Common pitfalls

Mistakes we see installers make when navigating South Carolina licensing.

  • South Carolina splits residential and commercial onto two different boards. Doing both = holding licenses from both Contractor's Licensing Board AND Residential Builders Commission.
  • Alarm work (BAS / FAS) is on a third board. A common mistake is assuming the ELE Electrical license includes alarm scope - it does not.
  • Bid limits are tied to financial statements. Going over your stated bid limit on a single project invalidates the license for that job.
