New York City’s rent stabilization program is the largest source of affordable rental housing in the United States. It is also one of the most poorly understood — by the people it’s meant to protect. Scroll on.
About 2,300,000 rental homes in New York City.
Every dot is roughly 23,000 apartments — every walk-up, brownstone floor-through, prewar tower and post-war elevator building you’ve ever passed.
About 1,000,000 are rent-stabilized.
Almost half. The orange tiles below — that’s the mechanism keeping a million NYC households inside the city they grew up in.
For comparison public housing covers ~170k.
NYCHA — the largest public housing authority in North America — covers a fraction of what stabilization does. It is the affordability program no one campaigns on.
By design, rent stabilization measures generally have wider coverage than other housing affordability policies or programs.
“Around a third of households cannot correctly report their rent stabilization status. Rent discounts are significantly larger for households correctly aware of their benefits, with a mean monthly discount of $645 vs $218 for those unaware.”
Longer-tenured renters benefit more because they accumulate savings for longer.
Your lease begins.
You sign at $2,000/month. Whether or not you know it, the apartment is stabilized.
A renewal arrives.
The Rent Guidelines Board has set a 1.5% renewal increase. The legal rent ticks up to $2,030. Your landlord’s offer reads $2,150.
The gap compounds.
Every year the legal rent grows by a board-set increase. Every year the actual rent grows faster. By year five the spread is roughly $400 per month.
The bill, made visible.
Across a decade you have paid tens of thousands of dollars above the legal rent. None of it shows up on your lease. It shows up only when you compare two lines.
only six years are recoverable.
The HSTPA statute of limitations caps your claim at the most recent six years. Anything older is real, but not recoverable. The shaded band shows what is still on the table.
Before 2019, a tenant could only recover four years of overcharge. The Housing Stability and Tenant Protection Act of 2019 — HSTPA — extended the lookback to six and, for willful overcharges, opened the door to triple damages. But the clock still runs.
Four-year lookback. Most claims expired before tenants ever knew to file.
Six years recoverable, plus treble damages for willful overcharges.
This illustrates the policy opacity, which may prevent lower educated and newcomers to the city to benefit from it, and provide room for landlords to control who they advertise the rent-stabilized status to.
Ledger answers two questions: is my building rent-stabilized? and given my lease history, am I being overcharged? If the answer to the second is yes, it drafts a complaint you can take to DHCR.
We search NYC Planning Labs’ geocoder for your address, then check the normalized BBL against the NYCDB rentstab_v2 dataset.
If you enter a lease history, we apply Rent Guidelines Board orders #1–#57 to compute the legal renewal rent at every step and flag where the actual rent went higher.
We pre-fill DHCR Form RA-89 — Tenant’s Complaint of Rent Overcharges — with your numbers, ready for a tenant attorney’s review.
A real overcharge case may involve MCI and IAI adjustments, vacancy allowances, fraud claims, and other facts this tool can't see.
The authoritative starting point for any case is your apartment’s registered rent history, requested via DHCR Form REC-1.
NYCDB coverage runs through roughly 2023; newly-stabilized or de-regulated buildings may show stale information. Cross-check on the DHCR Building Search.
