Miami-Dade County Code Chapter 8 — current version Jun 17, 2026 · View on Municode
High-Velocity Hurricane Zone
Construction in Miami-Dade and Broward counties must meet these HVHZ-specific requirements in addition to the standard Florida Building Code. These provisions apply to all new construction, additions, and substantial improvements.
Miami-Dade County is designed for 175–185 mph ultimate design wind speeds (ASCE 7-22). All structures must be engineered for these extreme wind loads — significantly higher than the 130 mph minimum for most of Florida.
ASCE 7-22 §26 / FBC §1609All exterior building products — windows, doors, roofing, cladding, skylights — must carry a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval. No substitutions permitted without re-testing.
FBC §1609.1.2 / MDC §8-5All exterior glazing in HVHZ must be impact-resistant (ASTM E1886/E1996 Large Missile Level D) or protected by approved impact-resistant shutters. Standard tempered glass is not sufficient.
FBC §1609.1.2 / MDC §8-5Continuous load path from roof to foundation required. Roof-to-wall, wall-to-floor, and floor-to-foundation connections must be engineered and verified by special inspection. Uplift straps at every rafter/truss.
FBC §1604.8.2 / ASCE 7-22Products must be tested per Miami-Dade test protocols (TAS 100–203) or equivalent ASTM standards. The Miami-Dade Building Code Compliance Office (BCCO) maintains the approved product database.
MDC Chapter 8 Art. IV / FBC §1609Buildings >3 stories or >50 ft require threshold inspections by a licensed structural engineer or architect throughout construction. Threshold inspector must be on-site during critical structural work.
Fla. Stat. §553.79 / FBC §110.3Product Testing Standards
