Rent increase at lease renewal: how much notice is required?

The short answer

A landlord can't usually raise the rent with a phone call and a new number on the next invoice. Most places set three things: how much written notice you get, how often rent can go up, and sometimes how much it can rise. The rules also depend on whether you have a fixed-term lease (with an end date) or a periodic one (month to month).

Your lease is the first place to look. It may say when rent can change, how you'll be told, and what happens when the term ends. But the law where you live can override a lease term that gives you less than the legal minimum.

Fixed-term leases: rent is usually locked in

During a fixed term, the rent in the lease generally applies until the end date. California's Department of Real Estate (DRE) puts it plainly: in a fixed-term agreement, the landlord can't raise the rent during the term "unless the rental agreement permits rent increases." New South Wales has a similar rule for fixed terms of less than two years that began before 13 December 2024: if the agreement doesn't set out the increase amount or an exact way to calculate it, the rent can't go up during the term.

So the clause to look for reads something like this:

Sample clause (fictional): "Rent will increase by 3% on the first anniversary of the start date."

If your lease has a clause like this, the increase is part of the deal you signed. If it has nothing, the increase usually comes at renewal, when the landlord can offer a new term at a new rent.

What happens at renewal

At the end of a fixed term, one of three things usually happens:

1. You sign a new lease at a new rent. The notice rules for your area still apply to the increase.

2. The lease renews automatically for another term, often at a rent stated in the lease or a notice. In New York, the state AG's tenants' rights guide says a landlord using an automatic renewal clause must remind the tenant of it 15 to 30 days before the tenant's deadline to say they won't renew.

3. The tenancy rolls onto month-to-month. In Ontario and British Columbia, a fixed term that ends without a new agreement generally continues as a monthly tenancy, and the normal rent-increase rules then apply.

Notice rules: examples from official sources

These are examples, not a complete list. Rules also change, so check your own state, province or territory before relying on a date.

United States

• California. For month-to-month tenancies, the DRE guide says properties covered by the state Tenant Protection Act need 30 days' written notice before an increase. For properties outside the state limit and any local ordinance, the notice is 30 days for an increase of 10% or less and 90 days for more than 10%. Covered properties are also capped at 5% plus inflation, or 10%, whichever is lower, in a 12-month period. Mailed notices add extra days.

• New York. For apartments that aren't rent regulated, the state AG's guide says an increase of more than 5% needs advance written notice: 30 days if you've lived there under a year, 60 days for one to two years, and 90 days for two years or more. The guide also says a landlord of a non-regulated apartment doesn't have to renew the lease.

Many cities have their own rent rules on top of state law. Your state AG's office or your city's housing department can tell you what applies.

Canada (outside Quebec)

• Ontario. The Landlord and Tenant Board (LTB) says a landlord must give at least 90 days' written notice, on an official form, of any increase. Rent can generally go up once every 12 months. The province sets a yearly rent increase guideline. The LTB explains which units it covers.

• British Columbia. The provincial government says landlords must give three full months' notice on the official Notice of Rent Increase form (RTB-7). Rent can go up only once every 12 months and within the yearly limit, which is 2.3% for 2026. If proper notice wasn't given, you don't have to pay the increase.

Australia

• New South Wales. The NSW Government says the landlord or agent must give written notice at least 60 days before the increase. No increase is allowed in the first 12 months of a tenancy, and there must be at least 12 months between increases. If you think an increase is excessive, you can apply to the NSW Civil and Administrative Tribunal (NCAT) within 30 days of getting the notice.

• Victoria. Consumer Affairs Victoria says that from 25 November 2025 the minimum notice rose from 60 to 90 days. In most cases rent can't go up more than once every 12 months, and the landlord must use the correct form.

Other states, territories and provinces have their own rules. Look for your local tenancy authority or tribunal.

How to check a rent increase notice

When the notice arrives, read it against your lease and your local rules. Work through this list:

1. Is it in writing? Most of the rules above require written notice. A text or a verbal mention may not count. Check what your area accepts.

2. Is the timing right? Count the days from when you received it, or from the mailing date if your area adds days for mail, to the date the new rent starts.

3. Is it on the right form? Ontario, British Columbia and Victoria all use official forms.

4. When was the last increase? Many places allow only one increase every 12 months. Find the date of your last increase or your move-in date.

5. Does your lease allow a mid-term increase? If you're still inside a fixed term and the lease is silent, ask the landlord which clause they're relying on.

6. What's the new amount and start date? NSW, for example, requires the notice to state the new rent, not just the increase.

7. Is there a cap? Some places limit the size of the increase, and many don't. Check with your local body.

Questions to ask your landlord

If something doesn't add up, ask in writing and keep a copy:

• Which clause of the lease allows this increase?

• What date was the last rent increase on this unit?

• Is this increase subject to any local or state limit?

• If I renew, will the rent change again during the new term?

• What happens if I don't sign the renewal: does the tenancy continue month to month?

Asking isn't confrontational. It creates a record and often clears up a simple mistake, like a notice dated too late.

Before you sign a renewal

A renewal is a new agreement, so read it like one. Landlords sometimes update fees, pet rules, parking or the notice you must give to leave. Compare it clause by clause with your current lease.
