  • $100 per street address*, certified check (bank only) or money order (bank or post office only), made payable to NYC Dept. of Finance

An example of a vanity address would be 11 Penn Plaza, previously known as 393 7th Avenue.

Structuring the email

Subject line:

  • Include Block and Lot numbers in the subject line.
  • To avoid confusion, do not include any previously assigned or old address numbers that are not the numbers you are requesting in the current application.
  • If you have a preference for address numbers, include the full preferred address/addresses in the subject line. Addresses listed in the subject line are not guaranteed to be assigned, however, this gives us a better idea of your preferred address number. If you do not have one, please list the block and lot number.Sample subject line: “B: 3108 L: 1, Developer name, Owner name, 2046 Mapes Ave BX.”

Body:

  • Please use a single email thread for each new application. Avoid creating multiple correspondence thread for a single case. Additionally, create a separate email thread when sending in each new address application (pertaining to a new Block and Lot Number).
  • If more than one address is being requested for the same lot, you may use a single email thread as well as a single application fee of $100.
  • If more than one address is being requested for the same block and different lots, pertaining to the same project or development, you may use a single thread for correspondence. However, a separate application fee of $100 will be required for each new address on a separate lot.
  • Include in brief a description of the case in the email. This may include any relevant details such as previously assigned addresses, or to state a preference for a certain address number or range. Additionally, if a suffix is required such as “2046 A” or “2046 GAR” please include this information. Make sure these details are included in the correspondence containing the address package as attachments. (During this time, we are not accepting any physical applications.)
  • Clearly state the number of addresses you are requesting for each new application, and indicate these on the corresponding site diagram on the form PD1 using red arrows for each entrance.

The address Package (included as attachments in the email):

  1. Topographic Address Application, available for download on the “Topography” tab of the Bronx Borough President’s office website.
  2. Form PD1, available for download on the Department of Buildings website.
