UA Local 430 is the result of the 1997 merger of locals 205, 351, 397 and 767. The strong points of each local union were brought together to create a bigger, more efficient local to better serve our union members and signatories. With this consolidation, approximately 1500 UA-trained journeymen and apprentices were brought together as charter members of Local 430.
The UA Local 430 workforce takes pride in partnering with signatory contractors to deliver sophisticated piping systems, which are vital to the infrastructure of our community. Their signatories employ members of UA Local 430 in many construction industries – heavy industrial, commercial and residential sectors. They also specialize in HVAC service throughout the region, where cooling systems are very important to the economy.
