Pulling Back For The Wider View
The San Diego Product Market Fit Case Study is Unfolding
A decade ago, as a mission-driven real estate investor, developer, and housing advocate, the goal was singular: lower rents in San Diego. Not through subsidies alone, but through better product, smarter delivery, and persistent policy reform. Today, the data reveals a quiet transformation: new supply of smaller, attainable units is reshaping the landscape and delivering measurable impact.
The Surface Story
Market Headlines
San Diego is experiencing the first rent decline in 15+ years. Vacancy is climbing across downtown and in heavy supply submarkets. Average asking rents are softening.
Everyone calls it "oversupply." But oversupply of what, exactly? When we pull back and examine the composition of new inventory, a different story emerges, which rooted in intentional design, careful planning, and a decade of advocacy finally gaining traction in the market.
The Hidden Shift in Unit Mix
New supply isn't neutral. It skews decisively smaller: more studios and compact one-bedrooms, often under 500 square feet. These units lease at fundamentally lower price points, typically in the $1,800–$2,200 range for older vintage compared to new construction of luxury, larger unit sizes, more of a mix of one and two bedrooms and resort living.
This composition effect quietly pulls the citywide average downward. It's not a market distortion.
"It's emerging product-market fit responding to real renter needs and income constraints."

The Quiet Math Behind the Headlines
Studio Units
~$1,800–$2,100/month
Compact footprints under 450 sf, micros/SROs under 250-350 sf, coliving, student and senior housing serving single occupants
One-Bedroom
~$2,150–$2,600/month
Efficient layouts for individuals and couples, more compact for affordability under 600 sf and as low as 400-500 sf
Two-Bedroom+
$2,500-3,000 /month
Traditional family-sized inventory at premium pricing, more compact to 700-800 sf down from 800-1,000 sf unit sizes
Three-Bedroom+
$3,000+ /month
Large family 25% each 2 and 3BR, also solving for roommates, WFH (affordable by the room) and multigenerational living
More small units entering the mix naturally softens the weighted average. This isn't market failure, it's structural rebalancing toward attainability and more choices .
Choice vs. Necessity:
Where Pressure Concentrates
Luxury Class A Market
"By-Choice" Segment
  • Higher vacancy rates emerging
  • Deeper concessions to attract renters
  • 5–10% effective rent cuts at premium tier
  • Absorbing sharpest adjustment pressure
Older Workforce & Affordable Housing
"By-Necessity" Segment
  • Resilient occupancy holding steady
  • Moderate pricing remains competitive
  • Serving essential workers and families
  • Minimal downward pressure observed

A haircut at the high end drags the overall market average down 5–6%—precisely matching current citywide trends. The data tells a nuanced story of market segmentation, not collapse.
The Subtle Layers Often Missed
Micro-scale developments, adaptive hotel conversions, and co-living style configurations sit outside standard apartment aggregates. They add meaningful attainable supply at lower price points while compounding the small-unit compositional bias.
These projects often are unsubsidized and creatively financed and are expanding housing choice for working-class San Diegans without requiring public dollars. Their impact on market averages is real but frequently underreported in conventional tracking.
Where Product-Market Fit Becomes Visible
Three built or building examples demonstrate this shift in concrete terms. Each project is unsubsidized, naturally affordable, and small-unit focused. All target working-class renters earning 60–80% of area median income. All prove that less square footage can deliver more housing opportunity.

Case Study: 2911 Adams Avenue
Completed in July 2024, this 72 unit development brought meaningful density to the North Park and Normal Heights corridor. The project features a deliberate mix: studios starting at just 345 square feet, one-bedrooms 465 square feet, and three-bedrooms to accommodate diverse household types.
Rents begin around $1,930–$2,000 monthly and are affordable to working class earning under $70,000 incomes. Ground-floor retail anchored by Cold Stone activates the street and contributes to neighborhood vibrancy. Fully leased without subsidies, it demonstrates that attainable housing and thriving community character can coexist.
Case Study: 64 Forty
The transformation of a former Howard Johnson hotel site consisted of new construction of 324 units of attainable housing at meaningful, institutional scale. Completed Summer 2025 near San Diego State University, the project leverages adaptive reuse, modular construction efficiency, and private funding to deliver unsubsidized workforce housing. The amenity package, parking and micro mobility and health/wellness offerings raised the bar for modular and micro unit and student / coliving in San Diego.
Ninety percent of units are naturally affordable to households earning approximately 70% of area median income. Small-unit focus meets student, faculty, and working-class demand in a high-opportunity neighborhood.
