Who must be licensed in Louisiana

Louisiana requires a state contractor licence from the Louisiana State Licensing Board for Contractors for commercial and residential projects above statutory dollar thresholds, with licence classifications that must match the work performed. Electrical, plumbing, and mechanical trades are also regulated through state boards and mechanical licensing. Parishes and cities issue building permits under the Louisiana State Uniform Construction Code, with hurricane and flood provisions especially important south of I-10. Verify licence numbers on the LSLBC contractor search and trade board lookups before paying deposits on storm-hardening or elevation projects.

Contractor hiring checklist

Insurance and bond minimums

LSLBC licensees must maintain general liability insurance and workers’ compensation as required by board rules. Coastal parishes may require additional documentation for wind and flood compliance.

Who issues permits

Louisiana enforces the Uniform Construction Code through local inspectors. LSLBC licences who may contract above thresholds; parishes issue permits.

Homeowner permits — can you pull one, and should you

Owner-occupiers may obtain permits in many parishes with owner-builder affidavits. Licensed contractors must perform regulated trade work. Flood zones require elevation certificates for substantial improvement.

Deposits, cancellation rights, and liens

Deposit rules: Louisiana does not use California’s deposit cap. The Unfair Trade Practices Act still prohibits deception — document progress payments.
Rescission / cooling-off: Door-to-door home repair contracts may include cancellation rights under federal and state solicitation laws when notices are delivered.
Mechanic's lien timeline: Louisiana Private Works Act (La. R.S. 9:4801 et seq.) sets notice and filing rules that differ from many other states — owners should consult counsel on large projects.

Where to file a complaint

File LSLBC complaints for unlicensed contracting or classification mismatches. Trade board complaints go to electrical and plumbing boards. Consumer fraud may be reported to the Attorney General.

If you hire someone unlicensed

Unlicensed contracting above thresholds is unlawful and can void insurance coverage after hurricane losses when work was not permitted or inspected.
