Louisiana Mold Contractor Licensing Rules

Louisiana's Single License Type

Louisiana's approach differs from other states in that it doesn't require homeowners to hire two separate companies by default. A Louisiana-licensed contractor has the legal authority to perform both assessment and remediation — the restriction is that they cannot perform both roles on the same property.

The Conflict-of-Interest Rule

La. R.S. §37:23 establishes Louisiana's mold contractor COI rules:

• §37:23(c): A licensed mold remediation contractor who performs mold assessment on a property shall not perform mold remediation on the same property.
• §37:23(d): No person shall own an interest in an entity performing mold assessment and an entity performing mold remediation on the same property.

Why Louisiana Uses a Single License

Louisiana's single-license approach reflects a regulatory philosophy that focuses on contractor competency rather than role separation at the licensing level. The theory is that a mold contractor should understand the full spectrum of mold work — assessment, protocol development, remediation technique, and clearance testing — and the COI rule then enforces independence on any given job.

This means Louisiana homeowners may have more flexibility in choosing contractors: you can hire one company for assessment and a different company for remediation, but both will hold the same license type, and both are qualified for either task.

What This Means When You Hire

1. Hire a licensed mold remediation contractor to inspect your property and write a remediation protocol. Even though their license authorizes both assessment and remediation, they are acting only as assessor on your property.
2. Hire a different licensed mold remediation contractor to perform the physical remediation work. This contractor must be different from the one who did your assessment — the COI rule prohibits the same company from doing both on the same property.
3. Schedule clearance testing after remediation is complete. The assessor (or an independent licensed contractor) should verify mold levels have returned to acceptable thresholds.

Badges on Our Directory Listings

Because Louisiana's single license type covers both assessment and remediation, all Louisiana contractors in our directory are shown with both the Remediation badge and the Inspection & Assessment badge. This accurately reflects what their license authorizes them to do — the contractor can perform either role on different properties, just not both roles on your specific property.
