The Red Light Abatement Act is a vice law in California that was intended to curtail or eliminate prostitution.

The Act was passed by the California legislature and signed by Governor Hiram Johnson in 1913, and became effective on 3 November 1914.

[2] Under the act owners of the buildings where prostitution takes place are fined by the city.

[citation needed] As a result, prostitution moved to the streets, making the practice more dangerous.

The legislation was still in use in 2018, when it was used to shut down San Jose massage parlors run by Hung Nguyen.
