Steel & concrete modular homes in South Dakota
Modular homes are built to state and local building codes and set on a permanent foundation. Here is what applies in South Dakota.
South Dakota program
- Administering agency
- SD Electrical Commission (Dept. of Labor and Regulation) - electrical inspection of modulars only
- Program / authority
- ARSD 20:44:23 (modular homes and structures electrical inspection)
- Code basis
- National Electrical Code for modular wiring; no statewide structural code for residential found (SDCL 11-10 excludes residential)
- Inspection & seal
- Wiring permit required for each modular unit made in or moved into SD; inspection via NRTL label, state in-factory inspection, licensed wiring, or approved third party.
- Good to know
- Structural building code enforcement is local; SDCL 11-10 default IBC provisions exclude residential structures, so check the city/county.
