Senate Bill (SB) 9 is a California State Law which took effect on January 1, 2022. SB 9 creates new opportunities for infill housing by requiring cities to ministerally approve projects meeting certain criteria.
There are several qualifying criteria for development under SB 9 in Tustin:
The City of Tustin’s SB 9 Ordinance defines development opportunities for both two-unit developments and urban lot splits. There are a variety of site plan layouts for both two-unit developments and urban lot splits, but in any given scenario there is a maximum of four units that can be developed.
The diagram on the left depicts a traditional rectangular shaped single-family parcel with what is known under SB 9 as a “Two-unit Development”. In this scenario, a property owner with a single-family home may construct a second home on the property and may also build an Accessory Dwelling Unit and Junior Accessory dwelling unit resulting in the development of a total of four dwelling units on a single-family parcel.
URBAN LOT SPLITS
The two diagrams on right depict scenarios that are under the “Urban Lot Split” category. In these two Urban Lot Split Scenarios, the property owner may subdivide a single-family parcel into two lots and in these scenarios ADUS or JADUS are not allowed in conjunction with Urban Lot Splits.
The middle diagram shows a traditional rectangular lot split down the middle, resulting in two lots. Each of these lots, can then be combined with the Two-unit Development concept, which may result in each lot having a total of two units.
The diagram on the far right, depicts a “flag style” urban lot split, where access to the new lot at the rear has access to the street and/or public right of way from a narrow strip of land, resulting in the rear lot resembling the shape of a flag. In the Urban Lot Split scenarios, each lot may accommodate up to two units.
Tustin’s SB 9 Ordinance applies to single family residentially zoned parcels. For Urban Lot Splits, the property must be owned by the applicant for a period of three years; and for Two-unit Developments, the units may not be used for short-term rentals.
Additional provisions include:
Development under SB 9 requires approval by the City of Tustin. Please call our Planning Division at (714) 573-3140 or email TustinPlanning@tustinca.org to ensure your project qualifies as an SB 9 development prior to submitting for Building Permits and/or a Parcel Map.
No, your property may not be a historic landmark or in a historically designated Historic District – In Tustin, these criteria result in the exclusion of single-family parcels located in the Old Town Area.

SB 9 does not currently override the Covenants, Conditions, and Restrictions (CC&Rs) commonly used by HOAs; therefore, HOAs currently maintain the authority to either allow or prohibit SB 9 developments within their respective boundaries.
No, since SB 9 developments are required by the State to be approved ministerially, there is no public notification or hearing required and City may not apply a requirement for discretionary action, such as a public hearing/notification, as a condition of approval.
