AB 1157California Assembly·2025-2026 Regular Session
Tenancy: just cause termination: rent increases.
Summary
(1) Existing law prohibits the owner of a residential real property from terminating a tenancy without just cause, as defined, after a tenant has continuously and lawfully occupied a residential real property for 12 months. Among other residential real properties or residential circumstances, existing law exempts from these provisions a residential real property, including a mobilehome, that is alienable separate from the title to any other dwelling unit if the owner meets specified criteria and the tenants have been provided a specified written notice of the exemption. Existing law repeals these provisions on January 1, 2030. This bill would revise these provisions by removing the exemption for separately alienable residential real property and, instead, only exempting a mobilehome if the above-described criteria are met. The bill would delete the January 1, 2030, repeal date, thereby extending these provisions indefinitely. (2) Existing law prohibits an owner of residential real property, except as specified, from increasing over the course of any 12-month period the gross rental rate 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 prior to the effective date of the increase, as specified. This bill would reduce the permissible gross rental rate increase under these provisions to the lesser of 2% plus the percentage change in the cost of living, or 5%. Among other residential real properties, existing law exempts from these provisions a residential real property that is alienable separate from the title to any other dwelling unit, including a mobilehome, if the owner meets specified criteria and the tenants have been provided a specified written notice of the exemption. This bill would revise these provisions by removing the exemption for separately alienable residential real property and, instead, only exempting a mobilehome if the above-described criteria are met. Existing law repeals these provisions on January 1, 2030. This bill would delete the January 1, 2030, repeal date, thereby extending these provisions indefinitely. (3) Notwithstanding the above-described gross rental rate increase prohibition, existing law, upon the expiration of rental restrictions, as defined, authorizes the owner of affordable housing units that meet certain requirements to establish the initial rental rate for the unit, and also authorizes the owner of an assisted housing development who demonstrates compliance with certain requirements under penalty of perjury to establish the initial unassisted rental rate for units in the assisted housing development. Existing law repeals these provisions on January 1, 2030. This bill would remove the January 1, 2030, repeal date, thereby extending the initial rental rate authorizations indefinitely. By extending provisions that require the owner of an assisted housing development to demonstrate compliance with specified requirements under penalty of perjury, the bill would impose a state-mandated program. (4) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
AB 1157 makes three major substantive changes to California tenant protection law: it tightens the rent increase cap from the lesser of 5% plus CPI or 10% down to the lesser of 2% plus CPI or 5%; it narrows the exemption for separately alienable residential real property so that only mobilehomes remain exempt (rather than all such properties); and it removes the January 1, 2030 sunset date, making the just-cause eviction and rent cap provisions permanent. The bill also adds county counsel as an authorized enforcer of nuisance provisions related to motion pictures.
Scope change
The bill expands tenant protections by removing the 2030 sunset date (making them permanent), tightening the rent cap, and narrowing the exemption for separately alienable properties so that only mobilehomes remain exempt rather than all such properties. This means more rental units will be subject to just-cause eviction requirements and lower rent increase limits going forward.
REQUIREMENT
The maximum allowable rent increase over any 12-month period is reduced from the lesser of 5% plus the percentage change in cost of living or 10%, to the lesser of 2% plus the percentage change in cost of living or 5%. This significantly limits how much landlords can raise rents annually.
SCOPE
The exemption from just-cause eviction and rent cap rules for residential real property that is alienable separate from the title to any other dwelling unit is narrowed. Previously, all such properties (including mobilehomes) could be exempt if the owner met certain criteria and provided written notice. Now only mobilehomes qualify for this exemption.
TIMELINE
The January 1, 2030 repeal date for the just-cause eviction provisions (Section 1946.2), rent cap provisions (Section 1947.12), and initial rental rate authorizations (Section 1947.13) is deleted, making these tenant protections permanent rather than temporary.
ENFORCEMENT
County counsel is added as an authorized official (alongside the district attorney and Attorney General) who can commence an action in equity to abate and prevent nuisance related to the exhibition of motion pictures showing intentional killing or cruelty that actually occurred during production.
FISCAL
The fiscal committee determination changes from no to yes, and the state-mandated local program determination changes from no to yes, reflecting that extending the assisted housing compliance provisions (which require owners to demonstrate compliance under penalty of perjury) imposes a state-mandated program on local agencies.
AB 1157 was dramatically expanded from a narrow nuisance enforcement bill into a major tenant protection package. The amendment adds just cause eviction protections, reduces the statewide rent increase cap from 5%+CPI (capped at 10%) to 2%+CPI (capped at 5%), removes the January 1, 2030 sunset date making these provisions permanent, and narrows an exemption that previously covered all separately alienable residential property down to mobilehomes only. The original nuisance provision (adding county counsel as an authorized enforcer for motion picture-related nuisances) is retained but is now a minor part of the bill.
SCOPE
Entirely new tenancy provisions added, amending Civil Code Sections 1946.2 (just cause eviction), 1947.12 (rent increase limits), and 1947.13 (initial rental rates for affordable housing). The bill went from a single-section nuisance amendment to a multi-section tenant protection act.
REQUIREMENT
The maximum allowable rent increase over any 12-month period is reduced from the lesser of 5% plus cost of living or 10%, to the lesser of 2% plus cost of living or 5%. This roughly halves the permissible annual rent increase for covered tenants statewide.
TIMELINE
The January 1, 2030 repeal date is deleted from Sections 1946.2, 1947.12, and 1947.13, making the just cause eviction protections, rent increase cap, and initial rental rate authorizations for affordable housing permanent rather than temporary.
ELIGIBILITY
The exemption for residential real property that is alienable separate from the title to any other dwelling unit (which covered single-family homes and similar properties) is removed. Only mobilehomes retain this exemption, and only if the owner is not a REIT, corporation, or LLC with a corporate member, and tenants have received written notice of the exemption.
FISCAL
Fiscal committee review changed from 'no' to 'yes' and state-mandated local program changed from 'no' to 'yes', reflecting that extending Section 1947.13 (which requires owners of assisted housing developments to demonstrate compliance under penalty of perjury) indefinitely imposes a state-mandated program on local agencies.
ENFORCEMENT
New enforcement provisions added including: tenant civil actions for actual damages, attorney's fees, and up to three times damages for willful violations; Attorney General and city/county authority to seek injunctive relief; presumption of irreparable harm in injunctive actions; and a three-year statute of limitations for rent overcharge claims.
TECHNICAL
Minor corrections in the retained Section 3506 nuisance provision, including fixing duplicated words ('maintained maintained' to 'maintained', 'lessee lessee' to 'lessee') and clarifying language about the purpose of production.
