The Santa Barbara City Fire Department responded to the fire about 5 a.m. in the 100 block of Harbor Way.
Harbor Patrol units were first on the scene and reported a vehicle fully engulfed. Firefighters arrived soon after, and a structure fire response was requested because of the exposure to nearby buildings.
Fire crews extinguished the blaze and kept exposure damage to a minimum.
The two city vehicles were parked about 5 feet from the museum. There was no interior damage to the museum, and no reported injuries.
Investigators believe the fire to be suspicious and are continuing to investigate.
