This ordinance amends the San Francisco Planning Code to merge the Corona Heights Large Residence Special Use District (SUD) into the Central Neighborhoods Large Residence SUD. The action expands the boundaries of the Central Neighborhoods SUD to include the former Corona Heights SUD and other adjacent lots. A key change is the reduction of the maximum gross floor area for dwelling units within the expanded SUD from 4,000 square feet to 3,000 square feet. The ordinance also clarifies that common spaces in multifamily buildings and parking garages are to be excluded from the gross floor area calculation. This legislative amendment aims to protect and enhance neighborhood character by providing a thorough assessment process for large single-family residences. The Land Use and Transportation Committee amended the ordinance on September 16, 2024, to implement these changes.
