The building contains several offices, including Ward construction, a dentist’s office, a CPA office and a counseling center.

Fire officials said the fire might have started on the roof. On Wednesday morning there was still smoke coming from the building.

No one was inside the building when the fire started and there have been no reports of injuries. One firefighter suffered a minor injury to his ankle.

A total of seven fire departments rushed to put out the fire at the building. Nearby homes and businesses were evacuated because smoke from the fire was a health concern.

It took two hours for fire crews to get the fire under control. The solar panels on the roof made it more difficult to get the blaze contained.

“They didn’t cause problems directly but because they’re there, in order to try to get behind them and get to the fire that was burning beneath them it created a little bit of trouble but there’s an access on the other side of it that we were able to get in there and work it out pretty well,” said Loveland Fire Division Chief Ned Sparks.

Fire crews continued to put out hot spots Wednesday afternoon. Heavy smoke is still visible in the surrounding neighborhoods. Firefighters are concerned if the fire reignites it could spread to nearby trees and other buildings. Crews will continue to monitor the situation for a few days.
