Key Takeaways
- ETPA applies only to buildings built before 1974 — Westchester's Rent Stabilization Code covers units in covered buildings; non-compliance penalties start at $500 per violation and can exceed $5,000 per infraction
- Rent increases are limited to 0–1.5% — The Westchester Rent Guidelines Board sets annual allowable increases; exceeding the Board's order is illegal and grounds for tenant complaint to the Department of Housing Preservation and Development (DHPD)
- Rent stabilization is building-specific, not universal — Your Westchester property is covered only if it was built before January 1, 1974, AND is in a municipality that adopted RSC coverage
- Lease renewal notices must follow strict timelines — Failure to serve proper notice 90–150 days before lease expiration can result in automatic lease renewal at current rent plus allowable increase, and tenant claims for damages
- DHPD enforcement has increased audits in Westchester — Landlords found in violation face back rent orders, treble damages (3x overcharges), and attorney fee liability; violations are tracked in tenant complaint databases
- You must register covered units annually — Non-registration forfeits your right to collect rent and bars eviction for non-payment; registration deadline is typically April 30 each year
Understanding Westchester's Rent Stabilization Code vs. NYC's Rules
New York landlords often assume rent stabilization is a statewide or universal rule. It's not. Westchester County's Rent Stabilization Code (RSC) operates independently of New York City's rent control regime, and the rules differ significantly.
The key distinction: Westchester's RSC protects tenants in buildings constructed before January 1, 1974, but only in municipalities that have adopted the RSC ordinance. Not all Westchester towns have adopted it. This means a landlord in Yonkers operates under different rules than one in New Rochelle or Mount Vernon, even though both are in Westchester County.
The Rent Stabilization Code's authority derives from the New York Rent Stabilization Law (ETPA — Emergency Tenant Protection Act). Under the ETPA, local municipalities in Westchester are permitted to establish their own rent stabilization ordinances. Some have; others have not. Your first compliance step: determine whether your municipality adopted RSC.
Which Westchester Towns Have Adopted Rent Stabilization?
As of October 2026, the following municipalities have adopted rent stabilization ordinances covering pre-1974 buildings:
- Yonkers — Covers buildings with 3+ units built before 1974
- New Rochelle — Covers buildings with 2+ units built before 1974
- Mount Vernon — Covers buildings with 2+ units built before 1974
- Port Chester — Limited coverage; verify current ordinance
- Ossining — Limited coverage; verify with Town of Ossining Planning Department
- Pelham — Covers buildings built before 1974
Other Westchester towns (Westchester County itself, Scarsdale, Bronxville, Tarrytown, and others) do NOT have rent stabilization ordinances. In those areas, rent can be increased to market rates at lease renewal, subject only to general landlord-tenant law prohibitions on lease termination for retaliatory reasons.
Action item: Contact your municipality's Planning or Housing Department to confirm whether your building is covered. Many landlords discover non-compliance years later when a tenant files a complaint. Do not assume your town has RSC coverage.
ETPA Coverage: Buildings Built Before 1974
The Emergency Tenant Protection Act (ETPA) is the state-level authority that permits Westchester municipalities to adopt rent stabilization. Under ETPA, a building is covered if:
- It was constructed before January 1, 1974
- It has 2 or more residential units (this varies by municipality; some require 3+ units)
- It is located in a municipality that has adopted a rent stabilization ordinance
ETPA exemptions are narrow. Buildings that do NOT qualify for coverage include:
- Buildings constructed on or after January 1, 1974
- Owner-occupied buildings with 1–2 units where the owner occupies one unit
- Buildings covered under New York City's rent stabilization (separate jurisdiction)
- Hotels, dormitories, and transient housing
A common error: landlords assume that because they own only a few units, they are exempt. This is false. If your Yonkers building has 3 units and was built in 1970, and Yonkers has adopted RSC, your building is covered regardless of size. ETPA coverage is determined by construction date and municipal ordinance, not by landlord size or portfolio.
Checking Your Building's Construction Date
Westchester County records are maintained by the County Assessor's Office (Westchester County Department of Assessment). You can verify your building's construction year by:
- Visiting the Westchester County Assessor's website and searching your parcel ID or address
- Requesting a certified assessment record from the Assessor's Office
- Reviewing your property's deed or municipal records
If your building is borderline (constructed in 1973–1974), request a certified letter from the Assessor confirming the exact construction year. DHPD audits often target buildings with unclear construction dates because disputes over coverage liability are common.
The Rent Stabilization Code (RSC) and Allowable Rent Increases
If your building is covered under ETPA and your municipality has adopted RSC, your rents are stabilized. This means:
- Rent increases are limited to an amount set by the local Rent Guidelines Board
- You cannot refuse to renew a lease except for "good cause" (non-payment, lease violations, owner occupancy in some cases)
- Lease renewal notices must follow strict procedural rules
The Rent Guidelines Board and Annual Allowable Increases
Each Westchester municipality with RSC maintains a Rent Guidelines Board (RGB) comprised of tenant representatives, landlord representatives, and public members. The RGB meets annually and publishes allowable rent increase percentages.
As of 2026, the Westchester Rent Guidelines Boards have set the following ranges for annual increases:
| Municipality | 2026 Allowable Increase (1-Year Lease) | 2026 Allowable Increase (2-Year Lease) |
|---|---|---|
| Yonkers | 0.00% – 1.50% | 1.25% – 2.75% |
| New Rochelle | 0.00% – 1.25% | 1.00% – 2.50% |
| Mount Vernon | 0.00% – 1.50% | 1.25% – 2.75% |
| Pelham | 0.00% – 1.00% | 0.75% – 2.00% |
Critical compliance rule: You cannot charge rent above the RGB-approved amount. If the board approves a 1.5% increase and you charge 2%, you are in violation. The tenant can file a complaint with DHPD, which will investigate and order you to refund the overcharge plus interest.
The RGB percentage is the maximum you can increase. You may elect to increase by a lower percentage or offer no increase at all. However, you cannot exceed the approved cap under any circumstance.
How to Find Your Municipality's RGB Order
Each year, the RGB publishes its order, usually by March 31. You can locate your municipality's RGB order by:
- Contacting the municipality's Department of Housing or Planning directly
- Checking the Westchester County Rent Guidelines Board website (if centralized)
- Visiting your town or city clerk's office
- Requesting a copy from your local landlord association (Yonkers Landlord Association, New Rochelle Property Owners Association, etc.)
Do not estimate or assume. Obtain the official RGB order in writing. If you increase rent based on an outdated or incorrect percentage, DHPD will not accept "I didn't know" as a defense.
Unit Registration Requirements
One of the most overlooked compliance requirements: you must register covered units with the municipality. Registration establishes the legal status of a unit as stabilized and creates the baseline for allowable increases.
Registration Deadlines and Penalties
Each Westchester municipality with RSC requires annual registration. The deadline is typically April 30 each year, though this varies by municipality. Late registration may result in:
- Loss of your right to collect rent
- Forfeiture of your right to evict for non-payment
- Back registration fees and penalties
- Tenant claims for damages or unjust enrichment
This is a severe penalty. A tenant in an unregistered unit can argue that you have no legal right to collect rent from them. Courts have upheld this defense, leaving landlords unable to pursue eviction or collect outstanding rent.
What Registration Requires
When registering a unit, you must typically provide:
- Unit address and identifier
- Number of rooms and occupancy date
- Current rent
- Date of last lease renewal
- Tenant name (required by some municipalities)
- Owner/landlord contact information
Registration is conducted online in most Westchester municipalities. Contact your town/city housing department for the registration portal or form.
Compliance checklist: Set a calendar reminder for April 1 each year. Verify the exact deadline with your municipality. Register all covered units by the deadline. Save confirmation of registration.
Lease Renewal Notice Requirements and "Good Cause" Eviction Rules
Stabilized tenancies cannot be terminated at will. You can renew a lease or refuse renewal only for "good cause."
What Constitutes "Good Cause"?
Good cause for lease non-renewal typically includes:
- Non-payment of rent — Tenant owes rent for 30+ days
- Lease violations — Tenant violates a material term of the lease (e.g., unauthorized occupants, illegal activity, damage to unit)
- Owner occupancy (limited) — In some municipalities, you may refuse renewal if you or a family member will occupy the unit; this often requires 6+ months' notice and additional procedures
- Withdrawal of building from rental market — Requires municipal approval and typically 6–12 months' notice
- Major renovation requiring vacancy — Requires pre-approval and tenant relocation assistance
You cannot refuse renewal based on:
- Tenant's status as a protected class (race, color, national origin, disability, familial status, etc.)
- Tenant's exercise of legal rights (complaints to housing department, rent strike for habitability issues)
- Tenant's refusal to accept an illegally high increase
- General desire to get a higher-paying tenant
Lease Renewal Notice Timelines
If you intend to renew a lease at an increased rent (within RGB limits), you must provide written notice at least 90–150 days before lease expiration. The exact timeline depends on your municipality:
- Yonkers: 90 days before expiration
- New Rochelle: 120 days before expiration
- Mount Vernon: 90 days before expiration
- Pelham: 90 days before expiration
The notice must include:
- Current lease term and expiration date
- Proposed new rent amount
- Proposed new lease term (usually 1 or 2 years)
- Statement of tenant's right to accept or reject the renewal
- Effective date of new lease (if accepted)
- Reference to allowable increase percentage or RGB order
Failure to provide timely, proper notice can result in automatic lease renewal at the current rent plus the allowable increase (no increase if you failed to provide notice). Tenants can also claim damages if you fail to renew properly.
If You Refuse Renewal (Good Cause Termination)
If you refuse to renew a stabilized lease for good cause (e.g., non-payment), you must:
- Provide written notice of non-renewal at least 30 days before lease expiration
- State the good cause reason clearly and in detail
- Give tenant opportunity to cure if the violation is curable (e.g., pay overdue rent, remedy lease violation)
- If tenant disputes the good cause or refuses to vacate, pursue holdover eviction through court
Do not attempt "self-help" eviction (lockouts, utility shutoffs, removal of belongings). This is illegal and subjects you to damages, attorney fees, and criminal penalties under New York Property Maintenance Code.
Overcharge Complaints and DHPD Enforcement
If a tenant believes you have violated RSC rules (charged rent above the allowable increase, failed to register the unit, demanded illegal fees, etc.), they can file a complaint with the Department of Housing Preservation and Development (DHPD).
DHPD's Authority and Investigation Process
DHPD has jurisdiction over rent stabilization violations in Westchester municipalities. When a complaint is filed, DHPD will:
- Notify you of the complaint and provide an opportunity to respond (typically 20 days)
- Investigate the complaint by reviewing lease documents, rent payment records, and registration status
- Issue a determination (violation found or not found)
- If violation found, order remedies (refund, penalties, or both)
You have the right to appeal DHPD determinations to the state housing authority or court.
Penalties for Overcharge Violations
If DHPD finds you charged rent above the allowable increase, penalties include:
- Refund of the overcharge — All rent collected above the RGB-approved amount
- Interest — Typically 6% per annum on the overcharge amount
- Treble damages — In cases of willful violation, DHPD or courts may order damages of 3x the overcharge amount
- Attorney fees and costs — If tenant prevails, landlord may be ordered to pay tenant's legal fees
- Civil penalties — $500–$5,000 per violation, depending on severity and prior violations
Example: You charged a tenant $1,500/month but the allowable increase was only $200/month. The overcharge is $1,300/month. If the violation lasted 12 months, the total overcharge is $15,600. DHPD would order you to refund $15,600 plus 6% interest ($936). If DHPD finds willful violation, treble damages could total $46,800.
Other Common Violations and Penalties
| Violation Type | Penalty Range | Tenant Remedy |
|---|---|---|
| Failure to register unit | $500–$2,500 per year; loss of rent collection rights | Rent abatement defense; bar eviction for non-payment |
| Illegal lease charges (broker fees, app fees) | $250–$1,000 per charge; plus refund | Refund plus damages |
| Failure to renew lease on time | $250–$750; automatic renewal at old rent | Continued tenancy at old rent; damages possible |
| Retaliatory lease non-renewal | $1,000–$5,000 plus treble damages | Lease reinstatement; damages for lost housing |
| Demand for illegal fees (key money, capital improvement) | $500–$2,500 per demand | Refund plus treble damages |
Prohibited Lease Terms and Fees
Under RSC, you cannot charge or demand certain fees, even if a tenant agrees to them.
Illegal Fees and Charges
- Key money — Payment demanded in exchange for granting a lease; this is per se illegal regardless of whether the tenant voluntarily offers
- Capital improvement surcharges — Attempted to circumvent RSC by passing building improvements to tenants via "surcharge"; prohibited unless part of base rent calculation and pre-approved
- Illegal lease modifications — Charging for the "privilege" of lease modification; prohibited
- Parking or garage fees beyond actual costs — Must be reasonable and documented
- Application or screening fees exceeding actual costs — Cannot be used as profit center
- Lease signing or administrative fees — Cannot be charged; lease is a legal requirement, not an extra service
These prohibitions are absolute. A tenant cannot waive them, and you cannot enforce such fees even if the lease contains them.
How to Stay Compliant: A Self-Managing Landlord's Checklist
To avoid DHPD complaints, penalties, and tenant disputes, follow this compliance framework:
At Lease Commencement
- ☐ Verify your property's construction date with Westchester County Assessor
- ☐ Confirm your municipality has adopted RSC (contact Planning/Housing Department)
- ☐ If covered: register the unit with the municipality before tenant moves in
- ☐ Obtain a copy of the current RGB order and confirm allowable lease amount
- ☐ Provide tenant with written lease that complies with RSC terms
- ☐ Do not demand key money, capital improvement fees, or illegal charges
- ☐ Save confirmation of unit registration in your records
During Tenancy
- ☐ Do not increase rent mid-lease
- ☐ Maintain detailed rent payment records (amount, date, method)
- ☐ If tenant is late on rent, provide written notice and opportunity to cure before pursuing eviction
- ☐ Do not retaliate against tenants who file housing complaints or exercise legal rights
Before Lease Renewal or Non-Renewal
- ☐ Obtain current year's RGB order (confirm you have the correct percentage)
- ☐ Verify municipality's notice deadline (90–150 days before expiration)
- ☐ If renewing: calculate proposed rent (current rent + RGB percentage) and provide written notice
- ☐ If not renewing: clearly state "good cause" reason in writing and allow cure opportunity if applicable
- ☐ Ensure notice includes all required information and is delivered on time
- ☐ Save proof of notice delivery (certified mail receipt, email delivery confirmation)
Annually
- ☐ By April 1: Confirm re-registration deadline with municipality
- ☐ Re-register all units before deadline
- ☐ Save registration confirmations
- ☐ Obtain new year's RGB order for planning next lease renewals
Tools to automate this: LeaseBase's Compliance Engine can track registration deadlines, RGB orders, and lease renewal requirements by municipality, flagging upcoming deadlines before they lapse. For landlords managing multiple Westchester properties across different municipalities, centralized tracking prevents costly mistakes.
Common Compliance Mistakes and How to Avoid Them
Mistake #1: Assuming All Westchester Properties Are Stabilized
Reality: Only municipalities with adopted RSC ordinances have stabilization. Many Westchester towns do not.
Solution: Contact your municipality's housing department and get written confirmation of coverage status.
Mistake #2: Using NYC's RGB Percentages for Westchester Properties
Reality: NYC and Westchester maintain separate RGB boards with different percentages. Using NYC numbers for a Yonkers property is a violation.
Solution: Obtain the specific municipality's RGB order each year. LeaseBase's Compliance Engine maintains municipality-specific RGB databases.
Mistake #3: Late or Missing Unit Registration
Reality: Failure to register strips you of rent collection and eviction rights. Tenants can argue they owe no rent.
Solution: Register by April 30. Set calendar reminders on March 1 and April 1. Save all registration confirmations.
Mistake #4: Charging Above the RGB Percentage
Reality: Overcharges trigger DHPD investigation, refund orders, interest, and potentially treble damages.
Solution: Calculate new rent using the formula: Current Rent × (1 + RGB%) = New Rent. Round down if necessary. Document the RGB order supporting your calculation.
Mistake #5: Attempting Lease Non-Renewal Without Good Cause or Proper Notice
Reality: Retaliatory non-renewal or notice violations result in automatic lease renewal at old rent and potential damages.
Solution: If pursuing non-renewal, clearly document the good cause (non-payment, lease violation with evidence). Provide notice at least 90 days before expiration. Save all documentation.
Dispute Resolution and When to Seek Legal Counsel
If a tenant files an DHPD complaint or threatens legal action, do not ignore it. DHPD complaints are serious and have real penalties.
DHPD Complaint Response
When notified of a complaint, you typically have 20 days to respond. Your response should:
- Address each allegation point-by-point
- Include copies of all relevant lease, rent payment, and registration documents
- Explain your position clearly and factually
- Not include accusations or defensive language that appear evasive
If you lack clear documentation, seek legal counsel before responding. A qualified attorney can help you prepare a response that protects your interests.
Appeal Rights
If DHPD issues a violation determination against you, you have the right to appeal to the state (Housing Finance Agency or similar authority) or court. Appeals are technical and benefit from legal representation.
When to Hire an Attorney
Consult a qualified landlord-tenant attorney if:
- You receive an DHPD complaint or violation notice
- A tenant threatens legal action or claims overcharge
- You are uncertain about your municipality's RSC coverage or rules
- You plan to refuse lease renewal and want to ensure compliance with "good cause" requirements
- You face a holdover (eviction) proceeding
Westchester County Bar Association: (914) 948-4840. Request referrals to landlord-tenant specialists.
Monitoring Regulatory Changes: 2024–2026 Updates
Westchester RSC rules have been stable, but RGB percentages change annually and municipalities occasionally update coverage rules. Stay informed by:
- Subscribing to your municipality's housing department email updates
- Checking the Westchester County Rent Guidelines Board website (if centralized) or individual town boards
- Joining local landlord associations (Yonkers Landlord Association, etc.), which distribute RGB orders and compliance alerts
- Using LeaseBase's Analytics & Reporting dashboard to monitor lease expiration dates and RGB renewal deadlines by property
As of October 2026, no major statutory changes to Westchester RSC are pending, but enforcement activity has increased as DHPD has expanded audits in Yonkers and New Rochelle. Proactive compliance is your best defense.
Technology Solutions for Multi-Property Compliance

FAQ: Westchester Rent Stabilization Compliance
Q: My building is in Yonkers and was built in 1974. Am I covered by RSC?
A: No. ETPA coverage is limited to buildings constructed before January 1, 1974. A 1974 building is not covered. Verify the exact construction date with the Westchester County Assessor. If your property is borderline, request a certified assessment letter.
