Understanding NYC's Rent Stabilization Laws: What Tenants Need to Know

Landlord and Tenant Law · Aug 12, 2026

New York City's rent stabilization system covers roughly one million apartments, but most tenants only learn how it actually works when something goes wrong — an unexpected rent jump, a landlord who won't renew a lease, or a preferential rent that suddenly disappears. Here's what the rules actually say, including the major changes from 2019 that most people still don't know about.

What rent stabilization actually covers

Rent stabilization generally applies to buildings with six or more units built before 1974, along with many newer buildings that received certain tax abatements (like 421-a) in exchange for stabilizing some or all of their units. It's a different system from rent control, which is a much smaller, older program limited to tenants who've continuously occupied a pre-1947 building since before 1971 — rent control covers under 25,000 units citywide today and is gradually disappearing as those tenancies end.

Both systems are overseen by the state's Division of Housing and Community Renewal (DHCR), part of NYS Homes and Community Renewal (HCR). If you're not sure whether your apartment is stabilized, DHCR maintains a free building search tool — though a "no record" result doesn't automatically mean you're uncovered, since registration errors do happen.

The 2019 law that changed everything

The Housing Stability and Tenant Protection Act (HSTPA), passed in June 2019, was the biggest overhaul of NYC tenant protections in decades. A few changes from that law still shape almost every stabilized tenancy today:

Preferential rent is now permanent. Before 2019, landlords could offer a "preferential rent" — a rent below the official legal regulated rent on file with DHCR — to fill a vacancy, then jump the rent back up to the higher legal amount at renewal, sometimes by hundreds of dollars overnight. HSTPA ended that practice. If you were paying a preferential rent on a lease in effect on or after June 14, 2019 — regardless of when that preferential rent first began — it's now your base rent for as long as you stay. The landlord can only raise it by the standard guideline percentage, not reset it to the legal regulated rent.

Vacancy decontrol is gone. Before 2019, a stabilized apartment could exit the system entirely once the legal rent or a high-earning tenant's income crossed a set threshold — known as high-rent and high-income deregulation. HSTPA fully repealed both. Apartments still occasionally leave rent stabilization today, but only through narrow, unrelated pathways — like a building's tax abatement expiring or a unit undergoing substantial rehabilitation — not because the rent got high enough.

Renovation-based rent increases are capped. Landlords can still raise rent for building-wide improvements (MCIs) or individual apartment renovations (IAIs), but both are now more limited than before 2019. MCIs require the landlord to file a full application with DHCR, notify affected tenants, and receive a formal order before the increase can be charged — tenants have the right to respond and challenge it. IAIs work differently: a landlord doesn't need DHCR approval before charging the increase, only a notification filing with before-and-after photos, plus the tenant's written consent if the apartment is occupied during the work. Standard IAI costs are capped at $30,000, amortized over 15 years. A higher $50,000 cap is available only with prior DHCR certification, for apartments either occupied by the same tenant for 25+ years or registered vacant with DHCR for three consecutive years — that higher tier amortizes over 12 or 13 years depending on building size.

How much can your rent actually go up?

Rent stabilization doesn't freeze your rent — it caps how much it can increase at renewal, and that cap is set annually by the NYC Rent Guidelines Board (RGB), a mayoral-appointed body separate from DHCR.

For leases commencing between October 1, 2025 and September 30, 2026, the RGB set increases at 3% for a one-year renewal and 4.5% for a two-year renewal, per RGB Order #57. These percentages apply to your legal regulated rent (or your preferential rent, if HSTPA's permanent-preferential-rent protection applies to you) — not to whatever number a landlord might propose. The RGB sets a new percentage every year, so it's worth checking the current order before signing any renewal.

Your right to renew

One of the core protections of rent stabilization is DHCR Fact Sheet #4: if you're a tenant in good standing, you have an automatic right to renew your lease. Unlike a market-rate tenant, a landlord generally can't simply decline to renew a stabilized lease without a specific legal basis (like a documented lease violation or the landlord's own use of the unit under narrow circumstances). You don't need to request or negotiate the renewal — it's a right, not a favor.

Succession rights

If you've been living with a family member in their stabilized apartment and they pass away or permanently move out, you may be able to take over the lease through succession rights. Qualifying relationships generally include a spouse, children, parents, siblings, grandparents, grandchildren, or someone who can demonstrate a long-term relationship with genuine emotional and financial interdependence with the tenant of record. Succession claims are fact-specific and often contested, so documentation — shared leases, mail, joint accounts, tax filings — matters a lot if this situation applies to you.

A newer, separate protection: Good Cause Eviction

In April 2024, New York enacted a separate law called Good Cause Eviction, which extends some protections to tenants who are not in rent-stabilized apartments. It applies to units in NYC buildings with 10 or more apartments built before 2009 (with various exemptions). Good Cause doesn't cap your rent the way stabilization does, but it does require landlords to have a legally recognized reason — like nonpayment or a lease violation — before declining to renew, and it lets tenants challenge rent increases above roughly 10%, or 5 percentage points above inflation, whichever is lower, as presumptively unreasonable. If you're in a non-stabilized apartment in a larger, older building, it's worth checking whether Good Cause applies to you.

What to do if you think you're being overcharged

If your rent has been raised beyond what the law allows — or your preferential rent was improperly eliminated — you can file a rent overcharge complaint with DHCR. Overcharge cases can result in the landlord owing you back the excess, and in some circumstances, treble (triple) damages. Keeping your lease history, renewal notices, and any rent receipts is the single most useful thing you can do to protect yourself if a dispute comes up later, since DHCR complaints are decided heavily on paper documentation.

The bottom line

Rent stabilization is a genuinely complex system, and the rules shift depending on when you moved in, when your building was built, and what's happened to your lease since 2019. The broad takeaway from the HSTPA reforms is that the law now leans more protectively toward tenants than it did a decade ago — preferential rents stick regardless of when they started, deregulation pathways are largely closed, and renovation-based increases are capped and, for MCIs, require formal approval. But the specifics of any individual situation — a succession claim, an overcharge dispute, a Good Cause question — often turn on details that are worth reviewing with an attorney rather than guessing at.
