Relating to: algorithmic software for residential housing, and providing a penalty.

AB 142 prohibits landlords and software providers from using algorithmic software to set rents or occupancy rates based on private competitor data (like unpublicized rent or occupancy details). It directly affects residential landlords, property management companies, and software vendors selling such tools. The bill bans both selling/licensing the software and using it for rent decisions, with penalties of up to $1,000 per violation per rental unit. Tenants may also sue for damages or injunctive relief, while exemptions cover aggregated rental data publications and affordable housing tools.
