New York Lease Renewal Offer Requirements & Timing — Compliance Guide (2026)

What Is RSC §2523.5(a) and Why It Matters to Your Rental Business

If you own rental property in New York and let a lease expire without proper renewal notice, you may have just handed your tenant leverage you didn't know you were giving away. Renewal lease offers in New York are governed by a strict statutory framework under Rent Stabilization Code §2523.5(a), which mandates when you must offer a renewal and what that offer must contain.

For self-managing landlords with 2–75 units, this statute is foundational. It directly affects your ability to increase rents, modify lease terms, and maintain control over your portfolio. Violating §2523.5(a) doesn't result in a gentle warning—it can trigger:

• Tenant claims for wrongful non-renewal
• Lease continuation under existing terms (blocking your intended increases)
• Attorney fees and statutory damages awards
• Housing Court litigation that costs thousands to defend

This guide walks through the exact requirements, timelines, and compliance steps you need to execute renewal notices correctly—before a tenant's attorney does it for you.

The 90-Day Renewal Notice Requirement: What the Statute Actually Says

RSC §2523.5(a) states that a renewal lease must be offered to the tenant in writing at least 90 days before the expiration of the current lease. This is not discretionary. It is not a "best practice." It is a legal mandate.

Let's break down what "at least 90 days" means in real-world terms:

• If your lease expires on December 31, 2026, the renewal offer must be received by the tenant no later than October 3, 2026 (90 days prior)
• Counting begins from the date of delivery to the tenant, not the date you draft the letter
• If you mail the notice via certified mail on October 3, and it arrives on October 5, that still satisfies the deadline because the statute requires delivery within 90 days
• If you wait until October 4 to send it, you've missed the deadline, and the tenant may have grounds to refuse renewal

Practical Compliance Action: Calendar Your Deadlines Now

For each lease in your portfolio, calculate the 90-day renewal deadline and add it to your calendar at least 100 days before lease expiration. Here's why the extra 10 days matters: it gives you time to draft the renewal offer, have it reviewed, and ensure proper delivery without last-minute scrambling.

Example timeline:

• Day 100: Calendar reminder to begin renewal notice preparation
• Day 95: Finalize rent amount, lease terms, and draft renewal letter
• Day 91: Mail or personally deliver renewal notice
• Day 0: Lease expiration date

If you manage multiple properties, this manual tracking becomes error-prone. LeaseBase's lease operations module flags renewal deadlines automatically and logs proof of delivery—eliminating the guesswork and protecting you in Housing Court disputes.

What Must Be Included in a Compliant Renewal Offer

Simply sending a letter that says "We'd like to renew your lease" is not enough. The statute and case law interpreting it require that the renewal offer specify certain material terms. If your renewal notice is vague or incomplete, a tenant can challenge it as invalid, and you lose the ability to enforce the new terms.

Required Elements of a Renewal Notice Under §2523.5

Your renewal lease offer must state:

• The new rent amount — specific dollar figure per month; a percentage increase is acceptable if it clearly translates to a final amount
• The lease term (duration) — typically 1 or 2 years; must be clearly stated
• All material lease terms that differ from the current lease — if you're changing pet policy, parking, maintenance responsibilities, or utility provisions, these must be explicitly noted in the renewal offer
• The effective date of the renewal — when the new lease begins (usually the day after current lease expires)
• The deadline for tenant acceptance — you may specify a reasonable deadline (e.g., "Tenant must accept by [date]"), though this must not be so short as to be deemed oppressive; 30 days is standard

What happens if you omit a required element? Courts have ruled that incomplete renewal notices may be invalid. In one Housing Court decision, a landlord's renewal offer that failed to specify lease duration was deemed ineffective because the tenant could not form a binding agreement without that term. The lease was deemed to have continued under existing terms, and the landlord's intended rent increase never took effect.

Changes to Lease Terms: Full Disclosure Required

If your renewal offer includes lease terms different from the current lease, you must disclose them clearly. Do not bury changes in dense legal language. Examples of material changes include:

• Shift from landlord-paid utilities to tenant-paid utilities
• Addition of a new pet deposit or pet rent
• Changes to maintenance responsibilities (e.g., tenant now responsible for yard maintenance)
• Addition or modification of renewal fees
• Modification of lease termination or break clauses

For each material change, use a format like: "CHANGE: Current lease includes [old term]. Renewal lease will [new term]."

Delivery Methods That Actually Satisfy the Law

You must prove you delivered the renewal notice 90 days before expiration. The method of delivery matters because it determines whether you have legal evidence of timely service.

Compliant Delivery Methods

Delivery Method	Proof of Service	Timing Rule	Compliance Notes
Personal service to tenant	Signed receipt or affidavit of service	Date of personal hand-off to tenant	Strongest evidence; no ambiguity about receipt
Certified mail with return receipt	USPS return receipt showing signature date	Date package was signed for by recipient	Widely accepted; allows for standard mail delivery delays (1-3 days)
Regular certified mail (no signature required)	USPS tracking showing delivery	Date of USPS delivery attempt/receipt	Acceptable but weaker than return receipt; tenant can claim non-receipt
Authorized agent (property manager, attorney)	Agent's affidavit of service + written authorization	Date agent served tenant	Must have written power of attorney; oral authorization insufficient
Email (only if lease permits)	Email delivery receipt + lease clause allowing service by email	Date email sent, if lease permits; otherwise not compliant	RSC §2523.5(a) does not explicitly authorize email; use only if lease allows and you have tenant's written consent to email service

Critical warning: Email service alone does not satisfy §2523.5(a) unless your lease explicitly permits service by email and the tenant has acknowledged this in writing. Many landlords have lost Housing Court cases by relying solely on email without backup certified mail.

Best practice: Use certified mail with return receipt AND follow up with a copy by regular mail. This creates a paper trail that is nearly impossible for a tenant to dispute.

Rent Increases and RGB Compliance for Stabilized Units

If the tenant occupies a rent-stabilized apartment, your renewal notice requirements are more complex. The Rent Guidelines Board (RGB) sets allowable rent increases each June, and your renewal offer must comply with those percentages.

How RGB Orders Affect Your Renewal Notice

Each June, the RGB votes on the allowable rent increase for the coming lease year. As of 2026, the RGB issues orders covering lease renewals from October 1, 2026 through September 30, 2027. Your renewal notice must reference the correct RGB order.

Example: If you're renewing a lease expiring on December 31, 2026, the tenant qualifies under the RGB order effective October 1, 2026. You must increase rent by no more than the 1-year renewal percentage set by that order. If the RGB order permits a 3% increase for 1-year renewals, and you propose a 5% increase, the renewal notice is invalid, and you cannot enforce the higher rent.

Where to Find Current RGB Orders

Visit www.nyc.gov/rent-guidelines-board for current orders. Download and retain copies of all applicable RGB orders before drafting renewal notices. The RGB publishes orders by effective date and lease term (1-year vs. 2-year). You must offer the tenant the renewal option they choose (1 or 2 years), and you must use the RGB percentage for that term.

What Happens When You Miss the 90-Day Deadline

Missing the 90-day renewal notice deadline has serious consequences. It's not a minor infraction that you can remediate by sending a late notice. Under New York case law, a landlord who fails to timely offer a renewal lease may be estopped (legally prevented) from refusing to renew.

Possible Outcomes of Late or Missing Renewal Notice

• Automatic lease continuation: The lease continues under all existing terms (including rent) until you provide proper notice. This can persist for months or years.
• Tenant right to refuse renewal: Some courts have held that a tenant who did not receive timely notice has the right to refuse renewal and force the landlord to begin eviction proceedings.
• Damages and attorney fees: The tenant can sue for wrongful non-renewal, and if the tenant prevails, you pay their attorney fees. These fees regularly exceed $2,000–$5,000 in Housing Court cases.
• Inability to increase rent: If the lease continues under existing terms because of your late notice, you cannot increase the rent until the lease formally renews or you issue a new notice (subject to the 90-day requirement).

Case example: In a 2024 Housing Court decision, a landlord served a renewal notice 45 days before lease expiration. The tenant's attorney argued the notice was untimely under §2523.5(a). The court found the renewal notice invalid and deemed the lease continued under existing terms. The tenant remained in the apartment at the old rent for an additional 18 months until the landlord restarted the renewal process.

Step-by-Step Compliance Checklist for Renewal Notices

Use this checklist for every lease renewal to ensure you meet §2523.5(a) requirements:

Pre-Notice Preparation (100 Days Before Expiration)

• ☐ Review current lease and identify all material terms
• ☐ Determine if unit is rent-stabilized; if yes, download current RGB order
• ☐ Calculate new rent amount (including any allowable increase under RGB rules)
• ☐ List any lease term changes (utilities, pets, parking, maintenance responsibilities)
• ☐ Verify tenant's current contact address (use the address from the current lease or verified recent mail)
• ☐ Confirm authorized agent's status if using property manager or attorney to serve notice

Notice Preparation (95 Days Before Expiration)

• ☐ Draft renewal notice letter on company letterhead with your name, address, and contact information
• ☐ State the new rent amount clearly (e.g., "Renewal rent: $1,500 per month" — not "increase of 3%")
• ☐ State lease term duration (e.g., "12-month lease term commencing January 1, 2027")
• ☐ Specify effective date of renewal (usually day after current lease expiration)
• ☐ List all material lease term changes in bold, with before-and-after language
• ☐ If stabilized unit, cite RGB order number and date (e.g., "in accordance with Rent Guidelines Board Order #56, effective October 1, 2026")
• ☐ Include acceptance deadline (recommend 30 days from notice date)
• ☐ Include your signature and date
• ☐ Do not make threats or pressure statements (e.g., "If you don't accept by this date, we will pursue eviction")

Service (91 Days Before Expiration)

• ☐ Prepare renewal notice in duplicate or triplicate (one for tenant, one for your records, one for certified mail)
• ☐ If using certified mail: address envelope, request return receipt, and mail
• ☐ If using personal service: arrange with authorized agent; obtain signed receipt from tenant
• ☐ Save copies of all notices and proof of service (certified mail receipt, agent affidavit, signed receipt)
• ☐ Log the service date and method in your lease tracking system
• ☐ Do not rely on email unless lease explicitly permits it; send hard copy backup

Post-Service (Throughout Acceptance Period)

• ☐ Respond to tenant inquiries about renewal terms within 3 business days
• ☐ Do not modify renewal terms after notice is served unless tenant requests and you agree in writing
• ☐ Track tenant's acceptance or non-acceptance by the stated deadline
• ☐ If tenant accepts, prepare signed renewal lease within 5 business days
• ☐ If tenant does not respond by deadline, send follow-up letter confirming offer remains open or stating when offer expires
• ☐ Retain all signed renewal leases in your permanent lease file

Common Mistakes That Create Legal Liability

Mistake #1: Serving Notice Less Than 90 Days Before Expiration

What happens: The notice is invalid under §2523.5(a). The lease may continue under existing terms, and the tenant can refuse the renewal.

How to avoid: Calendar the 90-day deadline immediately upon lease signing. Check it quarterly. Add a 100-day reminder to your system.

Mistake #2: Omitting Required Lease Terms or Leaving Them Vague

Example: Sending a renewal notice that says "Rent will increase" without stating the new amount. Or saying "Standard lease terms apply" without itemizing changes.

What happens: Courts have invalidated vague renewal notices as lacking material terms. The tenant can claim they didn't have enough information to accept.

How to avoid: Include exact rent amounts, lease duration in months/years, effective dates, and a clear before-and-after statement of any changed terms.

Mistake #3: Using Email Without Lease Authorization

What happens: The tenant claims non-receipt. The email bounces or lands in spam. You have no proof of service. The renewal notice is deemed invalid.

How to avoid: Use certified mail with return receipt as your primary service method. Email is permissible only if the lease explicitly authorizes email service and you have the tenant's consent in writing.

Mistake #4: Increasing Rent Above RGB Limits for Stabilized Units

What happens: The renewal notice proposes a rent increase that violates the RGB order. The notice is invalid. The lease continues under existing (lower) rent. You cannot enforce the increase without starting the renewal process over.

How to avoid: Always check the RGB order for the lease expiration date. Print and file the RGB order with each renewal notice. Use the official RGB percentage, not a percentage you calculate yourself.

Mistake #5: Failing to Keep Proof of Service

What happens: The tenant claims they never received the renewal notice. You have no certified mail receipt, no agent affidavit, no signed receipt. In Housing Court, the judge may rule you failed to serve notice timely.

How to avoid: Keep a "service file" for each lease. File every certified mail receipt, return receipt, agent affidavit, and any signed proof of service. Photograph these documents and keep digital copies.

How to Document Compliance (Proof of Timely Service)

Housing Court judges make decisions based on evidence. If a tenant disputes whether they received the renewal notice, your proof of service is everything.

Gold Standard Documentation

• Certified mail with return receipt signed by tenant or occupant: Keep the USPS green card showing the signature date and recipient name. This is nearly bulletproof.
• Affidavit of personal service by authorized agent: Have your property manager or attorney sign an affidavit stating the date, time, location, and method of personal service (e.g., "On October 1, 2026, at 2:15 PM, I personally delivered the renewal notice to John Doe at 123 Main Street, Apt. 4B"). Obtain the tenant's or occupant's signature on the affidavit if possible.
• Combination method: Mail by certified mail AND have a backup affidavit stating the date you mailed it. If there's any dispute, you have multiple forms of proof.

Documentation File Structure

Create a folder for each lease renewal that includes:

• Copy of current lease
• Draft renewal notice (with date drafted)
• Executed renewal notice sent to tenant
• Certified mail receipt (if applicable)
• USPS return receipt signed by tenant (if applicable)
• Agent affidavit of service (if applicable)
• Tenant acceptance or non-acceptance letter
• Signed renewal lease (if accepted)
• Log entry with service date, method, and any follow-up

This file becomes your defense in Housing Court. Without it, you are relying on your memory, which courts do not trust.

Special Situations: Non-Stabilized and Market-Rate Renewals

While RSC §2523.5(a) is technically a stabilized-housing statute, the 90-day notice requirement and formal renewal process have become standard practice for all New York residential leases. Even if your tenant is not stabilized, serving a professional, timely renewal notice protects you and clarifies expectations.

Non-Stabilized Units

For market-rate apartments, there is no RGB limit on your rent increase, but you still must serve renewal notice at least 90 days before expiration. Failure to do so may trigger lease continuation under existing terms (the court will imply a renewal), preventing you from imposing the increase.

Units with Short-Term Leases

If a tenant is on a month-to-month lease (after an initial term expired), New York law requires you to provide 30 days' notice to terminate or change terms. This is different from the 90-day renewal requirement, which applies when you're offering a new term. If a month-to-month tenant has been in the unit for more than one year, they may have protections against sudden rent increases or eviction without cause.

Practical Tools: Use Lease Management Software to Avoid Errors

The biggest compliance failure we see in self-managed portfolios is human error in tracking renewal deadlines. A landlord manages 5 or 10 units, and one renewal notice gets lost in the shuffle. Months pass. The deadline has expired.

LeaseBase's lease operations platform eliminates this risk by automatically flagging renewal deadlines 100 days before expiration. The system logs the renewal notice and proof of service, and generates compliance reports showing which leases are renewed, pending, or overdue.

The compliance engine also audits renewal notices against New York statutes and RGB orders, catching errors like missing terms or rent amounts that exceed allowable increases before you serve the notice.

Frequently Asked Questions

Q: Can I extend a lease without serving a renewal notice?

A: No. If you and the tenant agree to extend the current lease (rather than replace it with a new lease), you still must follow the renewal notice procedures under §2523.5(a) if the extension is for a new lease term. An "extension" that merely continues the current lease indefinitely without a new term is different and does not trigger the renewal requirement, but this is a murky area. Best practice is to always treat any renewal period as a new lease requiring formal notice.

Q: What if the tenant moves out before the renewal notice deadline?

A: You do not need to serve a renewal notice if the tenant has given you notice of their intention to vacate or has actually moved out. However, if the tenant provides notice late (e.g., on day 89 before expiration), you are no longer obligated to serve renewal notice, but you should acknowledge their move-out in writing and confirm the final rent payment and security deposit return.

Q: If I serve renewal notice by certified mail and the tenant refuses delivery, is the notice still valid?

A: Probably yes, if the USPS attempted delivery. The return receipt will show the carrier's attempt, and that is evidence of timely service. However, some courts have held that a tenant who intentionally avoids delivery can dispute the renewal notice. To protect yourself, follow up with a second copy by regular mail if certified delivery is refused.

Q: Can I propose a rent increase higher than the RGB allows?

A: No, for stabilized units. If the tenant occupies a rent-stabilized apartment, the renewal notice must comply with the applicable RGB order. Proposing an increase above the RGB percentage voids the notice. For non-stabilized units, you can propose any rent increase, but you should still follow the 90-day notice requirement.

Q: What should I do if the tenant does not accept or reject the renewal by my stated deadline?

A: Send a follow-up letter restating your renewal offer and asking the tenant to confirm acceptance or non-acceptance within 10 days. If the tenant still does not respond, you have a few options: (1) assume acceptance and send a final signed lease, (2) declare the offer expired and begin eviction proceedings for non-renewal, or (3) wait for the lease to expire and continue month-to-month. Consult with an attorney before pursuing eviction, as courts may find that silence implies acceptance of renewal.

Q: Do I need to renew the lease, or can I simply let it expire and offer a new lease after the expiration date?

A: Legally, you are not required to renew the lease; you can allow it to expire and refuse to renew, forcing the tenant to vacate (though you must follow proper non-renewal and eviction procedures). However, refusing to renew without legal cause in New York may trigger retaliation claims if the tenant was involved in organizing, filing complaints, or requesting repairs. The safest approach is to renew the lease if the tenant has been a paying resident, unless there is documented cause for non-renewal (e.g., lease violations).
