Manufactured home communities seem to attract tornados. There is no meterological or scientific basis to thinking that manufactured home communities attract tornados. Above this range, a manufactured home will experience some form of damage. A direct hit from a tornado will bring about severe damage or destruction of any home in its path. If a manufactured home has a below-ground basement, the home's residents should seek shelter there.
Manufactured homes are less safe in hurricane winds than other forms of housing.
In both of these zones, the standard for manufactured homes is now more stringent than the current regional and national building codes for site-built homes located in these wind zones. An important element in the adequate wind safety of a manufactured home is the proper installation and anchoring of the home according to the manufacturer's instructions. When properly installed and anchored, the manufactured home's wind resistance is significantly improved. Manufactured homes are less energy efficient than site-built homes and suffer moisture damage from inadequate ventilation. Prior to this new energy rule, the thermal zone map for the United States, minus the states of Alaska and Hawaii, was comprised of two zones.
