Pasadena Rent Increase Limit 2026–2027: The 2.5% AGA Explained
Pasadena's 2.5% Annual General Adjustment starts October 1, 2026. See the October 31 Rental Registry deadline, current fee, late-fee schedule and compliance checks.
Quick answer: Pasadena's next AGA is 2.5%
The City of Pasadena Rent Stabilization Department says the Annual General Adjustment for covered rent-stabilized units is 2.5% for the period October 1, 2026 through September 30, 2027. The Pasadena Rental Housing Board adopted the figure on June 18, 2026.
The 2.5% figure is not a blanket permission to raise every Pasadena rent by 2.5%. It applies to existing tenancies in covered rental units under Pasadena Charter Article XVIII, and the landlord must still satisfy the applicable coverage, timing, registration and notice requirements before an increase takes effect.
Why the percentage changed
Pasadena calculates the AGA under Charter section 1808 using 75% of the annual change in the applicable Los Angeles-area Consumer Price Index for the 12-month period ending in March, then rounds to the nearest one-quarter of a percent. The City reports a 3.4% CPI change for the 2026–2027 calculation; 75% of that is 2.55%, which rounds to 2.5% under the Charter formula.
That formula matters because the annual Pasadena figure should be rechecked each cycle instead of copied forward from an older notice or spreadsheet. The prior 2025–2026 AGA was 2.25%; the new 2.5% period begins October 1, 2026.
Coverage comes before the calculation
Pasadena's local rules distinguish covered rent-stabilized units from properties or tenancies that may fall outside the AGA provisions. Do not decide coverage from the mailing address, building appearance or age estimate alone. Use the City's current Rent Stabilization Department resources and property records to verify the actual unit.
The City also explains that Charter Article XVIII includes broader registration and just-cause requirements that can reach properties differently from the rent-increase provisions. A property being registered does not by itself prove that a particular tenancy is subject to the AGA cap.
One increase per 12 months still matters
The City's August 31 announcement states that landlords may apply the AGA increase only once per 12-month period. A new annual AGA period therefore does not automatically reset the clock for a tenancy that received an increase more recently.
Before preparing a notice, check the tenant ledger and the effective date of the last rent increase. The proposed effective date, not simply the date the notice is drafted, should be tested against the applicable 12-month rule and all other current requirements.
Registration and compliance can affect the workflow
Pasadena's 2026 Rental Registration cycle runs from September 1 through October 31, 2026. The City says covered residential rental properties must be registered annually and that specified changes, including a rent increase, tenancy end, new tenancy or ownership change, must be updated in the Rental Registry within 30 days.
Treat registration, rent calculation and notice preparation as separate checkpoints. A mathematically correct 2.5% calculation does not cure a separate compliance problem, and a completed registry entry does not replace a legally sufficient rent-increase notice.
October 31 registration deadline, current fee and late-fee schedule
The City's current Rental Registry page lists the 2026–2027 Rental Housing Fee at $236.54 per unit for units that owe the fee, due October 31, 2026. Pasadena says the fee cannot be passed on to tenants and cannot be prorated. Some units can be exempt from the fee or registration requirements, but owners should use the City's exemption process rather than assuming an exemption from property type alone.
Pasadena provides a seven-day grace period through November 7, 2026 with no late fee. The City's current schedule then lists a 15% late fee ($35.48 per unit) for November 8–December 15, 2026, 30% ($70.96) for December 16, 2026–January 29, 2027, and 50% ($118.27) beginning January 30, 2027. The City also warns that noncompliance can affect rent increases and other landlord remedies, so verify registry status before acting.
Use the official Pasadena source before serving a notice
A useful internal workflow is: verify the exact unit and tenancy, confirm current registration status, identify the lawful base rent, review the date of the last increase, calculate the proposed amount, and then prepare the written notice using the rules in effect for the intended effective date.
