The Shallow-Bay Thesis Is Holding Up Where It Matters Most
A lot of industrial product has come to market over the past several years, but not all of it is created equal. While big-box distribution facilities in secondary and tertiary markets have begun to show early signs of softening, the shallow-bay, multi-tenant infill segment is telling a markedly different story. For investors and developers who positioned in supply-constrained urban and suburban cores, the fundamentals heading into mid-2026 remain among the most resilient across all commercial real estate property types. This week we want to unpack why that divergence is widening, and what it means for deals currently in predevelopment or moving toward entitlement.
Shallow-bay industrial, broadly defined as single-story product with bay depths in the range of 80 to 130 feet and suite sizes typically running from a few thousand to roughly 20,000 square feet, serves a fundamentally different tenant profile than regional distribution. Last-mile delivery operators, specialty contractors, medical supply distributors, creative fabricators, and light manufacturers are not interchangeable with large-format logistics users. Their location sensitivity is acute, their tolerance for long commutes from suburban greenfield sites is low, and their ability to relocate is constrained by workforce proximity, zoning compatibility, and infrastructure access.
Supply Constraints Are Doing the Heavy Lifting on Rent
In the metros where this dynamic is most pronounced, including coastal California submarkets, infill pockets across the Mid-Atlantic, supply-locked corridors in the Pacific Northwest, and select Sun Belt nodes that have exhausted developable land near urban employment centers, new shallow-bay deliveries remain structurally limited. Entitlement timelines in many of these markets have lengthened considerably over the past several years. Land basis in infill locations has made speculative development pencil harder without meaningful pre-leasing. Environmental review, community opposition, and competing land use pressure from residential and mixed-use developers all compound the supply picture.
The result is that vacancy in well-located shallow-bay product across these markets has stayed compressed, with effective rents continuing to grind higher on a net basis. Renewal spreads on expiring leases have remained well above historical norms in many of these pockets, and landlords are reporting fewer concession requests from tenants compared to the broader industrial market. When a tenant's operation is tied to a specific labor pool, customer base, or last-mile route, the cost of relocation frequently exceeds the cost of absorbing a rent increase. That calculus is the structural engine behind tenant stickiness in this segment.
What Tenant Stickiness Actually Means for Underwriting
Capital markets participants have taken note. Lenders across the spectrum, including specialty debt funds, regional banks with strong industrial appetite, and in some cases life insurance companies comfortable with infill industrial credit, have remained constructive on shallow-bay infill deals in supply-constrained markets. Underwriting standards have tightened meaningfully from the peak of the cycle, particularly around stress-tested debt yields and exit cap assumptions, but well-located product with demonstrated multi-tenant occupancy and granular lease rolodex diversity continues to attract competitive terms relative to other CRE categories.
For developers, the tenant stickiness argument translates directly into underwriting durability. A rent roll with 15 to 25 tenants across a range of lease expirations, operating in businesses that are functionally tethered to the submarket, is a very different credit story than a single-tenant big-box with a near-term lease maturity. That granularity lowers event risk, supports lender confidence in net operating income stability, and often allows for more constructive conversations around loan sizing and structure. Equity partners with operating platforms that include active asset management and tenant relationship infrastructure have a measurable edge in this segment over passive ownership structures.
Positioning Your Deal for the Next Cycle Window
If you are working on a shallow-bay infill project currently in predevelopment, there are a few strategic considerations worth stress-testing now. First, submarket selection within a given metro matters enormously. Not all infill is created equal, and submarkets with demonstrated rent growth, measurable supply barriers, and strong tenant demand drivers from the trade and service sectors will underwrite differently than those benefiting primarily from broad metro tailwinds. Second, site control timelines relative to entitlement duration deserve close attention. Longer entitlement windows mean more capital at risk pre-close, and your equity and debt structure should reflect that. Third, programming decisions around clear heights, loading ratios, and electrical capacity will increasingly influence tenant quality and achievable rent on the next generation of shallow-bay product. Functional obsolescence in this segment is a real underwriting risk as tenant requirements evolve.
The shallow-bay infill story is not a secret at this point, but execution barriers remain high enough that disciplined operators with the right market access, entitlement relationships, and capital structure will continue to find meaningful opportunity in the quarters ahead.
If you have a flex or shallow-bay infill deal in predevelopment or moving through entitlement and you want to think through financing structure early in the process, reach out to the team at CLS CRE. We work with developers and operating partners across the industrial spectrum and can help you identify the right capital stack for where your deal is today and where it is headed.
