SYNOPSIS
Establishes "Forbidding the Algorithmic Inflation of Rent (FAIR) Act."
CURRENT VERSION OF TEXT
As amended by the Senate on June 18, 2026.
An Act concerning 2[pricing of] residential2 rental 2[properties] property pricing2 and supplementing P.L.1970, c.73 (C.56:9-1 et seq.).
Be It Enacted by the Senate and General Assembly of the State of New Jersey:
21. This act shall be known and may be cited as the "Forbidding the Algorithmic Inflation of Rent (FAIR) Act."2
2[1.] 2.2 The Legislature finds and declares that:
a. New Jersey is in the midst of an affordable housing crisis, as demonstrated by rental housing industry data showing median rent for a three-bedroom apartment increasing by 35 percent in the State from 2021 through 2024 and a studio in a more urban environment such as Hoboken increasing by 61 percent in the same timeframe.
b. Data from the United States Census Bureau indicates that over 50 percent of renters in New Jersey are deemed "rent burdened," which means an individual spends more than 30 percent of income on rent.
c. Recent national data indicates that landlords of residential rental housing use property management software to collude 1to restrain trade1 and raise residential rental housing prices, which 2[may have] has2 contributed to recent increases in the State.
d. Landlords engaging with the software supply real-time prices and additional lease information to companies managing the software, who proceed to use algorithms to fix rental prices. As a result, competition decreases and 2[typically]2 rental prices increase.
e. A leading property management software company in the United States hinted at the outcome of using its software by stating on its website that it enables landlords to "outperform the market" by 1[two to five] up to seven1 percent, with a company executive publicly stating that the software could be responsible for rent increases of up to 14.5 percent.
f. 1Property management software companies and landlords who use algorithmic systems that serve a coordinating function have been subject to public and private litigation for alleged violation of existing State and federal antitrust law.
g. Although the form of restraint of trade has evolved, the vital role of antitrust law in maintaining the competitive function of the free market remains.
h.1 New Jersey recognizes housing as a basic human need and endeavors to expand access to affordable housing.
2[2.] 3.2 As used in 1[this act] 2[P.L. , c. (C. ) (pending before the Legislature as this bill)1] this act2:
1"Affordability controls" means a restriction on rent price established pursuant to a government program, including but not limited to: the federal section 8 Housing Choice 2[programs, authorized pursuant to Title 42 of the Code of Federal Regulations] Voucher Homeownership Program, authorized pursuant to Subpart M of Part 982 of Title 24 of the Code of Federal Regulations (24 CFR 982.601 et seq.)2; P.L.2004, c.140 (C.52:27D-287.1 et seq.); the "Fair Housing Act," P.L.1985, c.222 (C.52:27D-301 et al.); any program administered by the New Jersey Housing and Mortgage Finance Agency; a rent control or rent levelling ordinance; or other local, State 2,2 or federal government housing program.1
2"Algorithmic device" means a device that uses one or more algorithms to process or otherwise perform calculations of data, including but not limited to, data concerning rental prices, material lease terms, or occupancy levels. An algorithmic device does not include: (1) a spreadsheet that (a) operates without artificial intelligence and (b) requires human analysis to process or otherwise perform calculations of data; or (2) a database that only uses an algorithm to query unprocessed data stored on or within that database.
"Competitively sensitive information" means nonpublic information including, but not limited to, prices, supply levels, security deposits, ideal occupancy levels, lease contract termination, renewal dates of residential dwelling units, or any other material lease terms.2
"Coordinating function" means:
(1) collecting 2[historical or contemporaneous prices, supply levels, or lease or rental contract termination and renewal dates of residential dwelling units from two or more rental property owners] the competitively sensitive information of two or more rental property owners for the purpose of analyzing or processing information through the use of an algorithm or other automated process, including by using the information to train an algorithm, where the algorithm or other automated process is used to set or recommend rental prices, material lease terms, or occupancy levels2;
(2) 2[analyzing or processing of the information described in paragraph (1) of this definition through use of a system, software, 1algorithm,1 or 1other automated1 process that uses computation, including by using the information to train an algorithm; and] setting rental prices, material lease terms, or occupancy levels pursuant to an underlying algorithm or other automated process that analyzes or processes competitively sensitive information of any other rental property owner, including by using that competitively sensitive information to train an algorithm; or2
(3) 2[recommending rental prices, lease renewal terms, or ideal occupancy levels to a rental property owner] setting for or recommending to two or more rental property owners: rental prices, material lease terms, or occupancy levels pursuant to the same or a substantially similar underlying algorithm or other automated process, that facilitates parallel pricing coordination.
"Coordinating function" shall not include the following:
(1) providing, using, or collecting competitively sensitive information solely for the purpose of conducting research, statistical analysis, or testing, where the competitively sensitive information is not used in setting or recommending rental prices, material lease terms, fees, occupancy rates or levels, or other contract terms for current or future leases;
(2) developing an estimated amount of rent that is made available to the public at no cost;
(3) the use of a real estate brokerage database that is available on equal terms to subscribers that lists properties for rent or sale but does not:
(a) set or recommend rental prices, material lease terms, or occupancy rates or levels; or
(b) collect competitively sensitive information to set or recommend rental prices, material lease terms, or occupancy rates or levels; or
(4) a government entity setting or limiting rents or sale prices of residential property through affordability controls in accordance with the law2.

2"Nonpublic information" means information that is not available to the public at no cost. In instances where the information is combined with public information, all combined information shall be deemed nonpublic information.2
"Person" means, unless the context 2[otherwise]2 requires 2otherwise2, any natural person or persons, or any corporation, partnership, company, trust, or association of persons.
2"Parallel pricing coordination" means a tacit or express agreement between two or more rental property owners to raise, change, maintain, or manipulate pricing for the leasing of reasonably interchangeable residential dwelling units, unless required to do so in accordance with affordability controls. This includes agreements between a coordinator and multiple property owners.
Rental property owner" means a person that owns, directly or indirectly, one or more rental residential dwelling units. Any person that holds a controlling interest in an entity that owns a rental residential dwelling unit shall be deemed to constitute a single rental property owner with that entity.2
