The high school went through several changes throughout the 1990s. In December 1991, maintenance crews installing a heating system sparked a fire that damaged the guidance area and several science labs, which were later remodeled. The school also caught fire two years later after an explosion occurred in the school's main electric panel. While a new wing of classrooms was added to the high school in 1996, a new two-story building was opened in 1998 adjacent to the existing high school, with the old high school building housing ninth and tenth graders known as the "9/10 building". At the same time, the middle school went back to housing the seventh and eighth graders.
