Steel & concrete modular homes in South Carolina
Modular homes are built to state and local building codes and set on a permanent foundation. Here is what applies in South Carolina.
South Carolina program
- Administering agency
- SC Dept. of Labor, Licensing and Regulation (LLR), Building Codes Council
- Program / authority
- Modular Building Program; S.C. Code Title 23, Chapter 43; Regulations Art. 6 (8-600 et seq.)
- Code basis
- Same construction codes as site-built buildings (edition not stated); additions must follow current IBC series and NEC
- Inspection & seal
- Licensed manufacturers use licensed third-party inspection agencies; each building gets a Council-issued label on the electrical panel door.
- Good to know
- Label is valid only for first placement; out-of-state dealers are not licensed to sell modular buildings for SC, though consumers may buy direct from manufacturers.
