HOUSING ELEMENT IMPLEMENTATION OVERLAY ZONE (HEIOZ)
The City’s Housing Element Implementation Overlay Zone (HEIOZ), codified in Chapter 11.21 of the La Cañada Flintridge Municipal Code aims to offer housing opportunities for current and future residents in a way that aligns with its existing development patterns and character. It facilitates housing production on suitable vacant and non-vacant opportunity sites identified in the City’s 2021-2029 Housing Element Sites Inventory and establishes regulations for developing housing on these sites. On several of these sites, multi-family residential development was previously subject to discretionary review or was not accommodated by the underlying zone. However, under the HEIOZ, these sites can now benefit from a streamlined approval process for eligible housing projects. Eligible housing projects are outlined in detail below.
The HEIOZ addresses the following goals of Programs 4-6 from the 2021-2029 Housing Element:
- Program 4 (Downtown Village Specific Plan)
Goal: Enhance Foothill Boulevard with place-based strategies that create a community-oriented town center that includes a mixture of commercial, office, and residential uses.
- Program 5 (Religious Institution Housing Overlay Zone)
Goal: Encourage religious institutions to build housing on property owned by religious institutions (also known as congregational land) which would provide sites that otherwise would not be available for affordable housing.
- Program 6 (By-Right Approval for Projects with 20 Percent Affordable Units)
Goal: Require by-right approval for certain projects with 20% affordable units.
By creating an overlay zone that allows for and streamlines housing project approvals on opportunity sites, La Cañada Flintridge is furthering the opportunity to achieve the city’s housing goals and meet the RHNA for the 2021-2029 Housing Element Cycle.

SENATE BILL (SB) 4: HOUSING ON INSTITUTIONAL LAND
What is Senate Bill 4?
On October 11, 2023, Governor Gavin Newsom signed Senate Bill (SB) 4 into law, limiting cities and counties’ ability to regulate the development of new housing on property owned by religious and higher education institutions. The City of La Cañada Flintridge acknowledges that using church and other institutional land for affordable housing offers developers a valuable opportunity by reducing land costs, risks, and processing time for development applications. This strategy enables congregations to advance their missions of supporting lower-income populations while enhancing the financial stability of religious institutions.
Does my property qualify? And if so, what can I build?
If your property qualifies as a Religious Institution per Gov. Code Section 65913.16.b.10 or a Higher Education Institution per Edu. Code Section 66010.4, on or before January 1, 2024, your property may be eligible to build housing under Senate Bill (SB) 4. To verify eligibility, please review all site requirements described in Gov. Code Section 65913.16.
Per SB 4, housing projects on eligible properties that provide 100% affordable units – with up to 20% for moderate-income households and up to 5% for staff units – can achieve additional density of up to 40 du/acre and one additional story above the height otherwise permissible under the site’s zoning.
Please note that SB 4 projects are required to meet prevailing wage requirements and labor standards, as described in Gov. Code Section 65913.16.d-g.
How does this differ from the Housing Element Implementation Overlay Zone?
SB 4 allows eligible religious or other institutional land to apply for streamlined ministerial review, regardless of whether it is located within the HEIOZ, provided that the proposed project is for 100% affordable housing.
The HEIOZ provides another option for land owned and operated by a religious facility to apply for streamlined ministerial review, if the proposed project provides at least 15% of its units as affordable housing.
Please see below summary of applicability and incentives available:
| Density | Height Incentive | Affordability Requirements | |
|---|---|---|---|
| Public/Semi-Public Zone (within HEIOZ) | 25–30 du/ac | N/A | At least 15% of units are set aside for affordable housing (extremely low-income, very low-income, or moderate affordability). |
| Religious or Other Institutional Land – Eligible for Senate Bill 4 (not within HEIOZ) |
40 du/ac | One additional story | 100% of units are set aside for affordable housing (extremely low-income and very low-income) — with up to 20% for moderate-income households and up to 5% for staff units. |

RESIDENTIAL DEVELOPMENT IN COMMERCIAL ZONES
WHAT ARE ASSEMBLY BILL (AB) 2011, SENATE BILL (SB) 6, and ASSEMBLY BILL (AB) 2243?
In 2022, the California Legislature passed Assembly Bill 2011 (AB 2011), known as The Affordable Housing and High Road Jobs Act of 2022, and Senate Bill 6 (SB 6), known as the Middle Class Housing Act of 2022. These bills aimed to address California’s housing crisis by paving the way for residential development on sites currently zoned for commercial or retail uses. Both bills took effect on July 1, 2023.
In 2024, Assembly Bill 2243 (AB 2243) was passed, which significantly expanded the scope of SB 2011 and SB 6, to allow additional development opportunities for residential uses in commercial zones.
Please see the table below with the overall requirements, limitations, and standards. Please note, this is not an exhaustive list, and the state bills (linked above) should be referenced for all regulations:
CAN I APPLY FOR A PROJECT UNDER SB 6, AB 2011, or AB 2234?
Please complete the Mixed-Use/Multi-Family Ministerial Approval Application and submit via ConnectLCF. Upon submission, the city will conduct a thorough review of all eligibility criteria to confirm whether the proposed project qualifies under the applicable state provisions.
You can also apply for a project with another entitlement, such as a Density Bonus, while invoking SB 6, AB 2011, or AB 2234.
SENATE BILL (SB) 9: URBAN LOT SPLITS & TWO-UNIT DEVELOPMENTS
Senate Bill 9, also known as the Housing Opportunity and More Efficiency (HOME) Act, is a state law that aims to increase residential development potential by expanding infill development opportunities by making it easier to apply for a lot split or two-unit development in a single-family zone.
What types of projects are approved under SB 9?
There are two key components of the bill:
Urban Lot Splits: Allows for subdividing an existing single-family lot into two new individual parcels without meeting the minimum lot size required by the underlying zone. Urban Lot Splits are allowed if:
- No previous Urban Lot Split on the property
- No adjacent parcels were split by the same property owner
- Owner must reside at a unit on one of the Urban Lot Split’s newly created lots for at least three years from the date of map approval
Two-Unit Developments: Allows for the development of two primary dwelling units per single-family zoned lot. Two-Unit Developments are allowed if:
- No alteration or demolition of more than 25% of the exterior walls of the existing unit that has been occupied by a tenant in the last three years
- No alteration or demolition of a unit where an Ellis Act withdrawal has taken place in the last 15 years
What do different development scenarios look like?
These examples illustrate some of the most common development scenarios and do not represent every possible lot/unit configuration.

Can I utilize SB 9 on my property?
To utilize SB 9, a property must meet all of the following eligibility criteria:
- Must be in a single-family zone
- Cannot be a historic resource or located in a historic district
- Cannot be located within the boundaries of wetlands, hazardous waste sites, floodways, conservation areas, or habitat areas for certain species
- Short-term and vacation rentals are prohibited, as units may only be rented for 30 days or longer. However, Home-Sharing as an accessory use to a primary residence is permitted.
Many properties within the city are eligible to utilize Senate Bill 9. To confirm eligibility, a thorough review of the SB 9 application eligibility criteria checklist is recommended. Additionally, city planning staff will review the project for eligibility.
My property is within the Very High Fire Severity Zone (VHFSZ) and has limited access, can I apply for an SB 9 project?
Since all of La Cañada Flintridge is within the VHFSZ, all SB 9 projects within the city must comply with the criteria established in Government Code Section 65913.4
Any proposed urban dwelling located within any of the areas identified on Figure SE-6 Neighborhoods with Single Point of Access of the draft Safety Element (2021), at increased risk of wildfire, must demonstrate compliance with California Fire Code, Appendix D – Fire Apparatus Access Roads.
Additionally, if necessary, an access easement must be provided over the front parcel to the rear parcel for access to the public right-of-way, providing public services and facilities, maintenance of utilities, and (if required) emergency access. Each easement must be shown on the parcel map.
How do I apply for an SB 9 project?
Step 1: Complete the SB 9 Application and apply for SB 9 review on the Connect LCF portal.
The project will be thoroughly reviewed by City Staff for compliance with State Law and the City’s Municipal Code.
Proposals for urban lot splits will be reviewed ministerially, without discretionary review or a hearing, if they comply with all the requirements of the Zoning Code.
Step 2: Apply for Los Angeles County Fire review by submitting for a “Fire Land Development – Final Map – Parcel” review on EPIC-LA. A County fire reviewer will be assigned to the case, and a coordinated review of the property will be conducted. This review must be complete prior to the city approving the SB 9 application.
Step 3: Record any required documents, such as deed restrictions or easements. Including the covenant linked below, stating that the owner will occupy one of the housing units for a minimum of three years.
Step 4: Provide proof of all recorded covenants, and the city will approve the parcel map.
