How much build-out work is happening in Harlem?

In the 12 months to October 2026, the Department of Buildings issued first permits for 12 interior build-outs in 9 of the 34 large commercial buildings Leasemark tracks in Harlem, with work permitted on 9 floors in all. Their filed cost estimates add up to about $2.6 million. The most were at 100 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.

Build-outs in every NYC neighborhood

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No. Harlem is north of 96th Street, and the city repealed the Commercial Rent Tax for premises north of the center line of 96th Street, so a commercial lease here does not pay it at any rent.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.
