All districts
Port St. Lucie's citywide Definitions chapter (Sec. 153.01, most recently amended by Ord. Nos. 24-82, 25-06, and 25-24, all adopted in 2025) now defines "ACCESSORY DWELLING UNIT (ADU)" as a secondary housing unit on the same parcel as a primary dwelling, with its own bathroom, kitchen, and separate exterior entrance, and expressly distinguishes it from a guest house. However, no residential district's own use table (Secs. 158.071 through 158.081, covering RE, RS-1 through RS-3, RM-5 through RM-15, and RMH) lists ADU as a permitted or special exception use, and Sec. 158.217 (Accessory Uses and Structures) does not include an ADU among the accessory uses allowed in the single-family districts. This gap coincides with Florida Statute 163.31771 (as strengthened by 2025's SB-48), which required municipalities to adopt ordinances allowing ADUs in single-family zones by December 1, 2025, and bars a blanket ban, a size cap below 1,000 square feet, or an owner-occupancy requirement. This pack's source (codified through Ord. No. 25-68, adopted November 24, 2025) predates that deadline by about one week; the City appears to have added the ADU definition as a first step but had not yet amended the district use tables to operationalize it as of this fetch. Confirm directly with the Planning and Zoning Department whether an ADU-enabling amendment has since been adopted (it should exist under state law by December 1, 2025) before assuming ADUs are unavailable.
