The proposed ordinance which would allow the construction of new “Accessory Dwelling Units” (i.e., In-Law Units) in the Castro and within 1,750 feet of the District’s boundaries could be approved by San Francisco’s Board of Supervisors this afternoon.
The new units would need to be constructed within an existing building’s envelope, would not be allowed to exceed 750 square feet in size, and could not use space from an existing dwelling unit in its construction. In-Laws would not be permitted in areas zoned for detached single-family homes, but they would be allowed in existing auxiliary structures.
And while newly created, the units would be subject to Rent Control if the existing building or any of the units within the existing building are currently subject to Rent Control.
A back of the envelope calculation estimated a theoretical maximum of 1,545 units could be constructed in the neighborhood under the terms of the ordinance, but the expected number of units to be constructed under the ordinance is closer to 400 (at most).
