When NYC landlords must provide window guard notices, the annual delivery rule, and how this HPD requirement protects children under ten years old.
The NYC window guard notice is a local requirement that many small landlords have never heard of until a housing court case brings it up. It is specific to New York City, administered by the Department of Housing Preservation and Development, and it applies to nearly every residential rental unit where a child under ten years old resides or will reside.
What the law requires
Under NYC Administrative Code, landlords must install window guards in any unit where a child under ten lives, and they must provide an annual written notice to every tenant informing them of their right to request window guards. The notice must be delivered between January 1 and January 16 of each year, regardless of whether children currently live in the unit.
The notice must state that the tenant has the right to request window guards, that the landlord must install them upon request, and that the tenant may request them even if no child currently lives in the unit but a child will be living there or regularly visiting.
The January delivery window
The January 1–16 delivery window is strict. A notice sent in February does not satisfy the annual requirement. For landlords managing multiple units, this means a concentrated compliance period at the beginning of every year — a period that is easy to miss if nothing in the workflow prompts it.
The notice can be delivered by first-class mail, hand delivery, or email if the tenant has consented to electronic notice. The method must produce a record of delivery, and the landlord should preserve proof that the notice was sent within the required window.
Who is covered
The requirement applies to all residential rental units in buildings with three or more units, and to one- and two-family dwellings that are rented. It does not apply to owner-occupied one-family homes or to certain cooperative and condominium units where the owner occupies the unit.
For small landlords with multifamily walkups in Brooklyn, Queens, or the Bronx, the safe assumption is that the requirement applies to every unit they rent.
What happens if a tenant requests window guards
If a tenant requests window guards, the landlord must install them in all windows except those that lead to fire escapes or that are required to be operable for egress. The installation must meet HPD specifications, and the landlord cannot charge the tenant for the installation or maintenance of the guards.
A tenant may request window guards at any time, not just in January. The landlord must comply within a reasonable period — generally interpreted as 30 days or less. Failure to install requested guards can result in HPD violations, civil penalties, and tenant-initiated repairs with rent abatement.
Common mistakes
The most common mistake is treating window guards as an optional amenity rather than a mandatory safety device. Some landlords believe that if no child currently lives in the unit, the requirement does not apply. This is incorrect. The annual notice must be delivered to every tenant every January, and the tenant has the right to request guards at any point during the tenancy.
Another common mistake is using a generic notice that does not match the HPD-required language. The notice must contain specific statements about the tenant's rights. A homemade letter that says "let me know if you want window guards" is not sufficient.
Record keeping
The landlord should preserve a copy of the annual notice and proof of delivery for every unit, every year. In a dispute, the tenant may claim they were never notified of their rights. Without proof of delivery, the landlord cannot rebut that claim.
The record should be stored with the lease file for that unit. When the annual notice is delivered, it should be added to the existing lease package so that the full compliance history is retrievable as a single file.
Why this matters in housing court
Window guard violations surface in housing court in two ways. First, a tenant may file a complaint with HPD, which leads to an inspection and violations. Second, a tenant may raise the missing guards as a defense in a non-payment or holdover proceeding, arguing that the unit is not habitable or that the landlord has failed to maintain it.
In either case, the landlord's position is stronger if the annual notice was delivered properly and the guards were installed promptly upon request. The landlord's position is weaker if the notice was skipped, the request was ignored, or the installation was delayed.
The practical workflow
A reliable workflow for window guard compliance looks like this. In December, prepare the notices for every unit. On January 2, send them through a method that produces proof of delivery. Preserve the delivery confirmations. When a tenant requests guards, document the request, schedule the installation, and preserve the installation record.
A lease platform built for NYC should prompt the annual notice delivery automatically, generate the HPD-compliant notice language, and preserve the delivery record in the lease file. If the platform does not handle this, the landlord must build the reminder and the record-keeping into their own calendar — and must not miss the January window.
