Yes and this influences even the places at higher latitudes. I live in WA state and it's very clear that during the 50s-90s a lot of the residential construction here was influenced by what was going on in California. I know a lot of trades people that moves up from CA in that time.

So the houses are not built to adequately handle rain and are drafty due to colder temps here. WA state finally started instituting more specific build codes that match the region in the late 90s and 2000s

Climate in much of the US is far from being mild. Winters are pretty cold at lower latitudes, and summers can be very hot.
