Senate Bill 9
Senate Bill (SB 9)
On September 1, 2021, the California Legislature passed California Senate Bill 9 (SB 9) and it was signed into law by Governor Newsom on September 16, 2021, with the intent to increase residential densities within single-family neighborhoods across the State. SB 9 went into effect on January 1, 2022.
In late March, 2022, the California Department of Housing and Community Development published an "SB 9 Fact Sheet" available online here.
What Does SB9 Do?
SB 9 requires ministerial (staff-level) approval of certain housing development projects and lot splits on a single-family zoned parcel. The law allows for two new types of development activities that must be reviewed ministerially without any discretionary action or public input:
- "Two-Unit Housing Development" – Two homes on an eligible single-family residential parcel (whether the proposal adds up to two new housing units or adds one new unit to one existing unit).
- "Urban Lot Split" – A one-time subdivision of an existing single-family residential parcel into two parcels. This would allow up to four units (two units on each parcel).
In most circumstances, SB 9 will result in the potential creation of four dwelling units from an existing single-family parcel, generally in the four (simplified) scenarios depicted, below. In comparison, a single-family property is currently permitted three units, inclusive of a single-family dwelling, an Accessory Dwelling Unit (ADU), and a Junior ADU (JADU).
What Does SB9 Do?
The Town may adopt objective zoning, design, and subdivision standards, as well as procedural requirements in order to provide for orderly implementation of SB 9. Note that the Town may not impose any standard(s) that would physically preclude the construction of two units of less than 800 square feet each per property or hold any public hearings for units that meet the State rules (with limited exceptions). Additionally, the Town is also precluded from imposing side or rear setbacks greater than four feet or requiring on-site parking spaces for properties one-half mile walking distance of either a high-quality transit corridor or a major transit stop, or within one block of a car share vehicle.
What is the Town Doing?
On December 21, 2021, the Town Council adopted an Urgency Ordinance to implement SB 9 before the law went into effect on January 1, 2022. The Urgency Ordinance and associated staff report may be viewed at the links below.
On February 1, 2021, the Town Council adopted an extension of the Urgency Ordinance to implement SB 9. The extension of the Urgency Ordinance, including minor modifications, and associated staff report may be viewed at the links below.
