Use our free rent increase checker tool to find out if your landlord’s rent increase is legal, whether you received enough notice, and what protections your state provides. Enter your current and proposed rent below — results are instant and based on verified state law.
How to Use This Rent Increase Checker Tool
Step 1: Select your state and enter your current rent. Every state has different rules about rent increases. Only California, Oregon, and Washington have statewide rent caps — most states have no limit on how much a landlord can raise rent. The rent increase checker tool covers all 50 states.
Step 2: Enter your proposed new rent. The tool instantly calculates the percentage increase and checks it against your state’s cap (if one exists). An increase of 20% or more is flagged as significant regardless of state law.
Step 3: Enter how many days’ notice your landlord gave. Even in states with no rent cap, landlords must give proper written notice before a rent increase takes effect. The tool checks whether your landlord met the notice requirement, which ranges from 10 days (Louisiana) to 90 days (Oregon).

What Your Results Include
The rent increase checker tool gives you a clear verdict — legal, possibly illegal (exceeds state cap), or insufficient notice — along with a full breakdown showing the dollar increase, percentage increase, your state’s cap (if any), and the notice required versus what your landlord gave.
States with statewide rent caps (California under AB 1482, Oregon under SB 608, and Washington under HB 1217) are flagged in green with the exact cap percentage. States where local cities may have their own rent control ordinances (like New Jersey, New York, Maryland, Maine, and Minnesota) show an amber warning reminding you to check your city’s rules. Every result links to your state’s full rent increase guide.
If your landlord did not give enough notice, the tool explains that the increase may not be enforceable until proper notice is provided. This is true even in states with no rent cap — the notice requirement still applies.
Frequently Asked Questions
How accurate is the rent increase checker tool?
Every figure was verified against primary state statutes and official sources as of June 2026, including the three statewide rent cap laws (California AB 1482, Oregon SB 608, Washington HB 1217). Notice periods were cross-checked against iPropertyManagement and Nolo. However, local city ordinances can add stricter rules — always check with your city government or a legal-aid office.
Does this rent increase checker tool give legal advice?
No. This tool provides general legal information based on state statutes. It is not a substitute for professional legal advice. If you believe your rent increase is illegal, contact a local tenant rights attorney or a free legal-aid organization in your state.
Can my landlord raise rent by any amount?
In most states, yes — there is no limit on the amount. Only California, Oregon, and Washington have statewide rent caps. However, some cities in states like New Jersey, New York, Maryland, and Minnesota have local rent control ordinances that cap increases. The rent increase checker tool flags these states so you know to check your city’s rules.
How much notice does my landlord have to give?
Most states require 30 days’ written notice for a month-to-month rent increase. Some require more: Oregon needs 90 days, Delaware and Georgia need 60 days, and Nevada and Hawaii need 45 days. California requires 90 days for increases over 10%. The tool checks your state’s specific requirement and tells you whether your landlord met it.
What if my city has rent control but my state doesn’t?
Some states allow cities to pass their own rent control laws even without a statewide cap. Over 100 cities in New Jersey have local rent control. New York City has rent stabilization. St. Paul, Minnesota passed a 3% cap. Portland, Maine has a cap tied to CPI. The tool flags these states with a ‘Check Your City’ warning so you know to verify your local rules. Use your eviction timeline calculator if you are also facing eviction.
