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.

You rent the space from the company that leases it now rather than from the landlord, for part of that company's remaining term. Subleases often come built out and furnished, run shorter than a direct lease and usually ask less than comparable direct space. The landlord has to consent in writing before anyone moves in, and the sublease ends when the lease above it does. Leasemark matches sublease listings with tenants looking to lease or sublease.

Usually, with your landlord's written consent: most New York office leases require it, and many let the landlord take the space back instead (recapture) or claim a share of any rent above what you pay. You stay liable under your own lease while the subtenant is in. Read the subletting clause first, then list the space for free on Leasemark, where it is matched against every active requirement for this kind of space.

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 sublease.

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.

Build-outs in every NYC neighborhood

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.
