Contractor Licensing Requirements in Louisiana

Louisiana requires contractors to be licensed through a single statewide agency once project values cross set dollar thresholds. Whether you’re bidding a commercial build or a residential remodel, understanding which license class applies — and what the state requires to issue it — is the first step to legally taking on work.

Louisiana’s Contractor Licensing System

The Louisiana State Licensing Board for Contractors (LSLBC) is the single statewide authority overseeing contractor licensing. Louisiana sets separate monetary thresholds by project type: commercial projects worth $50,000 or more require a Commercial license, while residential projects require a license once the contract value exceeds $75,000. Home improvement work between $7,500 and the residential threshold generally falls under a Home Improvement Registration instead.

License Classes in Louisiana

• Commercial License — required for commercial or industrial construction projects valued at $50,000 or more
• Residential License — required for new residential construction valued at $50,000 or more
• Home Improvement Registration — required for repairs or improvements to existing residential structures valued between $7,500 and $50,000
• Mold Remediation License — required for mold remediation work valued at $7,500 or more, plus various specialty/trade classifications (electrical, mechanical, plumbing) under the Commercial license umbrella

Exam & Experience Requirements

Applicants must pass a Business & Law exam plus a trade-specific exam for their chosen classification, both administered through PSI on behalf of the LSLBC. The board also reviews financial qualifications, requiring a minimum net worth, a bank line of credit, or a surety bond depending on the license type and project size.

NASCLA Reciprocity

Louisiana participates in the NASCLA reciprocity program and accepts the NASCLA Accredited Examination for Commercial General Building Contractor in place of its own commercial trade exam. Applicants using the NASCLA exam still must pass Louisiana’s separate Business & Law exam and meet all financial requirements.

Bonding & Insurance to Get Licensed

The LSLBC requires applicants to demonstrate financial responsibility through a minimum net worth, a bank line of credit, or a surety bond, and general liability insurance is generally required to hold an active license. Trade Safe can help contractors get the right coverage in place quickly so it’s not a bottleneck in the application process.

Reciprocity with Other States

Beyond the NASCLA exam substitution for commercial licensure, Louisiana does not maintain broad direct license-for-license reciprocity agreements with other states — out-of-state contractors generally still need to meet Louisiana’s own application, exam, and financial requirements.
