Wind mitigation is not limited to Florida, Florida was the first for obvious reasons. I heard that NJ was looking at also. I personally like to see other points of views. Other areas of the world have different construction issues they have to deal with, many of, I am glad I do not need to be concerned with.
After living in the North East for many years I am glad I do not have to inspect those home. I have nothing but respect for those that inspect those older homes. I assure you it is much easier to inspect a newer slab on grade home here in Florida, no basement, no, crawl, and next to no attic. All that being said there are several unique items we pay attention to and may seem to do some items backwards. When you build in a hot and humid environment some things have to change.
Wind Mitigation reports are unique to the fact that they are not about building codes, but statistics. These are the items that insurance companies track. It is about loss prevention and not if the proper code or better than code being followed. Anyone doing insurance inspections must just accept it.
