Miami-Dade and Broward counties fall inside Florida's High-Velocity Hurricane Zone (HVHZ), the strictest wind-load building code in the country — roofing, windows, and exterior doors generally must be impact-rated and separately product-approved, which raises material costs compared to the rest of the state.
