A house fire reported early Thursday morning at 1305 Bluff Ave. is believed to have been intentionally started, Racine fire officials said Thursday.
The building had been vacant and no injuries were reported, but the estimated damage was $50,400, fire investigators said.
Fire crews responding at about 1:30 a.m. Thursday extinguished fire in the kitchen before attacking fire on the second floor and then opening the second floor ceiling to extinguish fire in the attic.
Fire officials said the cause of the fire was incendiary and multiple points of origin were discovered during the investigation.
