A two-alarm fire engulfed two connected homes in Southwest Baltimore's Irvington neighborhood Sunday afternoon, though no one was injured even after part of the building collapsed, city fire officials said.

The fire started in one of two houses in the unit block of Augusta Avenue, fire department spokesman Capt. Roman Clark said, and four adults in that home were alerted by smoke alarms and were able to get out safely.

No one was at home in the second house, where the fire spread, though a resident has been notified. The homes are connected, but it is not considered a duplex, Clark said.

Firefighters were called about 4:30 p.m. and a couple of hours later, the fire was contained but not out. Firefighters had to evacuate the building when a floor collapsed, Clark said. No firefighters were injured.
