Full Breakdown
Miami-Dade County Code Section 33-22(2)(f) governs accessory units on single-family lots in unincorporated Miami-Dade (UMSA): the AU, EU, RU and trended GU zoning districts inside the Urban Development Boundary. An accessory dwelling unit (ADU) may be rented for a fee, but only for stays of one month or longer; shorter stays make it a vacation rental, which Section 33-28 does not allow for an ADU rented apart from the main house. A guesthouse cannot be rented for a fee separately from the principal dwelling, and the owner cannot live in the guesthouse while renting out the house. Neither unit can be sold apart from the property.
Violations & Fines
Renting an unauthorized or unregistered accessory unit, or otherwise violating Section 33-22, draws Code Enforcement fines of $500 for a first offense, $1,000 for a second, and $2,500 for each offense after that, per Section 8CC-10.
