Building or buying a home in South Florida means building or buying a home in one of the most hurricane-active regions in the United States. Miami-Dade County enforces some of the strictest building codes in the country — for good reason. But not all builders interpret those codes the same way, and not all homes are created equal when the wind starts to blow.
Here’s what you need to know before you sign any contract with a builder in South Florida.
Impact Windows and Doors: Non-Negotiable
Since Hurricane Andrew in 1992, Miami-Dade County has required impact-resistant windows and doors on all new residential construction. These are not storm shutters — they are permanently installed laminated glass units that meet Miami-Dade’s High-Velocity Hurricane Zone (HVHZ) standards, the toughest in the nation.
What to ask your builder: Are the impact windows Miami-Dade approved? Ask for the Notice of Acceptance (NOA) number. All Presto Construct homes use Miami-Dade approved impact products as standard.
Roof Systems: Where Homes Win or Lose
The roof is the most critical component of hurricane resistance. Key elements include:
- Secondary water barrier (SWB): Required in Miami-Dade — a self-adhering underlayment that protects your home even if the roof covering is damaged.
- Roof-to-wall connectors: Hurricane straps or clips that attach roof trusses to the wall framing. In high-wind zones, these must meet specific uplift ratings.
- Tile weight and attachment: Concrete tile is common in South Florida. Proper mortar-set or mechanical attachment is critical for wind resistance.
Concrete Block vs. Frame Construction
Most South Florida homes are built with concrete masonry units (CMU) — concrete block walls reinforced with rebar and filled with grout. This construction method provides excellent wind and impact resistance and is the standard for residential construction in Miami-Dade. All Presto Construct homes are CBS (Concrete Block and Stucco) construction.
Garage Doors: The Weak Link
Garage doors are one of the most vulnerable openings in a home during a hurricane. Miami-Dade requires garage doors to meet wind load ratings. Look for the Miami-Dade NOA and make sure your builder installs compliant doors — not the bare minimum.
Questions to Ask Every Builder
Before you sign with any builder in South Florida, ask these questions:
- Are all windows and doors Miami-Dade HVHZ approved?
- What hurricane strapping system do you use on roof trusses?
- Is the garage door Miami-Dade wind-rated?
- Will the home have a secondary water barrier on the roof?
- What is the concrete block fill schedule?
