A deep-dive guide to the 11 mandatory NYC lease disclosures landlords must attach to every residential lease, what each one requires, who it applies to, and what happens when it is missing.
Most NYC lease disputes do not start with rent. They start with a missing piece of paper. A disclosure that was supposed to be attached at signing, that the landlord assumed was optional, or that the prior lease packet never included. By the time it surfaces, the tenancy is already in trouble and the landlord's file is thinner than it should be.
This guide walks through the 11 mandatory NYC lease disclosures that should sit inside a residential lease package today. Some are federal, some are state, and some are New York City specific. Each one exists for a reason, and each one has a real consequence when it is skipped.
1. Lead-based paint disclosure (federal)
Required for any residential building built before 1978. The landlord must give the tenant the EPA pamphlet "Protect Your Family From Lead in Your Home," disclose any known lead-based paint or hazards, and have the tenant sign an acknowledgment. The disclosure must be attached to the lease itself.
Missing this disclosure is one of the few lease defects that carries direct federal penalties. It also undermines any later defense in a habitability or personal injury claim involving a child.
2. Window guard notice (NYC)
Every NYC residential lease must include the window guard rider. The rider tells the tenant that the landlord is required to install window guards if a child ten years old or younger lives in the apartment, or on request. The tenant indicates whether a child resides there.
Skipping this is a classic small-landlord mistake. The form looks generic, so it gets dropped. But the city treats it as part of the lease, and inspectors do check for it.
3. Bedbug disclosure (NYC and NY State)
Landlords must provide the annual bedbug disclosure form, which discloses any bedbug infestation history in the building and the specific unit for the prior year. It must be given to every new tenant at lease signing and to existing tenants annually.
A missing or inaccurate bedbug disclosure is more than a technical violation. It becomes evidence in any later infestation dispute, and it gives a tenant an easy argument that they were not informed.
4. Smoke detector and carbon monoxide detector notice
NYC and New York State require working smoke and CO detectors in residential units, and the lease should include the notice describing the tenant's responsibility to maintain the devices and report problems. The landlord is responsible for installation and initial operation; the tenant typically handles batteries and reporting.
If a fire or CO incident occurs, the absence of this notice in the signed lease becomes a problem quickly. Insurance carriers and plaintiffs' attorneys both look for it.
5. Sprinkler system disclosure (NY State)
For any residential lease, the landlord must disclose in conspicuous bold print whether the unit has a maintained and operative sprinkler system, and if so, the date of last maintenance and inspection. This applies regardless of whether a sprinkler is required by code.
It is short. It is easy. It is also one of the most commonly missed disclosures in small-landlord lease packets because owners assume it only applies to commercial space. It does not.
6. Stove knob cover notice (NYC Local Law 117)
NYC landlords must provide stove knob covers on request when a child under six lives in the apartment, and the lease must include a notice informing the tenant of that right. This is a relatively new requirement, and many older lease templates do not include it.
If your lease form was last updated more than a couple of years ago, this is almost certainly missing. Update the packet.
7. Gas leak / gas safety notice
NYC landlords must provide tenants with the city's gas leak safety information at lease signing and annually thereafter. The notice explains how to recognize a gas leak and how to report it. The lease should reflect that this information has been delivered.
The reason this matters is regulatory. Con Edison incidents and DOB investigations frequently ask whether tenants were informed of gas safety procedures. The lease file is where that proof lives.
8. Indoor allergen hazards notice (NYC Local Law 55)
Landlords of multiple dwellings must annually provide the indoor allergen hazards notice and inquire whether anyone in the household has asthma or allergies. The notice and inquiry must be part of the lease package for new tenants and renewed annually.
This is enforced. Health Department inspections cite landlords for missing Local Law 55 disclosures, and the absence becomes part of the file in any mold or asthma-related habitability claim.
9. Rent stabilization rider (when applicable)
If the unit is rent stabilized, the lease must include the DHCR rent stabilization rider, which explains the tenant's rights, the legal regulated rent, and the basis for the rent being charged. Failing to attach the rider is not a minor issue; it can affect rent overcharge calculations and the landlord's ability to collect increases.
Even owners who believe their building is fully market-rate should confirm regulatory status before signing. Mistaken classification is a recurring source of overcharge exposure.
10. Security deposit receipt and bank disclosure
New York law requires the landlord to disclose where the security deposit is being held, including the name and address of the banking institution and the account information, and to provide a written receipt. Under the Housing Stability and Tenant Protection Act, deposits are also capped at one month's rent for most units.
A vague "your deposit will be held in trust" line is not enough. The lease or an attached receipt should name the institution. Missing this becomes a problem when the deposit is later contested.
11. Good Cause Eviction notice (when applicable)
For covered units under New York's Good Cause Eviction law, landlords must provide a notice at lease signing and on renewals stating whether the unit is covered, and if not, the specific exemption that applies. The notice must use the prescribed language.
This is the newest item on the list and the one most likely to be missing from older lease templates. If you have not updated your lease package since Good Cause took effect, your file is incomplete on every signing.
What happens when a disclosure is missing
A single missing disclosure rarely voids a lease outright. But it does three things that hurt the landlord. First, it weakens enforcement. A tenant's attorney will use any missing required notice to argue that the landlord did not meet baseline obligations, which colors the rest of the case. Second, it creates direct exposure. Some disclosures, like lead paint and rent stabilization riders, carry their own penalties or rent consequences. Third, it makes the file look careless, and judges notice.
The cumulative effect is what matters. A lease missing one disclosure is a problem. A lease missing three or four reads like a landlord who did not take the tenancy seriously, and that perception affects discretionary decisions throughout the case.
How to make sure every disclosure is in the file
The reliable path is to stop assembling lease packets manually. A purpose-built NYC lease workflow attaches the correct disclosures based on the property facts, captures tenant acknowledgments inside the same signed document, and preserves the entire package as executed. That is the difference between hoping the disclosures are there and being able to prove it.
Small landlords often underestimate how much of their risk lives in document assembly. Rent collection systems get attention. Lease compliance does not. But when a tenancy goes to housing court, the file is the case. Every missing disclosure is a gap a tenant-side attorney can walk through.
The bottom line
These 11 disclosures are not optional and not interchangeable. They are the floor of what an NYC residential lease should include before the tenant signs. Landlords who treat the disclosure package as carefully as the rent and term are the ones whose files hold up. The work is small. The downside of skipping it is not.
