San Francisco implemented a time cutoff for its rent control, which covers places prior to 1979. That said, the increase limit is much less than the CPI, about 0.5X, So covered rents grow much slower than inflation. As such, there is a pretty big secondary market where leaseholders make money subletting rent controlled places. I know about a dozen people who have moved to other cities and states, but sublet in SF making thousands.
