During the 2008 legislative session, the General Assembly passed The Maryland Mold Remediation Services
Act. This law is printed in Title 7 of the Home Improvement Law, contained in the Business Regulation Article of the Annotated
Code of Maryland.
This law requires that any company or firm that provides mold remediation services on residential property in Maryland
obtain a license to provide mold remediation services. In addition the law requires that each employee who provides mold
remediation services be certified by an accreditation body as a microbial remediation technician or supervisor, whichever
is applicable. This license is to be issued by the Maryland Home Improvement Commission (MHIC), an agency within the Department
of Labor, Licensing and Regulation (DLLR). The license to provide mold remediation services is different from the MHIC
license for a contractor, subcontractor, or salesperson.
This law was scheduled to take effect on July 1, 2013. However, due to budget constraints, the DLLR has postponed the
implementation of the Maryland Mold Remediation Services Act indefinitely. Nonetheless, the Commission plans to draft and
propose regulations in support of the Act; the public will have an opportunity to comment on the proposed regulations before
they are promulgated. If you would like a copy of the proposed regulations, once published, please send an email request to
Therefore, until the Mold Remediation Services Act is implemented, a mold remediation contractor who only performs
"cleaning" type services (such as cleaning ventilation systems or applying chemicals to kill mold), would not be required
to hold a MHIC license.
However, any mold remediation contractor who performs structural renovations to a house in the course of a mold
remediation project (for example, tearing out and rebuilding walls, repairing drywall, replacing floors, etc.) is required
to hold a MHIC contractor license. Likewise any contractor that currently holds a MHIC contractor or subcontractor license
and who also provides mold remediation services on residential properties will be required to hold both the contractor and
subcontractor license and the license to provide mold remediation services.
