Gov. Jared Polis has signed a bill that takes aim at what sponsors charged are “hidden fees” in rental agreements.

House Bill 1090, sponsored by Reps. Emily Sirota, D-Denver, and Naquetta Ricks, D-Aurora, and Sens. Mike Weissman, D-Aurora, and Lisa Cutter, D-Littleton, will require sellers to disclose the maximum “total price” of a good or service, including any additional charges or fees.

Sponsors claimed that landlords are some of the biggest offenders when it comes to imposing so-called “junk fees,” which they described as additional charges for anything from pest control to valet garbage services to vague “convenience fees.”

Cutter said these charges are sometimes not disclosed to tenants until they have signed their lease.

“For some, these surprise changes are frustrating,” she said during a news conference in January. “For others, they can mean the difference between making rent and putting food on the table. These hidden charges don’t just hurt individual consumers, they undermine trust and prevent a fair, competitive marketplace where people can compare prices and make informed decisions.”

The issue has also sparked legal action.

Colorado and the Federal Trade Commission have filed a lawsuit against the nation’s largest landlord for failing to disclose mandatory fees that increased the true cost of rent by an additional $1,700 a year.
