Industrial outdoor storage is moving from a niche corner of the industrial landscape into a defined institutional asset class, according to Partner Valuation Advisors’ latest Industrial Outdoor Storage Market Report & Outlook. The firm links the sector’s evolution to ongoing e-commerce expansion and strategies aimed at strengthening supply chain resilience, with particular focus on IOS sites positioned near major transportation corridors.
The report, authored by Vytas Norusis, MAI, EVP and national practice lead for IOS at Partner Valuation Advisors, highlights a widening and more diversified tenant mix. In addition to traditional trucking-related uses, tenants now increasingly include construction companies, utilities and renewable energy operators. This broadening user base is described as reducing tenant concentration risk and enhancing the sector’s appeal to a wider range of investors.
Partner Valuation Advisors identifies a distinct two-tier IOS market. At the top end are premium sites featuring by-right zoning, clean environmental profiles and infill locations. These properties are drawing institutional capital and supporting aggressive pricing. By contrast, IOS sites that require repositioning are trading at discounts and are more likely to attract opportunistic capital targeting heavier value-add business plans.
The report characterizes the 2026 outlook for IOS as cautiously optimistic, with current momentum expected to continue through the year. However, it notes several downside risks that investors and lenders are watching closely. These include uncertainty in the broader logistics market, zoning and entitlement hurdles that can slow or derail IOS projects, and the possibility that prime IOS locations could be redeveloped into higher-intensity uses, effectively shrinking available IOS inventory.
At the same time, freight market softness could open up a new pipeline of potential IOS supply. Partner Valuation Advisors points to obsolete truck terminals as one example, suggesting that weaker freight fundamentals may create opportunities to convert underutilized facilities into IOS assets where zoning and site characteristics allow.
The growing institutional focus on IOS and the emergence of a clear quality hierarchy are likely to influence capital flows, pricing and risk assessment across the segment. Stakeholders tracking these dynamics will also be watching how regulatory and zoning outcomes, as well as redevelopment trends, shape both the availability and risk profile of IOS locations.
Industrial investors and operators interested in these themes will see them surface on the conference circuit as well. Connect Industrial Midwest is scheduled for Tuesday afternoon, March 10, 2026, at Joe’s Live in Rosemont, IL, with Prologis Chief Operating Officer Carter Andrus slated for the keynote interview.
