What Is Industrial Outdoor Storage (IOS)?
Industrial Outdoor Storage refers to low-coverage sites—typically paved or graveled land parcels with minor office or warehouse structures—optimized for the storage of vehicles, containers, trailers, construction equipment, and materials. These properties differ radically from traditional warehouses, prioritizing open, secure, and accessible outdoor yards over expensive structures. As Denver’s infrastructure construction boom continues and supply chain realignment persists, IOS properties have become essential components of the industrial ecosystem.
Denver’s 2025 Market Drivers for IOS Demand
- Construction and Infrastructure Expansion: The $1.2 trillion federal infrastructure package and Colorado’s aggressive highway and transit upgrades have supercharged the need for secure equipment yards, pipe laydown areas, and aggregate/material staging near project sites.
- Limited Industrial Land within Metro Denver: Denver’s industrial vacancy is at record lows (sub-3% for functional IOS), with developers scrambling for appropriate parcels near major thoroughfares such as I-70, I-25, and E-470.
- Supply Chain Resilience and Just-In-Case Inventory: Corporations are rediscovering the value of strategic outdoor storage to buffer against delivery lags and construction lead times.
Case Study: Delivering for Denver’s Construction Sector
Consider the Commerce City Heavy Equipment Storage Yard—a recent 12-acre IOS acquisition offering minimal structures (1,800-square-foot office), security fencing, lighting, and reinforced paving. National contractors such as Kiewit and Mortenson use it to stage aerial lifts, cranes, and utility vehicles at arm’s reach of their I-270 projects. The operator’s triple-net lease yields over $220,000 annual net operating income with virtually no landlord expenses, demonstrating unmatched cash-on-cash returns compared to traditional warehouse leases.

Further IOS Facility Use Cases in Denver
- Utility Contractor Laydown Yards: Storing electrical transformers, concrete vaults, and directional drilling rigs while projects cycle through regulatory permitting.
- Vertical Construction Support: Staging steel, modular units, and formwork for Denver’s downtown high-rises and suburban multifamily developments.
- Storm Recovery & Equipment Deployment: Mobile fleets for rapid response to hail, blizzard, and wildfire events across the Front Range.
Cash Flow Potential of IOS Sites
Don’t let the lack of buildings fool you: income from Denver-area IOS yards commonly ranges from $3,000–$6,000 per usable acre per month—and even higher for specialized, paved, well-lit, or rail-served parcels. Tenants are often national tenants with AAA credit, especially those serving major state and federal projects. This increased certainty of cash flow, combined with minimal ongoing costs, translates to NOI margins that can outperform traditionally improved industrial assets.
Zoning Restrictions & Regulatory Hurdles
The greatest headwind to new IOS supply in Denver comes from restrictive zoning laws. Most municipalities—including Denver, Aurora, and Lakewood—have tightly limited where outside equipment, vehicle, or material storage is permitted:
- Industrial Zoning Only: IOS uses are generally restricted to heavy or light industrial zones (I-2, I-3 in Denver), with strict screening, fencing, and environmental requirements.
- Special Use/Condition Use Permits: Many IOS sites require special permission, which can add months to development timelines.
- Environmental Compliance: Paving, stormwater management, and dust mitigation are closely monitored—especially on redevelopment sites with legacy environmental issues.
Investors must closely evaluate title, land use, and approved entitlements before acquisition, often partnering with local consultants and attorneys to streamline the application process.
Development Challenges Unique to IOS
- Infrastructure Investment: High-quality surfacing (asphalt, concrete), security fencing, and lighting can carry upfront costs of $400,000–$1.5 million per 10-acre site depending on standards.
- Utility Limitations: Many IOS parcels lack sewer, water, or power, constraining tenant mix (e.g., no on-site truck repair without utilities).
- Permanent vs. Temporary Structures: City codes may limit the use of temporary storage containers or modular offices. Permanent buildings can invite higher taxes or trigger additional code compliance challenges.
2025 Trends Making IOS a Hot Investment
1. Increasing Construction Pipeline
Denver’s 2025 construction backlog is robust, with $11B+ in public sector transportation, utilities, and renewables work underway. National REITs and regional family offices are acquiring well-located IOS parcels to develop long-term relationships with infrastructure contractors.
2. Emergence of “No Building” Real Estate Funds
Real estate investment platforms dedicated solely to low-coverage IOS portfolios are raising record capital, attracted by both stability (duration of infrastructure project leases) and outsized yields (often 200-500bps over core warehouse cap rates).
3. Tech-Enabled Yard Management
Operators now deploy security cameras, yard management systems, and digital access controls to attract top-tier tenants and command premium rents.
Overcoming Financing Hurdles: Bank Lending & No-Building Bias
Despite tremendous real-world demand, traditional banks remain skittish on lending against IOS property values due to their “no building, low improvement” profile. Appraisers are often skeptical, relying on cost-approach valuations that ignore the true cash flow value IOS can generate. As a result:
- Banks typically limit LTV to 50-60%.
- Underwriting often discounts site improvement cost as non-durable.
- Shorter terms and full recourse are often required.
The Rise of Private Credit & Bridge Lenders in IOS
To fill this gap, private credit funds and specialty bridge lenders are aggressively targeting Denver’s IOS sector. These lenders understand cash flow and tenant quality, often providing:
- 75%+ LTV on stabilized IOS assets, with flexible interest-only terms up to 5 years
- Non-recourse structures for proven operators
- Construction/tenant improvement reserves for paving, lighting, and utility upgrades
Interest rates for private credit IOS loans in Denver now run 200–400bps over prime, but fast approvals and certainty of close empower investors to win competitive deals.
SBA 504: The Unsung Hero for Contractor-Owner Purchases
Many local contractors are turning to the SBA 504 program to acquire their own IOS sites, locking in up to 90% financing with long-term, fixed rates. Unlike many bank programs, the SBA recognizes operational yards as “owner-occupied” businesses, allowing users to:
- Buy a $2M site with only $200K down
- Finance paving, fencing, lighting, and modular buildings as part of project costs
- Enjoy 25-year amortization with certainty of payments
This approach has empowered dozens of Denver-area construction firms to anchor their growth and capture property appreciation amid a development-scarce market.
Local Zoning and Logistics Hotspots
Denver’s most robust IOS clusters are concentrated in:
- Commerce City / North Denver: Proximity to I-270, rail access, and historic refining/transport district
- East Aurora and Watkins: Larger parcels, lower price/acre, near DIA and E-470
- South Adams County: Industrial corridors with legacy transportation and construction tenant base
Understanding local rules—such as Commerce City’s lenient outdoor storage regulations versus Denver’s requirement for full-site paving and landscaping—can make or break a development deal. Investors are advised to:
– Consult with municipal planning staff before contracting
– Budget for compliance upgrades, screening, and permitting timelines
– Pursue long-term leases with creditworthy tenants to underwrite above-average returns
Actionable Insights for IOS Investors, Developers, and Lenders
- Prioritize Sites with Existing Zoning Entitlements: Enables faster deployment and lease-up versus speculative rezoning.
- Partner with Established Contractors: Secure multi-year leases for stable NOI, or JV for long-term wealth creation via sale-leaseback.
- Document NOI Thoroughly: Build a clear income and expense record for appraisers and lenders to maximize future refinancing options.
- Leverage Private Credit & SBA 504: Aggressive financing can turbocharge returns and free up capital for further acquisitions.
- Future-Proof Sites with Tech and Security: Enhanced amenities attract blue-chip tenants and support rent growth.
Conclusion: The Future of IOS in Denver
As supply chain volatility and construction spending reshape Denver’s industrial economy, IOS assets have emerged as some of the region’s most dynamic investment opportunities. With the right zoning and operational partners, minimally improved outdoor storage sites are delivering exceptional cash flow, robust tenant demand, and long-term appreciation in 2025. Investors, developers, and lenders willing to look beyond buildings—and embrace the unique challenges of IOS—are poised for exceptional returns in the decade ahead.
