What Each Item Means

1

Wind Load Calculations

Think of wind load as how hard the wind pushes on a building. In Miami-Dade, buildings must handle 180 mph winds. That is like a Category 5 hurricane pushing on every window and door. Your calculations show exactly how much push each part of the building will feel.

WindLoad.co generates ASCE 7-22 compliant calculations in 3 minutes
2

Product NOA Numbers

NOA stands for Notice of Acceptance. It is like a permission slip that says a product has been tested and approved for Miami-Dade. Every window, door, and shutter needs one. Without it, your permit will be rejected.

Look up NOA numbers on the Miami-Dade Product Approval website
3

PE Sealed Documents

A Professional Engineer (PE) stamp means a licensed engineer reviewed and approved your calculations. It is like getting a doctor to sign off on a prescription. Most commercial projects need this stamp for permit approval.

We offer 24-hour PE seal turnaround for Miami-Dade projects
4

HVHZ Product Approval

HVHZ means High Velocity Hurricane Zone. Miami-Dade and Broward are the only counties with this special designation. Products sold here must pass extra tests that simulate flying debris and extreme pressure. Regular Florida-approved products are not enough.

Always verify HVHZ approval before ordering products
5

Installation Details

Even the strongest window fails if installed wrong. Your permit package must include how products will be attached. This means screw spacing, anchor types, and sealant specifications. Think of it as the instruction manual the inspector wants to see.

Manufacturer installation instructions are part of the NOA

Common Questions

What wind load documents do I need for a Miami-Dade permit? +
For Miami-Dade permits, contractors need: wind load calculations per ASCE 7-22, product approval numbers (NOAs) for all exterior products, signed and sealed drawings if required, and proof that products meet the 180 mph wind speed requirement for HVHZ areas.
Do contractors need a PE seal for wind load calculations? +
Yes, most Miami-Dade commercial projects require a Professional Engineer seal on wind load calculations. Residential projects may use prescriptive tables, but custom calculations typically need PE certification for permit approval.
