San Diego 10% Affordable Housing Mandate Upheld: $12.5M Impact

The Federal Court Ruling: What Happened and Why It Matters

In January 2026, Judge Sabraw issued his ruling in the case Palmer Kearney Mesa Properties, LP v. City of San Diego, rejecting arguments from G.H. Palmer Associates—a developer with a portfolio worth $4.5 billion controlling more than 11,600 apartments—that the city's inclusionary housing ordinance constituted an unconstitutional "taking" of private property.

"Developers can choose whether to build housing, and if they do, they must comply with the city's development rules," Sabraw wrote in his decision, according to the San Diego Union-Tribune.

The lawsuit challenged San Diego's requirement that new residential developments either:

• Set aside 10% of units for low-income households earning at or below 60% of Area Median Income (AMI) for a minimum of 55 years, or
• Pay an in-lieu fee of $25 per square foot into the city's affordable housing fund

With the appeal deadline expiring on February 26, 2026, the ruling is now legally final, ensuring the ordinance will continue shaping San Diego's housing landscape for years to come.

The Numbers Behind the Mandate: $12.5 Million and Counting

The financial impact of San Diego's inclusionary housing ordinance is substantial. In 2025 alone, the city committed approximately $12.5 million in fees collected from developers to affordable housing programs, funding rental housing, accessory dwelling units (ADUs), and housing for people experiencing or at risk of homelessness.

To understand the magnitude of these fees, consider a typical new apartment building:

This $25,000-per-unit fee gets passed directly to buyers through higher purchase prices or to renters through elevated monthly rates. For developers choosing to provide on-site affordable units instead, the economics become even more complex, as they must subsidize 10% of units at rates affordable to households earning 60% of AMI—currently $78,480 for a family of four, based on San Diego County's 2025 Area Median Income of $130,800.

A Brief History: From $1 to $25 Per Square Foot in San Diego

San Diego's inclusionary housing ordinance has evolved significantly since its inception, reflecting the city's ongoing struggle to address affordability challenges.

2002-2003: Initial Adoption

The City Council first approved the ordinance on August 6, 2002, with regulations taking effect in 2003. The initial in-lieu fee started at just $1 per square foot, and the law required developers to include affordable units or pay the modest fee.

Almost immediately, the Building Industry Association sued over the ordinance. As fees were scheduled to nearly triple by July 2006, the industry pushed for a compromise that preserved the program but changed when fees were assessed and froze increases for several years, according to the City of San Diego.

2003-2019: Gradual Increases

Over 16 years, the in-lieu fee gradually rose from $1 to $2.50 per square foot—a pace that failed to keep up with skyrocketing housing costs in San Diego.

2019: Major Overhaul

City Councilwoman Georgette Gomez first proposed substantial amendments in 2017, but lacked the council president's power to docket agenda items until her colleagues unanimously appointed her to the position in December 2018. On September 17, 2019, the council approved comprehensive amendments in a 5-4 vote, as reported by KPBS.

The 2019 amendments dramatically strengthened requirements:

• Developers must lease 10% of rental developments (10+ units) at or below 50% AMI, or 15% of units at or below 80% AMI
• For-sale developments must make 10% available at or below 100% AMI, or 15% at or below 120% AMI
• The in-lieu fee increased tenfold to $25 per square foot
• Requirements were phased in over five years beginning July 1, 2020

2023-2026: Constitutional Challenge and Vindication

The Palmer Kearney Mesa Properties lawsuit filed in 2023 represented the most serious legal challenge to the ordinance's constitutionality. Judge Sabraw's January 2026 dismissal and the expiration of the appeal deadline on February 26, 2026, have now settled the matter definitively in the city's favor.

How the Mandate Impacts New Construction Costs

The inclusionary housing requirement arrives at a time when San Diego construction costs are already among the highest in the nation. The compounding effect creates significant challenges for new development and widens the pricing gap with existing inventory.

Labor Shortage Drives Costs Up 6-8% Annually

San Diego's construction industry faces a severe labor crisis. According to Pacific Beach Builder, skilled trade wages are increasing 6-8% annually due to workforce shortages. Labor comprises roughly 35-39% of total construction costs locally, and the industry needs to attract 349,000 new workers nationally in 2026 just to meet current demand.

The CEO of the Associated Builders and Contractors of San Diego noted that "most of the time the issue the local industry faces is not a lack of jobs, but a lack of workers," as reported by K2 Staffing.

Project schedules now require a 10-15% labor float to account for potential delays caused by the shortage, further increasing costs and extending timelines.

Coastal Premium: 20-30% Above National Averages

Even before inclusionary fees are applied, San Diego construction costs run 20-30% higher than national averages. Custom home construction ranges from $250 to $400 per square foot, with coastal properties commanding the upper end of that range, according to Simply Buildable.

Total Cost Comparison: New vs. Existing

Consider the total cost picture for a buyer choosing between new construction and an existing home:

Geographic Impact: Which San Diego Neighborhoods Are Affected?

The inclusionary housing ordinance applies citywide but impacts different neighborhoods in varying ways based on development activity and existing housing stock.

High-Impact Development Areas

Kearny Mesa: As the site of the Palmer lawsuit's 1,642-unit proposed project, Kearny Mesa represents a focal point for larger-scale developments subject to the 10% requirement. The ordinance applies to projects with 10 or more units in non-coastal areas, affecting development from the I-15 corridor through Linda Vista and into Serra Mesa.

Pacific Beach: A new 59-unit affordable housing development called Rose Creek Village broke ground in 2025, featuring studio apartments for residents earning up to 60% AMI (currently $69,480 for a single-person household), with 18 units specifically for veterans experiencing homelessness, according to San Diego County News Center. The project demonstrates how the ordinance funds housing in high-resource areas with strong access to jobs, schools, and transportation.

Downtown San Diego: With median home prices at $725,000, downtown neighborhoods including Little Italy, East Village, and Marina District are seeing continued development pressure. The inclusionary requirement affects all new projects, though the lower existing home prices compared to coastal areas create different market dynamics. The impact extends through Banker's Hill and into the 92103 zip code area.

Established Neighborhoods with Limited New Development

La Jolla: With a median home price exceeding $3 million and median rent at $8,000 per month, La Jolla has limited development activity. The ordinance has minimal impact here because most housing stock is existing inventory not subject to inclusionary requirements.

North Park and Surrounding Mid-City Neighborhoods: Median prices in North Park reached $1,000,000 in January 2026, up 12.2% year-over-year, with homes selling after 33 days on market, according to Redfin. As an established urban neighborhood, most transactions involve existing homes exempt from the ordinance. Adjacent communities including University Heights, Normal Heights, and Hillcrest share similar characteristics, with the 92104 and 92116 zip codes showing strong existing home values.

South Park and Eastern Neighborhoods: With median prices at $1,311,000 as of February 2026, South Park's primarily single-family character limits new multi-unit development subject to inclusionary requirements. Nearby areas like Golden Hill, Rolando, College Area, Allied Gardens, Del Cerro, and San Carlos similarly see most real estate activity in the existing home market rather than new construction.

Point Loma, Ocean Beach, Mission Beach: These coastal neighborhoods face the more stringent threshold of projects with 5 or more units, but limited available land means most transactions involve existing homes.

Clairemont, Bay Park, and Central San Diego: These established communities along the I-5 corridor have mature housing stock with limited large-scale development. Properties in the 92117 zip code area primarily involve existing home sales where inclusionary fees don't apply.

The Cash Buyer Advantage in the Existing Home Market

The widening price gap between new construction (burdened with inclusionary fees and elevated labor costs) and existing inventory creates a unique opportunity for cash buyers targeting existing homes.

Why Sellers Prefer Cash Offers on Existing Homes

How Existing Homes Avoid Inclusionary Costs

Homes built before the inclusionary ordinance took effect in 2003—or any home built before the 2019 amendments significantly increased requirements—carry no embedded affordable housing fees. This creates a cost-per-square-foot advantage:

For cash buyers focused on existing inventory, the absence of inclusionary fees translates to better value and stronger negotiating position with sellers who appreciate speed and certainty.

Current San Diego Market Conditions: Opportunity for Strategic Buyers

Several converging market factors in early 2026 create ideal conditions for cash buyers targeting existing homes:

Inventory at Multi-Year Highs

By 2026, housing inventory reached its highest levels since the 2020 recession, reflecting slowing demand and reduced sales, according to Compass San Diego. The market showed 1.7 months supply for single-family homes and 2.5 months supply for condos/townhomes as of January 15, 2026.

Higher inventory gives buyers more negotiating leverage and more time to conduct due diligence without intense competition.

Extended Days on Market

Homes in San Diego now sell after 34 days on market in February 2026, compared to 27 days in February 2025, according to Redfin. This 26% increase in marketing time signals that sellers are becoming more receptive to strong offers that provide certainty.

Price Trends Across San Diego Neighborhoods: From Coastal to Inland

While some neighborhoods like North Park saw 12.2% appreciation, overall San Diego median prices fell 5.7% year-over-year in February 2026. This creates pockets of opportunity where sellers have adjusted expectations and are motivated to close quickly. Coastal areas like La Jolla and Pacific Beach maintain premium pricing, while mid-city neighborhoods including City Heights, El Cerrito, and the College Area offer more affordable entry points for cash investors targeting the existing home market.

Locked-In Homeowners Creating Opportunity

Many San Diego homeowners secured mortgage rates below 4% in 2020-2021 and are hesitant to move. When they do decide to sell—due to job relocation, family changes, or downsizing—they often prioritize speed and certainty over squeezing every dollar from the sale. Cash buyers positioned to close in 7-14 days offer exactly what these sellers need.

What San Diego's $12.5 Million in Fees Actually Funds

Understanding where inclusionary housing fees go provides context for the program's impact:

Projects like the Rose Creek Village in Pacific Beach—with 59 units for low-income residents and veterans—demonstrate how these fees translate into tangible housing opportunities in high-resource areas.

Legal Precedent: What the San Diego Sabraw Ruling Means for Other California Cities

Judge Sabraw's dismissal of the constitutional challenge reinforces the legal foundation for inclusionary housing programs throughout California and potentially nationwide.

The ruling affirmed that:

1. No Unconstitutional Taking: Requiring developers to provide affordable housing or pay fees does not constitute a "taking" of private property because developers choose whether to build
2. Local Authority: Cities have broad authority to regulate land use and development standards within their jurisdictions
3. Public Benefit: Addressing housing affordability through development regulations serves a legitimate public purpose

With the February 26, 2026 appeal deadline expired, this precedent stands as persuasive authority for other municipalities considering or defending similar ordinances.

Conclusion: Navigating San Diego's Post-Ruling Housing Market

The federal court's validation of San Diego's 10% affordable housing mandate represents a watershed moment for the city's housing policy. With $12.5 million in developer fees collected in 2025 and the legal foundation now secure, the inclusionary ordinance will continue shaping development for the foreseeable future.

For existing homeowners, this creates a unique market position. Your property carries no embedded inclusionary fees, offers immediate occupancy, and can close quickly with the right buyer. In a market where new construction faces $25-per-square-foot fees on top of already elevated labor costs and coastal premiums, existing homes offer compelling value.

Cash buyers recognize this dynamic and position themselves to move quickly when motivated sellers emerge throughout San Diego County neighborhoods. Whether you're downsizing in University Heights, relocating from Bay Park for work, dealing with inherited property in Allied Gardens or Del Cerro, or simply want to avoid the uncertainty of traditional sales with financing contingencies and repair negotiations, the 7-14 day closing timeline cash buyers offer provides certainty in an uncertain market.

The inclusionary housing ordinance serves important public policy goals, funding thousands of affordable units across San Diego from Mission Valley to San Carlos. But for individual homeowners ready to sell, understanding how this mandate affects the broader market helps you make informed decisions about timing, pricing, and buyer selection.

If you own an existing home in San Diego—whether in the 92116, 92104, 92103, or 92109 zip codes, or anywhere throughout the county—and want to capitalize on the pricing advantage versus new construction burdened with affordable housing fees, now represents an ideal time to explore your options. The convergence of legal certainty around the inclusionary ordinance, elevated construction costs, inventory at multi-year highs, and extended days on market creates favorable conditions for sellers who value speed and certainty.
