FDNY Approved Window Gates in NYC That Keep the Exit Clear.
A fire escape window is the easiest way into many NYC apartments, and it’s also the way out in a fire. Locking it with the wrong gate, a padlock, or a key-operated latch can trap your family inside, and installing an unapproved gate on that window is prohibited in NYC. Alto Locksmith & Security installs and repairs FDNY approved window gates in NYC that stay locked from outside and open from inside in one easy motion, with no key needed.

Know Which Window Product You Actually Need
People often use these terms interchangeably, but NYC treats them as two separate products with separate rules.
| Aspect | Security Window Gate | Child Safety Window Guard |
|---|---|---|
| Purpose | Keeps intruders out | Keeps children from falling out |
| Who Sets the Rules | FDNY, for fire escape windows | NYC Health Department |
| Where It Goes | Fire escape and ground-floor windows | Every window except fire escape and emergency exit windows |
| How It Opens | Approved fire escape gates open from inside without a key | Fixed in place and never removed by tenants |
| Approval Mark | FDNY approval number on the gate | "HDWG #" stamp on the guard |
| Who Usually Pays | The owner or tenant who wants it | The building owner, when required |
The most important rule connects the two: a child safety window guard must never go on a fire escape window, and any gate on that window has to be FDNY approved.

FDNY Rules for Fire Escape Window Gates
The rules for fire escape windows are strict because that window may be the only way out.

Frequently Asked Questions
Are window gates allowed on fire escape windows in NYC?
Yes, but only FDNY-approved gates that open from inside without a key, a tool, or special effort. Installing any other kind of gate on a fire escape window is prohibited.
How do I know if my window gate is FDNY approved?
An approved gate is stamped or labeled with an FDNY approval number. It should also open from inside in one easy motion with no key.
Can I put a padlock on my fire escape gate?
No, a padlock on a fire escape gate can trap people inside during a fire, and it doesn’t meet FDNY rules. If your gate has one, it should be replaced with an approved keyless gate.
What's the difference between a window gate and a window guard?
A window gate keeps intruders out, and a child safety window guard keeps children from falling. Gates on fire escape windows must be FDNY approved, while guards must be Health Department approved and never go on a fire escape window.
Who has to install child safety window guards?
In buildings with three or more apartments, the owner must install and maintain approved window guards when a child 10 or younger lives in the apartment, or when a tenant asks for them. We install guards for landlords and managers across NYC.
Can a window guard go on my fire escape window?
No, child safety window guards must never be installed on a window that leads to a fire escape or serves as an emergency exit.
Do you repair existing fire escape window gates?
Yes, Alto Locksmith & Security fixes stuck releases, sagging hinges, and loose mounting so the gate opens smoothly. If a gate can’t be repaired or isn’t FDNY approved, we’ll recommend a replacement.
Can I install a removable window gate?
Yes, on windows that aren’t fire escape access or required exits. Removable gates lift out or swing away when you need the full opening. On fire escape windows, only FDNY-approved gates are allowed.
Do I need my landlord's permission to install a window gate?
Many leases require approval before any change to windows, and some buildings have their own rules. Check with your landlord first, and we can install the gate once it’s approved
How long does window gate installation take?
Measuring takes one short visit. Most gates are custom-sized, and installation usually takes about an hour per window once the gate is ready.
