Keeping testing and removal apart
- Florida: A remediator may not work on a structure where the same mold assessor or the assessor's company provided a mold assessment within the last 12 months (a certified Division I contractor is exempted). (s. 468.8419(1)(d), F.S.)
- Texas: “A license holder may not perform both mold assessment and mold remediation on the same project.” (Tex. Occ. Code § 1958.155(a))
- New York: “No licensee shall perform both mold assessment and mold remediation on the same property,” and no person may own an interest in both the assessment licensee and the remediation licensee on the same property. (N.Y. Labor Law § 936(2)–(3))
- Louisiana: 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)
- District of Columbia: DOEE declined to add a rule barring one licensee from both assessing and remediating the same project. (20 DCMR chapter 32 (final rulemaking))
Insurance, training and penalties
- Florida: Mold remediators must carry general liability insurance of not less than $1,000,000; mold assessors must carry general liability and errors and omissions coverage of at least $1 million. A first violation is a misdemeanor of the second degree, a second violation a misdemeanor of the first degree, and a third or later violation a felony of the third degree.
- Louisiana: Applicants present evidence of workers' compensation and liability insurance. Twenty-four hours of board-approved training in mold remediation and assessment.
Not covered here
- Maryland: Chapter 537 of 2008 created a mold remediation license under the Maryland Home Improvement Commission, but the 2016 Department of Legislative Services evaluation reports it was never implemented and recommended termination on July 1, 2019 if unfunded; current status not confirmed.

- Other states: Not reviewed in this release. A state-by-state survey from primary sources is pending; no state is described here as unlicensed.

Questions
Which states require a mold remediation license?
This site has read the licensing law of Florida, Texas, Louisiana, New York and the District of Columbia. Other states have not been reviewed yet, which is not a finding that they have no license.
Can one company test for mold and then remove it?
Florida, Texas, New York and Louisiana each bar it in some form; the state pages quote the rule. The District of Columbia's regulator declined to add such a rule.
Does Maryland license mold remediation?
A Maryland law created a license, but the state's own sunset evaluation reports it was never implemented and recommended that it end if unfunded. Its current status was not confirmed, so it has no page here.
