Wind load is the same physics everywhere, but the number that passes plan review isn't. These state and county pages start from ASCE 7-22 and apply the local code overrides that govern your permit — Florida HVHZ, Texas TWIA, California Title 24, and the rest. Every ZIP in all 50 states is covered.
Each state page applies that state's adopted edition of the building code on top of ASCE 7-22, so the design wind speed you get is the one your reviewer expects.
Three South Florida counties carry Florida Building Code R301.2(7) wind speed overrides above the raw ASCE map, and two of them sit in the High-Velocity Hurricane Zone. Each gets its own calculator and wind-speed reference.
The dedicated pages above are the jurisdictions we're asked about most. The engine itself isn't limited to them — it carries a pre-verified ASCE 7-22 design wind speed for every ZIP code in all 50 states, for all four Risk Categories.
Drop any ZIP into the free tool and you'll get the design wind speed back immediately, no signup.
Because the building code, not just ASCE 7-22, decides what passes review:
The jurisdiction is just the wind speed. Run any U.S. ZIP through the calculator for zone-by-zone components & cladding and MWFRS pressures, every coefficient cited to its ASCE 7-22 section, and a permit-ready Engineering Report.
Every ZIP code in all 50 states is covered. The state and county pages in this directory are dedicated landing pages for the jurisdictions we get asked about most — Florida, California, Texas, the Carolinas, Virginia, Louisiana, and Hawaii.
If your state isn't listed yet, the free tool still returns the ASCE 7-22 design wind speed for any U.S. ZIP.
Three Florida counties — Miami-Dade, Broward, and Collier — carry Florida Building Code R301.2(7) wind speed overrides that exceed the raw ASCE 7-22 map value, and Miami-Dade and Broward are in the High-Velocity Hurricane Zone (HVHZ).
Those rules change what passes plan review, so each county gets its own page.
All of them use ASCE 7-22, the latest edition of the standard, layered with each jurisdiction's adopted building-code amendments — for example the Florida Building Code 8th Edition and California's 2025 Title 24.
