Proposed legislation would make it illegal for landlords to use software that analyzes market data to set rental prices.
Trenton, NJ – A new bill introduced in the New Jersey Senate aims to crack down on the growing use of algorithm-driven pricing software by landlords, a practice lawmakers say may be driving rent increases across the state during an ongoing housing affordability crisis.
Senate Bill S3657, sponsored by State Sen. Brian P. Stack of Hudson County and Sen. M. Teresa Ruiz of Essex and Hudson counties, would make it unlawful for rental property owners to use algorithmic systems that collect market data and recommend rent prices or occupancy levels. The measure frames the practice as a potential antitrust violation under New Jersey law.
Key Points
• New Jersey lawmakers introduced a bill to ban algorithmic systems used to set rental housing prices
• Landlords using third-party pricing software could face violations under the state’s Antitrust Act
• Supporters argue the technology allows landlords to coordinate pricing and drive rents higher
The legislation comes amid rising concern over software platforms that aggregate rental market data from multiple landlords and use algorithms to recommend optimal pricing strategies. Critics argue these tools allow property owners to move rents in lockstep, reducing competition in the housing market.
According to findings cited in the bill, median rent for a three-bedroom apartment in New Jersey increased roughly 35 percent between 2021 and 2024. In highly competitive markets such as Hoboken, the price of a studio apartment reportedly surged by as much as 61 percent during the same period.
Lawmakers say more than half of renters in the state are now considered “rent burdened,” meaning they spend over 30 percent of their income on housing costs.
Bill targets data-sharing and pricing algorithms
Under the proposal, rental property owners would be prohibited from subscribing to or paying for services that collect rental data from multiple landlords and use computational systems to generate pricing recommendations.
The bill defines these platforms as “coordinators” — companies or services that gather information such as rent levels, supply availability, lease expiration dates, and renewal terms from two or more landlords and then analyze the information using algorithms.
Those systems often produce suggested rent levels or occupancy strategies intended to maximize revenue.
Supporters of the legislation argue the technology effectively allows landlords to coordinate pricing strategies without directly communicating with each other, which could undermine fair market competition.
Antitrust penalties could apply
If enacted, the legislation would classify the use of such systems as a violation of the New Jersey Antitrust Act, exposing landlords and software providers to potential legal penalties.
The bill would also make it unlawful for companies operating these platforms to facilitate agreements that restrict competition in the residential rental market.
Lawmakers cited public statements from a major property management software provider claiming its algorithmic tools allow landlords to “outperform the market” by two to five percent. A company executive has previously suggested the software could contribute to rent increases of up to 14.5 percent.
Housing affordability driving legislative push
The proposal reflects mounting pressure on state officials to address rising housing costs and expand access to affordable housing in New Jersey.
In its findings, the Legislature declared that housing is a “basic human need” and said preventing coordinated pricing practices is one way to protect renters from rapidly escalating costs.
If approved by the Legislature and signed into law, the measure would take effect on the first day of the fourth month following enactment.
The proposal is currently under consideration during the 221st New Jersey Legislature.
