ROCKFORD, Ill. (WTVO) — Fire crews were called out to fight a fire at Oleson Plaza, a senior-living high-rise apartment building at 511 N. Church Street on Friday afternoon.

The call went out at 5:43 p.m.

First arriving units were able to see smoke coming from a 3rd floor window.

Officials said the small apartment fire had been extinguished by the building’s sprinkler system. The occupant of the apartment was not present at the time of the fire.

Fire officials deemed the cause to be “a result of careless smoking.”

The cost of the fire was estimated at $65,000.

Olesen Plaza is a 14-story high rise that opened in 1973 and is currently owned by the Rockford Housing Authority. The building contains 151 units and, at 133 feet tall, is the 9th tallest building in Rockford.
