IOS Market Deep Dive: Portland, OR

While leasing has softened, the investment market remains active. Institutional and long-term capital continues to view Portland IOS as a durable asset class supported by irreplaceable infrastructure and long-term supply constraints. Acquisition interest remains elevated, particularly for functional sites with strong access, security, and operational layouts.

TLDR

• Metro profile: Portland remains a critical Pacific Northwest logistics and service hub, supported by a diversified economy, deep freight infrastructure, and a strong base of small and mid-sized industrial operators.

• IOS lease economics: IOS leases initiated during 2024 and 2025 generally range from $6,000 to over $10,000 per acre per month, with most deals clustering near $8,000 per acre per month.

• Supply dynamics: Infill industrial land along the Willamette and Columbia corridors is extremely limited, while fragmented zoning and entitlement complexity continue to restrict new IOS supply.

• Demand drivers: Multimodal connectivity including I-5, I-205, Highway 26, river access, rail networks, the Port of Portland, and proximity to PDX sustains demand from construction, utilities, equipment rental, recycling, forestry, and service-sector users.

• Market outlook: Leasing activity has softened from 2023 highs, but long-term IOS fundamentals remain intact due to constrained supply and durable demand for functional, well-located sites.

Market Overview

Portland’s population growth has cooled from pandemic-era peaks, yet the metro continues to benefit from a diversified economic base, a large concentration of small and mid-sized industrial operators, and sustained public investment across transportation and freight infrastructure. Industrial vacancy has increased modestly as new supply has delivered in outlying submarkets, though core infill areas remain tightly held and highly competitive.

The Portland metro functions as one of the most integrated logistics platforms in the Pacific Northwest. Few regions combine interstate access via I-5, I-205, and I-84, extensive regional rail networks, navigable river access on both the Willamette and Columbia Rivers, a deep-water port, and a major international airport within a single industrial ecosystem. This connectivity supports freight flows between the Pacific Rim, West Coast ports, and inland markets across Oregon, southwest Washington, Idaho, and Montana.

As a result, Portland serves as a critical distribution and service base for cities throughout the Northwest, including Seattle, Tacoma, Vancouver, Salem, Eugene, Bend, and Spokane. This geographic reach has historically supported a wide range of yard-intensive industrial uses that rely on outdoor storage for daily operations.

Looking forward, competition for IOS sites is expected to intensify. Infill land along the Willamette and Columbia corridors is increasingly scarce, zoning standards vary widely across municipalities, and entitlement processes remain complex. These factors reinforce the long-term value of well-located IOS assets and cement Portland’s role as a key West Coast logistics and service hub.

Decades of investment in freight infrastructure have created industrial districts that are difficult to replicate elsewhere. The Harbor and Columbia Corridor submarkets continue to benefit from this legacy, positioning them favorably for future trade activity and evolving logistics models that require flexible, multimodal access.

IOS Market Fundamentals

Portland is a structurally complex IOS market. Infill industrial land suitable for outdoor storage is limited, zoning for yard-intensive uses differs by jurisdiction, and redevelopment pressure continues to reduce legacy IOS inventory across the metro.

Leasing momentum has slowed following a strong run through late 2023. Market participants report that overall leasing velocity has declined in line with broader softness in warehouse demand. Tenant activity has cooled across several IOS submarkets, reflecting a more cautious operating environment for logistics and transportation users.

Despite this near-term slowdown, demand remains most resilient among equipment rental providers, heavy equipment contractors, utilities, environmental services firms, and service-based operators. These users continue to rely on secure, well-configured outdoor storage sites to support daily operations. Trucking firms, by contrast, have been less active as broader logistics volumes normalize post-COVID.

While leasing has softened, the investment market remains active. Institutional and long-term capital continues to view Portland IOS as a durable asset class supported by irreplaceable infrastructure and long-term supply constraints. Acquisition interest remains elevated, particularly for functional sites with strong access, security, and operational layouts.

Even in a slower leasing environment, long-term fundamentals remain intact. Zoning friction, environmental overlays, and redevelopment pressure continue to limit future supply, while essential service industries sustain baseline demand. As a result, high-quality IOS sites continue to outperform, while less competitive properties face increased pricing pressure and concessions.

Supply Constraints and Competitive Positioning

Portland’s IOS constraints mirror patterns seen in other mature West Coast and gateway markets. Environmental regulations, fragmented municipal zoning, and redevelopment incentives combine to limit new yard development. Over time, these constraints favor existing, entitled sites that can accommodate modern operational needs.

Well-located properties with efficient layouts, strong ingress and egress, and proximity to major corridors such as I-5 and I-205 continue to command premium pricing. Even as leasing velocity fluctuates, these assets remain core to the region’s industrial backbone.

Bottom Line

Portland’s IOS market is experiencing short-term leasing softness, but long-term fundamentals remain strong. Scarce infill land, complex zoning, and decades of freight infrastructure investment continue to support the value of well-located outdoor storage sites. For functional IOS assets with strong access and operational characteristics, Portland offers durability driven by structural supply constraints rather than cyclical demand alone.
