Which document certifies that a manufactured home meets federal safety standards?

The HUD label is the correct answer because it serves as the certification that a manufactured home complies with the federal safety standards established by the U.S. Department of Housing and Urban Development (HUD). This label is typically a metal tag affixed to the home, indicating that it has been inspected and meets specific construction and safety requirements. The presence of the HUD label assures buyers and regulators that the manufactured home adheres to the federal standards intended to protect the health and safety of its occupants.

The other options do not specifically serve this certification purpose. A building permit is generally issued by a local authority to ensure proposed construction meets local codes, but it does not guarantee adherence to federal standards specific to manufactured homes. Construction approval may denote that plans and specifications have been reviewed, but it lacks the certification aspect specific to federal safety compliance. A safety inspection report can denote that a home has been checked for safety features, but it does not necessarily indicate compliance with the specific federal standards that the HUD label guarantees.
