AB 2609 California Assembly · 2025-2026 Regular Session

Tenancy: additional rents and securities: common household pets.

Summary
Existing law, the Costa-Hawkins Rental Housing Act, among other things, authorizes an owner of residential real property to establish initial and subsequent rental rates for a dwelling or unit that meets specified conditions, subject to certain exceptions. Existing law, until January 1, 2030, prohibits an owner of residential real property from, over the course of any 12-month period, increasing the gross rental rate, as specified, for a dwelling or a unit more than 5% plus the percentage change in the cost of living, or 10%, whichever is lower, of the lowest gross rental rate charged for that dwelling or unit at any time during the 12 months before the effective date of the increase, subject to specified conditions. This bill would prohibit an owner of residential real property from charging a tenant additional rent in an amount in excess of 1% of the monthly rental amount due to the residence of a common household pet, as defined, in the dwelling unit. Existing law imposes specified requirements on a security for a rental agreement for residential property. Existing law defines security as any payment, fee, deposit, or charge that is imposed, as specified, to reimburse the landlord for costs associated with processing a new tenant or that is imposed as an advance payment of rent, used for any purpose. Existing law prohibits a landlord from demanding or receive security in an amount or value in excess of an amount equal to one month's rent, in addition to any rent for the first month paid on or before initial occupancy, except as provided. This bill would prohibit a landlord charging a tenant an additional amount of security in excess of the amount equal to 15% of one month's rent due the residence of a common household pet in the premises. This bill would apply these provisions only to a rental agreement entered into or extended on or after January 1, 2027.

MODERATE
AB 2609 was dramatically expanded from a minor technical fix to the Mobilehome Residency Law title into a substantial tenant protection bill that caps pet-related rent and security deposit charges. The amended version adds a new Civil Code section limiting additional rent for common household pets to 1% of monthly rent, and amends the security deposit statute to cap additional pet-related security at 15% of one month's rent. Both provisions apply only to rental agreements entered into or renewed on or after January 1, 2027.
Scope change
Expanded from a narrow technical amendment to one section of the Mobilehome Residency Law to a broad tenant protection bill applying to all residential real property in California, adding new rent and security deposit limitations specifically for common household pets.
REQUIREMENT

New Section 1947.16 prohibits landlords from charging additional rent exceeding 1% of the monthly rental amount due to a common household pet in the dwelling unit.

Amends Section 1950.5 to prohibit landlords from charging additional security exceeding 15% of one month's rent due to a common household pet in the premises.

DEFINITION

Defines 'common household pet' as domestic dogs (excluding hybrids with wolves, coyotes, or jackals) and domestic cats (excluding hybrids with ocelots or margays).

TIMELINE

Both the pet rent cap and pet security deposit cap apply only to rental agreements entered into or renewed on or after January 1, 2027.

SCOPE

The bill's scope expanded from a single nonsubstantive title change to the Mobilehome Residency Law to a comprehensive tenant protection measure covering pet-related rent and security deposit limits across all residential real property, while retaining the original mobilehome title fix as a separate section.
