California's Rent Cap Is 8.8% Right Now — And Most Landlords Either Don't Know It or Don't Trust It

What AB 1482 actually allows this year, why the cap number matters for your renewal strategy, and the one mistake that makes the allowable increase irrelevant.

There's a persistent frustration among California landlords about AB 1482 — the statewide rent control law that has been in effect since January 2020. Some landlords think the cap is fixed at 5%. Some think it's 5% plus CPI but aren't sure which CPI or how to calculate it. Some have just given up trying to follow it and default to small increases that leave money on the table, figuring that's safer than getting it wrong.

Here's the current number: for the Bay Area CPI region — which applies to the Central Valley and Tri-Valley under the current CPI classification — the AB 1482 maximum allowable rent increase is 8.8% annually, effective August 1, 2026.

That's the number. It's the highest it's been in years, and it's in effect right now.

How the Cap Works

AB 1482 sets a maximum annual rent increase for covered units at 5% plus local CPI — but not to exceed 10% total, and not lower than 5%. The CPI component floats with the official Consumer Price Index figures published for each region.

For Bay Area CPI region landlords, the math came out to 8.8% this cycle. That means for a unit covered under AB 1482, you can raise rent by up to 8.8% in a single annual increase without violating state law.

Two important clarifications. First, this cap is per 12-month period — it's not cumulative, and you cannot bank unused increases from prior years and apply them all at once. One increase per year, up to the cap. Second, the 8.8% number reflects what the law permits, not what the market will support. These are different questions and the distinction matters for how you use the information.

Who Is Actually Covered

Before you apply the cap or build a renewal strategy around it, you need to confirm whether your unit is actually subject to AB 1482. Not all California rentals are.

AB 1482 does not apply to:

Single-family homes and condos where the owner has provided proper written notice of the exemption to the tenant. This is the piece many individual landlords miss — the exemption exists, but it only works if you've served the required notice. If you own a single-family rental and have never provided written AB 1482 exemption notice to your tenant, your property may be treated as covered by default, regardless of the unit type.

Properties built within the last 15 years are also exempt, which covers a significant portion of newer Central Valley and Tri-Valley construction. The 15-year window rolls forward, so the cutoff date changes each year.

Duplexes where the owner occupies one unit fall outside AB 1482 as well.

If you're uncertain whether your unit is covered, that question is worth resolving with a real estate attorney or a property manager before your next renewal cycle — not after you've already issued the notice.

The Exemption Notice Most Landlords Forget

If you own a single-family home or condo and want to be clear of AB 1482, the law requires that you serve tenants with specific written notice informing them that the unit is exempt from AB 1482's rent increase and just cause eviction protections. Without that notice, a court may treat your unit as covered.

This doesn't require legal help to execute, but it does require that it's actually done — and done in writing, provided to the tenant in a way you can document. If you've acquired a single-family rental in the last few years and have never thought about this, it's worth checking whether the exemption notice is in the file.

For covered units, the notice issue runs in the other direction: rent increases above the AB 1482 cap, or second increases within a 12-month period, can expose a landlord to liability even if the dollar amount seems minor. The mechanics of the law matter more than the intent.

The Real Strategic Question

The AB 1482 cap tells you the legal ceiling. It doesn't tell you what to charge.

At 8.8%, a tenant paying $2,200 per month could legally be raised to $2,393. On a $3,500 unit, the cap gets you to $3,808. Those are real numbers, and in a market where vacancy is a cost and tenant turnover in the Central Valley can run $2,000–$4,000+ when you factor in lost rent, prep costs, and your time, the decision isn't simply "how much can I raise?"

The better question is: what does this tenant, in this unit, at this time, justify?

A long-term tenant in a well-maintained unit who pays on time and causes no issues has a replacement cost that most landlords underestimate. An 8.8% increase on a $2,000 unit is $176 per month. If that increase triggers a vacancy, you're looking at at least two months of lost rent plus make-ready costs before you see a new tenant paying market rate. The math frequently doesn't work in favor of maximizing the increase.

That's not an argument against raising rent. It's an argument for being deliberate about it — understanding what the market actually rents for in your area right now, what your unit's condition supports, and what the relationship with your current tenant is worth before you decide how much of the legal allowance to use.

What the Market Is Actually Doing

In the Central Valley — Tracy, Manteca, Stockton, Lodi, Lathrop — the rental market in fall 2026 is tighter than it was a year ago. Rising home prices and mortgage rates that remain above 7% have kept would-be buyers renting longer, which has kept vacancy rates low across the region. That underlying demand means landlords in the Central Valley are generally in a position to increase rents without significant vacancy risk at moderate increases.

In the Tri-Valley, the picture is more varied. Pleasanton is running strong — average rents around $2,957/month, up 3.28% year over year. Livermore is steady at roughly $2,653/month with modest growth. Dublin is the outlier, absorbing a wave of new multifamily supply that has pushed average rents down about 9% year over year. Dublin landlords competing with new-construction apartment complexes offering concessions have less pricing power right now than landlords in most of the rest of the region.

The 8.8% cap is the same across all of these markets. How much of it you can actually use depends on what your local submarket will support.

One More Thing About AB 1482: Just Cause Eviction

AB 1482 isn't only a rent cap. For covered units, it also imposes just cause eviction requirements — meaning you need a qualifying legal reason to terminate a tenancy, not simply a desire to re-rent the unit at a higher rate or to a different tenant.

This is the part of the law that surprises landlords who focus entirely on the rent cap side. If your unit is covered under AB 1482, you cannot terminate a month-to-month tenancy without just cause — even if the lease term has ended, even if you'd prefer a different tenant. The just cause provisions are a significant constraint on landlord flexibility that exists alongside the rent cap, and understanding them is part of operating a covered unit correctly.

If you've been managing a covered rental without factoring in just cause requirements, this is worth a direct conversation with a property manager or attorney before you have a situation where it matters.

The Straight Take

AB 1482 gives Central Valley and Tri-Valley landlords up to 8.8% in annual increases right now. That's meaningful pricing power, and landlords who've been leaving it on the table out of uncertainty about the rules now have the number.

Use it deliberately. Know whether your unit is covered. Get the exemption notice in place if you're exempt and haven't served it. Don't raise rent because the law says you can — raise it because your market analysis and your tenant relationship support it. And don't ignore the just cause side of the law while focusing on the cap.

The rules are designed to be confusing enough that many landlords either over-comply (charging less than they're allowed) or under-comply (charging more without proper notice). Neither position helps you.
