Can a New York tenant dispute a rent increase?
Yes, on specific legal grounds: the notice was defective (wrong form, wrong advance period, wrong effective date), the increase exceeds the applicable cap (if New York has one), the unit is rent-stabilized or rent-controlled under local ordinance, or the increase is retaliatory (in response to a tenant complaint, code-compliance request, or organizing). New York uses a tenure-based notice ladder at RPL 226-c: 30 days for tenancies under 1 year, 60 days for 1-2 years, 90 days for 2+ years. Only triggers if the increase exceeds 5% or the landlord does not renew. Good Cause Eviction (Part HH 2024) caps increases at CPI + 5% or 10% max in NYC and opt-in municipalities, with exemptions for small owner-occupied buildings and new construction. A tenant-lawyer consultation is recommended for any disputed increase.

This is an informational answer based on RPL 226-c (HSTPA 2019) as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a New York-licensed attorney.
