THIRTY-THIRD LEGISLATURE, 2025

STATE OF HAWAII

A BILL FOR AN ACT

RELATING
TO ANTITRUST
.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF HAWAII:

����
SECTION 1.
�

The legislature finds and declares that Hawaii is in the midst of
an affordable housing crisis, with the highest median rent in the nation.
�
Data shows that more than half of renters in
Hawaii are housing cost burdened, which means an individual spends more than
thirty per cent of income on rent.

����
The legislature further finds that
recent national data indicates that landlords of residential rental housing use
property management software to collude and raise residential rental housing
prices, which may have contributed to recent increases in the State.
�
Landlords engaging with the property
management 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 rental prices typically increase.

����
The legislature acknowledges that 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 two to five per cent, with a
company executive publicly stating that the software could be responsible for
rent increases of up to 14.5 per cent.

����
Therefore, the purpose of this Act
is to prevent artificially inflated rental prices by prohibiting the use of
algorithmic price-setting in Hawaii's rental market.

����
SECTION 2.
�
Chapter 480, Hawaii Revised Statutes, is
amended by adding a new section to be appropriately designated and to read as
