How this calculator works
Before a rent increase can take effect on a month-to-month tenancy, nearly every state requires advance written notice — anywhere from one rental period (Texas, under Tex. Prop. Code § 91.001) to 90 days (Oregon, and California for increases over 10%). Fixed-term leases work differently: the rent is locked until renewal unless the lease has an escalation clause. A few jurisdictions also cap the size of the increase — California's AB 1482 (5% + CPI, max 10%), Oregon's statewide cap, Washington's 2025 cap, DC rent stabilization, and New York's Rent Guidelines Board for rent-stabilized units. This tool combines those rules and computes your percent increase. See also our state guides on Texas and Maryland rent increase rules.
FAQ
How much notice does a landlord have to give before raising rent?
It varies by state — from one rental period (Texas and several states with no specific rent-increase statute) up to 90 days (Oregon; California for increases over 10%; Maryland for longer tenancies). Common requirements are 30 days, 60 days (Colorado, Delaware, Nevada, Vermont, Washington), and tiered periods based on tenancy length (New York: 30/60/90 days). Select your state above for the exact rule and citation.
Can a landlord raise rent in the middle of a fixed-term lease?
Generally no. During a fixed-term lease the rent is locked in until the term ends, unless the lease itself contains an escalation clause explicitly allowing a mid-term increase. Increases normally take effect at renewal or, for month-to-month tenancies, after the required written notice period.
Which states have statewide rent control?
California (AB 1482: 5% + local CPI, hard-capped at 10%/year for covered buildings), Oregon (lesser of 10% or 7% + CPI for buildings 15+ years old), and Washington (2025 law: generally 7% + CPI, max 10%, for covered units). New York caps increases on rent-stabilized units through the Rent Guidelines Board, and DC rent stabilization caps most increases at CPI + 2%. Many cities in other states (New Jersey, Maryland, Minnesota) have local ordinances.
What happens if a landlord gives less notice than required?
The increase is generally unenforceable until proper notice has been given and the full statutory period has run. The tenant owes only the original rent in the meantime, and the landlord must re-serve a compliant notice.
Is this calculator legal advice?
No. It provides general information about state statutes and is not legal advice. Notice periods and caps change, and many cities have local ordinances stricter than state law. Verify the current statute or consult a licensed attorney in your jurisdiction.
