LPC approval for facade work on a landmark building
If the building is an individual landmark or sits in a historic district, the Landmarks Preservation Commission has to approve the work before DOB will issue the permit.
Do I need LPC approval for facade repairs in NYC?
If the building is an individual landmark or in a historic district, yes — LPC approval comes before the DOB permit, not after. It is a separate agency with its own review and its own calendar, and substitute materials are reviewed much more strictly on an individual landmark than in a historic district.
What matters on a real job
LPC first, DOB second
The order is not negotiable and it is where schedules slip.
Two different statuses
An individual landmark and a building inside a historic district are not reviewed the same way.
Substitute materials get scrutiny
Replacing terra cotta or stone with a substitute is a review question, not a means-and-methods question.
