In January, the Pinnacle campus closed for more than two weeks due to weather-related repairs.
Built in 1984, the 10-story building requires extensive work following assessments that identified issues with its facade, accessibility and code compliance.
"There is no immediate safety concern, but we recognize that this timeframe is the best time to move forward," said Neil Vickers, ACC's executive vice president of finance and administration.
ACC will be able to reallocate students, faculty and classes to other campuses "with minimal impact to student services and class offerings," Vickers said.
Pinnacle classes scheduled for the summer term will be rescheduled at nearby ACC campuses.
Once the Pinnacle campus has closed, ACC will more thoroughly assess the building to determine the next steps, which may include repairs, renovation or expanding ACC's presence onto other parts of the 60-acre property.
The announcement of the Pinnacle closure comes as ACC develops and expands across Austin. Both the Hays and Round Rock ACC campuses will open new facilities this summer. The college district is also developing a new campus in Leander.
