Rent Demand Letter in NYC: 14-Day Rule, Contents, and Service

A rent demand letter in NYC is the written notice a landlord must serve before filing a nonpayment eviction case, giving the tenant at least 14 days to pay overdue rent or vacate the apartment.¹ Since 2024 it must also carry a Good Cause Eviction notice. Verbal requests, texts, emails, and handwritten notes under the door do not satisfy the requirement, and a demand served the wrong way will almost always get the case dismissed.

The 14-Day Rule

Before a landlord can file a nonpayment petition in Housing Court, the tenant must receive a written demand allowing at least 14 days to pay everything owed or surrender the apartment.¹ The 14 days run from proper service of the demand, not from the date it was written or signed.

This window cannot be shortened. A lease clause purporting to cut it to 10 days or waive it entirely will not hold up. Judges look at rent demands closely, and a petition filed even a day early is likely to be dismissed.

What the Demand Must Contain

A valid demand needs more than a statement that rent is overdue. It should:

Name every tenant using the full legal name from the lease.
Identify the property by exact address, including apartment or unit number.
Itemize the arrears month by month, showing the specific dollar amount owed for each period. A single lump-sum figure without breakdown is a frequent reason demands get thrown out.
State clearly that the tenant has 14 days to pay or vacate before a court case begins.

Keep the demand limited to rent. In a nonpayment proceeding, only unpaid rent is at issue, so late fees, legal fees, utility charges, and other add-ons cannot be folded into the amount demanded.² Inflating the demand with non-rent charges hands the tenant a defense.

The New York State Unified Court System publishes an official fillable form titled “Written Demand for Past Due Rent with Good Cause Eviction Law Notice” that includes every required field.³ Using it is the safest way to stay compliant.

The Good Cause Eviction Notice

Every rent demand served under RPAPL § 711(2) must now include a notice telling the tenant whether the apartment is covered by New York’s Good Cause Eviction Law, which took effect in 2024. If the unit is exempt, the demand must state which exemption applies.⁴ The same notice has to reappear later in any petition filed with the court.⁵

The law covers market-rate tenants in buildings with 11 or more units, and tenants in smaller buildings where the landlord does not live on-site, provided the rent falls below 245% of the applicable Fair Market Rent set by the federal government.⁶ Apartments already covered by rent stabilization, rent control, or other government affordability restrictions are exempt.

The official court form has checkboxes for each exemption category. Serving a demand without the Good Cause notice risks having the entire proceeding tossed before the merits are ever considered.

How to Serve the Demand

Writing a perfect demand means nothing if service is defective. Delivery must follow the same methods that apply to a notice of petition under RPAPL § 735.⁷ There are three options.

Personal Delivery

Handing the demand directly to the tenant. This is the simplest method and is complete the moment the tenant takes the papers.

Substituted Service

If the tenant cannot be found but someone of suitable age and discretion is present at the apartment, such as a roommate, family member, or employee, the demand can be left with that person. Within one day the landlord must also mail the demand to the tenant twice: once by registered or certified mail and once by regular first-class mail.⁷

Conspicuous Place Service

When no one at all can be found at the apartment after reasonable attempts, the demand may be affixed to a visible part of the door or slid underneath it. The same dual-mailing rule applies: registered or certified mail and regular first-class mail, both sent within one day.

The Affidavit of Service

Whoever delivers the demand should prepare a sworn affidavit describing exactly when, where, and how it was served. That affidavit is the landlord’s proof in court. Without it, a judge has no way to confirm the tenant received the notice, and the case will stall or be dismissed. Many landlords hire a professional process server to handle delivery and produce the documentation.

Extra Notices for Certain Tenants

Some situations require notices beyond the standard demand.

Section 8 voucher tenants. A landlord renting to a tenant with a Housing Choice Voucher must send a copy of any eviction notice to the local public housing authority at the same time it is served on the tenant.⁸ In New York City that generally means the New York City Housing Authority or the administering agency for the voucher. Keep a certified mail receipt as proof. Skipping this step creates a defense for the tenant.

Active-duty service members. Under the federal Servicemembers Civil Relief Act, a landlord cannot evict a service member or their dependents from a residence without a court order when the monthly rent falls below the annually adjusted threshold, currently $10,542.60 for 2026.⁹¹⁰ Most NYC apartments fall under that ceiling. A service member can also ask the court for a stay of up to 90 days, or longer if military service affected their ability to pay. Knowingly evicting a covered service member without a court order is a federal misdemeanor.

Demands sent by an attorney or collection agency. A landlord collecting rent from their own tenants is not a debt collector under the federal Fair Debt Collection Practices Act.¹¹ An attorney or agency sending the demand on the landlord’s behalf is, and the letter may need to include a federal debt validation notice within five days of the initial communication.¹² Skipping that notice exposes both the attorney and the landlord to FDCPA liability. A landlord who uses a fictitious business name suggesting a third party is collecting the debt can also be pulled into FDCPA territory.

Common Defenses That Kill a Defective Demand

Tenants who receive a rent demand have several ways to attack it in court. Landlords should read this list as a checklist of what to avoid.

Improper or missing demand. No written 14-day demand, or one that was defective (wrong tenant name, no itemization, missing Good Cause notice), can dismiss the case.
Non-rent charges included. A demand that mixes in late fees, legal costs, or utility bills goes beyond what a nonpayment proceeding covers.
Rent was paid or tendered. Receipts, canceled checks, or money order stubs defeat the demand. So does proof that the tenant tried to pay and the landlord refused.
Warranty of habitability. Serious conditions such as no heat, mold, or pest infestation can lead the court to reduce the rent owed, sometimes substantially. Photos, inspector’s reports, and written complaints support the claim.
Rent overcharge. For rent-stabilized tenants, anything charged above the legal regulated rent is not collectible through a nonpayment case.

Tenants can also raise counterclaims in the same proceeding. If the landlord owes money for conditions issues or security deposit violations, the court can weigh those against the rent demanded.
