Old State Mutual Building
Why it's listed
Built in 1870 at 240 Main Street, this three and one-half storey brick building is faced with dressed granite and shows the Second Empire style in a small downtown Worcester commercial block. Its three-bay facade is arranged around a shallow central pavilion topped by a low pediment bearing the date 1870. Ionic pilasters separate the first-storey bays, pilasters with moulded capitals mark the upper floors, and a mansard roof holds a single dormer with a segmented pediment. It is one of few such blocks remaining in the commercial district. The building was put up around 1870 through a real estate partnership between State Mutual Life Insurance Company and the Merchants' and Farmers' Fire Insurance Company. The two firms shared space until the late 1880s, when State Mutual took over the whole structure. The insurer moved to a larger headquarters at 340 Main Street after 1897. The building later served as a bank and offices, and the center bay was altered, probably in the 1950s.
Significance in brief: It is one of the few Second Empire commercial blocks left in Worcester's downtown and is described as one of the city's finest in that style, with a surprisingly formal design for so small a building. It was also built for State Mutual Life Insurance Company, an important local firm led by prominent citizens, as offices shared with another insurer.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
