Sheds, workshops, garden structures, and other detached buildings are common on South Florida residential properties, but the permit rules vary significantly between jurisdictions. Even small structures can trigger permit requirements when located in flood zones, exceed defined size thresholds, or include electrical or plumbing systems.
This guide clarifies shed and detached structure permit requirements across Miami-Dade, Broward, and Palm Beach Counties, including the hurricane compliance considerations specific to South Florida.
WHEN SHED PERMITS ARE REQUIRED
Shed permit thresholds vary by jurisdiction: Miami-Dade County typically requires permits for sheds over 100 square feet, Broward County varies by municipality with 100-150 sq ft thresholds common, and Palm Beach County typically requires permits for sheds over 120 square feet. All structures with electrical service require permits regardless of size. All structures with plumbing require permits. Structures in flood zones, coastal construction control lines, or environmentally sensitive areas typically require permits regardless of size.
PRE-FAB VS SITE-BUILT SHEDS
Pre-fabricated sheds (Tuff Shed, Lifetime, plastic resin sheds) sold at home improvement stores may still require permits based on size and installation method. Anchoring requirements apply to all sheds in South Florida regardless of construction type due to hurricane wind loads. Pre-fab sheds delivered as a complete unit must still comply with setback requirements, zoning rules, and HOA approvals. Some manufacturers provide engineering documentation; others require third-party engineering.
SETBACK AND ZONING REQUIREMENTS
Detached structure setbacks vary by zoning category but typical requirements include 5 to 10 feet from property lines (often less for accessory structures than primary structures), proper rear yard and side yard setbacks, height limitations (typically 12-15 feet for residential accessory structures), maximum lot coverage limits that include all structures, and prohibition on structures in front yards in most residential zones. Corner lots, waterfront lots, and lots in special flood hazard areas have additional restrictions.
HURRICANE WIND LOAD REQUIREMENTS
South Florida hurricane wind loads apply to all detached structures: HVHZ areas require structures rated for 175 mph wind speeds, non-HVHZ areas typically 165 mph, structural anchoring to concrete pad or ground anchors with engineered hold-down values, roof material rating for the design wind speed, and proper fastening schedule for wall sheathing and roof decking. Pre-fab sheds without documented hurricane rating may not pass inspection in HVHZ areas.
TYPICAL PERMIT COSTS
Shed permit costs in Miami-Dade County typically run $150 to $600 depending on size and complexity. Broward County runs $125 to $500. Palm Beach County runs $175 to $700. Electrical permits for shed lighting and outlets add $166 minimum. Engineering review for larger or custom structures adds $300 to $1,500. Permits in flood zones or coastal construction control lines cost more due to additional review requirements.
APPROVAL TIMELINES
Shed permits typically process within 5 to 14 business days in Miami-Dade County for pre-fab sheds with manufacturer engineering. Custom or site-built sheds run 2 to 6 weeks. Broward County runs 5 to 12 business days for pre-fab, 2 to 5 weeks for custom. Palm Beach County runs 7 to 18 business days for pre-fab, 3 to 8 weeks for custom. Projects in coastal construction control lines or environmental zones extend timelines.
ELECTRICAL AND PLUMBING ADDITIONS
Adding electrical or plumbing to a shed triggers additional permits: electrical permits for power supply (typically requires GFCI protected circuit run from main service), plumbing permits if water supply or drainage is added, gas permits if natural gas service is extended, and HVAC permits if conditioning is added. These additions often double the total permit cost and timeline. Workshop and home office sheds frequently require all four trades.
POOL HOUSE AND CABANA CONSIDERATIONS
Pool houses and cabanas, while functionally similar to sheds, are classified differently in most South Florida jurisdictions. They typically require full building permits regardless of size, must comply with pool barrier requirements, often require habitable space code compliance (egress, ventilation), and may be limited in square footage based on accessory dwelling unit rules. Pool house permits run $500 to $2,500 for typical residential applications.
