I actually worked in the aftermath of the Loma Prieta Earthquake in '89 and am very familiar with a lot of the different type of damages that were sustained during and after that event. I'm in San Diego and only service the SF area after an EQ event as it is very expensive to mobilize our crews, transportation equipment, material and supplies for onesy twosey projects.
However, here is a link: http://www.earthquakesafety.com/retrofitting/seismic_retrofi to a local contractor in your area that looks like he knows what he's doing and has had some experience. I'm not recommending nor endorsing him. I've never met him. However, his website offers up a lot of very informative information. You could start by perusing his website and then give hims a call and see if he'd be interested in giving you an inspection and estimate for any required retrofitting.
That stated, I would alwo do a google searc for other earthquake retrofitting companies that are in the Bay area and get a few opinions and estimates. Good luck
