What is a Wind-Borne Debris Region?
Understanding Florida's wind-borne debris regions and building code requirements
Official Definition
Florida wind-borne debris requirements depend on the currently adopted code, risk category, site wind-speed map, coastal criteria, and jurisdiction. Confirm the property-specific criteria with the building official and responsible design professional.
Geographic Coverage
The applicable wind-borne debris criteria can include:
- Coastal locations identified by the currently adopted code and wind-speed maps
- Locations that meet the applicable risk-category and site wind-speed criteria
- Some inland properties, depending on the current map, code edition, and jurisdiction
High-Velocity Hurricane Zone (HVHZ)
Florida Building Code HVHZ provisions apply in Miami-Dade and Broward counties. Projects elsewhere must follow the code, product-approval, design, permit, and installation requirements applicable to that property.
HVHZ Counties Include:
- Miami-Dade County
- Broward County
Protection Requirements by County

Impact-Resistant Windows
Opening protection must follow the code, permit, product approval, and installation requirements applicable to the property
Building Code Compliance
Must meet or exceed Florida Building Code requirements for wind-borne debris regions
Miami-Dade NOA
Confirm the exact product approval accepted for each opening and jurisdiction before ordering
Professional Installation
Installation must be performed by licensed contractors with proper permits
Miami-Dade Notice of Acceptance (NOA)
Product approvals and requirements must be verified for the exact opening and jurisdiction
What is Miami-Dade NOA?
Miami-Dade and Broward projects are subject to HVHZ provisions and local permitting review. Confirm the product approval, design pressure, opening, exposure, and installation details accepted by the authority having jurisdiction.
NOA Requirements Include:
- Large and small missile impact testing
- Cyclic pressure testing
- Water infiltration resistance
- Forced entry resistance testing
For each quoted assembly, request the current approval and test documentation and verify that its dimensions, design pressure, configuration, and installation match the opening. No product eliminates all storm risk.
Why Review Product-Approval Documentation?
- Confirm impact and cyclic-pressure testing for the exact assembly
- Provide exact documentation for insurer-specific review
- Verify any forced-entry resistance in the exact product test data
- Product-specific tested performance documented for the quoted assembly
Benefits of Compliance
Beyond meeting building code requirements, impact windows and doors provide numerous advantages

Frequently Asked Questions
What happens if I don't comply with wind-borne debris region requirements?
A noncompliant scope may create code, permit, inspection, safety, insurance, or property-disclosure issues. Outcomes depend on the jurisdiction, project, policy, carrier, and transaction, so consult the relevant authority and professionals.
Can impact windows affect my insurance premium?
Insurance eligibility and premium changes vary by carrier, policy, property, inspection findings, documentation, and opening protection. Ask the insurer to evaluate the specific home before estimating any credit.
Do I need permits for impact window installation?
Permit and inspection requirements vary by jurisdiction, property, opening, and scope. Confirm them with the building department, and require the written proposal to identify who prepares, submits, pays for, schedules, and closes each item.
How long does the installation process take?
Installation schedules depend on product scope, permitting, inspections, access, and site conditions. We provide a detailed project-specific schedule during the consultation.
