California Bans Streaming Ads Louder Than Their Shows Starting July 1

California’s SB 576, signed by Governor Newsom in October 2025, takes effect July 1, 2026, barring any video streaming service from playing ad audio louder than the content it interrupts within the state. The measure extends to streaming the same loudness constraint that broadcast, cable, and satellite providers have operated under since the federal CALM Act, which caps commercials at the average volume of surrounding programming.

How streaming companies will actually comply remains unannounced. They could geofence the adjustment to viewers detected in California, but it’s more likely they apply it nationwide rather than maintain separate audio pipelines per state. That bet looks safer given Illinois has passed a similar requirement landing July 1, 2027, signaling a broader regulatory trend rather than a one-off.

The practical upshot is a consumer-protection rule catching streaming up to legacy TV norms, with the messy compliance details left to platforms to sort out before the deadline.
