Florida's Strictest Zone

What Is an HVHZ — and Does Your County Qualify?

Florida's High-Velocity Hurricane Zone (HVHZ) designation applies to Miami-Dade, Broward, and Monroe (Florida Keys) counties. These areas are subject to the Miami-Dade Building Code — one of the most rigorous wind codes in the world.

In HVHZ counties, it is illegal to install a garage door that doesn't have a valid Notice of Acceptance (NOA) from Miami-Dade County Product Control. A standard wind-rated door — even one that meets the rest of Florida's code — is non-compliant in these zones.

Even outside HVHZ, Palm Beach, Collier, Sarasota, and Pinellas counties face elevated coastal wind loads that should factor into your door selection.

If you're in Miami-Dade or Broward

Your contractor must pull a permit, and the door must carry a valid NOA. Unpermitted replacements in HVHZ can result in fines, forced removal, and insurance claim denials after a storm.

months of hurricane season

June 1 through November 30 — every year

Florida's Window to Prepare Is Narrow

Florida's Atlantic hurricane season officially runs June 1 – November 30. But subtropical storms can form outside that window, and the busiest period — late August through October — often gives homeowners only days of warning before a storm arrives.

Garage doors are statistically the most vulnerable large opening on a home. A compromised door can fail under wind pressure, depressurizing the structure and dramatically increasing the risk of roof loss. Inspecting and upgrading before June 1 is the safest window.

Annual Prep Calendar

When to Do What — Every Year

A simple timeline for Florida garage door maintenance aligned to hurricane season.

Jan – Mar

Post-season check

Inspect for storm damage, rust, gaps. Service springs and cables.

Apr – May

Pre-season upgrade window

Best time to replace or upgrade — contractors less backlogged.

Jun – Aug

Active season — monitor

Watch forecasts. Keep door maintained. Don't do major work.

Sep – Oct

Peak storm risk

Storm prep only. Check hardware, test manual release.

Nov – Dec

Schedule next year's work

Book a wind mitigation inspection. Plan upgrades for off-season.

Warning Signs

4 Signs Your Door Won't Survive a Storm

These don't always mean immediate danger — but they mean your door needs evaluation before hurricane season.

Visible daylight around the edges

Gaps between the door and frame create pressure points. In a storm, this allows wind-driven rain inside and structural pressure to build.

Spring or cable wear (slow movement, squealing)

Fatigued springs can snap under the extra wind load of a storm — leaving the door unable to close or lock securely.

Rust on hinges, rollers, or panels

Florida's salt air accelerates corrosion. Rusted components lose strength and can fail under impact or sustained wind pressure.

No wind rating sticker on the door

If there's no sticker, assume no wind rating. An unrated door installed before 2001 likely doesn't meet any current FL code.

Insurance Impact

How Your Garage Door Affects Your Homeowner's Insurance

Florida's Office of Insurance Regulation (OIR) mandates that insurers offer wind mitigation discounts for homes with qualifying hurricane-resistant features. Garage doors are explicitly included — impact-rated doors with an NOA can earn significant credits.

To claim the credit, you need a certified wind mitigation inspection (Form OIR-B1-1802). The inspection report is submitted to your insurer, who then re-rates your premium. Coastal homeowners typically see the largest discounts.

HVHZ

$300–$800/yr

Coastal

$150–$500/yr

Inland

$100–$300/yr

Estimated annual savings from switching to impact-rated garage door. Actual savings vary by insurer and policy.

Emergency Checklist

When a Storm Is Coming: Garage Door Prep

01

Do NOT use horizontal bracing bars alone

Bracing kits reduce deflection but don't make a standard door impact-rated. In a major storm, the door can still fail.

02

Disconnect the automatic opener

If the door is blown off track, an opener can burn out or create a dangerous situation. Disconnect and lock manually.

03

Don't open the garage door during a storm

This is the single biggest risk factor. Keep it closed and locked — wind uplift on an open door is catastrophic.

04

Check the manual lock is engaged

Most doors have a manual slide bolt. Confirm it's locked before leaving or sheltering.

05

After the storm: check alignment before using

Wind pressure can shift tracks and warp panels. Operate manually first to check for binding or damage.
