Do I Need a Permit for a Shed in Miami-Dade County?

When a permit is usually required

Sheds in Miami-Dade are commonly permitted because HVHZ wind-load requirements apply to nearly any anchored accessory structure.

• Sheds over the local exempt-size threshold (typically around 100 square feet).
• Any shed anchored to a concrete pad or slab.
• Sheds with electrical service — lights, outlets, or subpanels.
• Sheds located within a required side or rear setback.
• Sheds inside HOA-controlled communities requiring architectural review.
• Sheds on historic properties or in historic districts.
• Sheds intended for habitable use (ADU-style conversions are a separate permit type).

When a permit may not be required

A limited category of small, freestanding, unanchored sheds may fall outside permit requirements in some Miami-Dade jurisdictions.

• Portable, non-anchored sheds under the local exempt-size threshold.
• Simple pop-up storage tents.
• Freestanding storage boxes not fixed to the ground or building.

Miami-Dade / South Florida considerations

Because Miami-Dade requires wind-load compliance for permanent accessory structures, most sheds need engineering and inspection review.

• Wind-load engineering — sheds usually need sealed structural drawings and calculations demonstrating compliance with the local ultimate wind speed.
• Zoning — sheds must respect setbacks and lot-coverage limits set by the parcel's zoning district.
• Product Approval — pre-manufactured sheds often carry Miami-Dade NOA or Florida Product Approval, which simplifies the filing.
• Electrical sub-permit — required for any powered shed.
• HOA approval — many South Florida HOAs require architectural review before installation.

Common mistakes that delay approval

Sheds are one of the most common unpermitted structures found during resale inspections. The typical mistakes are the same across jurisdictions.

• Placing the shed in a required setback without a variance.
• Filing without wind-load engineering for anchored sheds.
• Missing electrical sub-permit for powered sheds.
• Assuming a pre-manufactured shed is exempt when it exceeds the local size limit.
• Not accounting for HOA architectural approval before installation.

Documents usually needed

Shed permit filings vary by size and complexity — the following items are commonly required.

• Building permit application.
• Site plan showing shed location, setbacks, and lot coverage.
• Sealed structural drawings or manufacturer's approval documents.
• Wind-load calculations.
• Electrical sub-permit application when applicable.
• HOA approval letter, when required.
• Zoning variance documentation, when required.
