Miami Beach, FL Accessory Structures: Tiny Homes (2026)

Miami Beach allows Accessory Dwelling Units on the same lot as a primary single-family residence in qualifying zoning districts. ADUs may include a full kitchen facility and a separate electric meter. Maximum height for accessory structures is 12 feet for one story and 20 feet for two stories above adjusted grade. ADUs must maintain setbacks appropriate to the residential zoning district and feature architectural design that complements the primary structure to preserve neighborhood character. A streamlined permitting process is available for qualifying ADUs, but applicants must submit site plans and construction documents meeting the Florida Building Code. Due to the High-Velocity Hurricane Zone designation, all ADU construction requires engineering by a licensed Florida PE or architect and materials with Miami-Dade product approval. Tiny homes on wheels (THOWs) are classified as recreational vehicles and cannot serve as permanent residences under Miami-Dade County and Miami Beach zoning codes. Manufactured homes must meet HUD standards and are generally not permitted in most Miami Beach residential zones due to aesthetic and historic preservation requirements.
