O'Connor, James, Three-Decker

Why it's listed
Built around 1906, this three-decker at 23 Endicott Street in Worcester belongs to a row of similar houses facing Crompton Park in the Island neighborhood, a working-class area south of downtown. Its first owner, James O'Connor, was a gasfitter who lived in the building, and early tenants included blacksmiths, woodworkers and a machinist. Many residents were Irish and Swedish, later joined by Polish and Lithuanian families, and worked in nearby factories close to the railroad junction. The house is a late example of the Queen Anne three-decker, with a side-hall plan, hip roof, clapboard siding and wide bands of wood shingle wrapping the front bay. An ornate three-tier porch has lathe-turned posts, cut brackets and spindle friezes, and bracketed window caps and cornice brackets add detail. It was listed for its link to the neighborhood's development and for its well-preserved design.
Significance in brief: The nomination argues it is tied to the ethnic, working-class, multi-family Island neighborhood, especially the three-decker district around Crompton Park. It is also an unusually well-preserved and finely detailed example of the last Queen Anne three-deckers built in the city.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
