In 1999 multiple fires were set at ABRHS. The first fire began near the gymnasium but was quickly extinguished. The second fire, a five-alarm blaze in the school auditorium, seriously damaged the auditorium and forced the evacuation of all 1,300 students and canceled school the following day. No students or staff were injured, but one firefighter was hospitalized after suffering from smoke inhalation.{{YouTube|VG_LKNkLOFE|"ABRHS School Fire"}} ABRHS underwent a $40 million renovation and expansion in 2005.{{Cite web|title=Acton-Boxborough Regional High School|url=https://schooldesigns.com/Projects/acton-boxborough-regional-high-school/|access-date=October 30, 2020|website=School Designs|language=en-US}}
