I found this information to be important. EF2 tops out at 135mph. Just how much resistance would there be to code changes for minimums in all areas?

In some jurisdictions, it would be all but impossible to require minimums...….As an example, just look at the
"minimums" for Accessibility........20+ years in and there is still "push back"......Also, look at the thousands
of postings by the ICE Man...…...They can't \ won't perform the minimums on basic construction.

Wind loads increase with the square of the wind speed, so designing for 135 MPH instead of 90 MPH (working stress design) would slightly more than double the wind loads. The entire country would have to meet the same wind standards as the Gulf coast and South Florida. The wind loads in the 2012 and later IBC are for ultimate stress design, which is on the verge of structural failure.

My area is 170mph. The panhandle is less and it decreases as you go north

I'd rather build a house that meets the demands of a changing climate and more volatile weather than build something cheaper. Things are what they are. Eventually the insurance industry will force change like they did in Florida.

Rembo, respectfully sir, ...while your desire to build to a changing climate is admirable, IMO you would not be
to be in the Residential new homes business for very long...…..Along with the actual evidence, even the
fearmongering weather voices are stating that climate change is causing the weather patterns to cause
increasingly stronger & more catastrophic events...…...How much can the insurance industry do to require
Res. constructors to build "above ground, hardened bunkers" ?...……..And the stronger weather events
are not just along the coastlines either !...….Fires in the West, ...wind events everywhere, ...snows,
...tornadoes that are commonly EF-4 and above, ...droughts, ...flooding, and on and on and on......Even

lightning damaging events are becoming more common and more costly.
