A pair of overnight fires ripped through homes in Albany and Troy on Monday, displacing 30 people from their homes.

In Albany, a two-story wood-frame row house at 183 Sherman St. was heavily damaged by a blaze that broke out at 3 a.m., Albany Fire Department Battalion Chief Bill Moore said.

Six families live in the home and a building next door that also was damaged, but everyone who was home was able to escape safely, Moore said. Firefighters had the fire extinguished by 3:30 a.m.

"The damage to the home is very extensive," Moore said.

It's too early to tell whether the building will have to be razed, Moore said. A cause has not been determined, but the fire is not believed to be suspicious, Moore said.

The Red Cross said it is aiding the 14 adults and 13 children who were forced to leave their Arbor Hill homes.

In Troy, a home at 27 24th St. was badly damaged by a fire that began just after midnight, Troy Fire Chief Thomas Garrett said.

The fire was contained quickly, but the blaze tore through the two-story house and caused heavy damage. Three people live there, but there were no injuries, Garrett said.

Those forced out of the home are receiving help from the Red Cross as well.

The Troy blaze was the fourth major fire in the city since Friday. The Flavour Cafe at 230 Fourth St. was badly damaged by a suspicious blaze that broke out around 1 a.m. Friday. Investigators are still trying to determine the cause of that fire, Garrett said.

At 2:45 a.m. Friday, firefighters were called to 871 River St. for a small fire in a vacant building without electricity. Garrett said the fire was caused by a squatter using a candle.

Firefighters were still at the scene at 3:45 a.m. when a call came in for a blaze at 8 Cragin Ave., another vacant house with no electricity.

Garrett said the fires are not believed to be related. No serious injuries were reported in any of the blazes.
