Governor Gavin Newsom passed several pieces of legislation that ease regulations on the construction of accessory dwelling units (ADUs), sometimes colloquially known as “granny flats,” with the intent to spur ADU development in single-family zoned neighborhoods. Ben Metcalf, former director of the California Department of Housing and Community Development, said that single-family zoning is a primary barrier to housing affordability in California and that Governor Newsom cannot meet his administration’s housing goals without encouraging the state’s 9 million single-family homeowners to build ADUs. However, some opponents, such as Saratoga Mayor Manny Cappello, worry that an increase in ADUs will change neighborhood aesthetics and crowd residential street parking.
