The Dual Contracts, which were signed on March 19, 1913, were contracts for the construction and/or rehabilitation and operation of rapid transit lines in the City of New York. The contracts were "dual" in that they were signed between the City and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company), all working together to make the construction of the Dual Contracts possible. The Dual Contracts promised the construction of several lines in Brooklyn. As part of Contract 4, the IRT agreed to build a branch of the original subway line south down Seventh Avenue, Varick Street, and West Broadway to serve the West Side of Manhattan.[3][4][5]

The construction of this line, in conjunction with the construction of the Lexington Avenue Line, would change the operations of the IRT system. Instead of having trains go via Broadway, turning onto 42nd Street, before finally turning onto Park Avenue, there would be two trunk lines connected by the 42nd Street Shuttle. The system would be changed from looking like a "Z" system on a map to an "H" system. One trunk would run via the new Lexington Avenue Line down Park Avenue, and the other trunk would run via the new Seventh Avenue Line up Broadway. In order for the line to continue down Varick Street and West Broadway, these streets needed to be widened, and two new streets were built, the Seventh Avenue Extension and the Varick Street Extension.[6] It was predicted that the subway extension would lead to the growth of the Lower West Side, and to neighborhoods such as Chelsea and Greenwich Village.[7][8]

Houston Street opened as part of an extension of the line from 34th Street–Penn Station to South Ferry on July 1, 1918.[9][10] Initially, the station was served by a shuttle running from Times Square to South Ferry.[11][12] The new "H" system was implemented on August 1, 1918, joining the two halves of the Broadway–Seventh Avenue Line and sending all West Side trains south from Times Square.[13] An immediate result of the switch was the need to transfer using the 42nd Street Shuttle in order to retrace the original layout. The completion of the "H" system doubled the capacity of the IRT system.[7]

The city government took over the IRT's operations on June 12, 1940.[14][15] On August 9, 1964, the New York City Transit Authority (NYCTA) announced the letting of a $7.6 million contract to lengthen platforms at stations on the Broadway—Seventh Avenue Line from Rector Street to 34th Street–Penn Station, including Houston Street, and stations from Central Park North–110th Street to 145th Street on the Lenox Avenue Line to allow express trains to be lengthened from nine-car trains to ten-car trains, and to lengthen locals from eight-car trains to ten-car trains. With the completion of this project, the NYCTA project to lengthen IRT stations to accommodate ten-car trains would be complete.[16]

This station was renovated in 1994 by in-house forces.

All fare control areas in this station are at platform level and there are no crossovers or crossunders. On both sides, a turnstile bank leads to a two staircases going up to West Houston and Varick Streets, either western corners on the South Ferry-bound side and either eastern corners on the Bronx-bound side. Only the Bronx-bound side has a token booth; the South Ferry-bound side is unstaffed.[21]

Both platforms have an unstaffed secondary fare control area towards their south ends. Two high entry/exit turnstiles and one exit-only turnstile leads to two staircases going up to Varick and King Streets, either western corners on the South Ferry-bound side and either eastern corners on the Bronx-bound side.[21]
