Does Your Building Need an ARCS System in NYC?
Auxiliary Radio Communication Systems (ARCS) aren’t just a “nice to have” anymore—in many NYC buildings, they’re legally required. But figuring out whether your building needs one (or should have had one) isn’t always straightforward.
If you’re an architect, general contractor, or building owner in New York City, this quick guide will help you understand when ARCS is required, what triggers it, and how to take the right next steps to avoid delays and violations.
What Triggers ARCS Requirements in NYC?
The NYC Building Code and FDNY Fire Code now require ARCS under specific conditions, typically for buildings where first responders may lose radio signal during an emergency.
Here’s when you need to take action:
- New Construction High-Rises
- Any new building over 75 feet in height will likely require ARCS installation as part of its FDNY approval and Certificate of Occupancy process.
- Major Alterations or Expansions
- If you’re vertically expanding a structure or undergoing a significant renovation that affects egress paths, walls, or radio propagation, your building may be reclassified—and ARCS may be triggered as part of the project review.
- Plan Examiner or Fire Protection Engineer Requests It
- Even if your building doesn’t fall into the above categories, an FDNY plan examiner or DOB official may still require ARCS after evaluating the building’s layout, construction materials, and impact on radio signals.
- Occupancy Classifications That Require Enhanced Safety
- Hospitals, hotels, schools, and high-occupancy assembly spaces often require ARCS as a condition of fire protection compliance.
“Just because it wasn’t required when the building was built doesn’t mean it won’t be now—especially if you’re filing new plans.”
How to Check If Your Building Requires ARCS
If you’re unsure about your specific situation, here are 3 steps you can take right now:
1. Review Your DOB Filing History
Look for ARCS notations in your building’s permits or recent filings. Some plan examiners include ARCS notes directly in objections or comments.
2. Check the FDNY ARCS Requirement List
The FDNY maintains an internal list of properties and conditions that trigger ARCS. A licensed vendor like IRL Systems can help review this and verify your building’s status.
3. Schedule a Free ARCS Consultation with IRL Systems
We’ll perform a radio coverage evaluation, examine your plans, and let you know if ARCS is likely to be required—before you get hit with an objection or stop-work order.
What Happens If You Ignore an ARCS Requirement?
Delaying or skipping ARCS installation can result in:
- DOB plan objections and project delays
- Inability to secure a Temporary or Final Certificate of Occupancy
- Violations from FDNY or failed site inspections
- Liability exposure in the event of an emergency
If your building is nearing completion or already under construction, it’s far easier to install ARCS now than to retrofit it later.
“Adding ARCS after final inspections costs more and risks opening walls and ceilings that were already finished.”
What If You’re Already Occupied?
In most cases, existing buildings are not required to install ARCS retroactively—unless there’s a significant alteration underway. However, if your building has experienced signal issues during previous FDNY calls, or you’re considering major MEP upgrades, ARCS may become a condition of your next permit approval.
IRL Systems can help evaluate your risk and determine your next steps.
