The Increase You Didn't Take Is Gone

Here's how the last post in this series usually starts in real life. An owner has had a good tenant for four years, never raised the rent because the tenant was reliable and the unit was full, and now sits sixteen percent under market. They call to ask how to correct it.

The answer is that they mostly can't, and the reason is the part of AB 1482 nobody talks about.

Two rules, and most owners only know one

The cap. For covered tenancies, annual rent increases are limited to 5% plus the applicable regional Consumer Price Index (CPI), never exceeding 10% total, in any twelve-month period. No more than two increases in that window.

One local note that matters and that statewide guides get wrong for us: the CPI figure that applies here is the California statewide index, not the Los Angeles-Long Beach-Anaheim index that most write-ups reach for by default. Ventura County is not part of that metropolitan index. Confirm the current figure before you send a notice — it changes annually, and the wrong number in a notice is a defective notice.

The notice period, which is separate. Civil Code §827 governs how much warning you give: at least thirty days for an increase of ten percent or less cumulatively within twelve months, at least ninety days for more than ten percent. These are independent of the cap. An increase can be within the cap and still void because you gave the wrong notice.

Forfeiture is the expensive rule

Now the part that produced the phone call above.

There is no banking under AB 1482. An increase you were entitled to take and didn't is not stored for later. You cannot skip three years and then take three years' worth. Each twelve-month window offers what it offers, and when it closes, the unused portion is simply gone.

Which means the owner who was being generous wasn't deferring income. They were permanently forfeiting it, and compounding the forfeiture, because every year's allowable increase is calculated off a base that never moved.

The practical consequence for a below-market unit is that the gap essentially cannot be closed during the tenancy. Not slowly, not with a big correction, not at all. The only thing that resets the rent is a lawful vacancy — and by the time you want one, just cause applies.

I'd put this as plainly as I can: not raising the rent is a decision with a price, and the price is permanent. A modest annual increase that keeps pace is worth far more than the goodwill you're buying by skipping it.

If you're actually exempt, the calculation inverts

Everything above assumes a covered tenancy. If your property is a single-family home or condominium, you're a natural person owner, there's no accessory dwelling unit (ADU) on the parcel, and the exemption notice is in the lease, there's no cap on the amount — and, more importantly, no forfeiture rule.

That's the asymmetry worth understanding. The covered owner must take every increase, because what they skip is gone permanently. The exempt owner loses nothing by waiting, which means staying deliberately below market is available to them as a strategy rather than forced on them as a consequence.

There's a real case for using it. A tenant sitting modestly under market is a tenant who doesn't shop. Run the actual numbers on a turnover — vacancy weeks, make-ready, advertising, screening time, and the risk of a worse tenant — and it routinely exceeds several years of the gap you're declining to close. There's also how the number reads. An increase that looks like a routine annual adjustment gets paid without a conversation. One that looks like a correction to market prompts the tenant to find out what market actually is, and now they're looking at listings.

It's also the version that produces a specific kind of trouble. An exemption that removes the cap doesn't remove the retaliation rules, the notice rules, or the habitability obligations that a below-market tenancy tends to accumulate around. I've written about what that looked like on one of my own units in Why Being Exempt From Rent Control Made This Harder, and I'd rather send you there than summarize it.

Two things the exemption doesn't get you either way. §827 notice periods apply in full — exemption from the cap is not exemption from notice. And if you built an ADU on that lot, go back to Part 3 before assuming any of this reaches you.

Two rulebooks on one parcel

If you're renting both the main house and an ADU, check whether they're under the same rules before you send either notice.

New construction carries a rolling fifteen-year exemption measured from its own certificate of occupancy. A recently built ADU may be exempt from the cap. The older main house in front of it is not. There's no clear authority on which certificate controls the parcel as a whole, so plan conservatively — and don't assume that because one unit is exempt, both are.

And if you followed this series from Part 3: the day you moved out of the main house, the owner-occupied exemption ended. If your first increase after that move is calculated the way you calculated increases while you lived there, it's wrong.

Oxnard and Ojai are different

Both cities run their own rent stabilization ordinances with a four percent annual cap and one increase per twelve-month period. That's tighter than the state cap on both dimensions. Oxnard also runs a rental registry that reaches single-family homes and ADUs.

If your property is in either city, the state cap is not your ceiling. The local one is lower. Four percent flat, one increase a year, is more restrictive than 5% plus CPI on both dimensions — so work from the ordinance and treat the state rule as irrelevant to you.

Send the notice correctly

Get the arithmetic right, then get the service right. §827 has requirements for how a rent increase notice is delivered, and a notice served improperly doesn't take effect regardless of how correct the number is. If you use mail, build in the extra days. Keep proof of service with the tenant file.

And mind the retaliation window from Part 6. If your tenant recently complained about a repair, an entry, or a habitability issue, a rent increase inside that window is going to be read against that history — even when the timing is pure coincidence, which it often is. If an increase is due then, document why you're raising it and that the amount follows your normal practice. That's a five-minute note that answers a question you may be asked a year later.

The Backyard Landlord

The hardest rent increase in California to send is the one you hand to somebody whose car is parked next to yours.

You'll see them that afternoon. You know what they earn, roughly, because you've had a hundred small conversations. You know the daughter just started school nearby. And the increase you're entitled to take is a few dozen dollars a month — which feels, standing there, like a trivial amount to damage a good arrangement over.

So you skip it. And then you skip it again, because having skipped it once makes the next one harder.

Four years later you're materially below market on a unit you can't correct, in a tenancy you can't end without just cause, with a tenant who now reasonably believes the rent doesn't change — because for four years, it didn't.

The way out is to never be in that position. Set the expectation in the first lease: the rent is reviewed annually, adjusted by a stated method, with notice each spring. Then do it every year, on the same schedule, including the years you don't need the money and the years when everything is going well. A tenant who has received a small increase every April is not surprised by one. A tenant who has received none in four years experiences the first one as a message.

You aren't being generous by not raising the rent. You're deferring a conversation, at a cost you can't recover, with someone you're going to see tomorrow either way.
