Mold licensing varies widely by state. Only about 11 states plus DC have specific mold licensing programs. In states with licensing, a key distinction exists between mold assessors/inspectors (who evaluate mold conditions) and mold remediators (who remove mold). Many states with licensing require separate licenses for each role and prohibit the same company from performing both assessment and remediation on a single project to prevent conflicts of interest.

Regulatory Board
In states with mold licensing, license renewal is typically annual or biennial with continuing education requirements ranging from 8-16 hours. In states without licensing, national certifications (ACAC, IICRC, MICRO) have their own renewal cycles and continuing education requirements. Maintaining current certifications and insurance is essential for credibility and compliance.
Maryland licenses mold remediation (but not assessment) through the Department of the Environment. The remediation-only licensing approach means mold inspectors can operate without a state-specific license.
Maryland previously required mold remediation licensing under the Mold Remediation Services Act (2008), but the law was TERMINATED on July 1, 2019 due to budget constraints.
There is NO mold-specific license in Maryland as of 2026.
General contractor license through MHIC still required for construction work.
Voluntary national certifications (IICRC, ACAC, MICRO) recommended but not state-mandated.
