MESA, Ariz. -- Investigators are trying to determine how a fire started inside a home on Sunday night.
The home is near University Drive and Lindsay Road.
Firefighters said one of the occupants of the home woke up and discovered the fire in the living room.
He alerted his two roommates. They grabbed their pets and got out safely.
"We had a really short response time. We're just literally a minute away and crews got on the scene. They cleared the house and they found the occupants in the backyard attempting to put the fire out," said Capt. Dean Morales with the Mesa Fire Dept.
The home has a lot of damage, much of it in the attic. It is uninhabitable.
