The Board of Plumbers makes every effort to include on this website all relevant information pertaining to the licensing and regulation of Plumbers and Med Gas Endorsees in Montana.

 

  • During the 2025 Legislative Session, the Montana Legislature passed HB 276, impacting how the Department of Labor & Industry serves legal notices.

    What’s Changing: All licensees and applicants are required to provide the department with their current mailing address and any change of address within 30 days. Individuals may consent to electronic service of legal notices by providing a current email address and updating within 30 days of any change.

    All applications and renewals with the department will include the following:

    1. Three additional attestations covering the individual’s responsibility to provide a current mailing address and participate in the complaint and contested case processes.
    2. One question asking the individual if they wish to consent to receive service of Notice of disciplinary matters by email. Once the individual has consented to electronic service, they will not be asked to consent again in future transactions with the department.

    If you have any questions or concerns, please contact us at (406) 444-6880 or dlibsdhelp@mt.gov.
