A home in the Legacy Farms neighborhood is “uninhabitable” after a fire broke out Thursday night.

Around 7:28 p.m., Hopkinton Fire Department dispatchers received multiple calls reporting a house fire at 1 Windsong Way. The HFD responded within minutes, assisted by crews from Ashland, Southborough, Upton and Milford. Hopedale covered the Fire Station while HFD crews responded to the fire.

“On arrival, we found a single-family home with heavy fire in the rear that extended into the soffits and attic,” said Hopkinton Fire Chief Gary Daugherty.

Crews knocked down the bulk of the flames quickly, but Daugherty said firefighters continued chasing hot spots in the home’s attic “for a good half hour before it was 100% under control.”

Two people inside the home were able to evacuate safely. Heavy structural damage caused by the fire rendered the home uninhabitable.

The State Fire Marshal is investigating the cause of the fire, though Daugherty indicated that it appeared to be accidental.
