The same is true for Northern and Southern California. There's no official distinction. Calling the Bay Area part of Northern California places too much emphasis on the Los Angeles area. By analogy, saying that "North" begins at the Transverse Ranges is like saying that "Upstate" begins at Yonkers. Ridiculous.
I have found that (Bay Area subset of N. CA) is a very common misconception of people who have recently moved to the area.
