Is a 10% rent increase legal in New York?
In New York a 10% increase is generally within the legal range because there's no statewide percentage cap, as long as you get 30 days' written notice.
Step-by-step answer
- Step 1
How the math checks out
Divide the new rent by the old rent and subtract 1. If the number is 0.10 that's 10%. In New York there is no percent cap, so the fairness test is more about notice, lease terms, and local rules.
- Step 2
What to do next
Even a legal increase can be negotiated. Ask about a longer lease, request a smaller increase in exchange for renewing early, and document what similar units in your area rent for.

The numbers that decide it
- Stabilized 1-year renewal
- 0%
- RGB Apartment/Loft Order #58, renewals commencing Oct 1, 2026 – Sep 30, 2027 (adopted June 25, 2026)
- Stabilized 2-year renewal
- 0%
- Same Order #58 — a freeze on both lease lengths
- Prior year (Order #57)
- 3% / 4.5%
- One-year / two-year renewals commencing Oct 1, 2025 – Sep 30, 2026
- Market-rate cap
- None
- No percentage ceiling — the check is notice, lease terms, and retaliation
- Notice for an increase over 5%
- 30 / 60 / 90 days
- Under 1 year / 1–2 years / 2+ years in the unit (RPL §226-c)
Figures change — verify against the official source before relying on them.
A 10% increase in New York, unit type by unit type
On a rent-stabilized apartment, 10% sits far above the current Rent Guidelines Board figure: Order #58 sets 0% for both one-year and two-year renewals commencing Oct 1, 2026 through Sep 30, 2027, and the prior Order #57 allowed 3% and 4.5%. A 10% renewal ask therefore appears to exceed the order in force and is worth verifying against your official HCR rent history. On a market-rate apartment, 10% can be lawful — the enforceable question becomes whether you received the correct §226-c notice, since any increase above 5% triggers the 30 / 60 / 90-day timeline.
Worked example
Worked example: $2,400 rent in Brooklyn
- Start with the current legal rent: $2,400 per month.
- Find out whether the unit is rent-stabilized. Most pre-1974 NYC buildings with 6 or more units are. Requesting your rent history from NY HCR is the reliable way to confirm it.
- If stabilized, apply Order #58 for renewals commencing Oct 1, 2026 – Sep 30, 2027: the one-year adjustment is 0%, so $2,400 × 0.00 = $0 and the renewal rent generally stays at $2,400.
- The two-year adjustment under the same order is also 0%, so a two-year renewal generally stays at $2,400 as well. For comparison, the prior Order #57 allowed 3% ($72, to about $2,472) on one year and 4.5% ($108, to about $2,508) on two years.
- If the notice says $2,750, that is a $350 jump — about 14.6%. On a stabilized unit that appears to exceed the Rent Guidelines Board rate and is worth verifying against the current Order.
- If the unit is market-rate, there is no percentage ceiling, so the check shifts to notice: a 14.6% increase is over 5%, so §226-c notice timing (30, 60, or 90 days depending on how long you have lived there) applies.
Same dollar amount, two very different answers — which is why confirming stabilization status first matters more than the percentage itself.
