New Jersey Bans Algorithmic Rent-Setting Software, Calling It 'Collusion by Algorithm'

For years, renters across the United States have faced inexplicable, synchronized rent hikes, often feeling as though they were bidding against an invisible machine. In many cases, they were. On Monday, New Jersey took decisive action against this practice, officially banning landlords from using algorithmic software to set or recommend rental prices.[1]

Governor Mikie Sherrill signed the Forbidding the Algorithmic Inflation of Rent (FAIR) Act into law, marking one of the most aggressive state-level crackdowns on property technology platforms. The legislation targets a specific, controversial mechanism: software that ingests private, non-public data from competing landlords to generate automated pricing recommendations.[1][2]

State officials and housing advocates have characterized the practice as "collusion by algorithm." By relying on third-party platforms to dictate pricing, landlords can effectively move in lockstep, artificially inflating the housing market without ever holding a backroom meeting.[1][2]

The mechanics of these platforms rely on a massive pooling of proprietary information. Landlords feed sensitive data—including actual rents paid, occupancy rates, and lease expiration dates—into a centralized algorithmic engine. The software then processes this aggregated competitor data to advise each property manager on exactly how much to charge for an available unit.[4]

This "hub-and-spoke" model allows property owners to bypass traditional price-fixing laws, achieving the same financial outcome as a cartel while maintaining a veneer of independent decision-making. The FAIR Act explicitly brings this high-tech coordination under the umbrella of the New Jersey Antitrust Act.[4][6]

The scale of algorithmic pricing in the residential market is staggering. According to a recent analysis, a single dominant software provider, RealPage, had at least 600 corporate customers using its systems to price over 4.5 million residential units nationwide. That figure represents approximately eight percent of all rental units in the United States.[3]

The financial toll on tenants has been heavily documented. A 2024 report by the White House Council of Economic Advisers found that rent-pricing algorithms added an average of $70 per month to rents in buildings that utilized the software. Across the country, this artificial markup cost renters an estimated $3.8 billion in a single year.[3]

Under the new New Jersey law, it is now illegal to sell, license, or use these algorithmic devices within the state. The legislation empowers the Attorney General to file civil actions against violators, seeking damages, restitution of illegal profits, and civil penalties of up to $1,000 per violation.[4]

Crucially, the FAIR Act is not a blanket ban on all property management technology. The law specifically exempts ordinary spreadsheets, publicly available rent estimates, property-listing databases, and software used to comply with government affordability programs. The defining trigger for a violation is the exchange and algorithmic processing of private, competitive information.[1][4]

The property technology industry has fiercely pushed back against the narrative of digital collusion. Companies like RealPage and Yardi Systems maintain that their software does not force landlords to accept price recommendations and that the algorithms are designed to maximize overall revenue by keeping units occupied, which they argue ultimately benefits the housing ecosystem.[7]

As municipalities and states have begun outlawing the software, the industry has launched a novel legal defense. In lawsuits challenging similar bans in New York and Berkeley, California, RealPage has argued that its algorithmic recommendations constitute "rental advice" and are therefore protected speech under the First Amendment.[5][6]

This legal strategy relies heavily on the precedent set by Citizens United, asserting that a ban on algorithmic pricing is an unconstitutional, content-based restriction on corporate speech. If federal courts accept this premise, it could severely undermine the ability of states to regulate AI-driven commerce and price-setting.[5][6]

The aggressive litigation has already produced a chilling effect in some jurisdictions. Earlier this year, the city council in Portland, Oregon, shelved a proposed ban on rent-setting algorithms after industry lobbyists threatened expensive First Amendment lawsuits.[6]

Despite these legal threats, the regulatory momentum against algorithmic pricing continues to accelerate. New Jersey joins a growing coalition of jurisdictions—including New York State, San Francisco, and Philadelphia—that have enacted strict prohibitions.[5][6]

These legislative efforts are running parallel to massive federal enforcement actions. The United States Department of Justice, alongside multiple state attorneys general, is actively pursuing antitrust litigation against RealPage and several major corporate landlords, seeking to dismantle the data-sharing networks entirely.[6][7]

For New Jersey renters, the FAIR Act represents a tangible victory in an increasingly unaffordable housing landscape. By severing the digital ties that allow corporate landlords to coordinate pricing, the state is attempting to force property owners back into genuine competition, ensuring that the invisible hand of the market is no longer guided by a centralized algorithm.[1][2]
