Colorado Attorney General Phil Weiser and federal regulators filed a joint lawsuit against the largest apartment owner in the country on Thursday, accusing it of intentionally misleading tenants about the cost of its rentals.

Colorado and the FTC say Greystar Real Estate and Property fraudulently advertises low rent prices to potential customers, only to add tens if not hundreds to the monthly rent cost with hidden fees.

While Greystar maintains it has been proactive in improving fee disclosures and promoting transparency, the company noted the lack of clear regulatory guidelines in the rental space. The potential lawsuit is part of a broader regulatory crackdown on big corporations under FTC Chair Lina Khan and President Biden's administration.
