Nine people were left homeless Friday night after fire heavily damaged a four-unit residential building in the Lower Village in Kennebunk.

The fire at 170 Port Road was caused by a chimney fire, said Jeff Rowe, chief of Kennebunk Fire & Rescue. He said the top floor of the building was damaged by the fire, and the bottom two floors had extensive water damage.

Rowe said eight people were home at the time of the fire, but nobody was injured. He said the Red Cross and a local business are providing temporary housing.

Firefighters responded at 9:19 p.m., and the scene was cleared at 2 a.m. Saturday.

Fire departments from Kennebunkport, Wells and Arundel provided assistance at the scene, and departments from other towns in the region provided backup.

The Lower Village is a section of Kennebunk just across the river from Dock Square in Kennebunkport.
