Firefighters and police arrived on scene and battled a blaze that broke out, and evacuated surrounding businesses, Wells said.
The fire damaged the warehouse, which appeared to contain sewing machines and textile stock. The building was occupied by Michael Nicholas Designs, a furniture upholstery manufacturer, according to a sign on a door.
Ten people were taken to the hospital, while eight were treated and released at the scene, police said.
It was not immediately known what type of plane it was or whether those injured were in the aircraft or on the ground, Wells said.
The flight-tracking website FlightAware shows a four-seat, single-engine aircraft crashed about a minute after takeoff.
Security camera footage from Rucci Forge, a wheel manufacturer across the street, shows a fiery explosion and a large plume of black smoke as the plane appeared to dive into the building tilted on its side.
The plane crashed near the Fullerton Municipal Airport, a general aviation airport in Orange County that is about 10km from Disneyland.
Fullerton is a city of about 140,000 people some 40km southeast of Los Angeles.
