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.

In the 12 months to October 2026, the Department of Buildings issued first permits for 3,578 interior build-outs in 989 of the 1,708 office buildings Leasemark tracks in New York City, with work permitted on 5,576 floors in all. Their filed cost estimates add up to about $5949 million. The most were at One Penn Plaza, 250 West 34th Street (36 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.
