Summary
Miami 21 caps residential driveways at 20 feet wide in the First Layer, with tighter limits on narrow lots and in T3-O.
Driveways within a Lot shall comply with the following standards: Driveway Widths The maximum width of a driveway in the First Layer shall be twenty (20) feet and the minimum width shall be ten (10) feet. In T3-R and T3-L, on Frontages less than forty-five (45) feet, driveway width(s) in the First Layer shall not exceed thirty percent (30%) of the length of the Frontage but in no case shall it be less than ten (10) feet. In T3-O, driveway width(s) shall be limited to twenty (20) feet in aggregate per Frontage. In T3-O, where an existing legal Building prevents the required parking from being placed in the Second Layer, the aggregate driveway width may be increased up to a maximum of forty (40) feet. Said driveway shall utilize parking strips not to exceed two (2) feet in width. Driveway Separation T3-R and T3-L, driveways on a Frontage shall have a minimum separation distance of forty percent (40%) of the length of that Frontage. In T3-O, there shall be no driveway separation requirement. Tandem Parking on site is encouraged. For Lots with one or more residential Buildings, there shall be no limitation on the number of vehicles placed behind one another. No vehicle shall be placed above another unless internalized in a fully screened garage.

Full Breakdown
Miami 21, the city's form-based zoning code, regulates driveways by Transect Zone rather than a single citywide rule. In the T3 Sub-Urban zone, a driveway in the First Layer (the yard nearest the street) can be at most 20 feet wide and must be at least 10 feet wide. On T3-R and T3-L frontages under 45 feet, driveway width in the First Layer is further capped at 30% of the frontage length, never less than 10 feet. T3-R and T3-L driveways sharing a frontage must also keep a minimum separation of 40% of the frontage length. Each Transect Zone (T3 through T6) carries its own version of these standards in Article 5.
Violations & Fines
Building or widening a driveway beyond these limits without an approved plan is a zoning code violation, enforced through the city's code enforcement and building permit review process rather than a fixed fine schedule.
