Source: NYC Department of Buildings, DOB NOW: Build Approved Permits, pulled 2026-10-02 (permits issued through 2026-09-30).

Costs are the estimates filed with the jobs. Jobs filed before DOB NOW (in the older BIS system) are not counted. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
