Maximum rent increase allowed law questions often start with a letter taped to your door. Your landlord wants more money, and you want to know if that is legal. The answer depends on where you live. Only a few states set a statewide cap.
In most states, the rules are about notice, not about how big the increase can be. However, California, Oregon, and Washington now limit how much rent can go up each year. Some cities also have local rent control. This guide explains how the maximum rent increase allowed law works for renters in 2026. It also covers what you can do if an increase seems too high.
Is There a Maximum Rent Increase Allowed Law in Your State?
Most states have no cap on rent increases. As a result, a landlord in those states can typically raise rent by any amount. The limit is on timing. An increase usually cannot take effect in the middle of a fixed-term lease. It also needs proper written notice before it starts.
Many states also block cities from passing rent control. This is called “preemption.” The National Apartment Association counted 36 preemption states as of early 2026. For example, Texas Local Government Code § 214.902 bars cities from capping rent unless the governor declares a housing disaster. Georgia (O.C.G.A. § 44-7-19) and Florida have similar laws. In these states, no maximum rent increase allowed law exists at the state or local level.
However, a few places do set limits. California, Oregon, and Washington have statewide caps. New York, New Jersey, Maryland, Minnesota, and Washington, D.C. allow local rent control or rent stabilization in some areas. For example, New York City’s Rent Guidelines Board sets yearly limits for rent-stabilized apartments.
How Statewide Rent Caps Work in 2026
All three statewide caps use a similar formula. Each one ties the limit to inflation, measured by the Consumer Price Index (CPI). CPI is a government number that tracks how fast prices rise. Each state also sets a hard ceiling of 10%. Here is how the maximum rent increase allowed law compares in each state.
| State | Law | Formula | 2026 Cap | Key Rules for Tenants |
|---|---|---|---|---|
| California | Civil Code § 1947.12 (AB 1482) | 5% + regional CPI, max 10% | Varies by region, never above 10% | Covers most buildings 15+ years old; many single-family homes exempt |
| Oregon | ORS 90.323 (SB 611) | 7% + CPI, max 10% | 9.5% | 90 days’ written notice; no increase in the first year; one increase per 12 months |
| Washington | HB 1217 (2025) | 7% + CPI, max 10% | 9.683% | No increase in the first 12 months; 5% cap for manufactured homes |
Exemptions matter a lot. In California, the cap does not cover buildings built in the last 15 years. It also skips many single-family homes and condos, but only if the landlord gave you a written exemption notice. Oregon exempts buildings first occupied less than 15 years ago. Washington exempts new buildings for their first 12 years. It also exempts some owner-occupied duplexes, triplexes, and fourplexes.
You can check the official numbers yourself. Oregon posts its yearly figure on the Oregon DAS rent stabilization page. Washington posts its cap on the Washington Department of Commerce site. California’s rule is in Civil Code § 1947.12.
Notice rules apply even where no cap exists. In California, Civil Code § 827 requires 30 days’ notice for increases of 10% or less. Increases over 10% need 90 days’ notice. Oregon and Washington both require 90 days’ written notice. In Washington, the attorney general can seek up to $7,500 per violation. As a result, the maximum rent increase allowed law in these states has real enforcement power.
What to Do If an Increase Breaks the Maximum Rent Increase Allowed Law
Start by reading your lease. If you have a fixed-term lease, your rent typically stays the same until it ends. A month-to-month tenancy is different. There, the landlord can raise rent with proper notice.
Next, check the notice itself. Was it in writing? Did it give enough days? Was it delivered the way your state requires? A notice that falls short may not be valid. For example, an Oregon landlord who gives only 30 days instead of 90 has likely missed the rule.

Then do the math. Subtract your current rent from the new rent. Divide that number by your current rent. If you live in a capped state and the increase tops the limit, tell your landlord in writing. Keep copies of every letter and text. Also, look up your city’s rules. Your city may have a stricter maximum rent increase allowed law than your state.
Watch for retaliation. Many states ban rent hikes meant to punish you for asking for repairs or filing a complaint. For example, California Civil Code § 1942.5 protects tenants for 180 days after certain complaints. If an increase seems retaliatory or illegal, contact a local legal-aid office. You can find free help through the Legal Services Corporation.
Frequently Asked Questions
Is there a maximum rent increase allowed law in every state?
No. In most cases, there is no statewide cap at all. However, California, Oregon, and Washington cap yearly increases at 10% or less. Some cities in other states also have local rent control.
Can my landlord raise rent in the middle of my lease?
Typically, no. A fixed-term lease locks in your rent unless the lease itself allows increases. As a result, most increases happen at renewal or during a month-to-month tenancy.
What happens if my landlord breaks the maximum rent increase allowed law?
You may be able to refuse the extra amount or recover rent you overpaid. For example, Washington’s attorney general can seek up to $7,500 per violation. Check with your court or a local legal-aid office before you withhold any rent.
