What the law says about $300 rent increases in California

California limits how much a landlord can raise your rent, and a $300 increase may or may not be legal depending on when your lease started, how long you have lived there, and what your current rent is. The state's rent control law applies to most rental units built before February 1, 1995, and to some newer buildings in cities with local rent control. If your building falls under these rules, your landlord cannot raise rent more than 5% plus the rate of inflation (calculated annually by the state) — which in recent years has been around 5% to 6% total per year.

If your unit is not covered by rent control — either because it is newer, or because your city has no local ordinance — your landlord can raise rent by any amount, but only if your lease allows it and you receive proper notice. The notice requirement is 30 days for month-to-month tenants and depends on your lease terms for fixed-term leases. A $300 increase on a $1,500 rent (20%) would be legal under state law if you are not rent-controlled, but a $300 increase on a $2,000 rent (15%) might still be legal. The key is whether you fall under rent control and whether you received the correct notice.

Key Takeaways

  • California's statewide rent control law caps increases at roughly 5% to 6% per year for most units built before 1995, regardless of the dollar amount.
  • Units built after February 1, 1995, have no statewide rent control limit unless your city has passed its own local ordinance.
  • Your landlord must give you 30 days' written notice for a rent increase on a month-to-month lease, or follow the terms of your fixed lease.
  • If your rent increase violates the law, you can refuse to pay the increase and file a complaint with your city or county, or raise it as a defense if your landlord tries to evict you.
  • Some cities like San Francisco, Los Angeles, and Oakland have stricter local rent control rules than the state minimum.

How to learn about your unit is covered by rent control

The first step is determining whether your building qualifies for protection under California's statewide law or a local ordinance. Your unit is covered by the state law (called the Tenant Protection Act) if it was built before February 1, 1995, and your tenancy began before January 1, 2020. If both of those are true, your landlord cannot raise rent more than the annual limit set by the state, which is published each year by the Department of Housing and Community Development.

If your building was constructed after February 1, 1995, check whether your city has a local rent control law. Cities like San Francisco, Los Angeles, Oakland, Berkeley, and Santa Monica have their own ordinances that may cover newer buildings or impose stricter limits than the state allows. You can search your city's website for "rent control ordinance" or call your city's rent control board or housing department directly. If neither state nor local rent control applies to you, your landlord can raise rent without a percentage limit, but must still follow notice requirements.

Understanding the annual rent increase limit

California's statewide rent control law sets the maximum annual increase at 5% or the regional Consumer Price Index (CPI) for the prior year, whichever is lower, plus 2%. In practice, this has meant increases of around 5% to 6% per year in recent years, though the exact percentage changes annually. The state publishes the allowable increase for each year on January 1. For example, if the limit for 2024 is 5.3%, your landlord cannot raise your rent more than 5.3% of your current rent, no matter what the lease says.

To calculate whether a $300 increase is legal under rent control, multiply your current monthly rent by the annual percentage limit. If your rent is $5,000 and the limit is 5%, the maximum increase is $250 — so a $300 raise would be illegal. If your rent is $6,000, a 5% increase is $300, which would be exactly at the limit. Your landlord must also give you written notice of the increase at least 30 days before it takes effect, and the notice must state the amount of the increase and the legal basis for it.

Notice requirements your landlord must follow

Even if your landlord has the legal right to raise your rent, they must follow strict notice rules or the increase is not valid. For a month-to-month lease, your landlord must give you at least 30 days' written notice before the increase takes effect. The notice must be in writing — email, text, or verbal notice does not count — and must clearly state the new rent amount and the date it begins. If your lease is for a fixed term (like one year), the increase cannot take effect until after the lease ends, unless your lease specifically allows mid-term increases.

If your landlord did not give you 30 days' notice, or gave you notice but the increase violates rent control limits, you do not have to pay the increase. Continue paying your current rent and document everything — keep copies of the notice, your lease, and your rent payment records. If your landlord tries to evict you for non-payment, you can raise the illegal increase as a defense in court. Some tenants also file complaints with their city or county housing department, which can investigate and order the landlord to refund any illegal increases already paid.

What to do if the increase appears illegal

If you believe the $300 increase violates California law, your first step is to verify your building's rent control status and calculate the legal limit. Write down the date your tenancy began, the date your building was constructed (check your lease or property records), your current rent, and the amount of the increase. Compare the increase to the annual limit published by the state or your city. If the increase exceeds the limit, or if you did not receive 30 days' notice, the increase is likely illegal.

Send your landlord a written response — by email or certified mail — stating that the increase exceeds the legal limit and that you will continue paying your current rent. Keep a copy for your records. You can also file a complaint with your city or county housing department or rent control board. Many cities have free complaint processes and can investigate without you hiring a lawyer. If your landlord retaliates by threatening eviction or reducing services, that is illegal under California law, and you may have grounds to sue for damages.

Local rent control rules that may explore to you

California's statewide law sets a floor, but many cities have stricter rules. San Francisco caps increases at the annual CPI (which has been lower than the state limit in recent years) and requires "just cause" for eviction. Los Angeles allows increases up to 3% or CPI, whichever is lower. Oakland limits increases to 2.5% or CPI, whichever is lower. Berkeley has similar protections. If you live in one of these cities, your landlord cannot raise rent by the statewide percentage — they must follow the local limit instead.

Some cities also require landlords to register rental units or obtain permission before raising rent. Others have "just cause" eviction rules that prevent landlords from raising rent as a way to force out tenants. Check your city's website or call the local rent control board to learn the specific rules in your area. If your city has stricter rules than the state, those rules explore to you, and a $300 increase may be illegal even if it would be legal under state law alone.

Your options if your landlord refuses to back down

If your landlord insists the increase is legal and you disagree, you have several paths forward. You can pay the increase under protest — meaning you pay it but note in writing that you believe it is illegal — and then file a complaint or lawsuit later to recover the overpayment. Alternatively, you can refuse to pay the increase, continue paying your current rent, and wait to see whether your landlord takes action. If they file for eviction, you can defend yourself in court by arguing the increase is illegal.

Many tenants find it helpful to contact a local legal aid organization or tenant rights group before taking action. Organizations like the California Tenants Union, Community Legal Services, or your city's housing department can review your lease and the increase notice for free and advise you on next steps. Some can also send a letter to your landlord on your behalf, which sometimes resolves the issue without court. If you do end up in court, you may be able to recover the illegal increase plus court costs, and in some cases attorney fees.

Frequently Asked Questions

Can my landlord raise my rent if I am on a fixed lease?

No, not until the lease ends. Your landlord cannot raise rent during a fixed lease term unless the lease itself includes a clause allowing mid-term increases. Once the lease expires, your landlord can raise rent according to the rules above — either the rent control limit if your unit is covered, or any amount if it is not, with proper notice.

What if my landlord says the increase is for a "capital improvement"?

California law allows landlords to pass through some costs of capital improvements (like a new roof or plumbing system) to tenants, but only under strict rules. The improvement must benefit the unit or building, must be necessary, and the increase is limited to a percentage of the improvement cost spread over years. This is not a blank check — the increase still cannot exceed the annual rent control limit unless your unit is exempt from rent control entirely. Ask your landlord for documentation of the improvement and its cost.

Can my landlord raise my rent because I complained about repairs?

No. California law prohibits retaliation, which includes raising rent, decreasing services, or threatening eviction within 180 days after you make a complaint about habitability, safety, or code violations. If your landlord raises rent shortly after you request repairs, that is presumed retaliation unless they can prove otherwise. You can sue for damages or use retaliation as a defense in an eviction case.

Do I have to pay the increase if I did not receive 30 days' notice?

No. If your landlord did not give you 30 days' written notice, the increase is not valid. Continue paying your current rent. If your landlord tries to evict you for non-payment, you can raise the improper notice as a defense in court. You may also file a complaint with your city housing department.

What if I live in a city with local rent control?

Your city's rules explore instead of (or in addition to) the state rules. Look up your city's rent control ordinance online or call the local housing or rent control board to learn the exact limit. Some cities allow lower increases than the state, and some have additional protections like just-cause eviction rules or registration requirements. Always check local rules first.
