Multiple sources report that Maui County adopted a new ordinance, effective July 8, allowing qualifying residentially zoned properties to have up to two accessory dwelling units (ʻohana units) in addition to a primary residence — three units total on one lot. The rule change applies countywide across Maui, Molokaʻi, and Lānaʻi, and was passed in response to the island’s severe housing shortage. Importantly for property owners, the new units are explicitly prohibited from being used as vacation rentals, short-term rentals, or bed-and-breakfast operations.
