On April 25, 1994, the largest high school arson in the United States occurred, which resulted in over $15 million in damages.

Around the time of the fire, the school's mascot was changed from the Braves to the Blaze to avoid stigmatizing and stereotyping Native Americans.

In 1997, District 191 bought the Diamondhead Mall and converted the top level into the Senior Campus to handle increasing enrollment.

Renovations included upgrades to the building's science labs, heating system, bathrooms and classrooms, and made the school more accessible to people with disabilities.

Lockers were replaced, the cafeteria was enlarged and reconfigured, and a larger, more open commons was created.

As a result of the increased number of students, Burnsville High School required an expansion, including classrooms, new fabrication and auto labs, a new gymnasium, and further renovations.
