Do you support the rent increase caps currently in place for your community's rental units?

Pasadena will transition to a 2.5% rent increase cap for rent-stabilized housing units effective October 1, 2026. This adjustment replaces the previous 2.25% limit that is set to expire on September 30.

Why it matters

The Pasadena Rental Housing Board establishes these annual adjustments based on 75% of the Consumer Price Index increase for the Los Angeles area. This mechanism seeks to balance rising operational costs for property owners with tenant protections against steep rent surges.

The new 2.5% cap is calculated using 75% of the annual 3.4% increase in the Los Angeles area Consumer Price Index. Eligible landlords may only apply this increase once in a 12-month period after paying a $236.54 annual fee per unit.

The players

Pasadena Rental Housing Board

This local government body is responsible for managing the city's rent stabilization program and determining annual adjustment rates.

The details

Landlords are required to register their units with the city and pay the housing fee to be eligible for the annual increase. Property owners must also provide tenants with written notice at least 30 days before any rent adjustment takes effect; however, multifamily units built after 1995 and single-family homes remain exempt from the cap.

June 18, 2026: The Pasadena Rental Housing Board adopted the new adjustment.
Sept. 30, 2026: The previous 2.25% rent cap expires.
Oct. 1, 2026: The new 2.5% rent cap takes effect.
Oct. 31, 2026: The registration period for units ends.
Nov. 8, 2026: Late fees for the Rental Housing Fee begin.

Culture Shift

This policy change reflects the growing trend of municipal rent stabilization programs designed to combat urban housing affordability crises. By anchoring rent hikes to the Consumer Price Index, Pasadena is following a broader national model of creating predictable, data-driven cost controls for the rental market.

Tenants in rent-stabilized units should check their lease agreements and upcoming notices to verify if a rent hike is compliant with the new 2.5% limit. Landlords must ensure their units are fully registered with the city to legally implement these adjustments.

The takeaway

Property owners should ensure all required filings are completed before the late fee deadline to avoid penalties. Residents in covered units are encouraged to monitor their mailbox for mandatory 30-day written notifications regarding potential rent increases.

What happens next

The city’s registration period for rental units concludes on October 31, 2026, with late fees for the $236.54 annual fee scheduled to begin on November 8, 2026.
