While SB 10 allows cities to opt-in to streamlining housing development in certain areas, no California city has officially adopted it. San Diego, for instance, initially considered implementing SB 10 but later removed it from their Housing Action Package. SB 10, which focuses on "missing middle" housing in transit-rich areas, is not mandatory and requires local legislative bodies to pass a resolution to adopt it, according to California YIMBY.
Here's a more detailed explanation:
SB 10 allows for streamlined upzoning:
It enables cities to rezone certain areas, particularly those near transit, to allow for denser housing development, specifically up to 10 residential units per parcel.
Local control remains key:
Despite allowing for this streamlined process, SB 10 does not force cities to adopt it. Local legislative bodies must vote to opt-in to the program, says California YIMBY.
San Diego's experience:
San Diego was initially considering SB 10 as part of its Housing Action Package 2.0. However, due to concerns about the bill's impact on historic resources and community character, it was ultimately removed from the package.
SB 10 is not mandatory:
The key takeaway is that SB 10 is an optional tool for cities to address housing needs. No city is required to implement it, and it's up to each individual city council to decide whether or not to adopt it.
