For the second time in under a day, a home caught fire in Antioch early Tuesday morning, according to Contra Costa County Fire Protection District officials.
On Monday, firefighters responded to a two-story home located at 406 H St. at 1:21 p.m. on reports of a fire on the second floor. Crews were able to extinguish that blaze.
Around 4 a.m. Tuesday, firefighters again were called to the residence on reports of another fire. Once on scene, firefighters were able to knock down the fire in about 45 minutes, fire officials said.
According to Fire Marshal Robert Marshall, the home was very old and the methods used in constructing it are no longer allowed because of the way flames can remain hidden in concealed spaces.
Marshall said the second fire was likely caused by the first one.
The cause of the first fire is still under investigation.
The damage was initially estimated at $550,000 from the first fire, and an updated estimate after the second fire was not immediately available.
No injuries were reported in either fire.
