Since 1896 our members have proudly served the Hudson Valley. Our local is made up of 7 local unions consolidated over the last 100 years to form Local 21.  Our charter and history date back to 1997.

The members and leaders of United Association, Local 21, would like to welcome you to our website where you can find a great deal of information about us.  The Plumbers, Steamfitters, HVAC and Refrigeration service technicians of Local 21 work on projects of all shapes and sizes.  We are actively working at the iPark in Fishkill, Corporate Parks throughout our territory, and on high-rise luxury apartment buildings such as those in New Rochelle and White Plains.  We also work at public and private educational institutions such as elementary schools, high schools, colleges and universities.  You’ll also find us working at industrial and commercial facilities as well as residential developments and private homes.

Our highly skilled workforce makes Local 21 vital to many industries throughout the Hudson Valley.  We are over 1200 members strong and growing.  We pipe a 5-county-area within our jurisdiction and we’re always looking for the best and the brightest that our region has to offer.  You can click on the Organizing and Apprenticeship pages to learn more about how to join our great organization.
