, compact and pedestrian-oriented development, access to parks and open space, and a mix of compatible and complementary land uses.
“Future growth areas will be contiguous or proximate to existing employment and/or housing, and located where infrastructure and public facilities can be provided in a cost-effective manner.”[5]
This draft bill would also put the county into compliance with the state’s Act 39 (2024), which requires the counties to allow two ADUs per lot in residential zones by Dec. 31, 2026.
Thank you for the opportunity to testify.
