Flex Space for Lease in Connecticut

Flex space is the hardest product to find on this stretch of the Connecticut shoreline and the easiest to get wrong. Most of what gets advertised as flex is office with a back door, or warehouse with a desk in the corner. Real flex puts people and product under one roof in a ratio you choose, and lets you change that ratio when the business changes.

I am a licensed real estate salesperson with Switz Real Estate Associates Inc. The largest block of genuine flex availability in southeastern Connecticut is Eastport North in Old Lyme, which I represent. Below is what is available there, what makes it work, and what to check before you sign any flex lease.

What Flex Space Actually Means

A flex building carries finished office and clear-span work area behind the same envelope, with its own entrance, its own loading, and zoning that permits light industrial use. The label tells you almost nothing on its own. The specifications do: clear height at the low point, drive-in versus dock loading, available power, floor load, column spacing, parking ratio, and how much of the office is already built. Two buildings marketed with the same word can sit forty percent apart on occupancy cost once you account for what you have to build.

Available Flex Space in Connecticut

Eastport North Commercial Park sits at 6 to 10 Vista Drive in Old Lyme, four buildings on 11.62 acres directly off I-95 Exit 70 at Route 156. Built in 1986 and zoned LI80, the park currently has eight spaces available totaling 27,972 square feet, from 500 square feet of ground-floor office up to a 6,658 square foot warehouse. Clear heights run 22 feet, with drive-in doors, loading docks, and dock levelers in select buildings, and roughly 70,000 square feet of paved, lit parking across the campus.

Three combinations cover most requirements. WH 6 is 6,658 square feet of warehouse at the east end of Building 6 with 22-foot clear height and two loading docks, one of them self-leveling, and it is available January 1, 2027. Suite 611 adjoins it with 500 square feet of ground-floor office, and the two lease together as a 7,158 square foot office and warehouse unit. WH 10B offers 4,014 square feet of warehouse in Building 10. Suite 1020 is 4,110 square feet of second-floor office available now. The office and flex suites across Buildings 6, 7, and 8 run 2,570 to 3,704 square feet, several with partitions already in place.

Base rent is negotiable and structured to the suite, the term, and the improvement package. Estimated 2026 operating expenses are $5.75 PSF, billed separately from base rent. The suite-by-suite breakdown is on the Eastport North listing page.

Why Eastport North Works for Flex Users

Exit 70 is most of the argument. The park is immediately off the interchange, which puts a tenant within a straight shot of New Haven, New London, and the Rhode Island line without a mile of local road first. For a service contractor dispatching trucks or a distributor running a small fleet, that access is worth more than the rent difference to a cheaper inland address.

One campus, several sizes. A tenant who takes 2,570 square feet and grows does not have to leave. Four buildings under one ownership means the next size up is usually available on the same site, on the same lease form, with the same landlord.

Twenty-two foot clear is unusual for the vintage. Much of the 1980s flex inventory in this region tops out well below that. The extra height is what makes real racking possible, and it is the specification most often missing when a tenant compares two buildings on rent alone.

LI80 zoning is broad. The zone supports office, service, and light industrial use in the same park, which matters when your business does two of those things and a narrower zone would force you to choose one.

Operating expenses are low and stated. At $5.75 PSF estimated for 2026, the expense load here runs well below the anchored retail inventory in this region, where nine dollars and up is common. On a flex requirement, that difference compounds across a five or ten year term.

What to Check Before You Sign a Flex Lease

Measure clear height at the low point rather than at the ridge, because the sprinkler main and the light fixtures are what actually limit your racking. Confirm whether loading is drive-in or dock, and at what height, since a truck that cannot reach your door is an expense you pay for every week. Get available amperage and service in writing before you commit to equipment. Ask about floor load and column spacing if you are racking or running machinery. Establish who builds the office finish, who pays for it, and whether that cost is amortized into rent. Then confirm with the town that your specific use is permitted as of right rather than by special permit, because a special permit is a calendar problem, not a paperwork problem.

Where Else Flex Space Shows Up in This Region

Outside Old Lyme, flex inventory in southeastern Connecticut is thin and it moves quietly. Groton has limited dock-served warehouse and contractor space that rarely reaches a listing site. Norwich carries a large inventory, though much of it is older mill building rather than modern flex, and the city owned utilities make it worth a look for a power-hungry user. Waterford has contractor and service inventory that does not sit long. New London has marine and service space near the harbor rather than distribution product. If your requirement does not fit Eastport North, tell me the clear height, power, and yard you need and I will canvass all four off-market.

Common Questions

What does flex space cost in Connecticut?

Less than retail and more than raw warehouse, and the spread depends almost entirely on how much finished office sits inside the envelope. At Eastport North base rent is set per suite rather than published as one number, because 500 square feet of built-out office and a 6,658 square foot warehouse are not the same product. What I will tell you up front is the operating expense line, $5.75 PSF estimated for 2026. That is the number tenants most often forget to ask for and most often get surprised by.

How much flex space is available in southeastern Connecticut?

Not much, and the honest answer is that Eastport North is most of it. There are 27,972 square feet available across the park today. Regionally, modern flex with real clear height and dock loading is scarce enough that a tenant with a firm requirement should be canvassing off-market rather than waiting for a listing to appear.

Can I lease office and warehouse separately?

Yes, and at Eastport North you can do either. WH 6 and Suite 611 are offered separately and lease together as a single 7,158 square foot office and warehouse unit. Suite 610 is a separate 3,049 square foot office and flex space at the other end of the same building. Configurations and combinations are subject to landlord approval, so bring the requirement early rather than after you have set a move date.

Do I need my own representation as a tenant?

Yes, and it generally costs you nothing. In most commercial transactions the landlord pays the fee and it is shared with the firm representing the tenant. Without your own representation you are negotiating against a party whose duty runs to the other side of the table.
