101 Ash Street: San Diego's 252-Unit Affordable Housing Conversion

The 21-story high-rise, which first opened in 1968 and has sat vacant for over six years due to asbestos contamination, represents San Diego's attempt to redeem what became known as the city's worst real estate deal. Developer Kelly Moden's MRK Partners and cREate Development secured a 65-year ground lease with financing from the San Diego Foundation and U.S. Department of Housing and Urban Development (HUD) to convert the building into 100% affordable housing.

The amended deal increases the interest rate from 4% simple to 5% compound interest, extends the ground lease from 60 to 65 years, and adds two additional units to the original 250-unit proposal. Construction is expected to begin in May 2026, with completion targeted for May 2028.

While Pacific Beach Builder primarily serves coastal communities including Pacific Beach, La Jolla, Mission Beach, Bird Rock, and Tourmaline Surfing Park, the 101 Ash Street project offers valuable lessons about adaptive reuse financing and complex environmental remediation that apply to potential conversion projects throughout San Diego's coastal neighborhoods. The downtown location provides insight into challenges distinct from the Coastal Commission requirements and ocean proximity issues typical of projects near Crystal Pier or the Mission Beach boardwalk.

What is the 101 Ash Street affordable housing conversion project?

The 101 Ash Street conversion is a mixed-use adaptive reuse project that will transform a vacant 21-story office building into 252 affordable housing units with ground-floor retail and childcare facilities. The project by MRK Partners and cREate Development includes 249 income-restricted units (69 studios, 55 one-bedroom, 73 two-bedroom, and 55 three-bedroom apartments) plus 3 unrestricted manager's units.

The building will also feature 138 parking spaces (a 0.55 parking ratio per unit, which is significantly lower than coastal San Diego requirements in Pacific Beach, La Jolla, and Mission Beach), 25,000 square feet of retail space, and a 4,000-square-foot childcare center. All income-restricted units will serve families earning between 30% and 80% of the Area Median Income (AMI), with rents capped at 30% of household income.

The project received a $63.8 million allocation of tax-exempt bonds from the California Debt Limit Allocation Committee and is entitled to $82.2 million in tax credit equity, equivalent to $9.6 million in federal low-income housing tax credits distributed annually to project investors at 86 cents on the dollar for 10 years.

Why did the City Council approve this deal amendment in September 2026?

The September 15, 2026 amendments were required by the developer's lenders—the San Diego Foundation and HUD—and are actually favorable to the city. The changes include extending the ground lease from 60 to 65 years, increasing the unit count from 250 to 252, and raising the interest rate the developer pays the city from 4% simple interest to 5% compound interest.

These modifications address a roughly $8 million financing gap caused by tax credit policy changes that delayed the original deal closure. The developer will pay $45.6 million to the city over the 65-year lease term, with the first payment not due for 15 years.

City staffers indicated the amendments provide better financial terms for San Diego while meeting lender requirements necessary to close the deal and begin construction. The City Council's approval signals the project's move from political controversy to practical implementation, offering builders in Pacific Beach, La Jolla, Mission Beach, and Bird Rock insight into how politically sensitive projects can be restructured to satisfy multiple stakeholders.

What are the income requirements for these affordable housing units?

The 249 income-restricted units at 101 Ash Street (now officially addressed as 107 Ash Street) will serve households earning between 30% and 80% of the San Diego County Area Median Income. While the search results don't provide the exact breakdown by AMI tier, all units will have rents capped at 30% of the household's income.

For context, San Diego County's 2026 AMI for a family of four is approximately $108,000. This means:

• 30% AMI: Households earning approximately $32,400 annually
• 50% AMI: Households earning approximately $54,000 annually
• 60% AMI: Households earning approximately $64,800 annually
• 80% AMI: Households earning approximately $86,400 annually

The mix of studio, one-bedroom, two-bedroom, and three-bedroom units across these AMI tiers creates a diverse affordable housing community serving extremely low-income to moderate-income San Diego families. The 30% income cap on rents ensures housing costs remain affordable even as incomes fluctuate.

What construction challenges does this San Diego downtown conversion face that differ from Pacific Beach projects?

The 101 Ash Street conversion faces significant technical challenges that Pacific Beach builders should understand before pursuing similar adaptive reuse projects:

Asbestos Remediation: The building has been vacant since January 2020 when the San Diego County Air Pollution Control District declared it a "Public Nuisance" following repeated violations of dangerous asbestos exposure levels. A 2020 Kitchell consultant review found the building requires up to $115 million in fixes, including $16-25 million specifically for asbestos remediation. City employees occupied the building for only a few weeks in late 2019 before construction work dislodged asbestos, forcing evacuation.

MEP System Conversion: Office buildings like 101 Ash typically use central HVAC systems with large air handlers and minimal zone control. Residential building code requires individual unit climate control, necessitating extensive ductwork modifications or complete system replacement. Commercial-to-residential conversions in San Diego typically cost $300,000 to $500,000+ per unit, with MEP replacement adding 25%-40% over retrofit costs—costs that would be similar for adaptive reuse projects in La Jolla or Bird Rock, though coastal projects face additional marine air corrosion protection requirements.

Building Code Compliance: Bringing a 1968 structure into 2026 code compliance requires seismic upgrades, accessibility improvements (ADA compliance), energy efficiency enhancements (Title 24), and fire safety system modernization. California recently adopted provisions of the International Existing Building Code (IEBC) that provide more flexibility for adaptive reuse, but significant structural and systems work remains necessary under the 2025 California Building Code.

High-Rise Logistics: Construction in a dense downtown environment presents logistic challenges including material delivery coordination, limited staging areas, noise restrictions, and coordination with adjacent occupied buildings—challenges quite different from the low-rise coastal construction Pacific Beach builders typically manage. Projects in Pacific Beach, La Jolla, Mission Beach, and Bird Rock face different constraints including Coastal Commission jurisdiction, ocean proximity setbacks, and neighborhood-specific design review processes. Unlike the downtown high-rise environment, coastal projects near Tourmaline Surfing Park or along the Mission Beach boardwalk often deal with saltwater corrosion, beach access preservation, and coastal erosion mitigation that don't apply to this downtown conversion.

How is this project being financed?

The 101 Ash Street conversion employs a complex affordable housing financing structure that combines multiple funding sources:

Tax-Exempt Bonds: $63.8 million allocation from the California Debt Limit Allocation Committee provides low-cost debt financing.

Low-Income Housing Tax Credits (LIHTC): $82.2 million in tax credit equity ($9.6 million annually for 10 years at 86 cents on the dollar). These federal credits are the primary equity source for affordable housing development.

Ground Lease Payments: The developer (101 Ash Venture LP) will pay the city $45.6 million over 65 years at 5% compound interest, with the first payment deferred for 15 years. This structure reduces initial capital requirements while providing long-term city revenue.

Lender Requirements: The San Diego Foundation and U.S. Department of Housing and Urban Development serve as project lenders, requiring the September 2026 deal amendments (extended lease term and increased interest rate) to approve financing.

Remaining Gap: As of June 2026, the development team was working to close a roughly $8 million financing gap created by tax credit policy changes. Additional competitive grants and tax credits filed in September 2026 aim to bridge this gap.

This financing model demonstrates how affordable housing projects layer multiple sources to achieve feasibility—a technique applicable to other adaptive reuse projects Pacific Beach builders might pursue.

What can Pacific Beach, La Jolla, and Mission Beach builders learn from this downtown adaptive reuse project?

The 101 Ash Street conversion offers several valuable lessons for builders serving Pacific Beach, La Jolla, Mission Beach, and Bird Rock who are considering downtown diversification:

Adaptive Reuse Opportunities: Downtown San Diego's office vacancy crisis creates a pipeline of conversion candidates. Buildings originally designed for commercial use can be transformed into residential projects, though technical challenges (MEP, code compliance, environmental remediation) require specialized expertise. Builders in Pacific Beach, Mission Beach, La Jolla, and Bird Rock can apply lessons from ADU development and coastal infill projects near Tourmaline Surfing Park to adaptive reuse projects.

Political Navigation: The 101 Ash scandal—involving Jason Hughes's guilty plea in 2023 for conflict of interest charges and $9.4 million in undisclosed commissions—created intense political scrutiny. The project survived because it addressed a critical community need (affordable housing) and involved transparent deal restructuring. Builders working on controversial projects in Mission Beach, Bird Rock, or other coastal communities must prioritize transparency and public benefit when facing community opposition or regulatory challenges.

Financing Complexity: Affordable housing development requires expertise in LIHTC, tax-exempt bonds, ground leases, and coordination with mission-driven lenders like the San Diego Foundation. Builders serving Pacific Beach, La Jolla, and Mission Beach who are seeking to diversify into affordable housing should partner with experienced affordable housing developers or invest in learning these financing mechanisms.

Ground Lease vs. Fee Simple: The 65-year ground lease structure reduces initial capital requirements but creates long-term obligations and affects exit strategies. Understanding when ground leases make economic sense versus fee simple ownership is critical for project feasibility.

Downtown vs. Coastal Differences: The 0.55 parking ratio (138 spaces for 252 units) would be unthinkable in Pacific Beach, La Jolla, Mission Beach, or Bird Rock, where coastal parking requirements are significantly higher due to beach visitor demand and limited street parking near landmarks like Crystal Pier and La Jolla Cove. For builders working in Pacific Beach, Mission Beach, Bird Rock, and La Jolla, understanding downtown parking ratios versus coastal requirements provides context for negotiating parking variances in transit-accessible coastal areas near Tourmaline Surfing Park or along the Mission Beach boardwalk. Builders must understand how downtown zoning, parking requirements, and construction logistics differ from coastal environments. Projects in transit-oriented development zones often have reduced parking requirements.

When will construction begin and what timeline lessons apply to San Diego coastal builders?

According to the current project timeline, construction is expected to begin in May 2026 and be completed in May 2028—a 24-month construction schedule that offers timeline benchmarking for large-scale conversions in San Diego County, including potential future projects in coastal communities. However, this timeline depends on successfully closing the remaining $8 million financing gap through competitive tax credits and grants filed in September 2026.

The fall 2026 deal closure targets suggest that if financing closes on schedule, the May 2026 construction start could shift slightly to summer 2026. The developers—MRK Partners (headquartered in Los Angeles and Boca Raton) and cREate Development (owned by San Diego Planning Commissioner Kelly Moden)—have extensive affordable housing experience, though the 101 Ash project's political sensitivity and technical challenges make the timeline subject to potential delays.

Builders serving Pacific Beach, Mission Beach, La Jolla, Bird Rock, and Tourmaline Surfing Park areas should monitor this project's progress as a case study in large-scale adaptive reuse, asbestos remediation execution, and affordable housing delivery in downtown San Diego. The successful transformation of San Diego's most notorious real estate scandal into 252 affordable homes would demonstrate the viability of office-to-residential conversions and potentially open additional downtown opportunities for experienced builders, while also informing adaptive reuse strategies for underutilized commercial buildings in coastal communities.

Conclusion

The 101 Ash Street conversion represents a turning point for downtown San Diego, transforming a vacant, asbestos-contaminated office tower into critically needed affordable housing. For builders serving Pacific Beach, La Jolla, Mission Beach, Bird Rock, and the Tourmaline Surfing Park area, the project demonstrates both the opportunities and challenges of adaptive reuse: complex financing structures, rigorous environmental remediation, building code compliance challenges, and the necessity of political transparency.

As the project moves toward its May 2026 construction start, builders working in Pacific Beach, Mission Beach, La Jolla, and Bird Rock should watch how Kelly Moden's team navigates asbestos abatement, MEP system conversion, and high-rise residential construction logistics. The lessons learned from 101 Ash Street will inform future office-to-residential conversions throughout San Diego, potentially creating new opportunities for builders willing to diversify beyond coastal low-rise construction near Crystal Pier, La Jolla Cove, or the Mission Beach boardwalk into downtown adaptive reuse projects.
