Sacramento here too, Carmichael actually...nothing. Still have the crack in the wall next to my computer from the '89 quake. I keep patching it everytime I paint and it keeps coming back.
Anything built in the last 40 years here really shouldn't have a problem because of the stricter building codes.
Guess that's been the problem in Florida, they waited a long time to tightened the building codes to better survive Hurricanes. CNN did a story on it, anything built before 1930, or after 1980 seemed to fair well because of the construction quaility, or after 1980, due to stricter building code. Just a couple of extra nails can mean the difference between no damage and no roof.
