Louisiana mold remediation license rules

What the law says

Louisiana licenses mold remediation (contractor classification) under La. R.S. 37:2150.1 and 37:2156–2158 (State Licensing Board for Contractors); La. Admin. Code tit. 46, pt. XXIX, §§ 301, 709. The trigger is jobs valued over $7,500. The text (La. R.S. 37:2150.1; LSLBC mold remediation classification): “A license is required when the value exceeds $7,500”.

Louisiana measures the job in dollars, not square feet. Set against Angi's published location ranges: attic ($1,000–$4,000), basement ($500–$3,000), crawl space ($500–$2,000) and bathroom ($500–$1,000) stay at or under $7,500; wall ($1,000–$20,000) and HVAC system ($3,000–$10,000) can cross it; whole house ($10,000–$30,000) starts above it.

Worked check: a $7,500 contract is at the line and not over it; $7,501 is over it. At Angi's $10–$25 per square foot, $7,500 is roughly 300 to 750 sq ft of affected surface (arithmetic, not a published figure), all of it in EPA's large category.

Assessor and remediator are kept apart: A mold remediation contractor may not provide both mold assessment and remediation on the same property, or hold an ownership interest in an entity that provides both, and must give a written report to the person paying for the work (La. R.S. 37:2158).

Insurance: Applicants present evidence of workers' compensation and liability insurance (La. R.S. 37:2156.1).

Training: Twenty-four hours of board-approved training in mold remediation and assessment (LSLBC mold remediation classification).

Who does not need a license

• A residential property owner remediating his or her own property.
• Owners or tenants remediating property they own or lease.

Before hiring

The free check is the state licensing board's public license lookup: confirm the company holds the license the statute names before work starts. EPA's homeowner guidance also suggests checking references and asking the contractor to follow EPA's remediation guide or the guidelines of professional bodies such as ACGIH or IICRC. Cost ranges for the work itself are on the mold removal cost pages.
