Raising rent should be a simple business decision — your costs go up, market rates shift, and you adjust accordingly. But in California, it’s not quite that simple. Between the statewide rent cap and the notice requirements that come with it, there’s a specific process you need to follow, and getting it wrong can mean your rent increase doesn’t legally hold up, or worse, gets challenged by a tenant who knows their rights.
Whether you’re managing a single rental in Bakersfield or a small portfolio across the state, here’s exactly what you need to know about how much you can raise rent in 2026 and how to do it correctly.
The Statewide Rent Cap Under AB 1482
For most residential rentals that aren’t otherwise exempt, California’s Tenant Protection Act (AB 1482) limits annual rent increases to 5% plus the local rate of inflation, with an absolute cap of 10% total — whichever number is lower. The inflation figure used is based on the regional Consumer Price Index (CPI), which means the exact allowable percentage can shift slightly from year to year and varies a bit by region.
This cap applies to the total increase within any rolling 12-month period. You can’t raise rent 5% in January and another 5% in July and call it compliant — the cumulative increase across any 12-month window still has to stay within the legal limit.
How to Find the Current Allowable Percentage
Because the cap is tied to inflation, it’s not a fixed number you can memorize once and use forever. Each year, you’ll need to check the most recent CPI data for your region (Kern County and the broader Bakersfield area typically fall under a specific regional index) to calculate the exact maximum increase allowed. Many property management companies and tenant rights organizations publish updated tables each year specifically to help landlords get this number right.
Which Properties Are Exempt From the Cap?
Not every rental in California is subject to AB 1482’s rent cap. Common exemptions include:
- Single-family homes and condos, as long as the owner isn’t a corporation, REIT, or certain LLCs, and the required exemption notice was provided to the tenant
- Properties with a certificate of occupancy issued within the last 15 years
- Housing already covered by a local rent control ordinance that’s at least as protective
- Deed-restricted affordable housing
If your property qualifies for an exemption, you’re not bound by the statewide percentage cap — though you’ll still need to follow standard notice requirements for any rent increase, and local market norms (along with basic fairness) usually still apply if you want to retain good tenants.
Notice Requirements for Rent Increases
Even when a rent increase falls within the legal cap, you still have to give tenants proper advance notice. The required notice period in California depends on the size of the increase:
- 10% or less within a 12-month period: at least 30 days’ written notice
- More than 10% within a 12-month period (applicable to exempt properties not bound by the AB 1482 cap): at least 90 days’ written notice
This notice has to be delivered properly — typically in writing, either hand-delivered, mailed, or posted and mailed if direct delivery isn’t possible — and it should clearly state the new rent amount and the date it takes effect.
How Often Can You Raise Rent?
For month-to-month tenancies, you’re generally allowed to raise rent once every 12 months, assuming you stay within the applicable cap and follow notice requirements. For fixed-term leases, you typically can’t raise rent at all until the lease term ends, unless the lease itself specifically allows for a mid-term increase under certain conditions (which is uncommon and usually not advisable from a tenant-relations standpoint anyway).
What Happens If You Raise Rent Above the Legal Limit?
If you raise rent beyond what AB 1482 allows on a covered property, a tenant can challenge the increase, and you may be required to roll the rent back to the legal amount. In some cases, tenants who paid an illegally high rent increase may be entitled to recover the overpaid amount. Repeated or willful violations can also expose you to penalties under California’s broader tenant protection statutes.
This is one of those situations where a simple miscalculation — using last year’s CPI figure instead of the current one, for example — can create real financial and legal exposure. Double-checking the current allowable percentage before sending any increase notice is worth the few minutes it takes.
Balancing Compliance With Smart Business Decisions
Even when you’re legally allowed to raise rent up to the maximum cap, that doesn’t always mean you should. Pushing rent to the absolute legal limit every single year can increase tenant turnover, and turnover comes with its own costs — vacancy periods, marketing, cleaning, and the risk of a worse tenant moving in next.
Many experienced Bakersfield landlords find that a more measured approach — smaller, predictable annual increases that track closer to actual cost increases rather than the legal maximum — tends to keep good tenants in place longer, which often nets out to better long-term returns than maximizing every increase.
A Quick Compliance Checklist Before You Send a Rent Increase Notice
- Confirm whether your property is exempt from AB 1482 or subject to the statewide cap
- Check the current year’s regional CPI figure to calculate the maximum allowable increase
- Calculate the increase based on the rolling 12-month period, not just since the last increase
- Determine the correct notice period (30 or 90 days) based on the increase size
- Deliver the notice in writing through a legally acceptable method
- Keep a dated copy of the notice and proof of delivery on file
Final Thoughts
Rent increases in California come with more structure than landlords in many other states are used to, but once you understand the framework, it’s a fairly predictable process: check your exemption status, calculate the current allowable percentage, give proper notice, and document everything.
If keeping track of changing CPI figures and notice requirements every year feels like one more thing on an already long list, a local property management company can handle the entire rent increase process for you — making sure every notice is compliant, timely, and properly documented, while you focus on the bigger picture of your investment.
