Edited by John Voll. Last verified .
In Louisiana, the state keeps license or registration records for general contractors, electrical contractors, plumbing contractors, HVAC contractors and roofing contractors, and each has an official lookup or board listed below. Check the record before you sign a contract or pay a deposit, and treat the board's own record as final.
Which board covers which trade
| Trade | Who keeps the record | Official lookup |
|---|---|---|
| General contractor | Louisiana State Licensing Board for Contractors | Search general contractor licenses |

| Plumbing | State Plumbing Board of Louisiana (individual plumbers); Louisiana State Licensing Board for Contractors (Plumbing classification for jobs over $10,000) | Search plumbing licenses |
