Fort Lauderdale is in Broward County’s High-Velocity Hurricane Zone, so the enforceable design speed is 170 mph and the code is ASCE 7-22 under the Florida Building Code 8th Edition. Enter an address and get C&C, MWFRS, and roof design pressures in psf, matched to product approvals, with a permit-ready Engineering Report.
Fort Lauderdale is in Broward County, one of Florida’s two HVHZ counties. That single fact drives the whole calculation: the design wind speed, the products you can install, and what the plans examiner will and won’t accept.
Across Fort Lauderdale and the rest of Broward, the enforceable Risk II design wind speed is 170 mph. It is set by the county’s HVHZ status, so the value that clears review is fixed — get it wrong and the submittal bounces.
The Florida Building Code 8th Edition governs Fort Lauderdale permits, and it references ASCE 7-22 for wind. Our engines are 7-22 throughout, with the HVHZ pressures layered on where the county requires them.
In HVHZ, windows, doors, and shutters carry a rated design pressure through a Notice of Acceptance or Florida Product Approval. Your calculated pressure has to sit within that rating for the zone the opening is in.
The HVHZ math is handled; you supply the building.
Type a Fort Lauderdale address or ZIP. The 170 mph Broward HVHZ design speed and the site exposure load automatically.
Set the dimensions, height, roof shape, and enclosure, and choose the surface — wall, roof, or whole structure.
Design pressures come out in psf by zone, ready to compare against product approvals and to carry into the structural design.
Export the Engineering Report with each factor pinned to its ASCE 7-22 clause for the Broward submittal.
Whatever the plan review asks for, the pressure comes out in psf at the 170 mph HVHZ speed.
Component & cladding pressures to match against a Notice of Acceptance for each opening, corner zones included.
Uplift for flat, gable, hip, and monoslope roofs — the corner and edge suction that governs membranes, tiles, and fasteners in HVHZ.
Directional pressures on every wall and the roof for the structural frame, additions, and new construction.
Freestanding walls, signs, rooftop equipment, and specialty structures under ASCE 7-22 Chapter 29.
Rooftop and ground-mount PV, parapets, and attached canopies at the Broward HVHZ speed.

The Risk II design wind speed for Fort Lauderdale is 170 mph, set by Broward County’s High-Velocity Hurricane Zone status. Higher risk categories step up from there. The calculator applies the enforceable value the moment it detects a Fort Lauderdale address.
Yes. Fort Lauderdale is in Broward County, one of the two HVHZ counties in Florida along with Miami-Dade. That is why the design speed and the product-approval requirements are stricter than most of the state.
The Florida Building Code 8th Edition, which references ASCE 7-22 for wind loads. Our calculators are ASCE 7-22 throughout, with the Broward HVHZ pressures applied where the county requires them.
It depends on the scope and the reviewer. The software output is an Engineering Report, not a sealed document. A PE sign-and-seal is a separate service — available through our in-house Florida P.E. for residential up to three stories and our PE network beyond that.
Yes. The calculator returns design pressures by zone and effective wind area, so you can compare each opening’s value to the rated design pressure on its NOA or Florida Product Approval before installation.
Yes — uplift for flat, gable, hip, and monoslope roofs with corner and edge zones, at the Broward HVHZ speed, for both new construction and re-roofing submittals.
