Not in SF proper... I'm a native san franciscan that grew up in the mission in the 90's, and virtually every native san franciscan I've ever met has been a renter. I only had like 1 friend in high school whose parents actually owned a duplex in noe valley, but other than that, pretty much everybody was in small apartments. I think this is the reason why a lot of the "if you wanted a stable living situation, you should've bought a home" type arguments aggravate a lot of the anti-gentrification people in SF...
