Senate Bill 1990, known as the "Stop Rent Rigging Act," aims to address the manipulation of rental prices in Tennessee. The bill introduces new definitions and regulations regarding the use of algorithms and algorithmic devices by residential rental property owners and managers. Specifically, it defines terms such as "algorithm," "algorithmic device," and "coordinating function," and establishes that it is unlawful for individuals or entities to facilitate agreements that restrain competition among rental property owners or to set rental prices based on algorithmic recommendations.

The bill stipulates that knowingly or recklessly engaging in such practices constitutes an unlawful restraint of trade or commerce, subjecting violators to civil and criminal penalties equivalent to those outlined in existing law. The act is set to take effect on July 1, 2026, emphasizing the importance of fair competition in the rental market and protecting consumers from potential price manipulation.
