The California Consumer Privacy Act gives California residents rights over the personal information businesses collect about them, and places duties on the businesses that collect it. It took effect in 2020. The California Privacy Rights Act, approved by voters in November 2020, amended the CCPA from 2023, added rights to correct and to limit the use of sensitive personal information, introduced data minimisation and purpose limits, and created the California Privacy Protection Agency. The CPRA amended the CCPA. It is not a separate law that replaced it.
The Act applies to businesses, not only to consumer-facing ones. A business must give notice at collection, keep a privacy policy updated at least every 12 months, honour requests to know, delete and correct, and let consumers opt out of the sale or sharing of their personal information, including through opt-out preference signals. Collection and use must be reasonably necessary and proportionate to the disclosed purposes, and the business must implement reasonable security procedures and practices.
The regulations that took effect on 1 January 2026 add three significant obligations, each with its own phased dates. Businesses whose processing presents significant risk to consumers’ privacy must carry out and document risk assessments. Businesses whose processing presents significant risk to security must complete an annual independent cybersecurity audit and submit a certification to the Agency. Businesses that use automated decisionmaking technology to make significant decisions about consumers must give pre-use notice, opt-out and access rights from 1 January 2027.
Both the Agency and the Attorney General can enforce the Act, and consumers have a private right of action for certain data breaches caused by a failure to maintain reasonable security. For most organisations the work is operational: knowing what personal information they hold and where, answering requests on time, managing contracts with service providers, and keeping the records that show it.
