In unincorporated Hillsborough County, sheds under 150 sq ft are exempt from a building permit — but all sheds in Florida must still meet hurricane wind load and anchoring requirements. In the City of Tampa, the exemption is slightly smaller (120 sq ft). For sheds over 150 sq ft in the county, a full permit with engineered plans and inspections is required.
Florida Is Different: Wind Code Applies to Every Shed
Florida's statewide building code — the Florida Building Code (FBC) — is one of the most hurricane-focused building standards in the country. Even when a shed is small enough to be exempt from a building permit, it must still meet Florida's wind resistance and anchoring requirements. In Hillsborough County's wind zone, sheds are designed for wind speeds of approximately 130–140 mph, depending on your specific location and proximity to the coast.
What this means practically: a standard big-box shed from Home Depot or Costco may not meet Florida's wind requirements without proper anchoring. The permit process for larger sheds includes engineering review that verifies wind resistance — which is one reason it's more involved in Florida than in most other states.
The Jurisdiction Question: Unincorporated County vs. City of Tampa
Hillsborough County contains several incorporated cities — Tampa, Temple Terrace, and Plant City — each with their own building departments. The Hillsborough County Development Services department covers only unincorporated areas. Most suburban and rural properties in the county outside these cities fall under county jurisdiction.
If your address is in Tampa, apply through the City of Tampa's permitting portal. If outside Tampa, Temple Terrace, or Plant City, apply through Hillsborough County Development Services (HillsGovHub).
Permit Rules: Unincorporated Hillsborough County
| Shed Size | Permit Required? | Notes |
|---|---|---|
| Under 150 sq ft, no utilities | NO BUILDING PERMIT | Exempt per Hillsborough County rules. Must still meet setbacks, wind anchoring, and zoning requirements. |
| 150 sq ft or over | YES | Full permit required through HillsGovHub. Engineering plans required, signed and sealed by a Florida-registered architect or engineer. |
| Any shed with electricity | YES | Electrical permit required separately from building permit. |
| In Special Flood Hazard Area (SFHA) | YES | Additional flood zone documentation required. All structures in the SFHA require full compliance review. |
| Intermodal shipping container shed | YES | Must comply with Hillsborough County ISC Sufficiency Guidelines — separate requirements apply. |
Permit Rules: City of Tampa
| Shed Size | Permit Required? | Notes |
|---|---|---|
| Under 120 sq ft, no utilities, one story | NO BUILDING PERMIT | Exempt per Tampa's local FBC amendment. Setbacks and wind anchoring still apply. |
| 120 sq ft or over | YES | Permit through City of Tampa Construction Services. Engineered plans required for larger structures. |
| Any shed with utilities | YES | Separate trade permits required for electrical, plumbing, mechanical. |
The Florida Wind Code: What It Means for Your Shed
Even for permit-exempt sheds in Hillsborough County (under 150 sq ft), Florida's wind code requirements still apply. Here's what that means in practice:
- Anchoring: Sheds must be anchored to the ground in a way that meets wind resistance requirements. This typically means anchor straps or helical tie-down anchors driven into the ground, connected to the shed's floor frame. A shed sitting on concrete blocks without anchoring does not meet Florida's standard.
- Engineered anchoring plans: For permitted sheds (over 150 sq ft in the county), your engineer must specify the anchoring system in the plans. Pre-manufactured shed manufacturers sometimes provide pre-engineered anchor systems — check whether your shed model has a Florida Product Approval (FPA) number, which simplifies the engineering requirement.
- Wind speed design: Hillsborough County's basic wind speed is approximately 130 mph (Risk Category II per ASCE 7). Coastal portions of the county may be higher. Your shed's structural system must be designed for this wind speed.
Setback Requirements — Hillsborough County
- Side and rear property lines: Typically 5 feet minimum in residential zones (verify with Development Services for your specific zoning district)
- Front yard: Sheds not permitted in front yards in residential zones
- Easements: No structures permitted over drainage, utility, or access easements
- Septic systems and drain fields: Sheds cannot be placed over or immediately adjacent to a septic system or its repair area
- Trees: Any tree 12 inches or larger in diameter that must be removed for shed placement requires a separate tree removal permit from Hillsborough County
- Flood zones: Properties in FEMA flood zones have additional elevation and setback requirements
How to Apply: Hillsborough County (Over 150 Sq Ft)
- Confirm jurisdiction — verify your property is in unincorporated Hillsborough County (not Tampa, Temple Terrace, or Plant City)
- Obtain engineered plans — for sheds over 150 sq ft, digitally signed and sealed plans from a Florida-registered architect or engineer are required. Alternatively, use a pre-manufactured shed with a current Florida Product Approval number.
- Prepare your site plan — draw to scale showing property lines, all existing structures, proposed shed location, dimensions, and setback distances from all property lines
- Check for trees — if any trees 12 inches or larger in diameter are in the work area, apply for a tree removal permit through HillsGovHub
- Apply online through HillsGovHub at hcfl.gov/businesses/hillsgovhub — upload all required documents digitally
- Notice of Commencement — a recorded certified copy is required prior to the first inspection (Florida Statute 713.13)
- Pay fees — Hillsborough County calculates fees based on occupancy, square footage, and work type; includes a $50 application fee plus plan review (50%) and inspection (50%) components. Expect $150–$500+ for most residential shed permits.
- Schedule inspections — foundation/anchoring inspection before shed is placed; final inspection after installation is complete
What Is a Notice of Commencement and Why Does It Matter?
Florida Statute 713.13 requires a Notice of Commencement (NOC) for most permitted construction projects. The NOC is a legal document that provides public notice of construction and protects homeowners from liens by contractors and subcontractors. You must file the NOC with the Hillsborough County Clerk of Court, record it, and provide a certified copy to the building department before your first inspection will be scheduled. If you're acting as your own contractor, the process is straightforward — but it's an extra step that many homeowners don't know about until their first inspection gets rejected.

HOA Rules Are Very Common in the Tampa Metro
Hillsborough County has one of the highest HOA penetration rates of any Florida county. Many communities in Brandon, Riverview, Valrico, Westchase, South Tampa, and New Tampa have active HOAs with specific shed restrictions. Common rules include:
- Prohibition on visible metal or plastic sheds from the street or from neighboring properties' rear yards
- Requirements for matching materials to the home (wood construction only, for example)
- Height restrictions (typically 8 feet maximum)
- Architectural review board approval required before ordering
- Placement restrictions (rear yard only, specific setback from rear fence)
Get HOA approval in writing before ordering your shed and before applying for a county permit.
