The location and spacing of the piers, and therefore the footers, depends on the dimensions and weight of the home, the roof load zone and the type of construction. Other factors such as the locations of doors or other openings and heavy pieces of furniture also need to be considered.

Pier blocks, (shown at right), on footers.
All foundations must meet your local building codes.
Since modular homes do not use pier blocks, this type of foundation isn't usually used for them.
There is another type of foundation called "Sure SafeŽ" that you might want to ask your dealer about. It is available in all states except Florida, (who is still testing it as of 2006), and is one that some people will be interested in. It works by suspending a steel support from a steel beam under a structure. The base of the support that is hanging about 3'' above the ground is placed inside a specially designed bag that is then filled with about three cubic feet of concrete. The factory-engineered foundation system is said to be cost-effective and provides plenty of lateral and load support for buildings, according to the manufacturer.
