Right now, somewhere in Denver, an algorithm is deciding whether you get a house.
Maybe it is a rental screener kicking back your application. Maybe it is a valuation model quietly shaving twenty grand off the number on your offer. Maybe it is a lead-scoring tool telling an agent you are not worth calling back. You never see it happen. You just get a no, and nobody can tell you why.
That is about to change. And most people have no idea it is coming.
On May 14, 2026, Governor Jared Polis signed SB 26-189, officially the Colorado Automated Decision-Making Technology Act. It repealed and reenacted the old 2024 Colorado AI Act and replaced it with something tighter. It is codified at C.R.S. 6-1-1701 through 1709, if you want to sound fun at a dinner party.
Here is the part people miss. The law takes effect January 1, 2027. That is roughly 63 days out from the end of October. Call it nine weeks. And it applies to what the statute calls consequential decisions made on or after that date.
So what counts as consequential? The law spells it out, and real estate is right there on the list. The exact language covers "the lease or purchase of residential real estate in Colorado," sitting alongside lending, insurance, employment, health care, and education. In other words, the stuff that decides your whole life.
Let me be specific, because this is where it gets real for anyone buying, selling, or renting on the Front Range.
Attorneys who read this thing for a living, including the folks at Frascona, flag a whole menu of covered tools. Automated valuation models, the AVMs that spit out a home's "worth." AI lead scoring. Showing-recommendation engines. Offer-analysis tools. And tenant-screening algorithms, which is the big one for renters.
Why valuations? Look at consumer AVMs for a second. One widely used home-value estimate publishes a median error of about 1.8 percent for homes already on the market, but roughly 7.2 percent for off-market homes. On a $400,000 house, that 7.2 percent is a
Here is the meat. If you are a "deployer," meaning a landlord, a property manager, a brokerage, anybody running one of these tools, you now owe people four things.
One, a clear notice before the AI is used. Two, an explanation after an adverse outcome, delivered within 30 days. Three, a right to correct bad data. Four, a path to meaningful human review.
And pay attention to that last word. Meaningful. Frascona's analysis is blunt about it. Rubber-stamping the algorithm's output does not count. A human has to actually look, actually be able to override, actually make a call. You cannot just have someone click approve on whatever the robot decided.
Deployers also have to keep compliance records for at least three years.
Now, the rewrite did soften some things. The original law's risk-management programs, impact assessments, and that broad duty of reasonable care to prevent algorithmic discrimination? All stripped out. But here is the thing that catches small operators off guard. There is no small-business exemption. None. The mom-and-pop landlord running tenant screening through some third-party platform is just as on the hook as a big management company.
Which raises the question nobody has a clean answer to yet. If you outsource your screening to an outside company and that algorithm does you dirty, who is liable? You, for using it? Them, for building it? That fight is coming.
The Colorado Attorney General has exclusive enforcement authority. No private right of action, so you cannot personally sue over it. The AG had to adopt clarifying rules on or before January 1, 2027, and already filed proposed ADMT and chatbot rules back on August 11, 2026.
Violations get treated as deceptive trade practices under the Colorado Consumer Protection Act. Penalties run up to roughly
And federal law still sits on top of all this. ECOA and FCRA do not go away. Creditors can reuse their federal adverse-action notices, but only if those notices also carry the extra stuff Colorado now demands. So the old form letter probably does not cut it anymore.
You cannot talk about this without mentioning RealPage. That is the Texas firm whose rent-setting algorithm covers more than 24 million units nationwide, and it is the poster child for the whole "should software be allowed to price your rent" debate. Colorado had a separate bill to ban algorithmic rent-setting outright. Polis vetoed it. So the pricing software lives on, but now the decisions it feeds are the ones that have to come with a notice and a human.
Meanwhile, consumer AI home tools are already running here. Symbio Homes, the brokerage out of Golden and Morrison, offers a plain-language AI home search across the Denver-area MLS plus a free online valuation. The difference going forward is accountability. The machine can still help. It just cannot hide anymore.
Nine weeks. Then the algorithm has to confess.
