  • Miami-Dade NOA or Florida Product Approval documentation for the pre-fabricated shed system or for wind-critical structural components used in site-built sheds.
  • Foundation and anchorage details showing how the shed is anchored to resist 175 mph wind uplift and lateral loads — required for all permitted sheds and recommended for permit-exempt sheds.

Process

How the permit process works

  1. Apply the 200-square-foot FBC exemption as the first filter Under FBC Section 105.2, a one-story shed at 200 square feet or less may be exempt from the City of Miami building permit requirement. Larger sheds, masonry sheds, and any shed with utility work require a permit. Even exempt-sized sheds must comply with Miami 21 zoning setbacks and HVHZ wind resistance standards.
  2. Verify Miami 21 zoning placement before buying or ordering Use the City of Miami GIS at gis.miamigov.com to confirm the parcel's Miami 21 transect zone. Setbacks, height limits, and maximum accessory structure footprint vary by zone. Confirm the shed placement complies with Miami 21 before ordering a prefab unit or pouring a foundation.
  3. Confirm HVHZ compliance for the shed product For pre-fabricated sheds, verify the product has a current Miami-Dade NOA or Florida Product Approval covering the structural system and wind anchorage. Search the NOA database at miamidade.gov/permits/product-approval. For site-built sheds over 200 sq ft, engage a Florida PE to prepare HVHZ-compliant structural drawings.
  4. Identify utility scope and trade permit needs Decide whether the shed will have electrical, plumbing, or mechanical work. Each utility trade requires a separate City of Miami permit and inspection regardless of whether the shed's footprint is permit-exempt.
  5. Submit through iBuild for permitted sheds For sheds requiring a permit, apply through the City of Miami iBuild portal at miamigov.com. Upload the site plan, structural drawings (PE-sealed for HVHZ), NOA documentation, and Miami 21 compliance documentation.
  6. Clear plan review comments and pay fees Miami plan reviewers check structural, Miami 21 zoning, HVHZ product approval, and FBC compliance. Respond to comments and resubmit. After approval, pay fees through iBuild. Record the Notice of Commencement before starting construction.
  7. Build and complete required inspections Request inspections through iBuild. Typical shed permit inspections include a foundation/slab inspection, framing or structural inspection, and final. Trade permit inspections are scheduled separately.

Code basis

What Miami reviews against

Florida Building Code (FBC) 8th Edition (2023) Section 105.2 (permit exemption for sheds not exceeding 200 sq ft) and Chapter 16 High Velocity Hurricane Zone (HVHZ) structural provisions; City of Miami Miami 21 Zoning Code (accessory structure setbacks and placement by transect zone); Miami-Dade County NOA and Florida Product Approval requirements for HVHZ-rated construction materials.

What can go wrong

  • City of Miami can issue a stop-work order and require removal of an unpermitted shed that exceeded the FBC size exemption.
  • A shed not anchored to HVHZ standards in Miami-Dade poses a genuine structural safety risk during hurricane events and can become a wind-borne debris hazard.
  • Unpermitted electrical work in or to a shed creates fire and shock hazards that go unverified without Building Department trade inspections.
  • Miami-Dade can place a code lien on the property for unresolved permit violations.
  • Florida homeowners insurance carriers routinely check for permits; wind-mitigation credits depend on verified HVHZ-compliant construction.
  • Unpermitted work must be disclosed in Florida real estate transactions and can delay or derail a sale.

FAQ

Common Miami shed permit questions

Do I need a permit to build a shed in Miami, FL?

It depends on size. Under Florida Building Code Section 105.2, a one-story storage or tool shed with a floor area not exceeding 200 square feet may be exempt from the City of Miami building permit requirement. Sheds over 200 sq ft, masonry sheds, and any shed with electrical or plumbing work require a building or trade permit. All sheds in Miami-Dade — permitted or not — should comply with High Velocity Hurricane Zone (HVHZ) wind resistance standards.

What is the largest shed I can build without a permit in Miami?

The Florida Building Code 105.2 exemption threshold is 200 square feet for a one-story detached accessory structure. That limit applies in the City of Miami. Keep in mind: the building-permit exemption does not exempt you from Miami 21 zoning setbacks, HVHZ wind resistance requirements, or utility trade permits if you add electrical, plumbing, or mechanical work.

Does my Miami shed need to be rated for hurricane winds?

Yes. All of Miami-Dade is in the High Velocity Hurricane Zone. Even sheds that are permit-exempt under the FBC 200 sq ft threshold should be designed or selected to withstand 175 mph design wind speeds and be properly anchored to resist uplift. For pre-fab sheds, look for products with a valid Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval.

What is a Miami-Dade NOA and why does it matter for a prefab shed?

A Notice of Acceptance (NOA) is Miami-Dade County's product approval certifying that a building product meets HVHZ wind and structural requirements. Pre-fabricated shed systems placed in Miami-Dade should have a current NOA covering the structural assembly and wind anchorage. Search the NOA database at miamidade.gov/permits/product-approval before purchasing.

Does adding electricity to my Miami shed require a permit?

Yes. Adding wiring, outlets, lighting, or a subpanel to a shed requires a separate City of Miami electrical permit and inspection, even when the shed itself is 200 square feet or under and otherwise exempt from the building permit requirement.

How much does a Miami shed permit cost?

For a shed requiring a City of Miami building permit, expect roughly $300–$850 in combined permit and plan review fees, plus a 1.5% Florida state surcharge. Sheds within the 200 sq ft exemption with no utility work incur no building permit fee. Verify current rates through the City of Miami iBuild portal at miamigov.com.
