Algorithmic Rent-Pricing Litigation Expands Under New State and Local Laws

States and municipalities across the U.S. have enacted laws restricting landlords' use of algorithmic rent-pricing software, spawning a new wave of litigation against multifamily housing companies in cities including San Francisco, San Diego, Seattle, and Philadelphia. These new statutes provide simpler pathways to liability than traditional antitrust claims and authorize substantial penalties—up to $1,000-$7,500 per violation—with each month of use potentially constituting a separate violation. The litigation draws on evidence from earlier RealPage antitrust cases and represents follow-on claims targeting landlords' alleged use of revenue-management products that share competitor pricing information.
