What is Industrial Outdoor Storage (IOS)?

IOS is fenced, stabilized yard space leased for truck/trailer parking, container storage, and equipment laydown — low-coverage industrial sites (under roughly 20% building coverage) near ports, intermodal ramps, and highways. Rents quote per acre per month (or per trailer stall) rather than per square foot. The class institutionalized after 2020 as e-commerce drayage demand outran a supply that zoning boards rarely add to.

How is IOS performance measured?

Revenue per acre per month is the headline metric (port-adjacent infill commands multiples of rural sites), alongside stall occupancy, paved-vs-gravel mix (paving supports higher rents), and building coverage ratio. Environmental status matters more than in most classes: prior industrial uses make a clean Phase I ESA a genuine value driver.

Are there REITs for industrial outdoor storage?

No pure-play IOS REIT exists yet. Institutional capital reaches IOS through private platforms — Zenith IOS (J.P. Morgan joint venture), Alterra IOS, Industrial Outdoor Ventures, and Outpost — which aggregated the historically mom-and-pop owner base. Public industrial REITs (Prologis PLD, First Industrial FR, Terreno TRNO) hold some low-coverage IOS-like sites within larger portfolios.

Industrial Outdoor Storage KPIs.

Industrial Outdoor Storage (IOS) is fenced, stabilized yard space leased for truck and trailer parking, container storage, construction equipment and materials laydown, and fleet operations — typically low-coverage sites (under 20% building coverage) in infill industrial locations near ports, intermodal ramps, and highway interchanges. Performance is measured in revenue per acre (replacing per-square-foot metrics), yard occupancy by acreage, and per-stall trailer parking rates. The asset class institutionalized rapidly after 2020 — specialist platforms (Zenith IOS with J.P. Morgan, Alterra IOS, Industrial Outdoor Ventures, Outpost) aggregated a fragmented owner base as e-commerce logistics and drayage demand outran supply; zoning boards rarely approve new IOS, making existing sites scarcity assets. Ilora.ai ingests yard lease agreements, per-acre rent rolls, environmental reports (prior industrial uses make Phase I ESAs critical), and stall-utilization data, then benchmarks per-acre revenue against regional IOS comparables.

13 definitions · Sector: INDUSTRIAL · Used by Ilora.ai specialist AI agents

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
PUE: Total facility power divided by IT equipment power. Lower is better — 1.0 is theoretical perfect.
SF Yield: NOI per rentable square foot. Comparable measure across industrial buildings of different size.
Clear Height: Distance from finished floor to lowest overhead obstruction. Drives storage cube and rent premium.
