Illegal Rent & Overcharges

There’s a Limit on What They Can Charge.

California caps how much and how often your rent can go up, bans a long list of “junk” fees, and lets you claw back money you were overcharged — sometimes three times over. If your rent or fees don’t add up, we can help you check the math and get it back.

The Basics

Your Rent Can’t Just Go Up Forever.

For most California rentals, the statewide Tenant Protection Act (AB 1482) caps annual rent increases at 5% plus inflation — and never more than 10% in a 12-month period, no matter how hot the market gets. There’s no exception for “rising costs” or improvements; the cap is the cap.

Landlords also can’t raise the rent more than twice a year, and the two raises together still can’t beat the yearly limit. And they can’t “bank” a skipped year and pile it on later.

Many landlords wrongly think single-family homes are automatically exempt. They’re not. A house or condo only escapes the cap if the owner is a real person (not a corporation, REIT, or corporate-backed LLC) and the lease contains an exact, legally required exemption notice. Missing that language? The cap applies — and any increase above it is unlawful.

Check the Fine Print

Is Your Rent Increase Even Legal?

Even an increase within the cap is void if it’s not delivered right. California (Civil Code §827) requires 30 days’ written notice for an increase of 10% or less, and 90 days’ notice for anything above 10%. Mailed instead of hand-delivered? Add five more days.

Here’s the trap landlords fall into: the 10% line is measured cumulatively over a rolling 12 months. A 6% bump in spring plus another 6% in fall is 12% — which means that second notice needed 90 days, not 30. Get it wrong, and the whole increase is unenforceable.

If you’re in a city with local rent control, the rules are usually even tighter — often a single, smaller increase per year, and the landlord must keep the unit properly registered. If you got a short notice or an over-cap hike, you generally don’t owe the unlawful part.

Recognize It

Fees They Can’t Charge You

As base rents got capped, some landlords turned to fees to make up the difference. California has been shutting those down one by one. These are the big ones.

Application-Fee Farming

Charging fees they can only cover their actual cost to run — capped at a modest state amount (around $65). They can’t charge at all if no unit is available, and must refund you if they never process your application.

Hidden Mandatory Fees

Advertising “$2,000” then tacking on required “valet trash,” “amenity,” or “tech” fees. California’s honest-pricing law says any mandatory fee must be in the advertised rent from day one.

Pay-by-Check & Notice Fees

Charging you a “convenience” fee to pay rent by check, or a “posting fee” to serve you a notice. Both are now flatly banned in California.

Punitive Late Fees

A flat $100 or compounding daily late charge. Late fees must reflect the landlord’s real, modest cost — not a penalty. Arbitrary fees are routinely thrown out as unenforceable.

Utility Markups

Billing you more than the actual water, trash, or gas bill, or charging for services you never received. A utility “fee” used as profit is an illegal rent increase in disguise.

“Catch-Up” Increases

Stacking on a big jump to make up for a year they didn’t raise the rent. “Banking” skipped increases isn’t allowed — the yearly cap is a hard ceiling every single year.

Two You May Not Know

Two Things Landlords Hope You Don’t Know.

Disasters freeze the rent. During a declared state of emergency — like California’s recent wildfires — Penal Code §396 makes it illegal to raise rent more than 10% above the pre-emergency price, even on a vacant unit and even on properties that are normally exempt. These caps are tied to specific declarations and time windows, so whether one covers your area right now depends on the current orders — but violating one can carry serious civil and even criminal exposure.

An illegal unit may mean no rent at all. If you’re living in an unpermitted unit — a converted garage, an illegal in-law — that lacks a certificate of occupancy, the lease may be legally void. Courts have refused to let landlords collect rent on units never cleared for living in, and in some cases tenants have recovered rent they already paid. If something feels off about your unit’s legality, it’s worth a closer look.

    Keep every notice and receipt

    Save your lease, every rent-increase notice, and proof of what you’ve paid. Your own records are the backbone of any overcharge claim — including the exact dates increases took effect.

  2. 02

    Check the math — and the fine print

    Add up your increases over the last 12 months against the cap, count the notice days, and look for the exact exemption language. A missing paragraph or a short notice can make the whole increase void.

  3. 03

    Don’t just stop paying

    Refusing to pay an illegal increase can trigger an eviction fight. It’s often safer to pay under written protest and seek a refund — get advice before you withhold anything.

  4. 04

    Use your rent board or small claims

    If you’re in a rent-controlled city, you can petition the local rent board to roll back an illegal increase. Otherwise, small claims is a fast, lawyer-free venue to recover overcharges and illegal fees.

  5. 05

    Talk to a tenant attorney

    Overcharge cases carry real teeth — a willful violation can mean triple damages plus your legal fees. We’ll check whether your rent and fees are lawful and pursue what you’re owed.

Why It’s Worth Fighting

What an Overcharge Claim Can Be Worth.

An illegal increase or fee is rarely “just” the overcharge — California stacks penalties and fee-shifting to make it costly for landlords who gamble. Depending on the facts, that may include:

Your Overcharge Refunded

Every dollar you paid above the legal limit — the unlawful part of a rent increase, plus any illegal fees collected along the way.

Up to Three Times the Amount

If the landlord charged over the cap willfully or in bad faith, the law allows treble damages — three times the overcharge — turning a small sum into a serious one.

A Rent Rollback

In rent-controlled cities, a rent board can order your rent rolled back to the lawful amount — and credit or refund what you overpaid.

Your Attorney’s Fees

The rent-cap law lets a winning tenant recover legal fees and costs — which is how we can take strong cases without charging you upfront.

Rent Back on an Illegal Unit

If your unit was never legal to rent, the landlord may have had no right to charge you — and you may be able to recover rent you already paid.

A Venue Built for This

Small claims court handles these disputes for amounts up to $12,500, with no lawyers in the room — an affordable path made for renters.

Sound Familiar?

Signs You’re Being Overcharged

  • A rent increase bigger than 10% in a single year
  • Two increases within twelve months that add up past the cap
  • Less than 30 (or 90) days’ notice of an increase
  • A “single-family exemption” with no notice in your lease
  • Mandatory fees never shown in the advertised rent
  • A fee just to pay by check or to be served a notice
  • A flat or daily late fee that feels like a punishment
  • A rent hike right after a wildfire or local emergency
Common Questions

Rent & Fees, Answered.

If you’re covered by the statewide Tenant Protection Act, no more than 5% plus local inflation — and never more than 10% — in any 12-month period. If you’re in a city with stricter rent control (like Los Angeles or San Francisco), the cap is often far lower and set by your local rent board.

Maybe. A house or condo is exempt only if the owner is a real person (not a corporation, REIT, or corporate-backed LLC) and the lease includes the exact legally required exemption notice. If that specific language isn’t in your lease, your home is treated as covered — and an increase above the cap is unlawful.

Probably not, unless your building is fully exempt from both local and statewide rent control (such as newer construction). And regardless, any increase over 10% requires at least 90 days’ written notice — 30 days if it’s 10% or less, plus 5 extra days if it was mailed. A short notice alone can make the increase unenforceable.

Only if they were built into the advertised rent. Under California’s honest-pricing law, a landlord can’t advertise “$2,000” and then spring a required $50 “valet trash” fee on you at signing. Mandatory fees hidden from the listed price are unlawful.

No. California now bans charging tenants any fee to pay rent or a deposit by check, and bans fees for serving or posting tenancy notices like a 3-day notice. Those “posting” and “convenience” charges are illegal.

You can pursue it back. You may file with your local rent board or sue in small claims (up to $12,500). And if a landlord willfully charged you over the legal rent cap, a court can award treble damages — three times the overcharge — plus your attorney’s fees. Don’t wait too long, though; deadlines apply.
