Throughout Fort Apache's military history, enlisted men were housed with their units south of Officers' Row. The first company quarters, completed in February 1871, were 18 by 20 foot log squad huts built in north-south rows across the area that would become the Parade Ground. The first two rows, with eight huts each, faced each other on the east end of the Parade Ground and housed a troop of cavalry in each row, and a third row of five huts was added 300 feet to the west to house infantry. These huts were cold, damp, drafty, overcrowded, and infested with bedbugs. The first company barracks built of milled lumber went up in the fall of 1875 as an L-shaped building located approximately where the school cafeteria now stands. In 1878, an adobe barracks begun in 1875 was completed and two more frame barracks were added. As the garrison grew, additional wings were added to two barracks in 1881 to make them U-shaped, a fifth wooden U-shaped barracks was constructed in 1882, wings were added to the other original barracks in 1885 to make them all U-shaped, and in 1889 two final adobe barracks were added at each end of Barracks Row, including the ruined structure still standing on the east end. After the military abandoned the post, the barracks were used by the Theodore Roosevelt School as dormitories, classrooms, a cafeteria, and for other purposes until new school buildings replaced them.
