Numerous additional buildings have been built on fort grounds outside of the fort. A row of wooden Victorian officer's homes was built in the 1880s. In 1937, these homes were completely refurbished and clad in brick by WPA workers. One home was restored in the 1980s to its original appearance. A Spanish–American War guardhouse, built in 1889, is in the center of the fort grounds. The guard house was restored in 1984. In 1890, a brick hospital was built, with a later addition in 1898. In 1905, a new guardhouse, still in use today, was built near the gate to the fort grounds. Around the same time, four barracks buildings for enlisted men were built, as well as a service club (1903), headquarters (1905), and post office. By 1928, duplex housing for senior NCOs. In 1939, more NCO houses were built in a row facing Jefferson Avenue.
