Lab pathway

Air sampling and third-party analysis

No license required

Mold assessment and air sampling are completely unregulated in Louisiana — the third-party lab model operates freely.

  • 01Louisiana has no licensing, certification, or registration requirement for mold assessment, inspection, or air quality sampling.
  • 02Collecting spore trap samples and sending them to an AIHA-accredited third-party lab for analysis requires no state credential of any kind.
  • 03Only mold remediation on projects valued at $7,500 or more requires a contractor license (LSLBC Mold Remediation Contractor).
  • 04There are no disclosure requirements, educational prerequisites, or insurance mandates for the assessment or sampling side of mold work.
  • 05The Spore Trap collection → AIHA-accredited lab analysis → report rendering pathway is fully permitted without any Louisiana state credential.

This summary addresses the spore-trap collection, accredited third-party lab analysis, and report-rendering model for Louisiana. Verify the current interpretation with the responsible state authority or qualified counsel.

Before accepting work

Additional notes

  • 01Louisiana is one of the most favorable states for starting a mold inspection or air quality testing business — assessment and sampling are completely unregulated.
  • 02The assessor/remediator separation rule only matters if you plan to offer both services — you would need separate licensed entities for each role.

After you verify the rule

Keep the requirements visible as the job moves.

Mold Inspector can organize scheduling, field documentation, reports, quotes, and invoices. It does not replace required training, licensing, sampling protocols, legal review, or professional judgment.
