Public transportation would be a bus (or drive) to BART and then BART to The City. I used to drive to BART at about 6:30 am - no traffic on highway 1 - and then take it to SF because the parking is so expensive. Pacifica is really close. It takes longer around 8 am because you end up fighting with the traffic going to Vallemar school. If you're commuting at off hours it's really fast.
Good luck in your home search!
