The Director is also required to maintain a publicly accessible list of all qualified professionals and to set fees sufficient to cover the costs of running the program. Certifications from other states or independent bodies may be accepted if the Director determines they meet the District's standards.
Plain English — not legal advice.
D.C. Code § 8-241.03 requires that any mold assessment or remediation professional hired for residential properties in the District hold both a valid certification and a license recognized by the Director. Compliant property operators generally verify a contractor's credentials against the publicly available list the Director is required to maintain before work begins. Hiring an uncertified or unlicensed individual for this work would place the operator outside the requirements of this provision.

D.C. Code § 8-241.03 establishes that tenants in residential properties are entitled to have mold assessment and remediation work performed only by professionals who are both certified and licensed under District requirements. Tenants can consult the publicly available list of qualified professionals that the Director is required to maintain to verify whether a contractor hired by their landlord meets those standards. Those who believe work was performed by an unqualified individual may consider contacting the relevant District agency or a local tenant-rights organization to understand available options.
