At one point, heavy, black smoke could be seen coming from the area around 10:40 a.m. on Averill Street and Patton Street.
The police chief tells Eyewitness News a man in one of the houses realized there was a fire on his back porch.
Even though the fire department arrived within minutes, officials say firefighters had problems with water pressure.
They're now trying to determine the source of that low pressure.
The other homes that caught fire were damaged.
No one was hurt.
The cause of the fire is under investigation.
