We believe this is a Folding Door Spider in the genus Antrodiaetus, and it really looks to us to resemble the female Antrodiaetus gertschi that is pictured on BugGuide by a single sighting in Northern California.  You can try browsing through the genus page on BugGuide to see if some other species more closely resembles your individual.
