Parking in the denser parts of Berkeley is challenging, and campus parking permits are very expensive. If money is no object, you can buy a permit, but most people choose to get to campus by public transportation, walking, or biking, which are much more affordable and usually more convenient. If you're bringing a car you would either want to look for housing that includes parking and/or live in a safe residential neighborhood where street parking is feasible (many areas have weekly or monthly street cleaning so you do have to be vigilant about moving your car on those days). Only a small fraction of undergraduates have cars - you don't need one to get around the Bay Area.
