Waterbury, CTInc. 1686
Waterbury is one of Connecticut's largest cities, historically known as the "Brass City" for its dominance in brass manufacturing. The city's industrial peak built a dense urban core of mill buildings, commercial blocks, and the multi-family housing that surrounded the factories. The Naugatuck River runs through the center, and the city's hillside topography creates dramatic elevation changes between neighborhoods.
For property professionals, Waterbury is an affordable urban market with a dense, older housing stock, significant industrial and commercial property, and the Naugatuck River flood zone through the center. Building condition varies enormously, and the industrial legacy brings environmental screening considerations.
