That still applies to ~170k rental units, which constitute ~70% of the entire SF rental market.

Then great news, SF has built almost nothing since 1979, so you’re more likely than not to be covered!

Maybe I was being a cheapskate for keeping my rent under $2k per month when I lived there, but I never lived in an apartment that wasn’t rent controlled.

Last stat is read is 30% of units in SF aren’t under rent control. Don’t forget that condos (single unit) aren’t rent controlled even if older than 1979.

For better or worse, landlords have figured out they can renovate the unit (at considerable expense) in order to need get a new certificate of occupancy, which has the upside of considering it to be a 'new' unit for rent-control reasons.

I think rent control laws recently changed, in the last two years; in SF units older than 2005 now fall under standard rent control rules of ~2% per year or CPI increase, whichever is less. Values of properties built in 2005 recently dropped as a result. A couple years ago, rent controlled units were much older.

Source? Is it not 5%+CPI or 10% whichever is lower [0]?
