California Rent Increases in 2026: What Orange County Landlords Need to Know

It’s that time of year again—when rental property owners sharpen their pencils, look at the market, and ask the question: “What should I charge for rent?”

For landlords in Orange County, that question comes with an important legal consideration this year. Effective August 1, 2026, through July 31, 2027, the maximum rent increase under California’s Tenant Protection Act is 8.7% for covered properties in Los Angeles and Orange counties.

That number is important, but there’s more to it than simply adding 8.7% to the current rent and sending out a notice.

How Is the 8.7% Rent Increase Calculated?

California’s Tenant Protection Act limits how much landlords can increase rent on certain properties covered by AB 1482.

For this upcoming rental year, the calculation is based on the applicable Consumer Price Index, or CPI. The CPI figure for this period is 3.7%.

California allows landlords to add 5 percentage points to that number:

3.7% CPI + 5% = 8.7% maximum increase

The state also has an overall cap of 10%, so even if inflation were significantly higher, the increase couldn't exceed that limit for properties covered by the law.

For example, if you're currently collecting $3,000 per month in rent, an 8.7% increase would work out to approximately $261 more per month, bringing the new rent to about $3,261.

But here's where I think landlords need to be careful.

The Maximum Increase Doesn't Mean You Should Automatically Raise Rent 8.7%

Just because the law allows an 8.7% increase doesn't necessarily mean that's the right move for your property.

I always tell property owners to look at the market first.

What are comparable properties renting for today? How long are similar rentals sitting vacant? Are tenants getting concessions? Has demand increased or decreased in your particular neighborhood?

There's a big difference between the legal maximum and the market-supported rent.

If comparable homes are renting for $3,100 and you're already at $3,200, raising the rent another 8.7% could put you well above the market. At that point, you may create a vacancy that costs you far more than the additional rent would have generated.

Remember, a vacant rental property isn't producing income.

If you lose a tenant and the property sits empty for a month or two while you search for someone new, you could easily give back a significant portion of the additional rent you were hoping to collect.

That's why I think landlords should look at this as a real estate market decision—not just a legal calculation.

Is Your Property Covered by AB 1482?

This is another important piece of the puzzle.

The 8.7% figure applies to properties that are actually covered by California's Tenant Protection Act. Not every rental property in California is subject to the same rules.

Before sending a rent-increase notice, make sure you understand whether your property falls under AB 1482 and whether there are any exemptions that apply.

You also need to consider whether your city or local jurisdiction has additional rent-control or tenant-protection regulations.

Local rules can sometimes impose lower limits or additional requirements, including specific notice requirements.

This is one of those situations where I wouldn't recommend guessing.

If you're unsure whether your property is covered, or you're not certain how much you can legally increase the rent, talk with a qualified California real estate attorney or property-management professional before sending the notice.

What Should Orange County Landlords Do Right Now?

If I owned a rental property today, I'd start with three things.

First, I'd look at the current rental market.

Don't rely on what your property rented for last year. Look at what comparable properties are actually renting for right now. Location, condition, size, amenities, parking, upgrades and even the time of year can make a big difference.

Second, I'd review the numbers.

Look at your mortgage, property taxes, insurance, HOA fees, maintenance and other expenses. Your costs may have changed considerably over the past year, and your rental income needs to make sense within the overall investment.

Third, I'd make sure I'm following the rules.

Confirm whether AB 1482 applies to the property, determine the allowable increase, and make sure the proper notice is provided. If local regulations apply, factor those in as well.

The goal isn't simply to collect the highest possible rent.

The goal is to maximize your investment while keeping a good tenant and staying within the law.

The Bottom Line for Orange County Landlords

The rental market continues to require landlords to be strategic.

For covered properties in Orange County, the maximum increase under California's Tenant Protection Act is 8.7% from August 1, 2026, through July 31, 2027, based on the current 3.7% CPI plus the 5% allowed under state law.

But I wouldn't treat that 8.7% number as an automatic recommendation.

Before increasing the rent, take a good look at what's happening around your property. Know what comparable rentals are getting, understand your expenses, consider the value of keeping your existing tenant, and make sure you understand the rules that apply to your specific property.

I've worked with a lot of homeowners and investors over the years, and one thing I've learned is that real estate rarely has a one-size-fits-all answer.

The right rent isn't necessarily the highest rent you can legally charge. It's the rent that makes sense for your property, your market and your investment strategy.

If you're an Orange County rental property owner and you're trying to figure out what your property should be renting for in today's market, I'd be happy to help you take a closer look at the numbers.
