On May 9, 2024, Maryland Governor Wes Moore signed the Maryland Online Data Privacy Act of 2024 (MODPA), making Maryland the 18th state to enact comprehensive privacy legislation. MODPA introduces stricter rules for businesses that collect, process, or disclose personal data.
The Act takes effect on October 1, 2025, but does not apply to activities before April 1, 2026. Although several elements of MODPA align with other comprehensive state privacy laws, other unique elements of MODPA potentially broaden its applicability to more businesses and impose more stringent standards and restrictions on data processing activities.
Consumer Rights and Business Obligations
Similar to other state privacy laws, MODPA grants consumers the right to:
Access, correct, delete, and export their personal data.
Opt out of the sale of personal data, targeted advertising, and profiling.
The Act also requires businesses (controllers) to post privacy policies, conduct data privacy impact assessments, and prohibits discrimination against consumers who exercise the above rights regarding their data.
However, while MODPA shares many common elements with other state laws, it introduces unique provisions that could create new challenges for compliance.
Notable Unique Elements
MODPA applies to businesses operating in Maryland or targeting Maryland residents if they meet either of these criteria:
This threshold of 35,000 individuals is significantly lower than the thresholds for applicability found in similarly populous states, which typically require data collection from 100,000 or more consumers.
MODPA’s definitions of biometric, consumer health, and sensitive personal data differ from other states, broadening what qualifies as “sensitive.”
MODPA imposes more stringent data minimization requirements regarding the collection or processing of both personal data and sensitive personal data than other state privacy laws or, in some cases, the European Union’s GDPR.
MODPA prohibits selling the personal data of any Maryland resident that a business knows or should have known is under 18. Such data is also prohibited from use for targeted advertising purposes. This rule may require businesses to implement age verification mechanisms to ensure compliance.
Businesses must regularly conduct assessments of activities that present a “heightened risk of harm” to consumers. These include:
Importantly, MODPA uniquely requires businesses to conduct data protection assessments for each algorithm they use.
The Maryland Attorney General and the Division of Consumer Protection have exclusive enforcement authority. Regarding alleged violations prior on or prior to April 1, 2027, violators will have 60 days to address such alleged violations, after which penalties of up to $10,000 per violation (a $25,000 for subsequent violations) may be imposed. No private right of action is available under MODPA.
MODPA’s unique provisions will require several businesses to expand their data privacy policies and practices beyond compliance with existing legal regimes. Review of existing policies and preemptive planning with certified information privacy professionals and legal counsel is recommended for businesses processing Maryland consumer data in order to avoid unnecessary business disruption or significant penalties for noncompliance.
