The incident started out as a structure fire.
One witness told NBC Bay Area at least one person who was in the burning building was taken away in an ambulance. No word yet on that person's condition.
Flames from the building then spread to the surrounding area and because of breezy conditions, the fire moved fast.
The fast-moving fire east of Danville prompted evacuation warnings for residents in the small community of Tassajara.
For a time, it did cause some tense moments for people in that rural portion of Contra Costa County.

The fire was burning further up into the foothills of Mount Diablo on private property but fire crews moved fast to contain it.
Contra County Officials issued an evacuation warning to residents but that has since been canceled.
During the warning, it prompted people to come out and keep an eye on their livestock in case they needed to evacuate them.
"A lot of fire trucks going up. Highway patrol was here from the very beginning to tell people they should or should not go up,” said Jayme Leigh, a resident in the area.
Cal Fire added that firefighters on scene will remain overnight establishing line around the fire and extinguishing hot spots.
