DOB Issues Standards for Cellular Antenna Installations

In coordination with the City's effort to further deploy 5G cellular antenna technology designed to provide New Yorkers with expanded high-speed Internet, the Department has issued Technical Bulletin 2021-011 to clarify antenna installation allowances in all zoning districts as outlined in the Technical Policy Procedure Notice 5 of 1998.

Antennas and related equipment may be placed on select building structures such as a roof, chimney and smokestack or water tank. Depending on placement, the antenna's height, square footage allowed (including related equipment) and how they are positioned must comply with the Technical Bulletin.

The submission of plans should also document placement of existing antennas and related equipment as well as proposed installations. To read the Highlights or full Technical Bulletin, visit DOB online.
