I found this on their website: Street parking at meters or on residential neighborhood blocks (2 hour limit, enforced regularly). Public garages located nearby at Portsmouth Square Garage, 733 Kearny St. (between Washington and Clay) and North Beach Garage, 735 Vallejo St. (between Stockton and Powell).
We do recommend using the parking garages just because street parking is so inconsistent and in general, finding street parking in SF is a challenge!
If you're really lucky you might find a spot that isn't metered in the more residential areas - but that is highly unlikely.
