Rent control in San Francisco was a local ordinance in San Francisco.<p>There are many, many factors involved in dividing up an existing government into 6 new governments. Existing laws (namely Prop 13), significantly more abridged state Constitutions, existing contractual liability obligations (CALPERS &amp; CALSTERS retirement plans), and other contracts would likely be renegotiated in light of a different set of laws.<p>The only thing I particularly liked about this is that California&#x27;s population base is currently an outlier and our US Senate representation is vastly underpowered in proportion to other states. I don&#x27;t think the founding fathers knew that one state would have 69x the population of another state without the people voting to change either the state composition or the method of calculation of senators.
