Permits & Contractors on File

Live from DOB Permit Issuance, cross-referenced by this job number — the business actually pulling the permit, not necessarily the filing applicant above.

When will this be done?

Reader estimates · beta

Crowd-sourced, not DOB data — the City publishes no official projected completion date for this or any filing. "On time" below is measured against readers' own average estimate, the only real baseline available.

Will it finish on time?

Voting opens once at least one reader submits a completion-date estimate.
