On September 16, 2021, in addition to signing SB9, Governor Newsom signed SB10. Considered a companion to SB9, SB10 addresses the local government’s ability to rezone existing parcels of real property to allow up to 10 dwelling units.

Similar to SB9, the state legislature passed SB10 and the governor signed it to promote the state’s efforts to create density in the state of California. SB9 and SB10 highlight the state government’s focus on housing density in the state. However, SB10 in contrast to SB9 places the ability to create housing density in the hands of local government.

In short, SB10 “authorizes a local government to adopt an ordinance to zone any parcel for up to 10 units of residential density per parcel, at a height specified in the ordinance, if the parcel is located in a transit-rich area or an urban infill site, terms are defined.”

More Important Facts About SB10

In addition, the local government must state they are adopting the zoning per SB10 and make a finding that increasing the density supports the furthering of fair housing.

It will also allow local governments to override existing zoning restrictions if the local governmental body implements SB10 zoning by a 2/3 vote. Local governments also do not have to get California Environmental Quality Act (“CESQ”) approval for the zoning change.

However, there are some limitations on the use of this bill by local governments. For example, once a parcel is zoned using this bill, the number of zoned units cannot be reduced. Also, parcels cannot be in a high fire zone, a designated open space, park, or recreation land. More importantly, the bill will sunset or end on January 1, 2029.

It is important to understand that per the language of the law, this would apply to the creation of rental or sale units. Also, this could potentially change a single-family zoned property through rezoning, allowing it to have multiple units. Of course, any potential development would have to meet existing design and permitting guidelines for the area.

Will it increase density?

It remains to be seen if local governments will utilize SB10 to increase density. But, it will likely garner opposition from local residents who are content with their present density. Much like SB9, those opposing SB10 must think past the superficial evaluation of the new law. The new law, while it may increase density, will create additional housing to combat the homeless problem. By increasing the supply of housing, the cost will necessarily be driven down, increasing housing affordability. The law is also environmentally friendly; the new zoning has to be a transit-rich area or an urban infill site, promoting mass transit.

The bottom line: we need to give SB10 a chance to see if it alleviates the issues the state has with housing.
