St. Petersburg, FL
ADUs are one of the fastest-growing housing types in the country — but every city has different rules for setbacks, size limits, and parking. State laws increasingly require cities to approve compliant ADUs ministerially, but you still need to meet local zoning requirements for the primary structure and overall site. A single code miss can delay your permit by weeks.
Florida's Live Local Act (SB 102, 2023) requires all cities and counties to allow ADUs on single-family lots with administrative approval. This is a major shift — local governments can no longer prohibit ADUs in residential zones. However, cities still control size limits, setbacks, and design standards.
