Cell towers that are used by cellular and wireless network to distribute wireless connectivity thru mobile and internet connection are usually placed on the highest point of the building to maximize signals and more often than not, they are considered permanent attachments to the building.
These towers are usually placed on monopoles in open fields and placed on building ramparts, more so in highly urbanized areas. Installation of cell towers can include various related equipment and these are placed within metal cabinets that are then supported by raised metal platforms usually placed on the roof.
Cell towers are usually renovation works classified as Alteration Type 2 or 3 (OT-ANT). Here are a few considerations.
New York City Building Code
The 2008 Building Code (BC) prescribes standards for location, access, construction, loads and electrical grounding.
New York City Zoning Resolution
The Zoning Resolution is not applicable to cellular antenna towers; they are considered to be a utility accessory to a building.
New York City Fire Code
Fire Department access clearances on the roof and restrictions on rooftop obstructions are outlined in the Fire Code (FC).
Monopole Installations
Monopole installations must comply with use, height and setback regulations and be approved by the Board of Standards and Appeals (BSA).
Other Agency Approvals
You might need to get approval from other city agencies depending on where the building is located,
- NYC Art Commission: Approval required for City-owned property
- Board of Standards and Appeals: Approval required for monopoles
- Landmarks Preservation Commission: Approval if in Landmark District
This publication is just an overview of the requirements for this type of work. There may be additional, applicable Zoning Resolution, Construction Code, Multiple Dwelling Law or Energy Code requirements.
