If your rent-stabilized lease lists two different rent numbers — a higher "legal regulated rent" and a lower amount you actually pay — you have a preferential rent. It's one of the most misunderstood features of stabilized housing, and misunderstanding it has cost tenants real money. The good news: since 2019, the law protects preferential-rent tenants far more strongly than most of them realize.
At a glance
- Preferential rent is a rent an owner charges that is lower than the legal regulated rent they could lawfully collect.
- Since the 2019 HSTPA law, if you were paying a preferential rent on a lease that renewed on or after June 14, 2019, you keep that preferential rent for the length of your tenancy — the landlord can't spike it to the legal rent at renewal.
- Your annual increases are calculated on the preferential rent you actually pay, not the higher legal rent on paper.
- The legal regulated rent generally can't be collected until the apartment becomes vacant.
- The two numbers must both appear in your lease and rent history.
What preferential rent actually is
Every rent-stabilized apartment has a legal regulated rent — the maximum the owner is permitted to charge, registered with the state (HCR). Sometimes an owner chooses to charge less than that maximum, often to fill a vacancy in a soft market. That lower, actually-charged amount is the preferential rent. The gap between the two is the "preferential discount."
So a lease might show a legal regulated rent of $3,000 but a preferential rent of $2,200. You pay $2,200. The $3,000 sits on paper as the legal ceiling.
Before 2019, that paper ceiling was a trap: landlords could offer a low preferential rent to sign you, then at renewal "revoke" it and jump you to the full legal rent — hundreds of dollars overnight. That practice is what the 2019 law ended.
The 2019 change that protects you
The Housing Stability and Tenant Protection Act (HSTPA), effective June 14, 2019, rewrote the rules. Under current law, a preferential rent being collected must continue to be offered at each lease renewal — it can no longer be revoked mid-tenancy. In practical terms: if you began paying a preferential rent on or after June 14, 2019, that preferential amount is your base going forward under current HCR guidance, and future Rent Guidelines Board increases apply to it, not to the higher legal number.
This is a big deal. It means your rent-stabilized apartment behaves, for increase purposes, as if the preferential rent were the "real" rent. The legal regulated rent still exists on record — and generally cannot be collected during the current tenancy; it may become collectible upon vacancy, subject to applicable program rules and HCR guidance — but it can't be used to inflate your renewals while you live there. (One narrow exception context involves certain tax-benefit programs like 421-a; if your building has one, verify the specifics.)
How your increase is calculated
When your renewal arrives, the RGB guideline for that lease cycle is applied to the preferential rent you're paying. This year that math is unusually simple: the 2026-27 guideline is a freeze — 0% on both one- and two-year renewals — so a covered preferential rent stays exactly where it is (see our breakdown of the 2026 freeze). In a normal year, if the guideline were, say, 3%, your new rent would be your preferential rent plus 3% — not the legal rent plus 3%.
When you get a renewal, three checks protect you:
- Confirm the increase was applied to the preferential rent, not the legal regulated rent.
- Confirm both rents appear, consistently, on the renewal and the DHCR lease rider (Form RA-LR1).
- Watch for other line items — MCI or IAI increases — stacked on top; those follow separate rules and should be documented separately.
How to spot a problem
The classic red flag is a renewal that suddenly bills you at or near the legal regulated rent instead of your preferential amount — the exact move the 2019 law prohibits for post-June-2019 preferential tenancies. If you see it:
- Pull your official rent history from HCR (free) to see the registered legal and preferential amounts over time — this is the document that settles disputes. Not sure whether your unit is even stabilized? Here's how to check.
- If the numbers show you were overcharged, you can file a rent overcharge complaint with HCR; if an overcharge is found, you may be owed a refund with interest going back up to six years, and triple damages if it was willful.
Preferential rent turns a stabilized lease into an even better deal than it looks — but only for tenants who understand which number is theirs. For the full set of stabilized-tenant protections, see our rent stabilization resource center.
Frequently asked questions
Can a landlord remove my preferential rent? Not if your preferential-rent lease renewed on or after June 14, 2019. Under the Housing Stability and Tenant Protection Act (HSTPA), a preferential rent being collected must continue to be offered at each renewal for the life of your tenancy — the landlord can't revoke it and jump you to the legal regulated rent mid-tenancy. Before 2019, that paper ceiling was a trap: landlords could offer a low preferential rent to sign you, then "revoke" it at renewal and spike you to the full legal rent, sometimes hundreds of dollars overnight. The 2019 law ended that practice. So for any preferential tenancy dating to on or after June 14, 2019, the preferential amount is your base going forward.
What is the "legal regulated rent" then? It's the maximum rent the owner is legally permitted to charge for your unit — the ceiling registered with the state (HCR). With a preferential rent, that legal number sits on paper above what you actually pay: a lease might show a legal regulated rent of $3,000 but a preferential rent of $2,200, and you pay $2,200 while the $3,000 stays on record as the legal ceiling. The gap between them is the "preferential discount." Critically, the legal regulated rent generally can't be collected during your tenancy; it may become collectible only upon vacancy, subject to applicable program rules and HCR guidance. While you live there, it can't be used to inflate your renewals.
Does preferential rent last forever? It lasts for the length of your tenancy, for preferential tenancies dating to on or after June 14, 2019 — the landlord must keep offering it at every renewal while you live there. It isn't a forever-guarantee independent of you, though: it isn't inheritable as a separate thing, but a qualifying successor generally steps into your tenancy on the same terms, preferential rent included. And the underlying legal regulated rent doesn't disappear — it stays on record and generally becomes collectible only when the apartment becomes vacant. So the protection is tied to your continuing tenancy, not attached permanently to the apartment itself.
How is my increase calculated at renewal? The Rent Guidelines Board (RGB) guideline for that lease cycle is applied to the preferential rent you actually pay — not to the higher legal rent on paper. For the 2026-27 cycle that guideline is a freeze: 0% on both one- and two-year renewals, so a covered preferential rent stays exactly where it is. In a normal year the math is just as tenant-friendly: if the guideline were, say, 3%, your new rent would be your preferential rent plus 3%, not the legal rent plus 3%. When your renewal arrives, confirm the increase was applied to the preferential amount, and watch for MCI or IAI line items stacked on top, which follow separate rules.
How do I prove my preferential rent if there's a dispute? Order your official rent history from HCR — it's free, and it shows the registered legal and preferential amounts for your unit over time, which is the document that settles these disputes. Cross-check it against your lease and the DHCR lease rider (Form RA-LR1), where both rents should appear consistently. If the numbers show you were billed at or near the legal regulated rent instead of your preferential amount — the exact move the 2019 law prohibits for post-June-2019 tenancies — you can file a rent overcharge complaint with HCR. If an overcharge is found, you may be owed a refund with interest going back up to six years, plus triple damages if it was willful.
