DENVER, CO - The House today advanced legislation on a preliminary vote that would bring down costs for Coloradans by cracking down on rent algorithms that drive up housing prices.
“Price fixing is wrong, anti-competitive, and costly for hardworking Coloradans who are already struggling to pay their bills,” said Rep. Steven Woodrow, D-Denver. “New price-setting rental algorithms have increased annual housing costs by $1,600 in Denver. Coloradans deserve better. With this legislation, Colorado Democrats are making Colorado a more affordable place to live by cracking down on this unjust practice and saving renters money on housing.”
“The Biden Administration clearly stated that rent algorithm schemes violate anti-trust laws, so we’re taking action in Colorado to end these illegal practices to save Colorado renters money,” said Rep. Javier Mabrey, D-Denver. “For too long, corporate landlords have colluded together to drive up housing prices to pad their pockets, and we’re here to say enough is enough. This legislation stands up against bad actors to enforce our anti-trust laws, protecting hardworking Coloradans from predatory practices and saving them over $1,600 a year.”
HB25-1004 would save Coloradans money on housing by restricting the sale or distribution of an algorithmic device with the intent that it be used by two or more landlords in the same or related market when setting a rent price.
A recent report found that coordinated rents from algorithmic pricing increase rent prices by $136 per month for Denver renters, or close to $1,600 per year. In recent years, several lawsuits have been filed alleging that the use of algorithmic devices by landlords to set prices and other commercial terms in the residential housing market results in higher rents and a constrained housing supply for residential tenants.
In January 2025, Colorado joined a federal lawsuit to sue six of the largest landlords in the US for participating in algorithmic pricing schemes that harm renters. Colorado Attorney General Phil Weiser also joined a federal lawsuit in August 2024 against RealPage, Inc. for allegedly using illegal agreements with landlords to carry out a price-fixing scheme that has cost Coloradans millions of dollars in rent payments.
