T.R. Keck & Sons is located at 101 Pecos Street, along the east side of the railroad tracks, opposite the row of commercial buildings along Front Street. Keck & Sons is a historic lumber and hardware business that occupies the two blocks south of Tilden Street between Market Street and the railroad tracks. The block between Tilden and Pecos contains a brick commercial building and attached lumber warehouse; this is counted as one resource. A large lumber warehouse also associated with Keck & Sons is located across Pecos Street to the south (discussed as a separate resource). Along the west side of the Keck & Sons blocks, a narrow street runs alongside the railroad tracks, built for the purpose of loading and unloading materials (designated on the Sanborn maps as Keck Street). The Keck & Sons business dates to 1893 and all of the associated buildings are from the historic period and have remarkable integrity.
