SF Mayor Breed racing to keep approvals moving for 3,400 housing units

San Francisco Mayor London Breed introduced legislation Tuesday that she hopes can keep more than 3,400 proposed housing units — nearly 500 of them permanently affordable — from disappearing into the maw of the city’s development regulations.

In the midst of a punishing housing shortage, 24 proposed developments are at risk of missing an early December deadline for securing building permits, the final step before construction can begin.

If they miss the deadline, the developers would be forced to build more affordable units into their projects than the city had required of them. The fear is that the developers may abandon the housing in favor or other uses, such as retail.
