Los Angeles Rent Increase Rules 2026
Updated July 2026. Figures and law current as of this date.
For 2026, Los Angeles landlords can raise rent by a flat 3% on RSO properties (July 1, 2026 - June 30, 2027). The old 1% utility add-ons were eliminated on February 2, 2026. AB 1482 properties allow 8.7% (5% + 3.7% CPI) from August 1, 2026 - July 31, 2027. LA County unincorporated (RSTPO) units are capped at 1.919%. Most rent increases require at least 30 days written notice.
If you own a rental property in Los Angeles, understanding how much, and when, you can legally raise rent is essential. The rules differ dramatically depending on whether your property falls under the Rent Stabilization Ordinance (RSO), California's AB 1482, or the Just Cause Ordinance (JCO). Getting it wrong can result in thousands of dollars in penalties and required refunds to tenants.
What Changed in 2026: Los Angeles Rent Increase Rules
The Los Angeles rent increase rules for 2026 look very different from a year ago. On December 12, 2025, the LA City Council approved the first major overhaul of the RSO formula in more than 40 years, and every piece of that reform is now in effect. Here is exactly what changed, what the current limits are, and how 2026 compares to 2025.
LAHD Rent Increase for 2026: The RSO Cap Is a Flat 3%
The Los Angeles Housing Department (LAHD) has published the RSO rent increase for 2026: a flat 3%, effective July 1, 2026 through June 30, 2027, unless the City Council amends it. The bigger story is what disappeared. Effective February 2, 2026, landlords can no longer add 1% for providing gas or 1% for electricity, which kills the old 5% maximum. The 10% increase for an added dependent is also gone (a 10% increase for an additional tenant who is not a dependent still applies). Going forward, LAHD calculates the annual RSO increase at 90% of CPI, with a 1% floor and a 4% ceiling.
LA County Rent Increase Limit for 2026 (Unincorporated Areas)
The LA County rent increase limit for unincorporated areas is far lower than the city's cap. Per the county's Department of Consumer and Business Affairs (DCBA), fully covered RSTPO units are limited to 1.919% from July 1, 2026 through June 30, 2027, down slightly from 1.930% the prior year. Qualifying small property landlords may add 1% (2.919% total) and luxury units may add 2% (3.919% total). The county formula is 60% of the CPI change over the 12-month period ending in September, capped at 3% for general units.
2025 vs 2026 Rent Increase Limits Compared
| Law | 2025 Rule | 2026 Rule (Current) |
|---|---|---|
| LA City RSO | 3% + up to 2% utility add-ons (max 5%) | Flat 3%; add-ons eliminated Feb 2, 2026 |
| AB 1482 (LA region) | 8% (Aug 2025 – Jul 2026) | 8.7% (Aug 2026 – Jul 2027) |
| LA County RSTPO | 1.930% (Jul 2025 – Jun 2026) | 1.919% (Jul 2026 – Jun 2027) |
Step 1: Determine Which Law Applies to Your Property
The first, and most critical, step is identifying which rent control law governs your rental property. Los Angeles landlords must navigate three overlapping regulatory frameworks.
| Law | Applies To | 2026-2027 Limit | Frequency |
|---|---|---|---|
| LA RSO | Built on/before Oct 1, 1978 | 3% | Once per 12 months |
| AB 1482 | 15+ years old (rolling)* | 8.7% | Once per 12 months |
| LA County RSTPO | Unincorporated areas, pre-1995 | 1.919% | Once per 12 months |
| No Cap | Built within last 15 years | Market rate | Per lease terms |
*AB 1482 only applies if not covered by stricter local law (like RSO) and certain exemptions don't apply.

The Rent Stabilization Ordinance applies to approximately 650,000 rental units in the City of Los Angeles: primarily apartments and multi-family buildings constructed on or before October 1, 1978.
Current RSO Rent Increase Limits
- Current increase: 3% flat, effective July 1, 2026 through June 30, 2027 (unless the City Council amends it)
- Utility add-ons: Eliminated. As of February 2, 2026, landlords can no longer add 1% for providing gas or electricity
- New formula: 90% of CPI, with a 1% minimum floor and a 4% maximum cap
- Dependent increase: The old 10% increase for an added dependent is no longer permitted; a 10% increase for an additional tenant (not a dependent) still applies
The RSO overhaul approved by the LA City Council on December 12, 2025 is now live. Annual increases are calculated at 90% of CPI (down from 100%), with a maximum cap of 4% (down from 8%) and a minimum floor of 1% (down from 3%). Under this formula, LAHD has set the increase at a flat 3% for July 1, 2026 through June 30, 2027.
RSO Rent Increase Requirements
- Timing: Only one increase permitted per 12-month period
- Notice: Minimum 30 days written notice required
- No banking: Unused increases cannot be saved for future years
- Registration: Property must be properly registered with LAHD
AB 1482 Rent Increase Rules (August 2026 – July 2027)
California's Tenant Protection Act (AB 1482) provides statewide rent caps for properties not covered by stricter local ordinances. For increases taking effect August 1, 2026 through July 31, 2027, the limit for Los Angeles area properties is 8.7% (5% base + 3.7% CPI, per April 2026 BLS data for the Los Angeles-Long Beach-Anaheim region). Increases that took effect between August 1, 2025 and July 31, 2026 were capped at 8%.
AB 1482 Applies When:
- Property was built more than 15 years ago (a rolling window; as of 2026, roughly pre-2011 construction)
- Not covered by a stricter local rent control ordinance
- Not a single-family home with proper exemption notice provided
- Not owner-occupied duplex
AB 1482 Exemptions
Your property may be exempt from AB 1482 rent caps if:
- New construction: Built within the last 15 years (rolling basis)
- Single-family homes: Not owned by corporation, REIT, or LLC with corporate member, and proper written notice provided to tenant
- Owner-occupied duplexes: Owner lives in one unit
- Affordable housing: Deed-restricted units
Warning: Even if exempt from AB 1482 rent caps, your property may still be subject to Just Cause Eviction requirements. Single-family homes require written exemption notice to tenants using specific statutory language.
Notice Requirements for All Rent Increases
California law establishes strict notice requirements that apply to all rental properties, regardless of rent control status.
| Increase Amount | Required Notice | Delivery Method |
|---|---|---|
| 10% or less (in 12 months) | 30 days minimum | Personal delivery, mail, or post + mail |
| More than 10% (in 12 months) | 90 days minimum | Personal delivery, mail, or post + mail |
Proper Notice Must Include:
- Current rent amount
- New rent amount
- Effective date of increase
- Landlord signature and date
- Proper statutory language (for AB 1482 properties)

Misclassifying Your Property
Applying AB 1482 limits to an RSO unit (or vice versa) can result in overcharging and tenant claims. Always verify which law applies before calculating increases.
Raising Rent Too Soon
Both RSO and AB 1482 limit increases to once per 12 months. Multiple increases within a year, even if they total less than the cap, may violate timing rules.
Insufficient Notice Period
Rent increases without the correct notice period are invalid. A 30-day notice mailed on January 1st means the increase cannot take effect until February 1st at earliest.
Adding Unapproved Fees
Many "extra" charges, like new pet rent, parking fees, or utility charges, are considered part of rent and must comply with the same caps. Adding $50/month pet rent counts toward your annual increase limit.
Attempting to Bank Increases
LA RSO does not allow banking unused rent increases. If you skip this year's 3% increase, you cannot apply 6% next year. Each year's allowable increase must be used or forfeited.
Penalties for Illegal Rent Increases
Los Angeles enforces rent control violations aggressively. Landlords who exceed legal limits face serious consequences:
- Rent rollbacks: Requirement to reduce rent to the legal amount
- Refunds: Mandatory repayment of all excess rent collected
- Treble damages: Up to three times the overcharge in some cases
- Attorney fees: Payment of tenant's legal costs
- Civil penalties: Additional fines imposed by the city
- Criminal prosecution: In egregious cases
Step-by-Step: How to Legally Raise Rent
Verify Property Classification
Use ZIMAS or contact LAHD to confirm whether your property is RSO-covered, AB 1482-covered, or exempt. This determines your maximum allowable increase.
Calculate Your Allowable Increase
RSO: flat 3% (utility add-ons eliminated February 2026). AB 1482: 5% + CPI, which equals 8.7% for increases effective August 1, 2026 through July 31, 2027. Never exceed the applicable cap for your property type.
Check Timing Requirements
Confirm at least 12 months have passed since the tenant's last rent increase. Review lease renewal dates and market conditions.
Prepare Written Notice
Draft a compliant rent increase notice with all required information: current rent, new rent, effective date, and proper statutory language.
Serve Notice Properly
Deliver notice at least 30 days before the effective date (90 days if increase exceeds 10%). Keep proof of delivery for your records.
Frequently Asked Questions
For RSO properties, a flat 3% from July 1, 2026 through June 30, 2027; the old utility add-ons were eliminated in February 2026. For AB 1482 properties, 8.7% (5% + 3.7% CPI) from August 1, 2026 through July 31, 2027. Properties exempt from both may raise rent to market rate with proper notice.
At least 30 days written notice for increases of 10% or less within a 12-month period. For increases exceeding 10%, landlords must provide 90 days notice. This applies statewide to all rental properties.
RSO is a Los Angeles city law for properties built on or before October 1, 1978, with a stricter 3% rent cap. AB 1482 is California state law for most properties at least 15 years old not covered by stricter local laws, allowing 5% + CPI (max 10%). RSO supersedes AB 1482 for covered properties.
No. Los Angeles RSO does not allow banking of unused rent increases. If you skip an annual increase, you cannot apply it retroactively. Each year's allowable increase must be used during that period or forfeited permanently.
Illegal rent increases can result in rent rollbacks, mandatory refunds to tenants, monetary damages up to three times the overcharge, payment of tenant's attorney fees, civil penalties from the city, and potential criminal prosecution in severe cases.
Vacancy decontrol remains in effect: landlords can set rent at market rate when all original tenants vacate. However, once a new tenant moves in, rent increase caps apply to that tenancy going forward.
