What's Required in Miami
- All sheds must be engineered for High Velocity Hurricane Zone (HVHZ) wind loads (175+ mph).
- Must be anchored to a concrete slab or approved tie-down system per FBC 105.1.
- Must maintain 5-foot setbacks from side and rear property lines in residential zones.
- Property survey showing the intended shed location is mandatory for all applications.
- Materials must have a valid Florida Product Approval or Miami-Dade NOA (Notice of Acceptance).
- Maximum height is generally limited to 10 feet for accessory storage structures.
What Size Shed Needs a Permit in Miami
Whether you need a building permit for a shed in Miami usually comes down to size. Most cities exempt small accessory structures — commonly those under about 120 to 200 square feet — and require a permit for anything larger; Miami’s exact cutoff is set by the City of Miami Building Department, so check the size threshold in the requirements above before you build. A popular 10x12 shed (120 sq ft) sits right at that common dividing line, so it’s worth confirming. Larger sheds, and any shed with electrical, plumbing, or a permanent foundation, almost always need a permit regardless of footprint.
Building a Shed Without a Permit in Miami
Even when a shed is small enough to skip a building permit in Miami, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay under the City of Miami Building Department’s size threshold, sit on a non-permanent base (sheds on skids or a gravel pad are treated more leniently than those on a poured foundation), and have no electrical or plumbing run to it. Crucially, zoning setbacks still apply — your shed usually has to sit a minimum distance from property lines and other structures, and that holds even for a permit-free shed. Confirm both the size exemption and the setback distance with the City of Miami Building Department before you build.
