IS SINGLE FAMILY ZONING OBSOLETE AFTER SB 9 AND SB 10?
California’s latest attempt to addressing the state’s housing crisis are Senate Bills (“SB”) 9 and 10, both of which were signed into law on September 16, 2021. Both bills allow for rezoning of single-family lots to accommodate multi-family housing.
SB 9
In short, SB 9 authorizes more than one residential unit on a property despite the property being otherwise zoned as single-family. While existing laws allow for accessory dwelling units (ADU) to be placed on a single-family lot, SB 9 ups the ante by allowing multiple dwelling units per lot. SB 9 allows for ministerial approvals of duplexes in a single-family housing zone and lot splits, provided that certain criteria like lot size and the location of the lot (must be in an “urbanized area” or “urban cluster”) are met. While the Coastal Act would still apply, SB 9 creates a statutory exemption for the California Environmental Quality Act (“CEQA”).
SB 10
Like SB 9, SB 10 is designed to remove the “red tape” in constructing multiple family dwelling units and ministerially authorize developments of p to ten-units or less in areas otherwise zoned as single-family housing. For example, the owner of an empty single-family lot may now receive ministerial approval to build a fourplex on your lot.
Implications of Both Bills
How will the strain on infrastructure be addressed? Placing 2, 4, 6 living units on a single-family lot will undoubtedly tax infrastructure like roads, electricity, water, and sewage.
What is the impact on Community Interest Developments, or HOAs? For example, if your CC&Rs require residences in the community to be “single-family” residences, this restriction now conflicts with SB 9 and SB 10. Must CC&Rs be amended? May additional units be assessed? How are HOAs to address the strain on common areas?
What are the tax implications of SB 9 and SB 10 on a single-family zoned property? While Proposition 13 likely protects owner-occupied single-family residences in single-family residential zones, those protections may not extend to tenant-occupied properties.
What, if any, discretion do cities or municipalities have with regard to single-family zones?
The full extent of the ripple effect of these bills will not be known for some time. If you are a property owner impacted by SB 9 or SB 10, it is important that you consult with a knowledgeable attorney to help you navigate through the implications of this legislation.
