The Mobile Home Construction and Safety Standards Act of 1974 or National Mobile Home Construction and Safety Standards Act is a United States federal law establishing design, construction, installation and development safety standards for manufactured housing. It ensures prefabricated homes' quality, durability, safety and affordability. The program also includes a dispute resolution component, and the buyer can file civil and criminal penalties for violations of the statute. The Department of Housing and Urban Development (HUD) issues and enforces these standards and applies to all manufactured homes produced after June 15, 1976. They inspect factories and retailer lots and review records to implement the standards. The imposed guidelines prohibit selling and leasing manufactured homes that do not meet their standards.
