Frequently asked questions

How much notice do landlords have to give for a rent increase?

Typically 30 days for month-to-month tenancies, but many states require 60 or 90 days for larger increases. Rent-control jurisdictions (California, Oregon, parts of NY/NJ) have stricter notice and dollar limits — the calculator shows your state's rule.

Is there a legal limit to how much rent can go up?

In most U.S. states there is no statewide cap on rent increases for market-rate units. California (AB 1482), Oregon (statewide cap), and several cities (NYC, SF, LA, etc.) do impose caps. The calculator flags whether your state has one and what it is.

What's a reasonable annual rent increase?

In a typical year, landlords raise rent 3–5% to track inflation and property costs. Larger increases are usually justified by market shifts (a 10%+ rise in comparable rents), major property improvements, or a long-frozen rent that's well below market.

Can I generate the notice letter from the calculator?

Yes — once you enter the new rent and effective date, the calculator drafts a state-compliant rent-increase notice letter that you can copy or download.
