Maybe. But in an area that is ravaged by hurricanes more than my area is by earthquakes then one has to wonder why the local government is not looking at strengthening the codes.
OK - one more.
Building codes for new construction are steeper than when older mobiles and homes were made. But you aren't required to bring your house up to every new code that is passed, and thank goodness for that. They'd keep us all broke. Code improvements come up and are required when you do a major remodel or addition. Some apply when you try to sell or finance it. Short of that, new code doesn't apply to old homes.
