State Senator Bill Dodd, who represents the area, told reporters that the gunman was a member of the Pathway Home, a program for veterans suffering from post-traumatic stress disorder, or PTSD. The hostages were believed to be employees at the Yountville Veterans Home who worked with the suspect in the Pathway program, he said.
Larry Kramer told Reuters his wife worked at the facility, the largest of its kind in the country and home to about 1,000 veterans about 50 miles (80 km) northeast of San Francisco.
"She's quite shaken up. She's in a locked down building," Larry Kramer told Reuters after speaking by phone to his wife who is safe but sheltering in place. "She said it was just very calm. He walked in with a rifle. She was face to face with him when he walked in."
Hostage negotiators from three different agencies were trying to make contact with the suspect, the California Highway Patrol said.
"Gunfire was exchanged. It's not known at this time how many rounds were exchanged, but I am happy to report that at this moment there have been no injuries," CHP spokesman Chris Childs told reporters.
The standoff comes less than a month after a former student with an assault-style rifle killed 17 people at a Florida high school. The massacre touched off a student-led drive for new restrictions on gun ownership to prevent the kind of mass shootings that have become epidemic in the United States.
A Napa Valley sheriff's deputy arrived at the scene within four minutes of the first reports of gunfire, and exchanged shots with the suspect, Sheriff John Robertson said. Authorities know his identity, he said, though it has not been disclosed yet.
A resident of the home, identified as Rod Allen by the local CBS affiliate KPIX, said the gunman took the hostages after allowing some people at a party to leave. He fired about 30 shots, the resident said.
