New Building Code for Modular Homes

A new building code is in effect for modular homes in South Carolina.  

Modular homes are built to the same construction code as site-built houses, known as the International Residential Code.

The code is updated every three years; it covers all aspects of construction from foundation and wiring to plumbing and the roofing.

South Carolina adopts its own version of the International Residential Code, adapting it to local construction needs.  The provision of the SC version of the Code are reviewed and issued by a state agency, the SC Building Code Council. Then it goes to the SC legislature for final approval.

The Manufactured Housing Institute of SC holds a seat on the Building Code Council, representing the modular industry. Over 80% of modular homes sold in South Carolina are built by MHISC member manufacturers.
