ADU rules in Coral Gables, FL — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Coral Gables strictly regulates accessory dwelling units through its Zoning Code and Board of Architects review. ADUs are limited to ancillary apartments in select residential zoning districts with significant size, design, and owner-occupancy requirements enforced by Development Services.
The City of Coral Gables permits ancillary apartments (the local term for ADUs) in certain single-family residential zoning districts under the Zoning Code. Ancillary apartments must be subordinate to the principal dwelling and cannot exceed specific size limits established by the zoning district. All ADU proposals require Board of Architects approval for design compatibility with the neighborhood character and Mediterranean architectural standards. ADUs must comply with setback requirements for the applicable zoning district, maintain adequate parking, and meet all Florida Building Code requirements including HVHZ wind load standards. Owner occupancy of either the primary residence or the ADU is required. ADUs cannot be used as short-term rentals. A building permit is required from Development Services at (305) 460-5235, and projects must go through site plan review.
Unpermitted ADUs are subject to code enforcement action at (305) 460-5216, including violation notices, daily fines, and mandatory removal orders. Converting structures without permits creates liability for unpermitted construction and zoning violations.
