S 451 New Jersey Senate · 2026-2027 Regular Session

Establishes "Forbidding the Algorithmic Inflation of Rent (FAIR) Act." *

This bill (S 451) prohibits landlords and property management software from using algorithmic systems to coordinate rental pricing and supply, which the legislature states has contributed to New Jersey's housing affordability crisis. It defines a "coordinator" as any service (including software) that collects pricing data from multiple landlords, analyzes it with algorithms, and recommends rental prices or lease terms - effectively enabling price-fixing. Landlords are banned from subscribing to such services, and coordinators are prohibited from facilitating agreements that restrict competition among rental property owners. The law directly affects landlords, property management companies, and software providers operating in New Jersey's rental market, aiming to increase price competition and reduce rent burdens for renters.

MODERATE
S 451 moved from its introduced version to a first reprint as reported by the Senate Community and Urban Affairs Committee on March 5, 2026, with amendments. The key substantive changes include adding an explicit 'restrain trade' framing, broadening the definition of coordinating function to cover algorithms and other automated processes, creating a new 'affordability controls' definition, and carving out government entities that set rent limits from the definition of 'coordinator.' Two additional co-sponsors were added.
SCOPE

The preamble now explicitly frames the problem as one of restraining trade, not just colluding to raise prices, strengthening the antitrust justification for the bill.

The definition of 'coordinator' now explicitly excludes government entities that set or limit rents or sale prices through affordability controls in accordance with law, preventing the bill from being read to restrict legitimate government rent-setting authority.

New preamble findings were added noting that property management software companies and landlords using algorithmic systems have been subject to public and private litigation for alleged antitrust violations, and that the role of antitrust law in maintaining competitive markets remains vital despite evolving forms of restraint of trade.

DEFINITION

The definition of 'coordinating function' was broadened from 'system, software, or process that uses computation' to 'system, software, algorithm, or other automated process that uses computation,' making it harder for companies to argue their tools fall outside the bill's reach.

A new definition of 'affordability controls' was added, covering rent restrictions established under government programs including Section 8, the Fair Housing Act, NJ Housing and Mortgage Finance Agency programs, and local rent control ordinances.

TECHNICAL

The introductory language of the definitions section was changed from 'As used in this act' to reference a specific pending companion bill by public law number and title citation, suggesting coordination with related legislation.

The claimed rent increase figure from a leading property management software company was changed from 'two to five percent' to 'up to seven percent.'

The bill's summary statement section at the end was removed, which is standard when a bill advances from introduction to committee report.
