What defines a manufactured home according to federal regulations?

A manufactured home is defined by federal regulations as a transportable structure built on a permanent chassis. This definition emphasizes two key characteristics: the ability to be transported and the presence of a permanent chassis, which provides the necessary support for the structure during transport and placement.

The notion of being "transportable" indicates that manufactured homes can be moved from one location to another, a crucial aspect that distinguishes them from traditional site-built homes. The permanent chassis serves as a foundation that allows the home to be transported safely, ensuring it remains structurally sound during movement.

In contrast, the other options do not align with the regulatory definition. A structure that cannot be transported contradicts the very nature of manufactured homes, which are designed for mobility. A home requiring no utility connections is inaccurate, as manufactured homes typically do need utility connections for functioning like electricity, water, and sewage. Lastly, a home built only for temporary use does not fit the definition of manufactured homes, which are generally intended for long-term residency.

Thus, option B accurately encapsulates the core elements defining a manufactured home according to federal regulations.
