Miami, FL Accessory Structures: ADU Rental Restrictions (2026)

Miami has a two-tier ADU rental framework. Long-term rentals (30+ days): permitted in all transect zones where ADUs are themselves allowed. The unit must comply with Florida Building Code, Florida residential landlord-tenant law (FL §83), and any Miami-Dade County rental rules — but there is no separate City of Miami long-term rental license. Short-term rentals (less than 30 days): heavily restricted. Miami Code §2-1100 (the city's vacation rental ordinance) prohibits short-term vacation rentals in T3 single-family transect zones (T3-R, T3-L, T3-O) except where the property is the operator's primary residence. In T4, T5, and T6 zones, STRs are allowed with a City Certificate of Use and compliance with parking, occupancy, and registration requirements. Florida Statute §509.032(7) preempts local governments from prohibiting STRs altogether or treating them differently from other residential uses for rental periods of less than 30 days, but municipalities may impose reasonable registration and inspection requirements. Operators must also collect Florida 6% sales tax, Miami-Dade County 3% Tourist Development Tax, and 1% Convention Development Tax. Miami-Dade County also requires a Certificate of Use under Chapter 8A.
