Final Updates To NYC DOHMH Window Guard Rules Published: Your 2025 Essential Guide
Final Updates To DOHMH Window Guard Rules Published—New York City’s Department of Health and Mental Hygiene (DOHMH) has issued final rules fully replacing Chapter 12 of Title 24. These rules modernize standards to cover both traditional double-hung windows and a wider range of window types and fall-prevention devices. Owners and managers must prepare now so their buildings are ready for the January 1, 2026 effective date.
Why Did DOHMH Change the Rules?
Originally, the rules focused on double-hung windows and “traditional window guards” (TWGs). Over time, New York City buildings adopted many other window types and fall-prevention devices. The revised rules use the broader term “window guard” to include TWGs and newer limiting devices that prevent falls across modern window designs.
Understanding the nyc dohmh window guard rules is essential for all New York City landlords. The nyc dohmh window guard rules have been designed to enhance safety and compliance.
To speed up approvals and keep pace with technology, the final rules also replace the former Window Guard Policy and Acceptance Board with a more streamlined registration program inside DOHMH.
Compliance with the nyc dohmh window guard rules will be enforced starting January 1, 2026, ensuring that all properties meet the safety standards set forth.
New Device Registration Program
The nyc dohmh window guard rules require owners to submit detailed plans to ensure safety across various types of windows.
Understanding the NYC DOHMH Window Guard Rules
Manufacturers and building owners can submit devices directly to DOHMH for evaluation, including technical documentation and professional engineer or architect affidavits. This aims to accelerate approvals, ensure consistent safety standards, and provide clarity on what devices are compliant.
Safety compliance is crucial, and the nyc dohmh window guard rules provide guidelines on how to achieve this.
Understanding the implications of the nyc dohmh window guard rules can help landlords avoid penalties.
What’s New at a Glance
-
- Broader Coverage: “Window guard” now includes both traditional guards and limiting devices for a variety of window types.
- Registration Program: DOHMH will review device submissions (with required documentation) directly.
- Air Conditioner (AC) Regulation: Clear standards for using permanently installed window AC units as compliant window guards in double-hung windows.
Owner compliance with the nyc dohmh window guard rules is essential to maintain safety in residential buildings.
- Balcony/Terrace Windows: Devices must be installed on windows that open onto balconies or terraces above the first/ground floor of multiple dwellings.
- Annual Safety Notices: Outdated language is removed; owners must use updated DOHMH wording and follow new reminder rules.
Adhering to the nyc dohmh window guard rules is not just a legal obligation but a moral one as well.
Annual Safety Notice Mailings
Owners must continue to send annual safety notices to residents using current DOHMH-approved language. If residents don’t respond, owners must inspect units to determine whether window guards are required.
Important: DOHMH will publish updated language (online and via 311). Owners may still use combined safety notice language for window guards and lead paint where provided by DOHMH/HPD.

Understanding the nyc dohmh window guard rules helps in implementing effective safety measures.
The final rules simplify—but maintain—core safety performance standards:
-
- Limit openings to no more than 4½ inches at the bottom/sides of any open sash, or between bars/grids.
Following the nyc dohmh window guard rules is essential for safeguarding the well-being of tenants.
-
- No opening may allow more than an additional ½-inch deflection in a way that would permit a five-inch diameter sphere to pass through.
- Devices must withstand the impact of a 150-pound weight and maintain structural integrity after testing.
Regular updates about the nyc dohmh window guard rules are vital for compliance.
At-a-Glance Device Specification Table
| Requirement | Standard |
|---|---|
| Max opening | ≤ 4½ inches |
| Deflection allowance | ≤ ½ inch; must not allow 5-inch sphere to pass |
| Impact resistance | Withstand 150-pound impact; integrity maintained post-test |
Exception Reminders
Reviewing the nyc dohmh window guard rules helps clarify the responsibilities of property owners.
Owners must install window guards for any unit where they know or reasonably should know a child resides, or where the occupant requests it—including balcony/terrace windows. Key exceptions include:
- Windows opening onto fire escapes and secondary egress windows
- Window openings at or below ground level
- Emergency escape and rescue openings
Review the full rule text for definitions and installation details related to these exceptions.
Air Conditioner Requirements
The rules allow certain permanently installed window AC units in double-hung windows to serve as compliant window guards when all of the following are true:
-
- Secure installation: The AC is securely bolted into the stool/sill with tamper-resistant one-way screws, leaving no opening larger than 4½ inches.
To ensure compliance with the nyc dohmh window guard rules, window installations must be regularly inspected.
- Window stops: Two metal “L”-shaped stops/brackets are installed (one on each side of the bottom sash) to prevent the lower sash from opening more than 4½ inches above the unit.
- Owner inspection: The building owner has inspected and verified the installation meets items (1) and (2).
AC Guard Compliance Quick Check
- AC is permanently secured with tamper-resistant one-way screws
- No gap > 4½″ around or above the unit
- Two L-stops installed; lower sash cannot rise > 4½″
- Owner has documented inspection/approval
