 Maui's Evelyn Del Valle testified this week in support of that change. Maui Mayor Richard Bisson has proposed an ordinance that would phase out about half of Maui's nearly 14,000 vacation rental units in apartment-zoned districts. The Maui Planning Commission meeting this week was the first step in the process of what Bisson says would create more housing for Maui residents. University of Hawaii's Economic Research Organization backs that claim.
