Fire crews in North County responded to a house fire and reports of heavy smoke Tuesday night.
The fire broke out inside the main entry of a home at 300 Beaumont Court in Vista, and crews were assigned to "fast attack" and search the interior of the home first, authorities said.
Luckily no one was in the home.
Officials said the fire appeared to be burning inside the interior walls of the house, even after the exterior flames had been put out.
San Diego Gas and Electric was requested to inspect both the gas and the electrical and to assist with utilities.
The cause of the fire is still unclear and an investigation continues.
