NYC Department of Finance filings
Rent collected per square foot: office buildings in Manhattan
In 2024, 1,506 Manhattan office properties filed income statements with the city. Their median gross income was $52.08 per square foot, and the middle half collected between $38.22 and $74.58. The typical property's income was up 1% on 2023. The city publishes these figures by borough, not by neighborhood, so they cover Manhattan as a whole.

Owners of income-producing properties file a Real Property Income and Expense statement each year; gross income is everything a property collected in 2024 per square foot, as filed, with outlier and partial-year filers left out. It includes vacant space, concessions and older leases, so it is not an asking rent.

Source: NYC Department of Buildings, DOB NOW: Build Approved Permits, pulled 2026-10-24 (permits issued through 2026-10-22). A build-out groups interior jobs (construction, mechanical, plumbing, sprinklers and the like) on the same floors first permitted within 120 days of each other, dated by its first permit. Only the large buildings Leasemark tracks count (35,000 SF and up), not every permit in the neighborhood. Costs are the estimates filed with the jobs. A permit does not say who the work is for.

Questions about office space in Midtown South
Is there office space for lease in Midtown South right now?
No office space for lease in Midtown South is listed on Leasemark right now. Post what you need and Leasemark matches you the day a space that fits is listed; your contact details stay private until you accept an intro. Owners and brokers can list a space here for free.
How much does office space cost in Midtown South?
Leasemark has no asking rents posted here yet, so here are the city's own numbers. Office buildings in Manhattan collected a median $52.08 per square foot in 2024, and the middle half between $38.22 and $74.58, according to the income and expense statements owners file with the NYC Department of Finance (FY 2027 distributions, 1,506 filings). The city publishes these figures by borough, so this is Manhattan as a whole, not Midtown South alone. That is what buildings actually collected, with vacant space, concessions and leases signed years ago in the mix, so it is a baseline rather than a quote: a specific space's price depends on the building's class, floor, condition and the length of the lease.
How do I find office space in Midtown South that is not publicly listed?
Post a requirement on Leasemark. Owners and listing brokers see what you need (without your contact details) and can respond with spaces, including ones that are not on the market yet. You choose who gets an intro.
How much office space is there in Midtown South?
New York City's PLUTO tax lot data (26v2) records about 28.3 million square feet of office floor area across 398 properties in the part of Midtown South Leasemark covers. The largest by that measure is 338 Fifth Avenue, at about 2.7 million square feet. That is the existing building stock, not space currently for lease.
What subway lines serve Midtown South?
Ten subway stations sit within about 0.5 mi of Midtown South's commercial core, served by the 1, 2, 3, 6, B, D, F, M, N, Q, R and W trains. The closest is 28 St (R W), roughly 1 minute on foot; then 28 St (6), 28 St (1), 23 St (F M), 23 St (R W), 34 St-Herald Sq (B D F M N Q R W), 33 St (6) and 3 more. Walking times are straight-line estimates from MTA station data.
Are offices being built out in Midtown South?
In the 12 months to October 2026, the Department of Buildings issued first permits for 289 interior build-outs in 106 of the 184 office buildings Leasemark tracks in Midtown South, with work permitted on 477 floors in all. Their filed cost estimates add up to about $166 million. The most were at Empire State Building, 338 Fifth Avenue (22 build-outs). A build-out here is interior work on the same floors (construction, mechanical, plumbing, sprinklers and the like) first permitted within 120 days. New interior work usually follows a lease, so it is a rough sign of where tenants are moving in, but a permit does not say who the work is for.
Do tenants in Midtown South pay the NYC Commercial Rent Tax?
Yes, for larger leases. Midtown South is in Manhattan below 96th Street, where the city's Commercial Rent Tax applies. A tenant owes it only when base rent for the space is $250,000 a year or more. The tax is 6% of base rent after a 35% reduction, so 3.9% of rent, with a sliding credit between $250,000 and $300,000, and the Small Business Tax Credit wipes it out for businesses with total income of $5 million or less and base rent under $500,000.
Is it free to post on Leasemark?
Yes. Posting a space or a requirement is free. Contact details are only shared when both sides accept an intro.
