Basic Facts About Contracting in California

  • Anyone performing construction work in California that totals $500 dollars or more in labor and materials must be licensed by CSLB.
  • The construction industry is one the largest industries in California. www.labormarketinfo.edd.ca.gov
  • Licensed contractors must demonstrate at least four years of experience/education in the trade for which they are licensed, be fingerprinted, have an FBI background check, and be bonded.
  • CSLB's Statewide Investigative Fraud Team (SWIFT) conducts stings and sweeps somewhere in California each week.
  • Unlicensed contractors are part of the $60-140 billion underground economy that does not pay taxes, insurance, or follow safety laws. www.dir.ca.gov/LETF/LETF.html
