Manufactured homes are typically habitable for around 55 years. Manufactured, or mobile homes, are homes that are made in a factory as opposed to being built on site. Prior to 1964, manufactured homes only tended to last for around 10 years.
The U.S. Department of Housing and Urban Development (HUD) issues federal safety standards for factories that produce manufactured housing. Performance requirements are set for structure, plumbing, fire safety, energy efficiency and transportation from the factory to the lot. The National Conference of States on Building Codes and Standards (NCS/BCS) works with the U.S. Department of Housing and Urban Development to monitor factories for quality and safety of manufactured housing.
