The New York City Department of Housing Preservation and Development (HPD) requires all residential buildings in the city to display a serial number sign in a visible location at the entrance to the building. This requirement is outlined in the New York City Administrative Code Section 27-2107, which mandates that the serial number sign must be provided and installed by the building owner or landlord.


The serial number sign serves as a unique identifier for the building and is used by various city agencies to keep track of important information, such as ownership, occupancy, and violations. The sign must be made of durable and weather-resistant materials, such as metal.


According to HPD guidelines, the serial number sign must include the following information:


ü  The building's assigned serial number, which is provided by the HPD.

ü  The address of the building, including the street number and name.

ü  The name of superintendent and contact

The serial number sign must be installed in a visibl preferably near the main entrance or in a location that is easily visible from the street. The sign should be securely mounted to the building, using appropriate hardware and installation methods to ensure that it is not easily removed or damaged.


Failure to comply with the requirements of the HPD serial number sign can result in fines and penalties, as well as potential legal and financial liabilities. Therefore, it is important for building owners and landlords to ensure that their buildings are in compliance with the regulations set forth by the HPD and other city agencies.
