Accessory Structures in Coral Gables, FL: What Residents Actually Need to Know

Coral Gables maintains 107 local ordinances across all categories, and 5 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Coral Gables falls on the strict-to-permissive spectrum compared to other cities.

Tiny Homes

Tiny homes are effectively prohibited as standalone dwelling units in Coral Gables residential districts. The city's strict zoning code, minimum lot and building size requirements, and Board of Architects aesthetic review standards create significant barriers to tiny home construction. Accessory dwelling units are regulated separately under the ADU provisions of the zoning code.

Key details: Standalone Tiny Homes: Effectively not permitted. Tiny Homes on Wheels: Classified as RVs, not dwellings. Board of Architects: Design review required for all homes. ADU Alternative: Permitted under ADU regulations. Minimum Standards: Must meet FBC and HVHZ codes.

Placing an unpermitted tiny home or recreational vehicle as a dwelling unit on a residential lot may result in Code Enforcement citations with fines starting at $250 per day. The city may require removal of the structure and issue daily fines until compliance is achieved.

This is one of the stricter rules in Coral Gables's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
