An unattended candle was to blame for a three-alarm fire in Jamaica Plain on Saturday night that forced the evacuation of a 15-unit apartment building at 560 Centre St., fire officials said.

Although smoke quickly filled the building, the blaze — which began just after 10 p.m. — was contained to a single apartment on the first floor, according to Boston Fire Department spokesman Steve MacDonald, who said damage had been estimated at about $50,000.

The apartment’s three residents remain displaced but others in the building returned to their homes Saturday night, MacDonald said. One person was evaluated for minor injuries, he said.
