Passerelle Fallbrook: 157,000 SF Office-to-Residential Conversion Creates 138 Condos at SR-76 & I-15 (June 2026)

What Is the Passerelle Project? Office-to-Residential Conversion Details

The Passerelle project involves converting 157,000 square feet of Office Professional Uses designated in the Campus Park Specific Plan into a 138-unit multi-family residential development configured as detached single-family condominiums. The project sits on two parcels totaling approximately 11.96 acres adjacent to Horse Ranch Creek Road and Friesian Way in unincorporated Fallbrook, directly visible from the SR-76 and I-15 interchange—one of North County's most prominent gateway locations.

Project Configuration and Density

The residential development will be split across two parcels:

• Northern Parcel: 35 condominium units
• Southern Parcel: 103 condominium units
• Total Development: 138 detached single-family-style condos
• Total Acreage: 11.96 acres
• Density: Approximately 11.5 units per acre

This density represents a significant increase over the office use originally approved under the Campus Park Specific Plan. While office space generates minimal evening and weekend traffic, 138 residential units will produce an estimated 1,380-1,650 daily vehicle trips based on standard Institute of Transportation Engineers (ITE) trip generation rates for single-family attached housing (10-12 trips per unit daily).

Required Approvals and Planning Process

The Passerelle project required four major land use approvals reviewed by the San Diego County Planning Commission on June 12, 2026:

1. General Plan Amendment (GPA): Modification to the Fallbrook Community Plan to redesignate land use from commercial office to residential
2. Specific Plan Amendment (SPA): Amendment to the Campus Park Specific Plan, which originally designated the parcels for Office Professional Uses totaling 157,000 square feet
3. Revised Tentative Map (TM): Subdivision of a portion of the Campus Park Tentative Map into two residential parcels and a designated remainder parcel on the adjacent Town Center site
4. Site Plan (STP): Development plan along the I-15 Design Review Corridor, subject to enhanced architectural and landscaping standards due to high visibility from the interstate

The Campus Park Specific Plan has been the subject of multiple amendments since its original adoption. In June 2014, the San Diego County Board of Supervisors approved the Campus Park West project, a mixed-use development on 116 acres featuring 283 condominiums, 513,000 square feet of commercial development, 120,000 square feet of industrial use, and 31 acres of biological open space. The Passerelle conversion represents a continuation of this trend toward residential intensification in the Campus Park planning area.

Why Office-to-Residential Conversions Are Accelerating in San Diego County

The Passerelle project is part of a statewide surge in office-to-residential conversions driven by three converging factors: post-pandemic office vacancy rates, California's housing crisis, and new streamlined approval processes.

Statewide Conversion Boom: 70,700 Units in the Pipeline

More than 70,700 housing units from converted offices are slated to deliver in 2025 across the United States, double the previous year's total, according to commercial real estate data analyzed by construction industry researchers. California leads the nation in conversion activity, with policymakers across the state pursuing policy changes that remove barriers to converting older commercial buildings into housing.

Gensler, one of the world's largest architecture firms, called adaptive reuse "the new standard" in its 2026 design forecast, signaling that office-to-residential conversions have shifted from opportunistic plays to mainstream development strategy.

California's Streamlined Approval Process

New California legislation enacted in recent years requires that certain affordability and labor standards are met in exchange for ministerial approval of office-to-housing conversions, potentially accelerating projects in downtown San Diego and other commercial districts. With office vacancy rates increasing substantially in the wake of the COVID-19 pandemic and the housing shortage intensifying, apartment conversions have been on a historic rise for several years.

San Diego's Cost Advantage Over Other California Markets

One notable finding from conversion feasibility studies is that conversion costs in San Francisco are roughly 60% more than San Diego, suggesting that San Diego County may be better positioned financially for office-to-residential conversions compared to other major California cities. Lower conversion costs make projects like Passerelle economically viable even in secondary markets like Fallbrook, where median home prices ($837,000-$968,000 as of April 2026) are significantly below coastal San Diego submarkets.

Fallbrook's First Major Commercial-to-Residential Conversion

The Passerelle project is the first large-scale office-to-residential conversion in Fallbrook's unincorporated area, making it a precedent-setting development that will influence future land use decisions throughout North County's commercial corridors. Property owners with underutilized commercial space along SR-76, Old Highway 395, and other Fallbrook commercial districts now have a roadmap for similar conversions.

Impact on Neighboring Properties: Who Should Consider Selling Now?

Property owners within a half-mile radius of the Passerelle site face a critical decision window between Planning Commission approval (June 12, 2026) and construction commencement (estimated late 2027). This 12-18 month window represents the optimal time to sell if you want to avoid construction-phase discounts and lock in pre-development pricing.

Geographic Impact Zone: Horse Ranch Creek Road and SR-76 Corridor

The highest-impact properties are those with direct frontage or immediate adjacency to:

• Horse Ranch Creek Road (primary access route for 138 units)
• Friesian Way (secondary access)
• SR-76 eastbound/westbound between I-15 and Mission Road (cumulative traffic impact zone)
• Residential subdivisions within 0.25 miles of the northern or southern parcels

Property owners in the Horse Creek Ranch, Horse Creek Ridge, and other nearby subdivisions will experience the most significant changes in traffic patterns, noise levels during construction, and long-term density increases.

Construction Timeline and Property Value Impact Windows

The most significant property value discounts occur during the heavy construction phases (Q4 2027 through Q2 2028) when grading, utilities, foundation work, and road improvements generate maximum disruption. Conventional buyers typically discount properties within 0.25 miles of active construction by 8-15% compared to pre-construction pricing.

Who Should Sell Before Construction Begins?

Immediate Sale Candidates:

1. Retirees and Empty Nesters: If you're 65+ and planning to downsize within the next 3-5 years, selling before construction starts avoids 2-3 years of noise, dust, and truck traffic that disproportionately impacts quality of life for seniors.
2. Remote Workers with Noise Sensitivity: If you work from home and conduct frequent video calls, construction noise from heavy equipment, concrete trucks, and framing crews will disrupt your work environment for 18-24 months.
3. Families with Young Children: Parents with toddlers or elementary-age children may prefer to avoid the safety concerns and outdoor play limitations associated with adjacent construction activity.
4. Property Investors with Other Opportunities: If you own rental properties near the Passerelle site and have capital redeployment opportunities elsewhere, selling at pre-construction peak prices and executing a 1031 exchange into properties in non-construction-impacted areas maximizes portfolio value.
5. Homeowners Planning 2027-2028 Life Transitions: If you anticipate job relocation, family changes, or other moves during the peak construction window, selling now (July-December 2026) captures maximum value before the market prices in construction discounts.

Hold Candidates:

Property owners who should consider holding through construction include:

• Long-term holders (10+ years): Construction is temporary; long-term neighborhood character and property values depend on the quality of the finished development and its integration into the community.
• Homeowners in premium locations: If your property has unique features (view lots, creek frontage, larger parcels) that will retain value regardless of nearby development, short-term construction impact may be worth weathering.
• Investors betting on Fallbrook growth: If you believe Fallbrook's proximity to I-15, lower prices compared to coastal markets, and North County growth trends will drive long-term appreciation exceeding 5-7% annually, holding through construction turbulence may prove profitable.

Cash Buyer Opportunities: Two Distinct Strategies

The Passerelle conversion creates opportunities for two different types of cash buyers: (1) residential buyers targeting pre-construction neighbor properties, and (2) commercial investors seeking similar office-to-residential conversion plays.

Strategy 1: Acquire Neighboring Residential Properties Pre-Construction

Cash buyers can capitalize on the 12-18 month window between Planning Commission approval and construction start by acquiring properties from motivated sellers who want to avoid construction impact. The key advantages of this strategy:

Why Sellers Accept Cash Offers During This Window:

• Certainty and Speed: Property owners facing a multi-year construction timeline value quick closings (7-14 days) and guaranteed transactions without financing contingencies.
• Avoid Disclosure Complications: Once construction begins, sellers must disclose active construction and potential property value impacts to conventional buyers, complicating transactions and reducing buyer pool.
• Pre-Construction Premium: Selling before grading and utilities work begins allows sellers to capture pricing before construction discounts take effect.

Target Properties for Cash Acquisition:

• Single-family homes on Horse Ranch Creek Road within 0.25 miles of Passerelle parcels
• Residential lots with deferred maintenance (owners less likely to invest in repairs with impending construction)
• Estate properties where heirs want liquidity before market conditions deteriorate
• Fix-and-flip opportunities that can be renovated and resold before construction impact intensifies

Strategy 2: Identify Similar Office-to-Residential Conversion Opportunities

Commercial property investors and developers can use the Passerelle project as a blueprint for identifying underutilized office properties suitable for residential conversion throughout Fallbrook and North County.

Characteristics of Conversion-Ready Office Properties:

1. Vacancy or Underutilization: Office buildings with 40%+ vacancy or properties generating below-market rents
2. Zoning Flexibility: Properties within Specific Plan areas or General Plan designations that allow residential uses through amendment
3. Infrastructure Access: Sites with existing water, sewer, and road access reduce conversion costs
4. Proximity to I-15 or SR-76: Transportation corridor locations attract residential buyers seeking commuter access to San Diego, Temecula, and Camp Pendleton
5. Parcels 5-15 Acres: Large enough for meaningful residential projects (50-150 units) but small enough to avoid triggering major environmental review processes

Fallbrook Submarkets with Conversion Potential:

• SR-76 Commercial Corridor (Old Highway 395 to I-15): Multiple aging office and retail centers with high vacancy
• Mission Road Office Parks: Small-scale professional office buildings developed in the 1980s-1990s with outdated floor plans
• Ammunition Road Industrial/Office: Former industrial sites transitioning to mixed-use as Fallbrook's economy shifts from agriculture to residential services

Cash buyers pursuing conversion opportunities should engage land use attorneys and civil engineers early to assess General Plan Amendment feasibility, infrastructure capacity, and environmental constraints before acquisition.

Fallbrook Real Estate Market Context: Pricing and Inventory (2026)

Understanding the Passerelle project's impact requires context on Fallbrook's current real estate market conditions, which show mixed signals in mid-2026.

Median Home Prices: Wide Range Depending on Source and Property Type

Fallbrook median home values vary significantly depending on data source and property characteristics:

• Zillow Home Value Index (April 2026): $837,447, down 3.2% over the past year
• RealtyTrac Median Estimate: $968,150
• Orchard Median Price (Last 30 Days): $951,000, up 16.7% year-over-year
• Recent Median Asking Price: $888,000, down 14.5% over the past 30 days

This variance reflects differences in property types, data collection methodologies, and market timing. Detached single-family homes (which comprise 82% of active Fallbrook listings) average approximately $1.2 million, while condominiums average $575,000.

Market Conditions: Balanced Inventory with Moderate Days on Market

As of June 2026, the Fallbrook real estate market is classified as balanced with the following characteristics:

• Active Listings: 263 properties
• Months of Inventory: 5.7 months (5-6 months = balanced; below 5 = seller's market; above 6 = buyer's market)
• Average Days on Market: 41 days overall; 11 days to pending status
• Price Per Square Foot: $432 average

Condo Market Implications for Passerelle Pricing

With existing Fallbrook condos averaging $575,000 and detached homes averaging $1.2 million, the Passerelle units (configured as detached single-family condos) will likely price in the $700,000-$900,000 range depending on square footage, finishes, and view premiums. This pricing would:

• Provide an entry point below the $1.2 million detached home median
• Target first-time buyers, downsizers, and commuters seeking I-15 access
• Compete with existing Horse Creek Ranch and Horse Creek Ridge communities along SR-76

Planning Commission Review Process and Next Steps

The June 12, 2026, Planning Commission hearing represents one stage in a multi-step approval process that must be completed before construction can begin.

Planning Commission Role and Authority

The San Diego County Planning Commission holds authority to approve, conditionally approve, or deny the General Plan Amendment, Specific Plan Amendment, Tentative Map, and Site Plan for the Passerelle project. The Commission's decision can be appealed to the San Diego County Board of Supervisors within 10 days of the decision date.

Anticipated Approval Timeline

Assuming Planning Commission approval on June 12, 2026, the likely timeline for remaining approvals and construction start:

The 12-18 month window between final approval (September 2026) and construction start (Q4 2027) represents the optimal period for neighboring property owners to make hold-or-sell decisions.

Community Input and Opposition Potential

Large-scale residential projects in Fallbrook have historically faced community opposition focused on traffic, density, and infrastructure capacity concerns. The Fallbrook Community Planning Group and Design Review Board have reviewed the Passerelle project through multiple iterations. Property owners concerned about the project's impact attended Planning Commission hearings and submitted written comments during the public review period.

Key concerns raised in similar Campus Park-area projects include:

• Traffic Congestion: SR-76 and I-15 already experience peak-hour congestion; 138 units add 1,380-1,650 daily trips
• School Capacity: Fallbrook Union Elementary and High School Districts must assess capacity for students from new units
• Water Supply: Fallbrook Public Utility District must confirm adequate water supply during drought conditions
• Wildfire Risk: Fallbrook is in a Very High Fire Hazard Severity Zone; evacuation routes and fire access require scrutiny

Frequently Asked Questions

Conclusion: Act Now to Maximize Your Position Before Construction Begins

The Passerelle office-to-residential conversion represents a watershed moment for Fallbrook's real estate market—the first large-scale commercial-to-residential transformation in the unincorporated North County area that will set precedent for future development along the SR-76 and I-15 corridors. For property owners within the impact zone, the decision window is narrow: the 12-18 months between Planning Commission approval (June 2026) and construction start (late 2027) offer the optimal opportunity to sell before construction discounts take effect.

If you own property on Horse Ranch Creek Road, Friesian Way, or within a half-mile radius of the Passerelle parcels and are considering selling within the next 3-5 years, acting now—before grading equipment and concrete trucks become your daily reality—maximizes your sales price and minimizes transaction complications. Cash buyers specifically target this pre-construction window because motivated sellers value speed and certainty over the uncertainty of holding through 24-30 months of construction disruption.

For commercial property investors and developers, the Passerelle project provides a proven roadmap for identifying underutilized office and industrial properties throughout Fallbrook and North County that can be converted to residential use. With more than 70,700 office-to-residential units in the pipeline nationwide and California's streamlined approval processes, this trend is accelerating—not slowing down.
