Yes, a modular home is not a mobile home; it is simply a home that is built off-site, as opposed to on-site. These homes are often called factory-built, system-built or prefab (short for prefabricated) homes. Modular and manufactured homes are not the same. Manufactured homes are not placed on permanent foundations. Modular homes are also very customizable, are much higher quality, and most important, recognized as single family homes by Housing and Urban Development and The Federal Housing Administration.
