A West Philadelphia renter filed a class-action lawsuit on July 28, 2026 against property manager Willow Bridge Property Co. and software vendor RealPage, alleging they used RealPage’s price-setting algorithm to coordinate rents in violation of Philadelphia’s 2025 ban on algorithmic rent-fixing. The suit is believed to be the first test of the city’s ordinance, which prohibits landlords from using software that pools competitors’ pricing data to set rents. It follows RealPage’s separate $359.9 million federal settlement over similar nationwide allegations.
