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 Harlem
Is there office space for lease in Harlem right now?
No office space for lease in Harlem is listed on Leasemark right now. Nearby on Leasemark: office space for lease at 783 Madison 4th Floor in the Upper East Side (994 SF, $66.40/SF/yr). 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 Harlem?
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 Harlem 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 Harlem 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 Harlem?
New York City's PLUTO tax lot data (26v2) records about 7.7 million square feet of office floor area across 311 properties in the part of Harlem Leasemark covers. The largest by that measure is 721 Esplanade Gardens Plaza, at about 294,000 square feet. That is the existing building stock, not space currently for lease.
What subway lines serve Harlem?
17 subway stations sit within about 0.6 mi of Harlem's commercial core, served by the 1, 2, 3, 4, 5, 6, A, B, C and D trains. The closest is 145 St (A B C D), roughly 3 minutes on foot; then 116 St (2 3), 125 St (2 3), 125 St (A B C D), 116 St (B C), 135 St (2 3), Harlem-148 St (3) and 10 more. Walking times are straight-line estimates from MTA station data.
Are offices being built out in Harlem?
In the 12 months to October 2026, the Department of Buildings issued first permits for 7 interior build-outs in 5 of the 19 office buildings Leasemark tracks in Harlem, with work permitted on 5 floors in all. Their filed cost estimates add up to about $1.9 million. The most were at 105 West 125th Street (2 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 Harlem pay the NYC Commercial Rent Tax?
No. Harlem is north of 96th Street, and the city repealed the Commercial Rent Tax for premises north of the center line of 96th Street, so a commercial lease here does not pay it at any rent. Space south of 96th Street does.
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.
