California's Hidden Fee Law Triggers Lawsuit and DOJ Enforcement Push
California's SB 478 hidden fee law took effect July 1, 2024, and immediately prompted legal and enforcement action.
Why it matters: California businesses and their legal teams must act swiftly to prevent exposure to consumer lawsuits and state enforcement. The new law applies broadly across industries and heightens transparency and compliance demands.
- SB 478 mandates that nearly all advertised prices include mandatory fees starting July 1, 2024.
- Restaurants and bars are excluded if fees are clearly disclosed everywhere prices are listed, per SB 1524.
- Attorney Mark Chavez filed a consumer class action against a major gym chain over hidden fees two days after implementation.
- California DOJ signaled robust enforcement, warning businesses about both civil and regulatory actions for violations.
California’s SB 478 went into effect on July 1, 2024, banning businesses from advertising prices that do not include all required fees. The law targets hidden service charges and administrative costs, requiring that all advertised or quoted prices reflect what consumers will actually pay.
- SB 478’s reach is wide, covering most sectors except government-imposed fees and shipping costs. The California Department of Justice (DOJ) stresses that honest and transparent pricing is now required statewide.
- An exemption was established by SB 1524. Restaurants and similar food service businesses may add surcharges if these are conspicuously disclosed wherever menu prices are shown.
- Litigation began almost immediately: On July 3, 2024, attorney Mark Chavez brought a consumer class action against a major fitness chain, alleging deceptive advertising of membership rates that failed to include required processing fees.
Regulatory enforcement is underway. The DOJ released compliance guidance emphasizing that noncompliant companies face both investigation and possible civil penalties. Updates from major law firms highlight heightened risk for client-facing industries such as hotels, event venues, gyms, and spas that do not promptly update their pricing practices.
Businesses and legal counsel are now urgently reviewing price disclosures and advertising strategies. The stakes include civil litigation, class actions, and enforcement actions—all based on how mandatory fees are presented to consumers.
By the numbers:
- 1 — consumer class action lawsuit filed within two days of SB 478 taking effect
- July 1, 2024 — date SB 478 became effective, impacting virtually all California businesses
Yes, but: So far, only one lawsuit has been publicly filed, but legal experts expect more claims as enforcement and awareness increase.
What's next: Ongoing monitoring by the California DOJ and further private lawsuits are expected as more businesses adjust compliance practices under the new law.
