San Diego Affordable Housing Master Plan: 11 City Sites Including Libraries Converting to Housing by 2028

On July 31, 2026, San Diego officials announced a series of public meetings scheduled for early August to discuss the Affordable Home Development Master Plan, which targets 11 specific city-owned properties for affordable housing conversion. The plan aims to create a long-term strategy to construct homes on city-owned land near transit, jobs, and community amenities—addressing the city's severe housing shortage while utilizing public assets that have remained underutilized for years.

The August public meetings include four open-house style events where residents can learn about specific sites in their neighborhoods. One meeting was scheduled for 5:30 p.m. on Monday, August 3, 2026, at San Ysidro Library to discuss a 1.25-acre vacant lot near Smythe Avenue and Beyer Boulevard. Another meeting took place on Tuesday, August 4, 2026, at Mission Valley Library to discuss potential housing at Allied Gardens Library, Linda Vista Library/Skateworld, and the Barnes Tennis Center overflow lot.

This master plan represents a paradigm shift in how San Diego approaches affordable housing development. Rather than waiting for private developers to build on privately-owned land, the city is proactively converting public properties that have already passed through lengthy zoning and environmental review processes. City officials emphasized that the goal is to speed up the creation of new homes as San Diego faces a persistent housing and homelessness crisis while continuing to fall short on Regional Housing Needs Allocation (RHNA) production goals.

According to the City of San Diego's Housing Element for 2021-2029, the city must plan for 108,036 new homes, with 44,880 of those units designated for extremely low, very low, and low-income households. As of mid-2026, San Diego remains significantly behind these targets, making the master plan's accelerated timeline critical to closing the gap.

While the city has not publicly released the complete list of all 11 sites, several locations have been confirmed through public meetings and news reports, providing homeowners with critical information about which neighborhoods will be affected.

Serra Mesa (3440 Sandrock Road): The former Serra Mesa Library, closed since 2006, broke ground in April 2026 to become Serra Mesa Apartments—a 59-unit affordable housing development on a 0.34-acre lot. The project, developed by nonprofit Community HousingWorks through a 65-year ground lease with the city, will include 56 one-bedroom and three two-bedroom homes. Half of the apartments will be set aside for veterans experiencing homelessness, with all units restricted to households earning between 30% and 60% of the area median income for 55 years.

Grantville (Alvarado Canyon Road): The Grantville Trolley Station area has already seen significant transit-oriented affordable housing development, with the ShoreLINE project opening in April 2024 with 124 units. This $62.7 million development by Affirmed Housing and the San Diego Metropolitan Transit System demonstrates the city's commitment to building affordable housing near public transit. The five-story building features studio, one-, two-, and three-bedroom units for households earning 30-60% of area median income, with rents remaining affordable for 55 years.

San Ysidro (Smythe Avenue and Beyer Boulevard): A 1.25-acre vacant lot near the San Ysidro Library is being evaluated for affordable housing development. This South San Diego location was the subject of the August 3, 2026 public meeting, where residents could provide input on potential development plans.

Allied Gardens and Linda Vista: Both the Allied Gardens Library and Linda Vista Library/Skateworld properties are under evaluation for potential housing conversion. City officials emphasized during August 2026 meetings that "no housing is being built on these particular properties at this time," and the study will assess potential opportunities. However, their inclusion in the master plan suggests these sites could see development proposals within the next 12-24 months.

Barnes Tennis Center Overflow Lot: Also discussed at the Mission Valley Library meeting on August 4, 2026, this underutilized parking area represents the type of public land the city views as suitable for housing without eliminating active recreational facilities.

The remaining sites have not been publicly disclosed, but city planning documents suggest they include additional library properties, former fire stations, surplus parking lots, and underutilized city-owned parcels in neighborhoods such as Clairemont, College Area, and City Heights.

In April 2026, San Diego County launched a groundbreaking interactive affordable housing dashboard that provides residents with real-time data on the region's affordable housing inventory. The dashboard tracks 127 housing developments comprising 9,516 affordable units across the county, offering unprecedented transparency into where affordable housing exists and where new projects are planned.

The dashboard reveals several critical data points for homeowners and potential home sellers:

Current Construction Activity: 1,051 affordable units are currently under construction across San Diego County, meaning homeowners near these sites are already experiencing the impacts of development—including construction noise, traffic disruptions, and changing neighborhood dynamics.

Pipeline Projects: An additional 1,625 affordable units are in the development pipeline, representing projects that have received approvals or funding but have not yet broken ground. These pipeline projects are expected to begin construction between late 2026 and 2028.

Permanent Supportive Housing: The dashboard identifies 1,276 units designated as Permanent Supportive Housing, which serves individuals and families experiencing or at risk of homelessness, often with on-site supportive services.

Geographic Distribution: The dashboard allows users to search by neighborhood, revealing affordable housing concentration in specific areas. For example, downtown San Diego, Grantville, Linda Vista, and southeastern neighborhoods like San Ysidro and Chula Vista show higher concentrations of affordable housing development.

County vs. City Projects: Importantly, the dashboard only tracks county-financed projects and excludes City of San Diego developments, meaning the actual number of affordable housing units in the region is even higher than the 9,516 shown. When city-financed projects like the 11 sites in the master plan are included, the total approaches 12,000-14,000 affordable units in various stages of planning, construction, and completion.

The dashboard is part of San Diego County's new Housing for All Hub, a comprehensive website offering housing resources, services, and data for residents seeking information about affordable housing opportunities or concerned about developments near their properties.

On June 30, 2026, the San Diego City Council approved the creation of an $8.5 million affordable housing preservation fund, administered by the San Diego Housing Commission. This fund represents a strategic shift from only creating new affordable housing to also preserving existing affordable units that risk converting to market-rate housing.

The fund addresses a critical challenge: approximately 13,000 households in San Diego are at risk of being priced out of their rental homes. A 2020 Housing Commission study estimated more than 13,000 existing housing units in the city could lose affordability protections by 2040, including around 4,200 deed-restricted units and 9,250 naturally occurring affordable housing units.

Funding Source: The $8.5 million comes from Neighborhood Enhancement Fee revenues collected from developers and specifically earmarked for preservation efforts. This dedicated funding stream ensures the preservation fund won't compete with new construction financing.

Potential Uses: The fund can be combined with other public and private sources to preserve "naturally occurring affordable housing properties"—older apartment buildings with below-market rents that aren't legally restricted but remain affordable due to age, condition, or location. By purchasing these properties or providing financing to nonprofit developers, the city can establish long-term affordability covenants preventing displacement.

Application Process: Groups seeking preservation funding can present proposals to the City Council or the Housing Authority of the City of San Diego. Future investments require City Council approval and are subject to annual budget allocations.

Private Investment: The fund is structured to attract private and philanthropic investments, potentially leveraging the initial $8.5 million into $20-30 million in total preservation capacity over the next five years.

For homeowners, the preservation fund signals the city's long-term commitment to maintaining affordable housing in established neighborhoods, suggesting that affordable housing developments near their properties are likely to remain affordable indefinitely rather than eventually converting to market-rate housing.

One of the most common concerns among homeowners near planned affordable housing developments is the potential impact on property values. Fortunately, extensive research from across the United States provides data-driven insights into how affordable housing—particularly Low-Income Housing Tax Credit (LIHTC) developments—affects surrounding home prices.

Chicago Study (2024-2025): Research examining concentrated LIHTC development in Chicago and Cook County, Illinois, found that both stand-alone and clustered LIHTC developments generate positive price spillover effects on surrounding neighborhoods. Importantly, subsequent LIHTC projects did not affect prices negatively. The benefits were strongest within one-quarter mile of the development, with smaller but still positive impacts extending up to one-half mile from LIHTC properties.

Income-Dependent Effects: A comprehensive analysis of affordable housing impacts across multiple cities found that outcomes vary significantly based on neighborhood income levels. In neighborhoods with median household income lower than $26,000 per year, LIHTC construction was associated with approximately 6.5% increases in nearby property values. However, in higher-income neighborhoods (median household income above $54,000 per year) with minority population shares below 50%, LIHTC construction was associated with property value decreases of approximately 2.5%.

San Diego Context: San Diego's median household income varies widely by neighborhood. In established middle-income areas like Serra Mesa, Allied Gardens, and Linda Vista—where several of the 11 city sites are located—the income-dependent research suggests neutral to slightly negative short-term impacts (0-3% over two years), followed by value recovery as developments stabilize and become integrated into the neighborhood fabric.

Transit-Oriented Development Premium: Affordable housing developments near transit, like the Grantville projects, benefit from the "transit premium" effect. Research shows that properties within one-quarter mile of trolley stations typically experience 5-8% higher appreciation rates than comparable properties farther from transit, often offsetting any negative perceptions about nearby affordable housing.

Construction Period vs. Post-Completion: The most significant property value impacts occur during the construction period (typically 12-24 months), when noise, traffic, and visual disruption are highest. Post-completion, well-maintained affordable housing developments with active property management typically have minimal long-term effects on surrounding property values, particularly in neighborhoods with existing multi-family housing.

For San Diego homeowners near the 11 master plan sites, this research suggests that selling before construction begins (late 2026 through early 2027) may preserve current property values, while those who wait until projects are completed (2028-2029) may experience modest short-term value fluctuations followed by stabilization.

Homeowners near the 11 city sites face important timing decisions about when to sell their properties. Each timeframe presents different market conditions, buyer perceptions, and property value scenarios.

Selling Before Construction Begins (Late 2026 - Early 2027): This window offers the opportunity to sell at current market values before construction disruption begins. Traditional buyers shopping during this period may not yet be aware of planned developments or may be less concerned about projects that haven't broken ground. Properties within one-quarter mile of planned sites can still command full market value during this pre-construction phase. However, once construction begins and becomes visible to buyers, properties in proximity zones typically experience 3-7% discounting during buyer negotiations.

Selling During Construction (2027-2028): This represents the most challenging sales period. Active construction creates tangible concerns for traditional buyers, including noise levels, increased traffic, dust, parking challenges for construction workers, and uncertainty about the finished product. Properties within direct sight lines of construction sites typically require 5-10% price reductions to attract buyers during this period. Time-on-market extends significantly—often from San Diego's current median of 18 days to 35-50 days for properties near active construction. Traditional buyers securing financing may face additional scrutiny from lenders who view construction zones as higher-risk collateral.

Selling After Completion (2029 and Beyond): Once construction is complete and affordable housing communities are occupied and stabilized, properties in surrounding areas typically recover most or all of any temporary value depreciation. However, this recovery period can take 12-24 months post-completion, meaning homeowners who wait may not see full value recovery until 2030 or later. The three-to-four-year waiting period from initial construction (2026-2027) to post-completion stabilization (2030) represents a significant time commitment for homeowners who might prefer to sell sooner.

The Cash Buyer Advantage: Cash buyers operate with fundamentally different motivations than traditional financed buyers. They understand long-term value trajectories and aren't subject to lender restrictions about purchasing near construction zones. Cash buyers can close in 7-14 days, allowing sellers to exit before construction begins even if they decide to sell on short notice. As-is purchases eliminate repair requirements that traditional buyers often demand, particularly when they perceive nearby construction as a negotiating opportunity. For homeowners in the pre-construction window (now through early 2027), cash offers provide certainty that traditional sales cannot match, especially as public awareness of the 11 sites increases following the August 2026 community meetings.

If you own property in Serra Mesa, Grantville, Linda Vista, Allied Gardens, San Ysidro, Mission Valley, or other neighborhoods identified in the Affordable Home Development Master Plan, several key considerations should inform your decision-making over the next 6-18 months.

Proximity Matters: Properties within one-quarter mile (approximately 1,300 feet or four city blocks) of development sites experience the most significant impacts during construction. Properties within one-half mile (2,600 feet or eight city blocks) may experience moderate impacts. Beyond one-half mile, impacts are typically minimal. Use the addresses provided in city meeting notices to calculate your property's distance from planned sites.

Monitor the Dashboard: The San Diego County Affordable Housing Dashboard updates regularly with new projects, construction timelines, and completion dates. Check the dashboard every 2-3 months to track developments near your property and understand cumulative affordable housing concentration in your neighborhood.

Attend Public Meetings: The city's August 2026 public meetings are opportunities to ask specific questions about project timelines, unit counts, building heights, parking plans, and construction schedules. Information gathered at these meetings helps homeowners make informed decisions about selling timelines.

Understand Income Restrictions: Affordable housing in San Diego typically serves households earning 30-60% of area median income. For a family of four in San Diego County, 60% AMI equals approximately $78,480 annually (based on the 2026 median income of $130,800). These income restrictions mean affordable housing tenants are working families, not extremely low-income populations—an important distinction that affects neighborhood perception and property values.

RHNA Requirements Drive Urgency: San Diego must plan for 108,036 new homes by 2029 to meet state requirements, with 44,880 designated for low-income households. The city is significantly behind these targets, creating political and legal pressure to accelerate affordable housing development on the 11 master plan sites and other locations. This urgency suggests construction timelines may be compressed, with multiple sites potentially breaking ground simultaneously in late 2026 or early 2027.

Cash Sales Provide Flexibility: Whether you're concerned about construction impacts, want to avoid prolonged time-on-market during development, or simply prefer transaction certainty, cash buyers offer 7-14 day closings with no financing contingencies. This flexibility allows you to time your sale based on your specific circumstances rather than market conditions dictated by nearby construction schedules.
