Bill > HB4538

This bill amends Michigan's existing landlord-tenant law to prohibit landlords from using certain algorithmic pricing devices that incorporate nonpublic competitor data to coordinate rental pricing or rental housing market conditions. Specifically, the bill defines an "algorithmic pricing device" as a software or tool that calculates rent amounts using data about local or statewide rent prices, with some exceptions for periodic trade association reports and affordable housing program guidelines. The bill makes it illegal for landlords to use such devices to coordinate pricing or enter into agreements that restrain the rental housing market. Any violation of this prohibition would be considered a violation of Michigan's antitrust reform act. The bill also updates and adds several definitions to the existing law, including new terms like "nonpublic competitor data" and "prospective tenant," and modifies existing definitions related to landlords, rental agreements, and sources of income. The goal appears to be preventing collusion and unfair pricing practices in the rental housing market by restricting the use of sophisticated pricing algorithms that could potentially allow landlords to inappropriately share or coordinate rental pricing information.
