A warehouse is a large commercial building designed to store goods, raw materials, or finished products before they are moved to the next stage of the supply chain — whether that is a retail store, another facility, or a consumer. Warehouses are leased or purchased by manufacturers, distributors, e-commerce operators, importers, and logistics service providers, and range in size from a few thousand to more than one million square feet.
What a warehouse is
In commercial real estate, "warehouse" functions as both a specific property type and a broad category that covers a wide range of industrial buildings. At its most basic, a warehouse is any structure designed to hold physical inventory. In practice, the term describes everything from a simple 5,000 SF storage unit to a million-square-foot automated fulfillment campus.
Most commercially-listed warehouses share a few consistent features: concrete slab floors rated for forklift traffic, dock-high or grade-level loading access, clear heights of at least 18 feet (with modern Class A facilities reaching 36 to 40+ feet), and industrial electrical service.
The category also includes more specialised building types that are all technically warehouses:
- Distribution centers — high-throughput facilities engineered for bulk inbound and sorted outbound freight movement
- Fulfillment centers — direct-to-consumer order processing facilities, common in e-commerce
- Cold storage warehouses — temperature-controlled facilities for perishable food, pharma, or chemicals
- Flex buildings — combined warehouse and office space, often with grade-level doors and lower clear heights
- Cross-dock facilities — pass-through buildings where freight arrives and departs with minimal storage time
How warehouses are leased
The vast majority of industrial warehouse space in the United States is leased on a triple net (NNN) basis — the tenant pays base rent plus property taxes, building insurance, and maintenance costs. Longer lease terms (typically 3–10 years) yield lower per-square-foot rents and often unlock larger tenant improvement allowances.
Key lease metrics to understand before evaluating a warehouse:
| Metric | What it means | Typical range |
|---|---|---|
| Base rent | Annual cost per square foot of rentable area | $6–$25+ /SF/yr NNN (varies by market) |
| Clear height | Usable vertical space to lowest obstruction | 18–24 ft (older), 28–40+ ft (Class A) |
| Dock doors | Number of dock-high truck loading bays | 1 per 5,000–10,000 SF (distribution) |
| Truck court depth | Exterior manoeuvring space for trailers | 130 ft min. for 53-foot trailers |
| TI allowance | Landlord contribution toward fit-out | $5–$50+ /SF depending on lease term |
| CAM charges | Pass-through for shared area costs | $0.50–$2.50 /SF/yr additional |
What to watch for before committing
Not all warehouses are operationally equivalent, even at the same size and price. Before signing a lease, verify these six factors for your specific use case:
Clear height vs racking height
Confirm the clear height is measured to the lowest overhead obstruction — sprinkler heads, lighting, and ductwork all reduce usable vertical space below the roof deck.
Dock count for your throughput
Distribution-heavy operations typically need one dock bay per 5,000–10,000 SF. Too few docks creates receiving and shipping bottlenecks at peak times.
Power capacity
E-commerce, cold chain, and manufacturing users often need three-phase power or high-amperage service not standard in older industrial buildings.
Truck court geometry
130 feet of court depth is the minimum for 53-foot trailers. Less than this forces trucks to pull through — slowing operations at every receiving shift.
Zoning and use permits
Confirm industrial zoning permits your specific use. Food storage, chemicals, hazardous materials, and certain manufacturing activities require additional permits or zoning classifications.
Floor load capacity
High-density racking, heavy manufacturing equipment, and bulk palletised goods all place significant loads on the slab. Verify the floor rating before signing for a heavy-use operation.
When you need to know this
Understanding what a warehouse is — and what distinguishes different warehouse types — matters most at the beginning of a site search. Tenants who start with a clear operational profile (throughput volume, racking height, dock count, power needs) consistently secure better-suited space at better lease terms than tenants who begin by browsing listings without defined requirements.
Common situations where warehouse type and specifications drive the decision:
- E-commerce expansion — requires high clear heights, dense dock counts, and proximity to consumer population centres for last-mile efficiency
- Import distribution — proximity to a port or intermodal hub reduces drayage costs; cross-dock capability helps with import freight flow
- Food and beverage storage — requires food-grade certification, pest control protocols, and often temperature control
- Manufacturing relocation — typically requires heavy power, higher floor load capacity, and potentially crane clearance or specialised utility connections
- 3PL and contract logistics — typically needs flexible racking configurations and high dock-to-floor-area ratios to serve multiple clients
