Attorney General Anthony G. Brown today named four more landlords in Maryland’s suit against RealPage and residential landlords that used its revenue management software to coordinate prices and raise rents on thousands of Marylanders. The four new defendants are Camden Development Inc., Harbor Group Management Company LLC, Equity Residential Management LLC, and Trinity Property Consultants LLC.

These landlords used RealPage’s rent-setting algorithm to drive up housing costs for thousands of Marylanders,” said Attorney General Brown. “Our Office will not stop until we get complete relief or Marylanders, hold these Defendants accountable, and secure guardrails for this technology to protect renters from these costly and unlawful schemes.

The landlords used RealPage software to fix rents at more than 30 apartment buildings in Baltimore City and Anne Arundel, Baltimore, Harford, Howard, Montgomery, and Prince George’s counties, raising rents for thousands of Marylanders by as much as $130 a month.

These four new defendants in the RealPage lawsuit have been added to eight of the largest residential landlords in Maryland that were named in the lawsuit when it was filed on January 15, 2025. The defendant landlords are alleged to have unlawfully colluded to raise rents by agreeing to exchange competitively sensitive information and collectively setting rents based on RealPage’s technology that inflated prices, costing renters millions of dollars.
