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 to obtain a license to provide mold remediation services. In addition the law requires that each
employee who provides mold remediation services must 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 June 1, 2010. However, due to budget constraints, the DLLR has
postponed the implementation of the Maryland Mold Remediation Services Act until
July 1, 2013.
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
