Wind Mitigation Inspection in Miami-Dade County

Miami-Dade is one of only two Florida counties inside the High-Velocity Hurricane Zone, with its own building code and product-approval system. Here is what that means for your wind mitigation inspection.

Miami-Dade County is one of only two Florida counties, along with Broward, inside the High-Velocity Hurricane Zone (HVHZ), a designation carrying stricter wind-load and product-testing rules than the rest of the state. That distinction shows up directly on your wind mitigation form.

What's different about the form here?

On Question 1 of the OIR-B1-1802 form, Miami-Dade homes have a second compliance path unavailable elsewhere in Florida: the 1994 South Florida Building Code (SFBC-94), with a qualifying permit application dated on or after September 1, 1994. A Miami-Dade home permitted between September 1994 and March 2002 can still hit the strongest code-compliance tier through this HVHZ-specific path, even though it would not qualify under the standard statewide 2001 Florida Building Code path used elsewhere. Roof coverings and shutters are also commonly documented here through a Miami-Dade County Notice of Acceptance (NOA) number rather than a generic statewide product-approval number, since Miami-Dade runs its own product-approval office separate from the state system.

Finding your home's permit history

You will likely need your original building permit date or roofing permit date for the inspector to document Question 1 and Question 2 correctly. Miami-Dade's Property Appraiser site is the starting point for a home's year-built record; permit-specific documentation typically needs a request to the county building department.

What does it cost locally?

Miami-Dade sits in the higher end of Florida's pricing range: $100 to $175 for a standalone wind mitigation inspection, $175 to $275 combined with a 4-point, per the Miami/Fort Lauderdale regional figures at inspectordata.com. See our full statewide cost guide for comparison against other regions.
