First - Happy Valentine's Day!
You've probably heard about 2 proposals that aim to increase the housing supply in SF. Supervisor Chiu will be proposing in-law amnesty during the next month or so. It will first be reviewed by the Board of Supervisors.
In addition to that, and having nothing to do with existing in-law units, Supervisor Wiener is proposing a law that would allow for an additional unit to be created within the existing building envelope of a home, so long as it is not created out of existing habitable space.
The law would not be citywide. Supervisor Wiener is proposing a trial area. The boundaries would be generally - Dolores to the east, 14th St. to the north, Market to the west and 22nd St. to the south.
