When Are Impact Windows
Required vs. Optional?
Not every Florida address mandates impact glass. Here’s how to know if you’re required — and when it’s still the smartest choice.
Legally Required
When They’re Required
Code Requirement
Impact windows are legally required when:
Your home is in a High Velocity Hurricane Zone (HVHZ) — all of Miami-Dade and Broward.
You’re within 1 mile of the coast in a wind-borne debris region.
Your county wind speed zone exceeds 120 mph.
You’re doing a full window replacement requiring permits.

The Verdict
The Bottom Line
“For most Florida homeowners, it’s not a question of if — but when.”
Even if your county doesn’t require it, the insurance savings, security benefits, and energy efficiency of impact windows typically pay for themselves within 5–7 years. The math is straightforward: lower premiums, lower energy bills, and a home that’s genuinely safer during storm season.
