Miami-Dade County Code Section 33-20(k) allows one utility shed up to a maximum of 400 square feet per residential lot. For utility sheds not exceeding 100 square feet in the RU-1 district, setbacks are: 55 feet from the front, 5 feet from rear, 5 feet from interior side, and 10 feet from side street. Rear and interior side setbacks may be reduced to 2 feet with a notarized affidavit of consent from the abutting property owner. No permit is issued for an accessory building unless the principal building already exists on the lot, or permits for both are obtained simultaneously. All sheds must meet Florida Building Code wind load standards for the HVHZ. Tie-downs and anchoring are required even for smaller structures due to hurricane risk.
Unpermitted sheds must be removed or retroactively permitted. Non-compliant setbacks require relocation. HVHZ non-compliance requires anchoring retrofits. Penalties under Chapter 8CC.
