What's in This Guide
Key Takeaways
- Warehouse rent is quoted in dollars per square foot per year. Multiply by the square footage, divide by twelve, and you have the base monthly rent, before pass-throughs.
- The quoted rate is rarely the total cost. Under an NNN lease you also pay property taxes, insurance, and maintenance on top of base rent.
- Clear height, loading docks, power, office finish, and yard space move the rate as much as location does.
- Connecticut industrial vacancy sat near historic lows along the I-91 and I-95 corridors, at 4.4 percent for Hartford and New Haven combined in late 2025, which keeps the upper hand with landlords.
Warehouse rent has a simple arithmetic and a complicated context. The arithmetic: rates are quoted in dollars per square foot per year, so a 10,000 square foot space quoted at 8 dollars is 80,000 dollars a year, or about 6,667 dollars a month, in base rent. The context: that quoted number is almost never what you actually pay, and in Connecticut's current market, the number itself reflects one of the tightest industrial supplies on record.
How Warehouse Rent Is Quoted
Industrial space in Connecticut is typically quoted per square foot per year, and the lease structure decides what that number includes. Under a gross or modified gross lease, some or all building costs are folded into the rent. Under a triple net (NNN) lease, the most common structure for industrial space, the tenant pays base rent plus a share of property taxes, building insurance, and maintenance.
Two other cost lines belong in the plan: utilities, which the tenant almost always pays directly in industrial space, and any improvements the space needs, from added office to heavier power, which either you fund or the landlord amortizes into the rent.
What Moves the Number
| Variable | Effect on rate |
|---|---|
| Clear height | Taller buildings store more per square foot and command more per square foot |
| Loading docks and drive-ins | More and better doors mean faster freight and higher rents |
| Power | Heavy three-phase service is expensive to add, so buildings that have it charge for it |
| Office percentage | Finished office costs more to build, and pushes the blended rate up |
| Yard and parking | Fenced yard, trailer parking, and outdoor storage carry real value, and sometimes separate rent |
| Size of the space | Small bays rent for more per square foot than big boxes, because demand for them is deepest |
| Location | Highway access along I-91, I-95, and I-84 carries a premium |
The Connecticut Market Right Now
Context explains the quotes you will hear. Cushman and Wakefield's Connecticut MarketBeat reported combined Hartford and New Haven industrial vacancy of 4.4 percent as of the fourth quarter of 2025, with vacancy near historic lows along the I-91 and I-95 corridors (Cushman and Wakefield: Connecticut MarketBeats). Market coverage of central Connecticut points to the same squeeze: steady leasing, limited new construction because building costs remain high, and tenants competing for the inventory that exists (NEREJ: Industrial market update in Central CT).
Practically, that means well-located, functional space rents quickly, small bays are the most competitive segment, and waiting for the perfect quote can cost more than negotiating the right lease on a good building today. When you want current numbers for a specific size and town, ask us for live comparables through Find Commercial Space, or talk through a specific need with our tenant representation team.

What does NNN add to the quoted rent?
Under a triple net lease you pay base rent plus your share of property taxes, building insurance, and maintenance. The size of that addition depends on the building and the town's tax picture, so ask for the current pass-through estimate in writing for any space you are comparing.
Why do small warehouses cost more per square foot?
Because demand is deepest at the small end and supply is thinnest. Contractors, trades, e-commerce operators, and service businesses all want spaces under about 10,000 square feet, and Connecticut has not built much new small-bay product. More competition per space means higher rates per foot.
How do I find out current Connecticut warehouse rates?
Ask a broker for live comparables on the specific size and towns you need. Published averages blur together very different buildings and lease structures. Commercial Connection provides current comparables and the total-cost math for spaces we discuss, at 203-596-7777.
