Legislation will allow for the creation of new in-law units - which are the most affordable type of non-subsidized housing - in unused spaces such as garages, large storage areas, and basements, in order to help address housing crisis

San Francisco, CA - Today the Board of Supervisors passed Supervisor Scott Wiener's legislation to create new in-law units in the Castro. The legislation will allow property owners in the Castro neighborhood to add one or two in-law units (depending on the size of the building) in order to increase the neighborhood's housing supply. Units placed in rent-controlled buildings will be rent-controlled, meaning that the legislation will allow for the creation of new rent-controlled units.

"I'm proud and excited that this legislation to expand our housing supply will become law," said Supervisor Wiener. "Solving our housing affordability crisis requires a variety of approaches and getting these units built in the Castro will be a great step towards creating new affordable homes. These units - which will generally be on the ground floor -- will be good options for seniors and the disabled, who have mobility issues. I'm also excited that we will be creating new rent-controlled units for the first time in over 30 years." 

The legislation allows for new in-law units on any parcel within 1,750 feet of the Castro Neighborhood Commercial District, which stretches, approximately, from Hill Street on the south to 14th Street on the north and Dolores Park on the east to Market Street at Clayton on the west. Within this area, any parcel currently zoned residential may add one or two in-law units beyond density limits, depending on the size of the building. A building that has 10 or fewer units can add one unit, while a building with more than 10 units can add up to two units.

Other provisions of the legislation include: the units must be built within the envelope of the existing building (ie, no physical expansion of the building's height or bulk), units cannot exceed 750 square feet and will typically be a minimum of 220 square feet, and units cannot be created by subdividing a current unit. Each unit will be required to have its own kitchen and bathroom. Additionally, the Zoning Administrator and the Department of Building Inspection will have the authority to relax certain zoning and Building Code provisions as necessary to authorize these units and make them feasible.
