How Much Can My Landlord Raise Rent in Los Angeles in 2026?

If you rent in Los Angeles and just got a notice that your rent is going up, the first question is almost never “is this legal?” in the abstract — it’s “which set of rules covers my apartment?” That matters enormously, because the same building on the same street can be capped at under 2% or as high as 8%+ depending on where it sits and when it was built.

There are three separate rent-increase regimes that can apply to a Los Angeles rental in 2026: the City of Los Angeles Rent Stabilization Ordinance (RSO), the LA County Rent Stabilization and Tenant Protections Ordinance (RSTPO) for unincorporated areas, and California’s statewide AB 1482 (the Tenant Protection Act). Only one applies to your unit at a time, and figuring out which is the single most important step. This guide walks through all three, how to identify yours, the current allowed percentages, the notice your landlord must give under Civil Code § 827, and your options if the increase is illegal.

This is general educational information, not legal advice. Always confirm current figures on the official pages linked below, since the CPI-based caps change every year.

The three rent-increase regimes in Los Angeles

Think of these as three layers. The strongest tenant protections come from local rent control (the City RSO or the County RSTPO). Where no local rent-control ordinance applies, the statewide AB 1482 cap usually still does. And a small number of units are exempt from all of them.

• LA City RSO (LAMC § 151.00 et seq.): Generally covers rental units in buildings with two or more units built on or before October 1, 1978, located inside the City of Los Angeles. The RSO sets a specific annual percentage published each year by the LA Housing Department (LAHD).
• LA County RSTPO: Covers rental units in the unincorporated areas of LA County only — places like East LA, Altadena, Ladera Heights, View Park–Windsor Hills, and Marina del Rey that are not inside any city. It is administered by the County Department of Consumer and Business Affairs (DCBA).
• AB 1482 (Civil Code § 1947.12): The statewide backstop. It caps annual increases at the lower of 5% plus regional CPI, or 10%, and applies to most rentals across California that are not already covered by a stronger local ordinance and are not otherwise exempt.

A unit covered by the City RSO or County RSTPO follows that local cap, not AB 1482. AB 1482 fills the gap for units in incorporated cities (or newer City-of-LA buildings) that have no local rent control.

How to tell which one applies to your address

Work through these questions in order:

• 1. Is your address inside the City of Los Angeles, another city, or an unincorporated county area? This is the key fork. “Los Angeles” on your mail does not always mean you’re inside the City — many neighborhoods with an L.A. mailing address are actually unincorporated county land. You can confirm your jurisdiction using the LA County registrar’s district locator or the City’s Neighborhood Info / ZIMAS parcel lookup.
• 2. If you’re in the City of LA: Check whether the building has 2+ units and a certificate of occupancy dated on or before October 1, 1978. If yes, it’s almost certainly RSO. Single-family homes and condos are generally not RSO, and newer buildings are exempt from RSO (though AB 1482 may still apply).
• 3. If you’re in an unincorporated area: The County RSTPO likely governs your increase, with AB 1482 as an additional layer of just-cause and other protections.
• 4. If neither local ordinance applies: AB 1482 probably does — unless your unit is specifically exempt (see below).

Not sure who your landlord even is or when the building went up? Our Who Owns My Building? tool can help you pull ownership and property records, which also reveal the year built — the fact that decides RSO coverage.

Common exemptions from AB 1482: single-family homes and condos when the owner is not a corporation, REIT, or an LLC with a corporate member (and the required written exemption notice was given); housing with a certificate of occupancy issued within the last 15 years (a rolling window, so a 2011 building loses its exemption in 2026); and units already covered by a stronger local ordinance. If your landlord claims a single-family exemption, they must have served you the specific statutory notice — no notice, no exemption.

The current allowed percentages for 2026

LA City RSO

The RSO allowable increase is a CPI-based percentage published by LAHD each year, effective July 1. By ordinance it floats with the Consumer Price Index but is banded — it cannot be lower than 3% or higher than 8% in a regulatory year. If the landlord pays for the tenant’s gas, they may add 1%; if they pay for electricity, they may add another 1% (so up to 8%+2% in the rare maximum case). A landlord may take only one RSO increase in a 12-month period.

Because this number is reset annually, do not rely on a figure from a blog — confirm the exact current percentage directly on LAHD’s RSO page before you accept or dispute an increase. In recent regulatory years the published figure has landed at the low end of the band (in the 3–4% range), reflecting how the RSO CPI formula is calculated.

LA County RSTPO (unincorporated areas)

For the regulatory year running July 1, 2026 through June 30, 2027, DCBA has published these allowable increase figures for covered units in unincorporated LA County:

• 1.919% — the standard allowable increase for fully covered units (the ordinance limits increases to 60% of the change in CPI, capped at a maximum of 3%);
• 2.919% and 3.919% — higher brackets that can apply in specific circumstances (for example depending on unit category or landlord-paid utilities).

Which bracket applies to your unit depends on the details, so check your situation against the County’s current chart at the LA County DCBA Rent Stabilization Program. As with the City, only one increase is allowed per 12 months.

AB 1482 statewide cap

For units governed by AB 1482 rather than local rent control, the cap is the lower of 5% + regional CPI, or 10%, per Civil Code § 1947.12. For the Los Angeles–Long Beach–Anaheim metropolitan area, that has worked out to approximately:

• 8.0% for increases effective August 1, 2025 through July 31, 2026;
• 8.7% for increases effective August 1, 2026 through July 31, 2027.

AB 1482 allows up to two increases in a 12-month period, but their combined total still cannot exceed the annual cap. Because the regional CPI component is republished annually, confirm the current maximum for your metro before relying on it. See Civil Code § 1947.12.

Notice periods under Civil Code § 827

Separate from how much your landlord can raise the rent is how much warning they must give. California Civil Code § 827 sets the notice rules for month-to-month tenancies:

• 30 days’ written notice if the cumulative rent increase over the previous 12 months is 10% or less;
• 90 days’ written notice if the cumulative increase over 12 months is more than 10%;
• Add 5 days when the notice is served by mail rather than handed to you in person.

Since RSO and RSTPO increases are capped well under 10%, those tenants will almost always get 30 days (35 by mail). AB 1482 tenants facing an increase near the 8–10% cap will typically be entitled to 90 days’ notice. A rent increase served with the wrong notice period is not yet effective — the clock hasn’t legally run. Read the statute at Civil Code § 827.

What to do about an illegal rent increase

If the increase exceeds your cap, skips required notice, or is a second increase in a year that isn’t allowed, you have options. An over-the-cap increase is generally void as to the excess — you owe the legal amount, not the demanded amount.

• Confirm the correct cap first using the official page for your regime (linked above). Write down the year built, your jurisdiction, and the exact percentage you should have received.
• Notify your landlord in writing — calmly, citing the ordinance or statute — and keep a copy. Many increases are simple errors that get corrected once flagged.
• Pay the lawful amount and document it, so you can’t be accused of nonpayment while the dispute is open.
• File a complaint. City RSO tenants can report violations to LAHD; unincorporated-county tenants can file with DCBA; any tenant can consult the state resources under AB 1482.
• Get help. LA has free tenant-counseling and legal-aid organizations that handle rent-cap and notice disputes at no cost.

Keep in mind that a rent increase can also be a disguised attempt to push you out. If yours arrives alongside pressure to leave, review your protections in our guide to just-cause eviction rules in Los Angeles, and make sure any deposit issues are handled correctly under the California security-deposit rules.

Frequently asked questions

Can my landlord raise the rent twice in one year?

Under the City RSO and the County RSTPO, no — only one increase is permitted per 12-month period. Under AB 1482, up to two increases are allowed in 12 months, but together they still cannot exceed the annual cap (the lower of 5% + regional CPI or 10%).

My mailing address says “Los Angeles” — am I covered by the City RSO?

Not necessarily. Many neighborhoods with an L.A. mailing address are actually in unincorporated LA County, which is governed by the County RSTPO, not the City RSO. Confirm your true jurisdiction with a parcel or district lookup before assuming which rules apply.

Is my single-family house rent-capped?

Usually a single-family home or condo is exempt from AB 1482 — but only if the owner is not a corporation, REIT, or corporate-member LLC, and the landlord served you the specific written exemption notice AB 1482 requires. Without that notice, the cap still applies. Single-family homes are also generally outside the City RSO.

How much notice must I get before the rent goes up?

Under Civil Code § 827, it’s 30 days’ written notice if the increase over the past 12 months is 10% or less, and 90 days if it’s more than 10%. Add 5 days if the notice is mailed. An increase served without proper notice is not yet effective.

What if my rent increase is higher than the legal cap?

The portion above the cap is generally unenforceable. You owe only the legally allowed amount. Tell your landlord in writing citing the ordinance, keep paying the lawful figure, and if it isn’t corrected, file a complaint with LAHD (City), DCBA (unincorporated county), or seek free tenant legal aid.
