When were the first standards for plumbing, heating, and electrical systems established?

The first standards for plumbing, heating, and electrical systems in manufactured homes were established during the federal government's implementation of regulations on January 1, 1977. This was a significant moment in the manufactured housing industry as it laid the groundwork for improving safety and quality in these essential systems. Prior to this, there were no standardized guidelines, which often resulted in inconsistencies and safety concerns. By establishing these standards, the government aimed to protect consumers and ensure that manufactured homes provided satisfactory living conditions. The date is crucial in understanding the evolution of manufactured home construction and safety protocols.
