What it does
This bill makes it illegal for landlords to use pricing software, algorithms, or data-sharing services that coordinate rental prices across multiple properties. It treats rent-fixing coordination as an automatic violation of antitrust law (Sherman Act and FTC Act), giving the FTC and state attorneys general power to sue coordinators and landlords who use them. The bill aims to prevent algorithmic collusion that artificially inflates rents.
Why we flagged it
The bill's core mechanism is to classify rent-coordination software and data-sharing as per se antitrust violations, empowering the FTC and state AGs to prosecute landlords and vendors. It is a straightforward antitrust measure, not a price-control or rent-cap statute.
What the text implies
- The bill's definition of 'coordinating function' is broad enough to potentially capture legitimate property-management tools (e.g., market-rate benchmarking, occupancy optimization) if they use algorithms trained on multi-property data. Vendors may face litigation risk even for non-collusive uses.
- Enforcement relies on FTC and state AG resources; without adequate funding, the bill may remain largely symbolic. Landlords using opaque or decentralized coordination methods may evade detection.
