Ever hear of "tax liens?"
If the building owner can't pay up, he forfeits his property rights / the city confiscates the property.

Yeah
Although I think all of those vacant building owners should do a multi- billion class action lawsuit against SF for deliberately creating the social environment that caused their major losses of income, and also for crearing an environment where businesses would leave, creating building owners who can’t get new tenants in in a crime riddled city, and will use this self-created situation to steal their buildings under this targeted color of law through liens.
