Licensing
Do you need a license in South Carolina?
Garage door repair is often handled as a service trade, but installation work in South Carolina can fall under residential or general contractor licensing depending on scope, and electrical opener wiring may involve other trade rules. A local business license generally applies. A NISCR certificate is a professional credential, not a government license, so verify current South Carolina contractor and municipal requirements before performing installations.

|---|---|---|
| What it is | Legal permission from a state agency to perform regulated work. | Proof you completed training and passed an exam, issued by an industry body. |

A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it. Licensing rules change and vary by city and county. Always confirm current requirements with your state licensing board before performing work.
