The District of Columbia introduced a bill that would create new licensing requirements for glaziers and glazing contractors in the city.
District of Columbia Bill 422 (2025) aims to amend Chapter 28 of Title 47 of the District of Columbia Official Code to establish licensing standards and certification requirements for glaziers and glazing contractors. The bill also would add two members representing glaziers and glazing contractors to the Board of Industrial Trades.
The bill’s introduction follows Oregon’s bill requiring the North American Contractor Certification (NACC) and Architectural Glass and Metal Technician (AGMT) credentials for certain taxpayer-funded projects. It was signed into law on June 11, 2025, and goes into effect on July 1, 2027. Oregon is the second state, after Rhode Island, to mandate national certifications for public glazing projects.
“The Architectural Glass and Metal Certification Council (AGMCC), the parent organization of the AGMT glazier certification, has supported legislation to improve the quality of glazing in multiple regions of the United States,” says Jeff Dalaba, director of program development at AGMT. “Currently, there is approved legislation and or regulatory requirements in place for Rhode Island, Oregon and multiple counties of New York (Broome, Monroe, and Onondaga) that establish criteria for glazing installer certifications. It would be a welcome recognition of the value of the certifications to have further recognition through legislation in the District of Columbia.”
Oregon’s bill requires a contractor, as a condition of receiving public funds, to install, repair or remodel a fenestration product or system in a public building, to hold the NACC certification and to have at least one employee hold the AGMT credential. Rhode Island’s bill requires certain public works renovation and new construction projects to be completed by NACC-certified companies. The bill adds that after Jan. 1, 2026, 25% of crews must be AGMT-certified, and after Jan. 1, 2027, 50% of crews must be comprised of AGMT-certified individuals.
If passed, D.C.’s bill, known as the Glazier Licensing Standards and Certification Act of 2025, would introduce a licensing and certification process for glaziers and glazing contractors. This requirement does not currently exist in D.C.
“Most regions of North America do not have any formal licensing or requirements for glazier qualifications for projects,” notes Dalaba. “AGMT has worked to fill that need for the industry with a comprehensive, ANSI/ANAB accredited certification that provides hands-on verification of the knowledge, skills and abilities of glaziers for glazing projects.”
To become licensed in D.C., an individual glazier would be required to either pass the AGMT certification exam or complete a registered apprenticeship program with the Bureau of Apprenticeship Training, United States Department of Labor, the District of Columbia Apprenticeship Council or an equivalent state’s apprenticeship council. A glazing contractor would also need to employ a minimum of three licensed or temporarily licensed glaziers and satisfy specific bonding and insurance requirements.
The AGMT certification is North America’s only credential for architectural glass and metal technicians. It is an independent, third-party assessment of a glazing installer’s knowledge, skills and abilities through written and hands-on evaluations. The NACC program evaluates glazing contractors through onsite and annual audits in five areas, including business practices, safety, quality management, contract administration processes and glazing processes.
