California Retaliation Law: What Counts & the Presumption Window (2026)

What counts as retaliation, and the window where the law presumes it

At a glance

• Protection window: 180 days
• Governing authority: Cal. Civ. Code § 1942.5(a)

Who this covers — and who it does not

This page covers landlord retaliation in California — what a landlord may not do after you exercise a protected right.

It does not cover commercial leases, or conduct outside the protected window described below.

What the law prohibits

Cal. Civ. Code § 1942.5：房东不得因租客行使权利或向主管机关投诉可居住性而报复，保护期为 180 天。

⚠️ 条号纠正：加州报复法在 §1942.5，不在 §1942.7（后者是禁止要求租客为动物去爪/去声带的条款）。保护期是 180 天，不是 12 个月 —— 12 个月在 §1942.5 中仅出现于「同一租客 12 个月内只能援引一次」的次数限制。

The protection window

For 180 days after a protected act, certain landlord actions are presumed retaliatory.

加州不采用「推定 + 举证责任转移」结构。房东须在终止通知、涨租通知或其他行为中（及仲裁诉状中）载明其据以善意行事的理由；若该陈述被争议，房东须在审判中证明其真实性。

What a landlord may not do

Burden of proof

房东须在通知或诉状中先行载明善意理由；被争议时，房东在审判中证明该理由的真实性。

但§1942.5(d)（tenants' association / 依法行权）项下的诉讼中，租客承担「产生证据」（producing evidence）的举证责任。这两层结构并存，不是简单的房东担责。

Remedies

Exemptions and limits

同一租客 12 个月内只能援引 §1942.5(a) 一次。房东遵守联邦政府提供租金限制或租金援助的法定义务的，不违反 (c)/(e) 款。

Where the official text and a secondary summary disagree, this page follows the official text and says so. Where a provision admits of more than one reading, that is flagged rather than smoothed over.

When you need a lawyer instead of a tool

A self-help guide is the right starting point for understanding your position. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• Your landlord has filed anything in court already
• You are unsure whether a local ordinance changes the state rule

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
