Imagine getting a letter in your mailbox on a Tuesday. Your lease ends in three weeks. Your rent is going up $400. Surprise.

If that scenario makes your stomach drop, here's the law that's supposed to prevent it: NY RPL §226-c requires landlords to give written notice before raising your rent or declining to renew your lease. The timeline isn't a courtesy — it's a legal obligation.

How much notice are you actually owed?

Under §226-c, the required notice period scales with how long you've lived in your apartment. Tenants who have rented for less than one year are owed at least 30 days' notice. That 30-day floor is the baseline, and it kicks in regardless of what your lease says — the statute overrides a shorter contractual window.

Here's the part most renters miss: notice must be delivered before the start of the notice period, not on day one of it. If your lease ends October 31 and your landlord drops a rent-hike letter on October 1, that's cutting it close — and depending on how notice is served, it may not count at all.

What counts as proper notice?

The statute requires written notice. A text from your super doesn't qualify. A verbal heads-up in the hallway doesn't qualify. Your landlord must deliver something in writing — typically via certified mail or personal delivery — that clearly states the change and the effective date.

If notice isn't delivered correctly or on time, you may have grounds to challenge the rent increase or stay in your apartment past the stated end date. That's not a loophole — it's the statute working as intended.

If you're in a rent-stabilized unit, this gets layered

Rent-stabilized tenants have additional protections through NYS Homes & Community Renewal (DHCR) — including rules on allowable rent increases and lease renewal offers. §226-c notice rights apply on top of those, not instead of them.

The practical move

Mark your lease end date, then count back 30 days (or more, depending on tenancy length). If that deadline passes without written notice of a change, document it. Keep every piece of mail from your landlord. If a dispute lands in NY Housing Court, paper trails matter more than memory.
