Woodruff Block

Why it's listed
Standing at the northwest corner of West First and West Cayuga streets in Oswego, this four-story commercial building dates to about 1840. It has load-bearing masonry walls, an eight-bay brick facade on West First Street, a seven-bay facade on West Cayuga Street, and a rounded corner joining them. The ground floor has cut stone columns and lintels, with some slender cast iron columns added in the late nineteenth century. Greek Revival details include Doric capitals, rusticated stone panels and corbelled brick parapets shaped like classical entablatures. The building reflects Oswego's growth as a port after the 1828 canal opened, when this area filled with warehouses, chandleries and shops. Early occupants included the attorney Leander Babcock, and later uses ranged from fruit wholesaling and knitting to footwear, car sales and retail. Steel columns and beams were added to the floors between 1900 and 1930. Fires and demolition have removed most of the surrounding district, leaving this one of the few reminders of the city's port-era commerce.
Significance in brief: The building is tied to Oswego's rise as a major Great Lakes port in the early and mid-nineteenth century, after the Oswego Canal opened in 1828. It is also a rare surviving example of Greek Revival commercial architecture in the city. Little else remains of the nineteenth century waterfront commercial district.

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.
