What Colorado Sellers Must Disclose (and What They Don't)

Every seller eventually asks some version of the same question: do I really have to tell them about that? The old roof leak that's been fixed for three years. The basement that took on water once during a hundred-year storm. The neighbor dispute that finally settled down. The instinct to keep quiet is understandable — you don't want to scare off a buyer or invite a price cut. But in Colorado, disclosure isn't just an ethical nicety; it's a legal obligation, and misjudging it is one of the fastest ways for a seller to turn a closed sale into a lawsuit.

Colorado Is a "Material Defect" Disclosure State

The governing principle in Colorado is straightforward: sellers must disclose known material defects — latent physical conditions that could adversely affect the property's value or a buyer's use of it and that a buyer wouldn't readily discover on their own. "Latent" is the key word. If a defect is obvious — a visibly cracked window, a missing railing — a buyer is presumed to see it. It's the hidden problems, the ones you know about but a reasonable buyer wouldn't spot, that the law requires you to reveal.

In practice, most Colorado sellers make these disclosures using the standard Seller's Property Disclosure form, a detailed questionnaire produced by the Colorado Real Estate Commission. It walks through the property system by system — roof, foundation, plumbing, electrical, HVAC, appliances, sewer and septic, water source, and more — asking what you know about the condition of each. It's not a warranty and it's not a substitute for the buyer's inspection. It's a record of what you, the seller, actually know.

What You Have to Disclose

The list is broad, but a few categories come up again and again along the Front Range. You must disclose known structural and foundation issues — and given Colorado's expansive clay soils, foundation movement, cracks, and prior repairs are common and squarely disclosable. You must disclose known water intrusion or drainage problems, including past flooding or a basement that has taken on water, even if you believe it's fixed. Roof leaks and prior roof damage — hail country makes this a frequent one — belong on the form. So do known problems with major systems (furnace, water heater, electrical panel, sewer line), the presence of known environmental hazards, and the results of tests you've had done. If you've tested for radon, for instance, and it came back high, that result is a known condition. You don't have to test, but you can't hide a test you have.

You should also disclose known issues that aren't strictly physical but affect the property — an unpermitted addition or finished basement, an easement or encroachment you're aware of, pending litigation involving the property, or unresolved insurance claims. When in doubt, the safe move is almost always to disclose.

What You Generally Don't Have to Disclose

Colorado law also protects seller privacy in specific areas, and this is where sellers often over-worry. Under Colorado statute, you are not required to disclose that a death occurred on the property — whether by natural causes, suicide, or homicide. Nor are you required to disclose that a prior occupant had a condition such as HIV or AIDS. The law treats these as "psychologically stigmatizing" facts that are not material defects, and it explicitly shields sellers from liability for not disclosing them. (You still can't lie if directly asked in a way that involves fraud, but you have no affirmative duty to raise them.)

You're also generally not obligated to disclose the state-registered status of a nearby sex offender — buyers are directed to the public registry to research that themselves — and you don't have to volunteer subjective opinions about the neighborhood, the neighbors' personalities, or the quality of the schools. Facts about the physical property you disclose; opinions and stigmas you generally needn't.

"Fixed" Does Not Mean "Forget It"

This is the single most common place sellers get into trouble. A problem that has been genuinely repaired is still a known past condition, and the honest approach — and the legally safer one — is to disclose the issue and the repair together. "Basement took on water in the 2023 storm; installed a new sump pump and regraded the yard; no recurrence since" is a disclosure that protects you. Saying nothing, and having the buyer discover the old water line on the basement wall six months later, is how you end up defending a nondisclosure claim. Disclosing a fixed problem, with documentation of the fix, frequently reassures buyers rather than scaring them — it shows the issue was handled competently.

Why Silence Is the Expensive Choice

Colorado buyers who discover an undisclosed material defect after closing have real legal remedies, including claims for fraudulent concealment and misrepresentation. The exposure isn't limited to the cost of the repair — it can include the buyer's legal fees, and in cases involving genuine fraud, additional damages. Weigh that against the alternative: a disclosure that might, at worst, prompt a modest price negotiation or a repair request you can address during the transaction, on your terms, while you still control the outcome. Almost every experienced agent has watched a seller trade a small, manageable concession during the deal for a large, unmanageable liability afterward — purely by staying quiet.

The Bottom Line

Colorado's rule rewards honesty and punishes concealment, and the line is more favorable to sellers than the instinct to hide suggests. Disclose known material defects — especially the Front Range classics of foundation, water, and roof — disclose the repairs alongside the problems, and rest easy on the privacy protections the law genuinely gives you around deaths and stigmas. When you're unsure whether something rises to the level of disclosable, that's exactly the conversation to have with your agent before the form goes out, not after the buyer's attorney calls. At Emblem, we'd rather spend an hour getting a disclosure right than a year helping a client untangle the alternative.
