Louisiana licenses contractors through the Louisiana State Licensing Board for Contractors, and the thresholds are low enough to catch most real work. A commercial license is required for projects of $50,000 or more, and commercial electrical, mechanical, and plumbing work needs a license at just $10,000.

Facts checked on September 1, 2026.
Each line was checked against the state board’s published requirements on the date shown. Not stated means the board material we reviewed did not state it, so we do not guess. Boards change rules; confirm the current figure with the board before you file.
Residential construction requires a license above $75,000, home improvement work requires registration at $7,500 and up, and mold remediation is licensed at $7,500 and up. Every commercial, residential, and mold license rides on a qualifying party, the person who passes the exams for the classification, so the qualifying party rule is the center of Louisiana licensing.
