Unlocking California’s housing future: How SB 79 redefines affordability and connected communities

California’s housing crisis is no longer just a headline; it is a structural challenge that defines the daily lives of millions. As the state grapples with a deficit of millions of homes, the legislative response has shifted from incremental changes to bold, systemic reforms. The latest, and perhaps most significant, tool in this arsenal is Senate Bill 79 (SB 79).

Introduced to streamline the creation of affordable housing and foster "connected communities," SB 79 represents a pivotal shift in how California approaches land use, density, and urban integration. For developers, city planners, and investors, the bill is a beacon of opportunity. However, navigating the complexities of this new regulatory landscape requires more than just intent; it requires high-fidelity data.

At Cotality, we believe that the path to a more affordable California is paved with intelligence. By unifying parcel-level data with the specific mandates of SB 79, we empower stakeholders to move from policy awareness to project execution.

Understanding SB 79

SB 79 is designed to lower the barriers that have historically stalled affordable housing projects. At its core, the bill targets the missing middle and lower-income brackets by incentivizing development near transit hubs and within existing urban footprints.

Key pillars of SB 79 include:

1. Streamlined approvals: Standardizing the approval standards or projects that meet specific affordability and density criteria.

2. Connected communities: Prioritizing developments that link residential zones with essential services, transit, and employment centers.

3. Density bonuses and zoning flex: Allowing for increased floor-area ratios and height limits when developers commit to higher percentages of affordable units.

While the intent is clear, the execution is complex. Identifying which specific parcels qualify for SB 79 incentives requires a deep dive into zoning overlays, transit proximity, and historical land use. This is where the gap between policy and property begins, and where Cotality steps in.

Why data is the foundation of SB 79 success

Success under SB 79 requires bridging the gap between legislative intent and site-specific reality. While developers search for high-yield parcels with minimal regulatory friction, city planners must determine where increased density will strengthen a community’s infrastructure.  

Most organizations currently struggle with analysis paralysis due to fragmented datasets, relying on static PDF maps and manual transit calculations, which can lead to costly oversights and missed opportunities. Cotality solves this by providing a unified intelligence layer, bringing SB 79 criteria directly into the property search and evaluation workflow to ensure every decision is grounded in real-time data.

By leveraging CLIP, Cotality enables precision site selection where project viability can hinge on just a few hundred feet of transit proximity or specific zoning overrides. This granular data, paired with Cotality Growth Intelligence, allows investors to move beyond isolated builds and identify connected communities on a clear upward trajectory. By analyzing the surrounding development lifecycle, stakeholders can ensure that new affordable housing is not built in a vacuum, but is instead integrated into a vibrant, sustainable ecosystem primed for long-term success.

Maximizing home affordability

The financial math of affordable housing is famously difficult. SB 79 changes that math by offering density as a form of currency. If an investor can build 20% more units on a site, the project becomes viable. Additionally, Cotality gives the investors insight into:

• Risk mitigation: By using loan-level market analytics (LLMA), investors can see the mortgage performance and financial health of specific neighborhoods. This data is vital for securing the private equity or low-income housing tax credits (LIHTC) needed to fund SB 79 projects.

• Automated feasibility: Instead of hiring consultants for weeks of work, Cotality users can filter for parcels that meet SB 79 criteria across an entire county in seconds.

• Impact reporting: For ESG-conscious investors, Cotality provides the "evidence-ready" data needed to prove that a project is delivering on its social promises of creating jobs, providing housing, and reducing commute times through connectivity.

Empowering state and local governments  

For local governments, SB 79 can feel like a loss of local control. However, when viewed through the lens of data, it is an opportunity to modernize urban planning by:

• Identifying high-priority sub-zones: Municipalities can use Cotality to map out which areas are best suited for SB 79 density increases. By prioritizing parcels with existing infrastructure capacity, cities can guide growth in a way that is fiscally responsible.

• Transparency and public trust: By integrating Cotality data and analytics, cities can show residents exactly why certain areas are being developed. When you can point to data showing that a new SB 79 project will reduce local traffic by increasing transit use, you build community buy-in.

• Compliance and oversight: SB 79 comes with reporting requirements. Cotality’s platform automates the tracking of new units, affordability levels, and proximity to services, making state-level reporting seamless and auditable.

The vision  

SB 79 isn't just a housing bill; it's a connected communities bill. A community is connected when a resident can walk to a grocery store, take a bus to work, and afford their rent in the same neighborhood.

Data is the invisible thread that ties these elements. By layering real estate metrics with transit data and economic indicators, Cotality allows stakeholders to see the social fabric of a neighborhood. We can help you identify opportunity deserts where an SB 79 project would have the highest community uplift, and growth engines where housing will fuel local business expansion.

Turning legislation into legacy

California stands at a crossroads, but legislation alone won't solve the housing crisis; that requires the right tools to turn policy into a legacy. Cotality provides the parcel-level intelligence necessary to navigate SB 79, ensuring every investment helps build an affordable and connected future.
