Full Breakdown
To legally rent an ancillary dwelling unit (ADU) in Miami, the owner must obtain an approved building permit with a notarized owner disclosure statement, an approved certificate of occupancy, and an ADU registration certificate from the office of zoning, then renew that certificate annually with a virtual or in-person compliance inspection. The property must carry a homestead exemption, and the ADU can only be used as predominately permanent housing: renting it as transient or temporary lodging is grounds for denial or revocation. Initial registration and inspection costs $300, annual renewal $250, and renting without a certificate doubles the fee exposure.
Violations & Fines
Renting an unregistered ADU, losing homestead status while still renting, or using the ADU for transient or temporary lodging can mean registration denial or revocation, double fees, and enforcement under chapter 2, article X of the City Code.
