The city added that the Federal Aviation Administration had been notified of the plane crash.
Keene Police Capt. Steve Tenney said emergency crews were called to an explosion and fire, subsequently learning a plane had gone into the building.
"At this time, we don't know about the occupants of the plane, how many there are," Tenney said.
He added that the aircraft was a small, single-engine plane.
"We can confirm that there was a plane into the building and that no one in the house itself were injured, so there were no ground injuries, there were no transports."
Earlier Friday evening, Swanzey police said on Facebook that people are being asked to stay clear of lower Main Street in Keene.
"First responders are on scene of a plane crash with building fire," they said.
