Southbury, CTInc. 1787
Southbury is a large suburban town south of Waterbury, with the Heritage Village planned retirement community as one of its most significant features. The Housatonic River and Lake Zoar form the town's western boundary. The housing stock includes Heritage Village's condominiums and townhouses alongside conventional single-family neighborhoods.
For property professionals, Southbury is a moderate market where Heritage Village creates a large, age-restricted community with its own market dynamics, and the Housatonic River/Lake Zoar create waterfront properties and flood considerations.
