What the law allows depends on where you live and what your lease says

Whether your landlord can raise your rent $300 depends on three things: your state or city's rent control laws, what your lease says, and when your lease ends. In most of the United States, landlords can raise rent by any amount they choose when a lease renews — but some states and cities have caps. A few places ban rent increases altogether for certain tenants. The $300 figure matters only if it pushes you past a legal limit in your area.

If you are month-to-month, the rules are stricter in some places and looser in others. Some states require 30 or 60 days' notice before any increase takes effect. Others let landlords raise rent with just the notice period your lease specifies. A few cities require landlords to show "just cause" — a real reason beyond "I want more money" — before raising rent at all.

The first step is to know which rules explore to you. That means checking your state law, your city or county law, and your lease itself. A $300 raise might be legal where you live, or it might violate a cap, or it might be illegal without just cause. You cannot know until you look.

Key Takeaways

  • Most states allow landlords to raise rent by any amount when a lease renews, but some states and cities cap increases at a percentage or dollar amount each year.
  • A few cities require landlords to show just cause — a legitimate reason beyond profit — before raising rent, and a $300 increase without cause would be illegal there.
  • Month-to-month tenants usually get 30 or 60 days' notice before a rent increase takes effect, depending on your state law.
  • Your lease itself may limit how much rent can be raised or when, so read it carefully before assuming the increase is legal.
  • Rent control laws vary by state and city, so you need to check the rules where you live, not assume they match another state.

States and cities with rent increase caps or restrictions

California caps annual rent increases at 5 percent plus inflation (a combined limit that usually comes to 8 to 10 percent per year), but only for tenancies that started before March 2025 and only if the unit is not exempt. New construction, single-family homes, and some other properties are exempt. A $300 raise on a $1,500 rent (20 percent) would violate the cap; on a $3,000 rent (10 percent) it might not, depending on the inflation rate that year.

New York has a Rent Guidelines Board that sets allowable increases each year — recently in the range of 0 to 3 percent for one-year leases. A $300 raise would almost certainly exceed that cap. However, the cap applies only to rent-stabilized apartments, which are mostly in New York City and mostly older buildings. Market-rate apartments have no cap.

Oregon allows annual increases of up to 7 percent plus inflation (usually 9 to 10 percent total), but landlords must give 90 days' notice. Increases above that threshold are illegal. Some Oregon cities have stricter rules.

Washington state allows increases of up to 7 percent plus inflation annually, with 60 days' notice required. Increases above that are illegal.

Colorado, Connecticut, Delaware, Florida, Illinois, Maine, Maryland, Minnesota, Mississippi, Missouri, Nevada, New Hampshire, New Mexico, Ohio, Rhode Island, Tennessee, Vermont, and Virginia have some form of rent control or just-cause protections, though the rules vary widely. Some cap increases; others require just cause but allow any amount; others explore only to certain cities or property types. You must check your specific city and state.

Most other states have no statewide rent control. Landlords can raise rent by any amount when a lease renews. However, some individual cities in those states have local rent control — for example, San Francisco and Oakland in California, and some cities in Massachusetts and New Jersey. Check your city's website or housing authority.

What "just cause" means and why it matters

In cities with just-cause rules, a landlord cannot raise rent straightforward because they want more money. They must have a legitimate reason: the tenant is not paying rent, the tenant is breaking the lease, the landlord is moving into the unit themselves, the building is being demolished, or the landlord is converting the unit to a condo or short-term rental. A $300 raise with no reason other than profit is illegal in those places.

Just-cause cities include San Francisco, Oakland, Los Angeles, and several others in California; Minneapolis and St. Paul in Minnesota; and parts of New Jersey, Massachusetts, and other states. The list changes, so check your city's housing authority or tenant rights organization.

If your landlord raises rent without just cause in a just-cause city, you can file a complaint with your local housing authority or tenant board. Some cities allow you to sue for damages or to stay in the unit at the old rent. The process and remedies vary by location.

Month-to-month tenants and notice requirements

If you are on a month-to-month lease, your landlord usually must give you written notice before a rent increase takes effect. The notice period is set by state law, not by the landlord. Most states require 30 days' notice; some require 60 or 90 days. A few states allow notice equal to the rent payment period — so if you pay monthly, 30 days is enough.

Check your state's landlord-tenant law to find the exact notice period. If your landlord gives you less notice than the law requires, the increase may not be valid. Some states say the increase does not take effect until the next rent period after the notice period ends.

Even with proper notice, the increase must still comply with any rent cap in your area. A $300 raise is not legal just because the notice was given on time.

What your lease says and when it ends

If you have a fixed-term lease — for example, a one-year lease that ends on June 30 — your landlord cannot raise rent until that lease ends. Any increase they propose before the lease ends is not valid. When the lease ends, your landlord can offer a new lease at a higher rent, and you can choose to sign it or move out.

Some leases include a clause that limits how much rent can be raised. For example, a lease might say "rent increases are capped at 3 percent per year." If your lease has such a clause, a $300 raise that exceeds that cap is a breach of the lease, and you can refuse to pay it.

Read your lease carefully. Look for any language about rent increases, renewal terms, or caps. If you cannot find the lease, ask your landlord for a copy. They are required to provide one in most states.

How to find out what the law is where you live

Start with your state's attorney general website or your state legislature's website. Search for "landlord tenant law" or "rent control." Most states post their laws online for free.

Next, check your city or county. Many cities have housing authorities or tenant rights offices that publish summaries of local rules. A quick search for "[your city] rent control" or "[your city] rent increase" usually finds the answer.

If you find conflicting information, call your local housing authority or a tenant rights organization in your area. Many offer free phone consultations. The National Low Income Housing Coalition and the National Housing Law Project both maintain lists of local organizations by state.

Write down the specific law or rule that applies to you — the statute number, the city ordinance, or the rule name. If your landlord raises rent illegally, you will need to cite the exact rule to challenge it.

What to do if the raise seems illegal

First, get the notice in writing. Your landlord must give you written notice of a rent increase; a verbal announcement is not enough in most states. If they have not given you written notice, ask for it in writing yourself — send an email saying "I understood you to say my rent is increasing to $[amount] on [date]. Please confirm this in writing."

Next, check the law. Use the steps above to find out whether the increase is legal in your area. If it appears to violate a rent cap or just-cause rule, document that — write down the statute number and the rule.

Then, respond to your landlord in writing. Send an email or letter saying something like: "I received your notice of rent increase to $[amount]. Under [state/city law], rent increases are limited to [cap or rule]. This increase exceeds that limit and is not valid. I will continue paying $[current rent] until a legal increase is proposed." Keep a copy for yourself.

If your landlord tries to evict you for not paying the illegal increase, you can defend yourself in court by showing that the increase was illegal. Many states allow tenants to sue landlords for damages if they try to enforce an illegal increase. Some allow tenants to recover attorney fees.

If you are unsure whether the increase is legal, contact a local tenant rights organization or legal aid office before responding. Many offer free consultations.

Frequently Asked Questions

Can my landlord raise my rent if I am in the middle of a lease?

No. A fixed-term lease locks in the rent for the entire term. Your landlord cannot raise rent until the lease ends. If your lease says rent can be raised mid-term, that clause must comply with any rent control law in your area.

What if my landlord says the increase is for "maintenance" or "property taxes"?

The reason does not matter in most states. Landlords can raise rent for any reason or no reason when a lease renews, unless you live in a just-cause city. In just-cause cities, maintenance and property taxes are not valid reasons to raise rent — only specific hardships like the ones listed above are allowed.

Can I refuse to pay the increase and stay in the apartment?

Only if the increase is illegal under your state or city law. If it is legal, refusing to pay gives your landlord grounds to evict you. If it is illegal, you can refuse and defend an eviction in court, but you should get legal information first and respond in writing to protect yourself.

Do I have to sign a new lease if my landlord raises the rent?

If your current lease is ending, your landlord can offer a new lease at a higher rent. You can sign it or move out. You cannot stay in the apartment at the old rent if you refuse to sign. However, if the new rent violates a rent cap or just-cause rule, you can refuse the increase and stay at the old rent.

What if I cannot afford the new rent?

If the increase is legal, your options are to negotiate with your landlord, look for a cheaper apartment, or explore rental information programs in your area. If the increase is illegal, challenge it using the steps above. Contact a local tenant rights organization for help with either path.
