A 20% Rent Hike May Not Be Legal
Getting a notice that your rent is jumping hundreds of dollars is frightening — but in much of California there's a legal ceiling on how far it can go in a year. The same law that requires just cause to evict also caps rent increases. Ava asked attorney Michael Benavides how the cap works.
Ava Asks, Michael Answers — Rent Caps, Plain English
Ava:
Is there a limit on how much my rent can go up?
Michael, Esq.:
In covered housing, yes. Under the Tenant Protection Act — Civil Code section 1947.12 — annual rent increases are capped at 5% plus the local rate of inflation (CPI), or 10%, whichever is lower. So the ceiling is never more than 10% in a 12-month period.
Ava:
Can they raise it twice in one year?
Michael, Esq.:
They can raise rent no more than twice in any 12-month period, and the two increases combined still can't exceed the 5%-plus-CPI cap. It's a total annual ceiling, not a per-increase one.
Ava:
Which homes are covered?
Michael, Esq.:
Most rental units more than 15 years old. Housing under a stronger local rent-control ordinance follows that local law instead. And some units are exempt from AB 1482.
Ava:
What's exempt?
Michael, Esq.:
Common exemptions include most single-family homes and condos owned by an individual (not a corporation or REIT) when the required notice is in the lease, owner-occupied duplexes, and newer construction under 15 years old. Corporate-owned single-family homes are generally covered.
Ava:
The cap moves with inflation — how do I know my number?
Michael, Esq.:
The CPI piece is tied to your region and changes yearly, so the exact percentage varies by area and date. The key rule is simple: whatever the formula produces, it can never exceed 10% in a year.
Ava:
My landlord raised it more than that. Now what?
Michael, Esq.:
If your unit is covered, an increase above the cap is unenforceable as to the excess. You generally owe only the lawful amount, and an overcharge can be challenged — sometimes with penalties, depending on the circumstances.
Ava:
Does this expire?
Michael, Esq.:
The Tenant Protection Act runs through January 1, 2030 unless the Legislature extends it. Until then, the rent cap and just-cause protections apply to covered units statewide.
What to Do
In covered California housing, your rent can't rise more than 5% plus local inflation, capped at 10% a year, with no more than two increases in 12 months. Check whether your unit is covered, compare the notice to the cap, and don't just pay an illegal increase. A free Law Desk consult can confirm your ceiling and challenge an overcharge.
