Crews found a fully involved detached garage with the fire extending towards the rear and roof of the house. The fire department said it brought the blaze under control at around 3 a.m. with hot spots extinguished into the early hours of the morning.
Fire officials said a man and one woman were not home at the time of the blaze.
Two dead dogs were removed by fire crews.
The house and detached garage are considered to be a total loss with a rough value of $400,000, the fire department said.
A fire investigator confirmed on Monday the blaze originated from an illegal open-air container without a screen, which quickly spread to the nearby garage.
The community relations section of the fire department will be conducting an “after the fire” follow-up in the immediate area surrounding the scene with informational packages delivered to over 100 homes, according to the fire department.
