This ordinance, identified as BL2025-598, amends Chapters 17.04 and 17.16.030 of the Metropolitan Code of Laws for Nashville and Davidson County. The primary change allows for Attached Accessory Dwelling Units (AADUs) in several mixed-use and urban zoning districts, specifically MUL, MUN, MUNA, MUN-A, MUG, and MUG-A. Concurrently, Section 17.16.030, which outlines permitted uses in residential zoning districts, is also amended to reflect and integrate these new AADU allowances. This legislative update aims to enhance housing flexibility and increase density within already developed areas of the metropolitan government's jurisdiction.
