Three families were displaced after the 11:30 a.m. crash at a multiunit, two-story building at 4495 Central Ave., Fremont fire Capt. Diane Hendry said.
The man, driving a white, extended cab Chevrolet pickup truck, is suspected of being under the influence of alcohol and marijuana when he drove into the building, police said.
During the impact, some of the building's residents were inside the home, including one person in an apartment on the bottom floor and several upstairs, officials said.
None of the residents were injured, Hendry said. But the driver of the truck was taken to a hospital to be treated for minor injuries.
