An Act relative to preventing algorithmic rent fixing in the rental housing market

This bill creates a new chapter in Massachusetts law to prevent companies from using software to coordinate rental prices among landlords. It defines "service providers" as any entity that collects rental data and recommends prices to landlords, and prohibits landlords from paying these services to set or influence rent amounts. The law also bans agreements among landlords not to compete with each other on pricing and makes it easier for tenants to sue for violations by removing barriers like arbitration clauses and class-action waivers. Landlords who violate the rules could face legal penalties, and successful plaintiffs would be entitled to recover their legal costs and attorney fees.
