RealPage, Inc. is at the center of one of the most significant antitrust enforcement actions in U.S. housing history. The company’s rent-pricing algorithm — accused of enabling coordinated rent inflation across hundreds of apartment markets — has generated a Department of Justice settlement in November 2025, an active California Attorney General lawsuit, and more than 100 private class action lawsuits filed across the country. If you are litigating one of these cases, or if your client has a claim arising from RealPage’s software and its users, serving RealPage properly in California requires attention to entity and agent details.
The Correct Legal Entity
RealPage, Inc. is the correct entity. It is a Texas corporation qualified to do business in California as a foreign corporation. RealPage was acquired by private equity firm Thoma Bravo in 2021 in a take-private transaction worth approximately \$10.2 billion. It is no longer publicly traded, but its legal entity — RealPage, Inc. — remains intact and is the correct defendant for California litigation.
Do not confuse RealPage with individual property management companies that used its software. If your client’s claim is specifically about the algorithm and its anticompetitive effects, RealPage Inc. is the defendant. If the claim is about a specific landlord’s use of RealPage pricing at a particular property, you may also need to name that landlord entity separately.

Context: The Rent-Fixing Litigation
The RealPage litigation centers on the company’s YieldStar algorithmic pricing software, which aggregated non-public rent data from competing landlords to generate pricing recommendations. The DOJ, private plaintiffs, and multiple state attorneys general allege that this constitutes horizontal price-fixing — coordination among competitors — in violation of federal antitrust law.
Key developments:
• November 2025: DOJ consent decree — RealPage agreed to a settlement with the Department of Justice requiring it to stop sharing non-public competitor data for pricing purposes and to implement a compliance program
• California AG lawsuit — active as of 2026 — the California Attorney General filed a separate state antitrust action against RealPage that is proceeding independently of the DOJ settlement
• 100+ class actions — private plaintiffs across multiple jurisdictions have filed class actions alleging that RealPage’s software caused them to overpay rent. Several of these cases involve California renters and California properties
This litigation is extraordinarily timely. If you represent renters who overpaid at properties using RealPage’s software, or if you are litigating against a landlord whose pricing was set by RealPage, the window for filing claims and serving defendants is actively open.
What Documents Are Commonly Served
• Class action complaints — the primary document type in this litigation wave
• Subpoenas duces tecum seeking algorithm documentation, pricing data, client lists, and software contracts
• Complaints in intervention in the California AG action
• Cross-claims and third-party complaints in landlord-tenant cases where a landlord seeks to involve RealPage as a contributing party
