Sometime between late January and early spring, a small notice appeared in the lobby of every NYC building that contains at least one rent-stabilized apartment. The text is unremarkable. The bilingual posting reads, in plain language:
This building contains one or more units that are subject to rent stabilization. To find out if your unit is rent stabilized, contact New York State Homes and Community Renewal.
That is the entirety of the new law's most visible artifact. Local Law 86 of 2025, also known as the Rent Transparency Act, took effect January 26, 2026. It applies to any multiple dwelling with three or more units that contains at least one rent-stabilized apartment. The Department of Housing Preservation and Development is the enforcement agency. Civil penalties apply for non-compliance.
The thing the sign does not say is the more interesting story.
What the original law would have said
The version of Intro 1037 introduced by Council Member Sandy Nurse last year was substantially more aggressive than the version that took effect.
The original draft would have required landlords not only to acknowledge the existence of rent-stabilized units but to disclose that failure to file proper registrations with the state could expose them to penalties. It would have required landlords to provide tenants with updated DHCR registration filings each year — annual proof, in writing, of the legal regulated rent for that unit.
That language was removed before passage.
What survived is a posting requirement that informs tenants the building contains some stabilized units, without telling them which ones, what their rents are, or whether the landlord has filed the required paperwork. The tenant is told to "contact DHCR" to find out the rest.
The sign acknowledges a fact. It does not provide it.
Why the gap matters
Rent stabilization in New York covers roughly two million people. The law that protects them depends on landlords accurately filing each unit's status with DHCR every year. When the filings are accurate, a tenant who suspects an overcharge can request the unit's rent history, see the legal regulated rent, and challenge the discrepancy.
When the filings are not accurate — or are missing entirely — the tenant has no way to know.
The Castillo settlement in April, the BlueSky settlement in December, and a long string of state Tenant Protection Unit enforcement actions over the past three years have established the same pattern: landlords with stabilized portfolios sometimes fail to register units, allowing the actual regulatory status to drift out of the public record. When state investigators eventually examine a portfolio in aggregate, they find apartments paying above the legal regulated rate — sometimes for years, sometimes for decades.
The Rent Transparency Act, in its final form, does not address this gap. It tells the tenant to contact the state. The state may or may not have current information for the tenant's specific unit, depending on whether the landlord has filed.
For a tenant who has already received a sticker shock at lease renewal, this is an additional research step on top of an already opaque process. The sign in the lobby is the first hint. The work begins after.
What the sign actually changes
The honest read is that the law is symbolic more than mechanical.
Before January 26, a renter signing a lease in a rent-stabilized apartment received no automatic notification that the apartment was stabilized. Some tenants knew. Many did not. Brokers were not legally required to mention it. Landlords had no incentive to.
After January 26, every renter who walks into a building with at least one stabilized unit will see — somewhere — a posted notice in English and Spanish saying that stabilized units exist in the building.
That is meaningful. It is also limited.
The sign does not tell you whether your unit is one of them. It does not tell you the legal regulated rent of any unit. It does not tell you whether the landlord's DHCR filings are current. It does not give you any specific information that would help you challenge an overcharge.
It tells you that the question is worth asking.
What an actual rent-stabilization check looks like
For a tenant who walks past the new sign and wants to know what their unit's status actually is, the process is the same as it was before the law passed:
Request your unit's rent history from DHCR. The form is one page. The request is free. Processing takes about ten business days. The result is a year-by-year record of the registered legal regulated rent for your unit, going back as far as the building has been registered.
Compare the registered legal rent to what you are paying. If you are paying more than the registered legal rent, that is a documented overcharge. Overcharges can be recovered going back four years, with interest.
Check whether the landlord has registered your unit at all. Many of the recent state enforcement settlements have been triggered by buildings whose units stopped being registered years ago. An unregistered unit is not the same as a deregulated unit. The legal status persists. The paperwork lapsed. That distinction matters in court.
Cross-reference the building's broader portfolio. Landlords with one stabilized building have a different risk profile than landlords with sixty. If your landlord shows up on a portfolio with active enforcement actions, the rent on your specific unit is more likely to be one of the many being reviewed.
The longer picture
Rent stabilization is one of the most consequential regulatory frameworks in NYC housing, and one of the most opaque. The Rent Transparency Act is the city's smallest possible step toward making it less opaque.
The sign in the lobby will, over time, prompt a portion of unaware stabilized tenants to ask the question. Some of them will discover overcharges. Some of those will recover money. Some will move into housing court. Each of those tenants is a person who would not have known to look without the sign.
But for the rest — for the tenants who see the sign and assume it does not apply to them, or who contact DHCR and get a registered rent that does not match what is actually being charged, or who learn their landlord stopped filing registrations in 2018 — the sign is the start of the work, not the answer.
Information is power, the bill's sponsor said when the legislation passed. That remains true. The version of the law that survived gives tenants the smallest possible amount of it, and asks them to find the rest themselves.
Frequently Asked Questions
What does the rent-stabilization notice in my building lobby mean? It means the building contains at least one rent-stabilized apartment. Under the Rent Transparency Act (Local Law 86 of 2025), which took effect January 26, 2026, any multiple dwelling with three or more units that includes at least one rent-stabilized apartment must post a bilingual notice — typically in the lobby — telling tenants that stabilized units exist there and directing them to contact New York State Homes and Community Renewal (HCR). The Department of Housing Preservation and Development enforces it, with civil penalties for non-compliance. What the sign does not do is tell you which specific units are stabilized, or what their legal rents are — it simply flags that the question is worth asking for your own apartment.
What is the Rent Transparency Act (Local Law 86 of 2025)? It's a New York City law, effective January 26, 2026, requiring landlords of buildings with three or more units that contain at least one rent-stabilized apartment to post a notice informing tenants that stabilized units exist. It's the surviving, scaled-back version of a broader bill (Intro 1037): the original draft would have required landlords to give tenants updated DHCR registration filings each year — annual written proof of the legal regulated rent — and to disclose penalty exposure for failing to register. That language was removed before passage. What remains is a posting requirement that acknowledges stabilized units exist without saying which ones, what their rents are, or whether the landlord's filings are current.
Does the lobby sign mean my apartment is rent-stabilized? Not necessarily. The sign tells you the building contains one or more rent-stabilized units — not that yours is one of them. It doesn't identify which specific apartments are stabilized, doesn't state the legal regulated rent of any unit, and doesn't say whether the landlord's DHCR filings are current. So it's a prompt, not an answer: it tells you the question is worth asking for your own apartment. To actually confirm your unit's status, you'd request your apartment's rent history from HCR — the sign is the first hint, but the real work of confirming your status begins after you see it.
What doesn't the rent-stabilization sign tell me? Almost everything specific. It doesn't tell you which units in the building are stabilized, the legal regulated rent of any unit, or whether your landlord's DHCR filings are current — and that last gap matters most. Rent stabilization depends on landlords accurately registering each unit's status with the state every year; when filings lapse or go missing, a unit's real regulatory status can drift out of the public record, and tenants can end up paying above the legal rent for years. State enforcement settlements have repeatedly found exactly this pattern. Importantly, an unregistered unit is not the same as a deregulated one: the legal status persists even when the paperwork lapses. The sign flags none of this.
