The complaint filed Thursday charges that the country’s largest landlord failed to include information about numerous mandatory fees in its listings.

The U.S. Federal Trade Commission has filed a lawsuit accusing property management company Greystar of swindling renters across the country out of at least $100 million using hidden fees.

The Federal Trade Commission and the State of Colorado filed a complaint against the rental property manager alleging it has added hidden fees since at least 2019 that cost consumers hundreds of millions of dollars.
