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

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.
