This bill amends Jacksonville's Ordinance Code to establish a comprehensive "Missing Middle Housing" zoning overlay within Chapter 656, Part 3. The initiative aims to diversify housing options, including duplexes, triplexes, quadplexes, and accessory dwelling units (ADUs), to address the city's affordable and attainable housing shortage. Concurrently, the bill amends Chapter 656, Parts 18 and 19 to create a Residential Redevelopment Trust Fund and adjust the Economic Development Expenditure Policy, providing financial mechanisms to support the Missing Middle Housing program. These changes are designed to encourage infill development and increase housing supply across existing neighborhoods.
