Cold storage costs roughly $130 to $350 per square foot to build, compared with $85 to $150 per square foot for a dry warehouse. That range comes from Newmark's 1H 2026 U.S. Cold Storage Market Overview, as reported by Material Handling & Logistics on September 1, 2026. It is the most recent published national range from a named brokerage, and it is the number to anchor on when someone asks what cold storage construction cost per square foot looks like in 2026.
The width of that range is the first thing to understand. A cooler holding produce at a few degrees above freezing and a deep-freeze building with high-bay automation are both "cold storage," and they do not cost the same. Newmark publishes the range, not a breakdown by temperature class, so this article does not invent one. What it does is walk through the systems that put a refrigerated building well above a dry box, so you can tell where a given project should land inside the range and which line items to question when a bid looks light.
If you want the market side of the story (vacancy, absorption, who is still building), we covered that in cold storage facilities are the next warehouse, which draws on the same Newmark data.
The Published Numbers for 2026
Here is what the September 2026 MH&L summary of Newmark's report actually says, in one place:
| Measure | Value | Source |
|---|---|---|
| Cold storage construction cost | About $130 to $350 per SF | Newmark 1H 2026, via MH&L, Sept 1, 2026 |
| Dry warehouse construction cost | About $85 to $150 per SF | Same |
| National cold storage vacancy | 7.7% | Same |
| Weighted average taking rent, 2026 year to date | $27.40 per SF | Same |
| 1H 2026 move-outs vs deliveries | About 56 million vs 41 million cubic feet | Same |
Two things follow from that table. First, the low end of the cold range ($130) sits inside the dry warehouse range, and the high end ($350) is more than double the top of the dry range. Most of that spread is explained by temperature class, clear height and automation, which we get into below. Second, the market is soft. Newmark recorded the first negative first-half net absorption since 2007, and MH&L reported that the economics are "pushing new pipeline activity toward build-to-suit, owner-user and pre-leased projects." That matters for pricing: fewer speculative freezers in the pipeline means more of the work out there is owner-driven, where specs tend to be tighter and redundancy requirements higher.
For cost movement, the Bureau of Labor Statistics producer price index for new warehouse building construction (series PCU236221236221 on FRED) stood at 244.738 in September 2026, up from 234.183 in September 2025, an increase of about 4.5% in a year. That index tracks dry warehouse contractors' selling prices, not cold storage specifically, but it is the closest official measure of how fast the shell side of these buildings is getting more expensive.
Why Cold Storage Costs More Than a Dry Warehouse
A dry warehouse is a slab, a structure, a roof, walls and dock doors. Cold storage is all of that plus a building that has to hold a set temperature around the clock for decades while the outside air and the ground underneath work against it. Each of the items below adds cost a dry building never carries.
The insulated envelope
Dry warehouse walls are usually tilt-up concrete or single-skin metal panel, and a little air leakage does not matter. Cold storage walls and roofs are typically insulated metal panels with a foam core, and the ceiling or roof assembly carries its own insulation. The panels have to seal continuously at every joint, corner and penetration. A gap in the thermal envelope is not just an energy loss; in a cold building it becomes a condensation point, and in a freezer it becomes an ice point.
Vapor control
Warm, humid outside air pushes toward the cold interior. If moisture gets into the wall or roof assembly and reaches its dew point, it condenses, and below freezing it turns to ice that builds up over time. The vapor barrier on the warm side of the insulation, and the detailing at every seam and penetration, is the scope that experienced cold storage builders treat as quality-control work rather than a commodity line. A failed envelope on a loaded freezer is an expensive callback.
The floor and what is under it
A freezer slab sits on top of soil that will eventually freeze if nothing stops the cold from moving down. Frozen soil expands and can heave the slab, crack it and throw racking out of plumb. Freezer floors therefore get rigid insulation under the slab and an under-floor heating system, usually glycol loops or electric heat, to keep the ground above freezing. Coolers held above freezing face less risk and are designed case by case. For the dry baseline on slab work, our concrete flatwork cost per square foot guide covers the plain-slab side; a freezer floor is that plus insulation, heating and tighter joint detailing.
The refrigeration plant
The mechanical refrigeration system has no equivalent in a dry warehouse and is usually the largest cold-specific line item. Larger facilities often use ammonia (R-717) because of its efficiency. Ammonia also brings regulatory scope. Under OSHA's Process Safety Management standard, 29 CFR 1910.119, Appendix A lists anhydrous ammonia with a threshold quantity of 10,000 pounds. EPA's Risk Management Program list at 40 CFR 68.130 uses the same 10,000-pound threshold for anhydrous ammonia. A system over those quantities brings process hazard analysis, written operating procedures, mechanical integrity programs and related documentation, which add engineering and owner costs on top of the equipment itself. Smaller plants, CO2 systems and packaged units can stay under those thresholds, which is one reason refrigerant choice is a budget decision and not only an engineering one.
Standby power
A dry warehouse that loses power loses lights. A freezer that loses power for long enough loses its inventory. Cold storage owners usually want standby generation sized to the refrigeration load, along with transfer equipment and, on critical buildings, redundancy in compressors. Pharma cold rooms push this further. The MH&L summary of Newmark's report notes that GLP-1 and biologics volumes "are driving billions of dollars of specialized pharmaceutical cold-chain investment," and that kind of space comes with tighter temperature tolerances, mapping and validation.
Where a Project Lands Inside $130 to $350
Since Newmark gives one range rather than a breakdown, the useful question is which features push a building toward each end. These are the main ones, roughly in order of impact.
Temperature class
The colder the room, the more refrigeration capacity, the thicker the insulation and the more likely the floor needs heating. A building that is mostly cooler space with a modest freezer section belongs nearer the bottom of the range. A building that is mostly deep freeze, or includes blast-freezing rooms, belongs nearer the top.
Clear height and automation
Tall, dense freezers cost more per square foot of floor but less per pallet position, because you are refrigerating fewer cubic feet per unit of storage. Automated storage and retrieval systems drive the per-square-foot figure up and change the structural design, since racking can be part of the building structure. Ask whether a quoted number includes the automation package or carries it separately; it is often bought on a separate contract.
Mix of uses
Many cold buildings include dry dock space, offices, battery charging and mechanical rooms. A building that is 60% refrigerated and 40% dry will price very differently from one that is all freezer, even if both are called cold storage.
Market and labor
The Newmark range is national. Local labor rates, refrigeration contractor availability and utility service capacity all shift where a given building lands. Large refrigeration loads can also require utility upgrades that are paid by the owner and often sit outside the building contract.
Reading a Cold Storage Bid
The most common problem with early cold storage budgets is that they treat refrigeration and envelope as a single "mechanical" allowance. That makes it hard to compare bids and easy to miss scope. Ask for these as separate lines:
- Insulated envelope (walls, roof or ceiling, doors and seals)
- Vapor control and envelope detailing
- Under-slab insulation and floor heating
- Refrigeration plant, including refrigerant choice and any PSM or RMP compliance work
- Standby power and transfer equipment
- Automation or racking, if any, and whether it is in or out of the contract
Then compare the total with the Newmark range. A cold building priced inside the dry warehouse range ($85 to $150 per SF) is either mostly cooler space with modest specs or missing something. A building priced far above $350 needs a reason, such as heavy automation, pharma validation or unusual site costs.
When you build up your own number, keep each of those six items as its own lever in the construction cost estimator, and run the schedule through the escalation calculator if the project will not break ground for a year or more. With the warehouse construction PPI up about 4.5% over the 12 months to September 2026, a budget priced today and bid next year will likely need an escalation line.
For comparison with the other big systems-driven building type, our data center construction cost per square foot article covers a building where, as with cold storage, the mechanical and electrical package drives the budget more than the shell does.

Frequently Asked Questions
How much does cold storage cost to build per square foot in 2026?
Newmark's 1H 2026 U.S. Cold Storage Market Overview, as reported by Material Handling & Logistics on September 1, 2026, puts cold storage construction at roughly $130 to $350 per square foot. Temperature class, clear height, automation and the share of the building that is refrigerated decide where a project lands inside that range.
How does that compare with a dry warehouse?
The same Newmark report puts dry warehouse construction at about $85 to $150 per square foot. The low end of the cold storage range overlaps with the dry range, which reflects simpler cooler buildings; the high end is more than twice the top of the dry range.
What makes cold storage more expensive than a dry warehouse?
Systems a dry building does not need: an insulated envelope with careful vapor control, insulated and heated floors in freezer areas, a mechanical refrigeration plant, and standby power sized to protect inventory. Ammonia systems over 10,000 pounds also fall under OSHA Process Safety Management (29 CFR 1910.119) and EPA's Risk Management Program (40 CFR 68.130), which add compliance work.
Do freezers need under-slab heating?
Freezer floors are normally insulated and heated to keep the soil below from freezing. Frozen soil expands and can heave the slab, crack it and knock racking out of alignment. Coolers held above freezing are designed case by case.
Is now a good time to build cold storage?
That depends on the project type. Newmark measured 7.7% national cold storage vacancy and the first negative first-half absorption since 2007 in 1H 2026, and MH&L reported that new pipeline activity is shifting toward build-to-suit, owner-user and pre-leased projects. Speculative freezers are harder to finance right now; owner-driven projects are where most of the current work is.
