The cause of the fire was still under investigation, but Campbell said it's suspicious in nature, and was started in one of the 16 units of the wing.
Firefighters from Benicia, Crockett, American Canyon and Fairfield assisted at the scene, and provided city coverage.
It took firefighters about 35 to 40 minutes to put the fire under control, Campbell added.
One firefighter sustained first- and second-degree burns fromthe fire, and has since been treated and released from the hospital, he said.
No residents were reported injured, but about 25 to 30 people, including at least six children, from all 16 units were displaced.
One unit was destroyed by the blaze, while four other units sustained fire, smoke, heat, water and other damage, Campbell said.
The apartment complex was also the scene of a Friday afternoon fatal shooting of a 26-year-old Vallejo man. However, police said they do not believe the two incidents were related. The fire was in a different wing of the complex.
