Bill > HB434

This bill prohibits landlords from using certain algorithmic devices, which are tools that use calculations based on data to advise on rent amounts, recommend lease renewal terms, ideal occupancy levels, or other lease conditions, when that data includes "nonpublic competitor data" – information not widely available to the public and obtained from competing entities. This prohibition aims to prevent landlords from using such devices to unfairly set rent, lease renewal terms, occupancy levels, or other lease conditions for residential rental properties. Violating this law will be considered an unfair, abusive, or deceptive trade practice under the Maryland Consumer Protection Act, and the bill applies only to rental agreements executed on or after its effective date of October 1, 2026.
