Typically, no. Due to our high water table, most homes are built on a concrete block foundation. Double-wide mobile homes are usually on a concrete block foundation, although some can be found on concrete block piers. Most interestingly, homes near tidal waters can often be found perched high on top of huge wood pilings, including stick-built, double-wides and single-wides.
