Test 1 — The cap (stabilized units only)
If the unit is rent-stabilized, the increase generally cannot exceed the Rent Guidelines Board rate for your renewal period. Anything above it appears to exceed the allowed amount.
Test 2 — The timing
An increase generally takes effect at lease renewal, not in the middle of a lease term. A mid-lease increase is worth questioning unless your lease clearly provides for one.
Test 3 — The written notice
Under NY RPL §226-c, an increase greater than 5% requires advance written notice of 30, 60, or 90 days depending on how long you have lived there. Verbal notice or a text message may not satisfy the statute.
- Under 1 year of tenancy → 30 days.
- 1 to 2 years → 60 days.
- 2 or more years → 90 days.
Test 4 — No retaliation
An increase that closely follows a complaint about repairs, a housing-code report, or tenant organizing may raise a retaliation question under NY RPL §223-b. Keep a dated record of both events.
If a test appears to fail
Put your questions in writing, keep copies, request your DHCR rent history, and consider consulting a licensed New York tenant attorney or a free legal-aid clinic before withholding any payment. Withholding rent carries its own risks.
Frequently asked questions
What makes a rent increase illegal in NYC?
Common issues include exceeding the Rent Guidelines Board cap on a stabilized unit, raising rent mid-lease, skipping the §226-c notice period, or an increase that appears retaliatory. Each is worth verifying with your paperwork.
Do I have to pay an increase that looks unlawful?
The unlawful portion is generally not enforceable, but that is a determination for DHCR or a court — not something to assume. Consider consulting a licensed attorney before changing what you pay.
How do I prove my unit is rent-stabilized?
Request your free Apartment Rent Registration History from DHCR. Past registrations are strong evidence of stabilization, as is a stabilization rider attached to your lease.
