GRAND RAPIDS, Mich. (WOOD) — Firefighters responded to a fire at a Heritage Hill building in Grand Rapids on Thursday.

Crews were called around 7:30 p.m. to Morris Manor, located near the intersection of Cherry Street and Morris Avenue. A News 8 crew on scene saw firefighters fighting flames from the building’s third floor.

Morris Manor was built in the 1800s, according to the Grand Rapids Public Museum. It has since been converted into apartments.

Crews say only a small number of the Morris Manor’s 21 units were impacted.

“Honestly we made one heck of a knockdown. Got up to the third floor, knocked it down. Right now we have three units that are impacted out of the 21, people will be displaced there,” Grand Rapids Fire Department Battalion Chief Ed Braman said.

Braman said there were no injuries. A cat was rescued and given oxygen.

The cat “seems to be doing well,” Braman said.

The cause of the fire remains under investigation.
