Building a Roadmap for San Diego: Inside the Housing Blueprint Strategy
San Diego County is facing a historic housing affordability crisis, forcing many residents to spend over half their income just to keep a roof over their heads. To tackle this head-on, the County is developing a comprehensive Housing Blueprint to align policies, funding, and development goals through 2029.
Core Question: How can the San Diego Housing Blueprint unify regional efforts to maximize affordable housing production and protect vulnerable populations?
Highlights
- A strategic framework built on the “5 Ps”: Produce, Promote, Preserve, Prevent, and Protect.
- Direct oversight focused on the 500,000 residents living in the County’s unincorporated areas.
- Creation of a specialized task force to address financing for middle-income “missing middle” housing.
- A multi-phase timeline targeting final Board of Supervisors approval by Summer 2024.

Defining the Scope of County Housing Authority
Regional Impact vs. Unincorporated Focus
The County of San Diego operates under a unique dual mandate when it comes to housing. While it manages social services and approximately 10,000 Section 8 vouchers across the entire region, its land-use and zoning authority is strictly limited to the unincorporated areas.
This distinction is vital for residents to understand because it determines who has the final say on new developments. While the 18 incorporated cities like Oceanside or Chula Vista manage their own municipal approvals, the County governs the rural and semi-rural zones where roughly 500,000 people currently reside in 175,000 homes. The Blueprint seeks to maximize the impact of the County’s specific powers in these areas while coordinating with city partners on broader regional funding and homelessness initiatives.

Q: Does the County control housing projects within the City of San Diego?
A: No, projects within the 18 incorporated cities must be approved by their respective city councils, though the County may provide regional funding for specific affordable projects.
Q: How many people live in the zones directly impacted by County land-use policies?
A: Approximately 500,000 people living in 175,000 housing units across the unincorporated rural and suburban areas.
The Strategic Pillars: The “5 Ps” of Housing
A Framework for Sustainable Growth
The Housing Blueprint isn’t just a list of construction targets; it is a values-driven document centered on five core pillars adopted from the San Diego Association of Governments (SANDAG). These pillars—Produce, Promote, Preserve, Prevent, and Protect—ensure that the response to the housing crisis is equitable and sustainable rather than just high-volume.
The “Produce” pillar focuses on building homes for all income levels, but the “Promote” and “Preserve” pillars are equally critical. They mandate that new housing must be inclusive and environmentally sustainable, aiming to reduce greenhouse gas emissions by placing homes near transit or amenities. Meanwhile, the “Protect” and “Prevent” pillars focus on the human side of the crisis: stopping the displacement of long-term residents and ensuring that tenants have the legal and social support needed to stay in their homes.

Q: How does the Blueprint address environmental concerns?
A: One of the eight specific objectives is to analyze location factors to reduce greenhouse gas emissions and ensure sustainability in all new developments.
Q: Is this a brand-new effort by the County?
A: While the County has launched over 20 housing initiatives since 2019, this Blueprint is a new tool designed to unify those disparate programs into a single, maximized strategy.
Financing the “Missing Middle” and Future Implementation
Bridging the Funding Gap
One of the most persistent hurdles in San Diego is the lack of housing for middle-income families—those who earn too much for traditional subsidies but not enough to afford market-rate homes. The County is currently forming a specialized Housing Finance Task Force to investigate new tools and partnerships specifically for this demographic.
This task force, launching in early 2024, will bring together financial stakeholders to look at acquisition strategies and flexible funding models. The goal is to move beyond the rigid constraints of existing state and federal programs to create local solutions that work for teachers, nurses, and other essential workers who are currently priced out of the region.

💡 Digging Deeper
Q: Are there plans for “Tiny Homes” on wheels in the unincorporated areas?
A: Currently, there are no immediate plans or specific updates regarding the authorization of tiny homes on wheels within the County’s upcoming schedule.
Q: How does the Blueprint interact with the Regional Housing Needs Allocation (RHNA)?
A: While the Blueprint is informed by state obligations like RHNA, it is a strategic document that balances those mandates with local priorities and feasibility.
Key Takeaways
The San Diego County Housing Blueprint represents a shift from reactive policy-making to a proactive, long-term strategic vision. By focusing on the “5 Ps,” the County is attempting to address not just the quantity of housing, but the quality of life for residents, ensuring that growth does not come at the cost of displacement or environmental degradation.
Success will depend heavily on the work of the upcoming Finance Task Force and the ability of the County to coordinate with the 18 independent cities within its borders. As the process moves toward final approval in Summer 2024, the emphasis remains on transparency, community feedback, and creating a “fact-based” plan that actually leads to shovels in the ground.
