Trade business resources for Louisiana.

In Louisiana, contractors who perform work exceeding $50,000 (including materials and labor) on commercial or residential projects must be licensed by the Louisiana State Licensing Board for Contractors (LSLBC). Specialty trade contractors such as electricians, plumbers, and HVAC technicians have separate licensing requirements administered by their respective state boards, regardless of project dollar amount.

State licensing board

Louisiana uses a tiered licensing structure based on project value and trade type. General contractors performing commercial work over $50,000 must hold a commercial license from the LSLBC, while residential contractors performing work over $75,000 must hold a residential license (or home improvement registration for projects between $7,500 and $75,000). Electrical contractors are licensed by the Louisiana State Uniform Construction Code Council and must employ a licensed master electrician. Plumbers are regulated by the State Plumbing Board of Louisiana, requiring journeyman and master plumber licenses for most plumbing work regardless of dollar threshold. HVAC contractors must be licensed by the Louisiana State Licensing Board for Contractors under the mechanical specialty classification for commercial work over $50,000, while residential HVAC work has its own classification. Roofing contractors performing work over $75,000 residentially or $50,000 commercially must also hold an LSLBC license, and a separate roofing subclassification exists within the board's specialty contractor categories.
