Gainesville firefighters responded to an apartment fire at about 6:30 p.m. Sunday.

The fire affected one apartment and spread to the attic at Forest Avenue Apartments, which is at the corner of Forrest Avenue and Bradford Street.

Firefighters were able to douse the fire by 7 p.m., said Gainesville Fire Chief Jon Canada.

People inside the residence alerted authorities about the fire and then left the home uninjured, Canada said.

The cause of the fire was unknown, as authorities are continuing their investigation.

Canada said the apartment sustained a lot of fire, smoke and water damage, but he didn't have a dollar estimate on the damage.

Further details weren't immediately available.
