Welcome to the Montana Board of Plumbers

Due to the evolving COVID-19 situation in Montana, all Montana Department of Labor & Industry offices are closed to the public to protect the health and safety of our clients and staff.  Our services are available through remote delivery.  We are available to assist customers through our online public portal at EBIZ.MT.GOV/POL (Professional and Occupational Licenses) and EBIZ.MT.GOV (for Permits). For other services, please contact us via email at DLIBSDWEBHELP@MT.GOV or by phone (406) 841-2300.

Due to the COVID-19 health emergency, all board meetings will be held by conference call.  No outside participants or stakeholders will be allowed access in the building.  Please attend by phone.


Effective December 23rd, 2019, plumber examinations will be delayed on being scheduled until after February 3, 2020.  The current candidates that are scheduled with GITS on the 2012 UPC will be rescheduled with the new provider IAPMO.  The Department and the Board of Plumbers are transitioning to a new examination provider, along with updating the examinations to the 2018 UPC.  The 2018 UPC examinations won't be utilized until after March 15, 2020 along with scheduling Practical Examinations.  Those making application after that date will test on the 2018 UPC.  Once the transition has occurred, any currently scheduled candidates will be sent a new admission letter with directions on scheduling your examination with the new provider IAPMO and details on the testing information.

Thank you for your patience during this transition period.


As of December 7, 2019, the State of Montana has adopted the 2018 Uniform Plumbing Code (UPC),  the 2017 NFPA 70 (2017 NEC), the 2018 International Existing Building Code, the 2018 International Mechanical Code, the 2018 International Fuel Gas Code, the 2018 International Building Code, the 2018 International Residential Code, and the 2012 International Energy Conservation Code.  Official versions of these administrative rules will not be available until published by the Secretary of State.  You may check for updated publishing at: http://bsd.dli.mt.gov/Building-Codes-Permits/current-codes

You may also review additional information on the code amendments at the Building Codes Web page at bsd.dli.mt.gov/building-codes-permits.

Lookup Licensed Individual

Licensee Lookup System

This site is a primary source for verification of license credentials.

The Montana Department of Labor and Industry, Business Standards Division, presents Licensee Lookup information as a service to the public. The Division relies upon information provided by licensees to be true and correct, as required by statute. It is an act of unprofessional conduct for a licensee knowingly to provide erroneous information to the Division.

The Department of Labor and Industry makes no warranty or guarantee concerning the accuracy or reliability of the content of this website. Assessing the accuracy and reliability of information obtained from this website is solely the responsibility of the user. If you have questions regarding information found within this Licensee Lookup website, please contact the specific licensing board directly.

Please note that some disciplinary actions against licensees may not appear immediately on the website. Appeals, effective dates of orders and other administrative processes may delay posting on the website. Please contact the specific licensing board directly if you require discipline information that occurred prior to July 1, 1996.

All of the Statutes and Rule listed here are applicable to this board.

Statutes are laws passed by the Legislature. All changes in statutes must go through the legislative process and be passed into law before they become effective.

Administrative Rules pertaining to plumbing licensure are written and adopted by the Board of Plumbers. The Board writes rules in order to administer the laws over which the Legislature has given the Board authority. Rules can be changed by going through the rule-making procedure. They do not go through the Legislative process. The Board of Plumbers continuously reviews rules to determine needed changes.

There is a possibility, however, that the content may vary from the official version. In addition, the format has been changed for viewing on this web site. A copy of the official ARM in official format can be obtained from the ARM Bureau of the Office of the Secretary of State, by emailing at SOSARM@mt.gov
