The Long Island office market finished the second quarter of 2026 tighter than at any point since the pandemic, and with the highest asking rents ever recorded here. Both of those are true. Neither of them means quite what a headline number usually means, because a meaningful share of the tightening came from buildings leaving the market rather than tenants entering it.

The numbers

CBRE puts Long Island office availability at 12.1 percent for the second quarter, a post-pandemic low and down 250 basis points from a year earlier. Leasing activity reached 436,000 square feet, up 7 percent from the first quarter and 3 percent above the five-year average. Net absorption was positive and asking rents rose.

Newmark, measuring a slightly different inventory, has availability at 11.5 percent, the lowest since the third quarter of 2020, with asking rents up 18 cents to an all-time high of $33.52 per square foot, a gain of 1.8 percent year over year.

The gap between 12.1 and 11.5 is not a contradiction, and it is worth understanding if you are going to read any of these reports. Brokerages track different building sets, count sublease space differently, and draw the boundary of the market in slightly different places. The direction is what matters, and every firm reporting on the quarter has it pointed the same way.

The part that deserves attention

CBRE attributes a share of the tightening to the steady removal of obsolete and underutilized office stock through demolition or conversion, which reduces competing supply and strengthens landlord pricing power.

That is a supply story dressed as a demand story. An availability rate is a fraction. It falls when the numerator shrinks, and the numerator shrinks either because somebody signed a lease or because the building stopped being an office. Long Island has been doing a great deal of the second thing: 1980s suburban office product that no longer competes is being converted to residential and industrial use or taken down entirely.

This is, on the whole, a good outcome. A half-empty office building on a Nassau arterial is a drag on the tax roll, the streetscape and the town around it, and turning it into apartments or a distribution facility is usually the better civic answer. But it changes what a record rent means. Rent rising because more companies want space here is one signal. Rent rising because there is less space to want is a different one, and only the first of the two says the regional economy is expanding.

Industrial is the stronger read

The industrial market is where the demand story is cleaner. Vacancy fell 70 basis points to 7.0 percent. Net absorption topped 800,000 square feet for the quarter. Leasing hit 905,000 square feet, a 43 percent jump from the first quarter, driven by wholesale and retail, e-commerce and logistics tenants, and executed largely through mid-sized deals rather than one outsized signature.

CBRE describes the underlying condition as healthy tenant demand against a limited supply of large-block space, which is the structural fact of industrial real estate on Long Island and has been for a decade. There is no room. Every parcel that could hold a big box is already holding something, and the land that remains is expensive, contested, or over an aquifer.

The labor picture underneath it

Long Island closed the second quarter with unemployment at 3.9 percent, up 40 basis points from the previous quarter but still below the national rate of 4.2 percent. Total nonfarm employment rose 0.4 percent year over year to roughly 1.4 million jobs. Office-using employment added 750 jobs quarter over quarter, with the gains concentrated in information and in professional and business services.

Four tenths of a percent is growth. It is not a boom. Set that against a 250-basis-point drop in office availability and the arithmetic only closes if supply is doing a share of the work, which is exactly what the brokerages say is happening.

What it means if you are signing something

For a tenant, this is the least favorable market in six years, and the leverage has moved. Renewals that would have been a formality in 2022 are negotiations now, concession packages are thinner, and the block of space you were going to expand into next year may not be there. If your lease runs out in 2027, the time to be in the market is well before 2027.

For a landlord holding good product, this is the quarter the last five years were supposed to pay for.

And for a town, every conversion and every demolition inside that availability figure was a separate application, heard by a separate board, decided on its own merits. The regional number is the sum of a few hundred local land use decisions that nobody made as a region. That is worth remembering the next time an office park shows up on a zoning calendar.
