PLAINVILLE, Mass. (WPRI) — An investigation is underway following a fire at a condominium complex in Plainville, Massachusetts, late Tuesday night.

Crews responding to a report of a mulch fire on Messenger Street around 11:45 p.m. found heavy fire and smoke coming from two units of Huckleberry Hill.

Tenants from all 10 units were able to safely make it out of the building, according to Fire Chief Richard Ball.

Firefighters began an aggressive exterior attack until they were able to go inside, but were eventually forced back out by the fire and had to continue fighting the flames from outside, Ball said.

“The fire was inside the wall and void space inside the building,” he explained. “It went quickly to a second alarm, third alarm, and fourth alarm for manpower, fire got into all the vacant void spaces inside.”

No injuries were reported but the owner of the building was transported from the scene for stress-related injuries.

The fire was under control by 1 a.m. but crews remained on scene to make sure they didn’t miss any spots.

Officials say 21 adults and eight children were displaced by the fire. Two units were heavily damaged and the Red Cross was called in to assist those families.

Ball hopes to get at least eight units back in by the end of the day.

Plainville firefighters got help from at least 12 neighboring towns including Walpole, Franklin, and Cumberland.
