Licensing
Do you need a license in Columbia?
Licensing for mold remediation work is set at the state and local level in Maryland, and Columbia may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: Mold licensing is taken seriously in several states, and some, such as Florida, Texas, and Louisiana, require a specific mold license, so accuracy here matters. Maryland's own approach to mold contractor or remediation licensing can change, and related work may intersect with MHIC contractor rules; do not assume you are exempt. Your NISCR MRT certificate is a professional credential, not a government license, so you must verify current Maryland state and local mold remediation licensing requirements before performing paid mold work.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
