Not all of these were volunteer houses but all originally started out as one firehouse, usually for an engine and then a ladder company was organized next door and a new firehouse was built. Examples of these are: E45/L58 @925-927 E. Tremont Ave. (1932/1974), Rescue 3's present quarters @ 451/453 E. 176th St. which was once E46/L27 (1895/1903), E64/L47 @ 1214/1220 Castle Hill Ave. (1908/1913), E73/L42 @ 655/661 Prospect Ave. (1900/1913), and E220/L122 @ 530/532-11th St. (1882/1907). There are also two former ladder company firehouses that were built directly behind engine houses with entrances & driveways on a different street; These ladder firehouses were later closed and the ladder companies moved into the engine houses directly behind them. They are E80 @ 503 W.139th St. and L23 @ 504 W.140th St. (from 1898 to 1918)[L23 was organized in 1898 and E80 in 1905], and E68 @ 1080 Ogden Ave. & L49 @ 1079 Nelson Ave. (from 1913 to 1947).
