Metal Building Permits in Florida: What You Actually Need
Permit requirements for steel structures vary widely across Florida — what's required in Hillsborough County may be different from Polk County, and what applies to an open carport is completely different from what applies to an enclosed garage. This guide walks through the general framework most Florida homeowners will encounter, and explains what to ask your county before you order.
The Basic Rule: Size and Enclosure
Most Florida counties base permit requirements on two factors: the total square footage of the structure and whether it's enclosed (has walls) or open.
Generally speaking: - Open structures under 200 sq ft (like a small carport): often permit-exempt or require only a zoning review - Open structures over 200 sq ft: typically require a permit with basic engineering - Any enclosed structure: almost always requires a permit regardless of size
These thresholds vary. Some counties start requiring permits at 100 sq ft. Some coastal counties require permits on anything that requires anchoring. Always confirm with your local building department before ordering.
Wind Load Certification
Florida has some of the strictest wind-load requirements in the country — and for good reason. Every permitted structure in Florida needs to meet the wind speed requirements for its location.
Most of Florida falls under a 130–160 mph wind zone depending on where you are. Coastal areas and South Florida have higher requirements. When you order a steel building from us, we'll provide a certified engineer's letter with the wind-load specs for your structure. This is what your building department will want to see.
If a dealer can't provide an engineer letter or engineer-certified drawings, walk away. That building is not designed to meet Florida code.
Setback Requirements
Setbacks are the required minimum distances from your property lines. Your county's zoning or land development code will specify how far back a structure must be from: - The front property line - The side property lines - The rear property line - Any easements or rights-of-way
Setback rules also vary by the type of structure — a detached garage usually has different setback requirements than an open carport. Some HOAs have additional restrictions on top of county requirements. Check your deed and any HOA docs before you finalize placement.
A survey of your property is extremely helpful here. If you don't have one, your county property appraiser's office usually has a GIS map online that shows approximate property boundaries.
The Permit Process Step by Step
Here's a typical sequence for a permitted steel structure in Florida:
1. Submit permit application to your county building department with site plan showing structure placement and setbacks 2. Provide engineer-certified drawings — we supply these for all our permitted builds 3. Building department review — typically 2–6 weeks depending on your county 4. Permit issued — you'll get a permit number and inspection requirements 5. Structure installed — our crew installs with your permit posted on site 6. Final inspection — a county inspector comes out and signs off
Some counties have an expedited review process. Some allow online submission. Call your local building department and ask — they're usually helpful.
What About Unpermitted Structures?
It's tempting to skip the permit process, and many small structures go up without permits every year. The risks:
- Insurance: your homeowner's insurance may not cover an unpermitted structure or anything inside it - Sale of property: unpermitted structures can complicate a home sale and may need to be removed or retroactively permitted - County enforcement: some counties actively cite unpermitted structures, especially in response to neighbor complaints - Wind events: if a structure fails and damages adjacent property, lack of a permit can create significant liability
For most customers with a structure over 200 sq ft, we recommend going through the permit process. It protects your investment.
We pull permits for customers across Florida regularly. If you need guidance on what your county requires, give us a call at (863) 296-3400 and we can point you in the right direction.
Permits aren't complicated when you know what to ask for. Once you know your county's requirements, getting a permitted steel building installed is a straightforward process.
