SAN FRANCISCO (KRON) — A California bill that aims to limit the audio levels of commercials on streaming platforms such as Netflix and Hulu was signed into law by Governor Gavin Newsom on Monday. The legislation will require commercials to be no louder than the primary content being streamed.

Senate Bill 576 was introduced by Senator Thomas Umberg (D-Santa Ana), who said it was “inspired by baby Samantha and every exhausted parent who’s finally gotten a baby to sleep, only to have a blaring streaming ad undo all that hard work.”

The new California law follows in the footsteps of the Commercial Advertisement Loudness Mitigation (CALM) Act that was passed in 2010. The CALM Act directs the Federal Communications Commission (FCC) to prohibit broadcast television stations from boosting the volume of commercials beyond the levels at which the programs are playing.

“By signing SB 576, California is dialing down this inconvenience across streaming platforms, which had previously not been subject to commercial volume regulations passed by Congress in 2010,” Newsom said in a statement.

The new law is set to go into effect on July 1, 2026.
