Tishman Construction is licensed by the New York City Department of Buildings as a General Contractor, licence number 2540. DOB records 6,935 permits issued to that licence, at 43 buildings across Brooklyn, Manhattan, Queens and Staten Island. A permit records who was authorised to do the work, which is not the same as who performed every part of it.
The 43 buildings listed on this page are the lots where a permit names this licence and the Department of Finance's tax roll confirms the lot exists. Each links to that building's own record. Buildings whose lot has since been merged or renumbered are left off rather than guessed at.
DOB's licence roster lists General Contractor licence 2540 with the status active, at 100 Park Avenue. Status is the value the city's own roster carries on the day this page was built; check DOB directly before relying on it.
No, and deliberately. New York City publishes violations against buildings, not against contractors: the Environmental Control Board records a respondent name but no licence number, and company names collide — two separately licensed firms sharing a family name cannot be told apart by name alone. Attributing one company's record to another is not a mistake worth risking, so this page counts permits and buildings and stops there.
Permits are matched to this contractor by licence number and licence type, in both of DOB's permit systems — the legacy BIS feed, which pads the licence to seven digits, and DOB NOW, which pads it to six. The type matters: licence numbers are reused across trades, so licence 2540 as a General Contractor is a different business from licence 2540 as a Master Plumber.
Buildings are confirmed against the Department of City Planning's PLUTO extract of the tax roll before they are listed. The legacy feed carries no Borough-Block-Lot number, so one is rebuilt from the borough, block and lot it does carry; where DOB NOW publishes a BBL of its own, that is used instead.
Names are reproduced as filed. DOB's roster cuts a business name at 25 characters and the permit feeds carry several spellings of the same company, so the name above is the fullest spelling the city holds, not a tidied one.
Check a Building reports facts about buildings and the entities that own them. It is not a consumer reporting agency, and this is not a tenant-screening service. Nothing here may be used to decide whether to rent to, hire, insure, lend to, or otherwise evaluate an individual person. It is not assembled or maintained for those purposes, it has not been prepared to the standards those decisions require, and it must not be used for them.
Every figure on this page is drawn from New York City's own published records and is reproduced without warranty that it is complete, current or accurate. Records are matched to an owner by name; a company can be recorded under more than one spelling, and two companies can share one. Verify anything you intend to rely on against the agency's own record. If something here is wrong, tell us — there is a correction link on every record in the app.
