Prior to the start of the Modular Buildings Program, modular buildings, which are factory fabricated in whole or in part, were not required to be constructed to any recognized building code. To provide a safe and healthy indoor environment, therefore, the Modular Buildings Program was created to establish a process that would assure a minimum level of safe construction for all modular buildings destined for use in South Carolina. To serve that purpose, the legislature determined that modular buildings should provide the same degree of safety to their occupants as buildings constructed on site. The program thus incorporates all construction codes that are authorized and adopted for use for site built structures. The program requires all modular building manufacturers to be licensed and to employ independent (third party) inspection agencies to inspect and certify that their buildings meet or exceed the required building codes. The program has been in effect since 1984 and presently has more than 100 manufacturers throughout the country that are licensed to do business in the state.
