3.2 Colorado Seller Disclosure Requirements

Colorado is not a strict caveat emptor state. A seller and the seller's broker each have legal duties to disclose known adverse material facts about the property. Understanding exactly what the law mandates - versus what is merely a recommended Commission form - is a frequent exam distinction that trips up candidates who memorize a list of "required forms" without reading the statute carefully.

The Seller's Property Disclosure (SPD) Form

The Commission publishes a standardized Seller's Property Disclosure (Residential) form. A common misconception - and a wrong statement in many study guides - is that Colorado requires the SPD by statute. It does not. Use of the SPD form itself is not mandated by statute; what is mandated, through Colorado case law (the seminal duty-to-disclose decisions) and the broker's brokerage-relationship duties, is the obligation to disclose known latent (hidden) defects that materially affect the property.

In practice nearly every residential seller completes the SPD because it is the cleanest way to document those disclosures, reduce later litigation, and show good faith; brokers routinely have sellers complete it as a matter of standard practice.

The SPD is the seller's statement of actual knowledge, organized by system. It is a disclosure of what the seller knows - not a warranty that the systems are in good condition:

What the seller must do

• Complete the form honestly, to actual knowledge (not a warranty of condition)
• Update the disclosure if new information arises before closing (a defect discovered after the SPD was signed but before closing must be added)
• Disclose known latent material defects even if the buyer never asks
• Never actively conceal a defect - painting over a water stain, caulking a crack to hide it, or hiding a foundation problem behind storage is affirmative concealment and is actionable fraud

"Limited-knowledge" sellers

Banks selling REO (real-estate-owned) property, personal representatives of estates, and trustees in court-ordered sales often have no personal knowledge of the home and may note that limited knowledge on the form. They are still prohibited from concealing or misrepresenting anything they do actually know - limited knowledge is not a license to hide a known defect.

Material defect = a condition that substantially affects value, impairs health or safety, or would change a reasonable buyer's decision, and is not readily observable on an ordinary walkthrough.

The Broker's Independent Disclosure Duty

A Colorado broker's duty to disclose is separate from the seller's and does not depend on what the seller chooses to disclose. Under Commission rules and the brokerage-relationship statute, a broker - including a transaction-broker who owes no fiduciary loyalty to either side - must disclose adverse material facts actually known to the broker about the property's condition, title, or environment. This duty is owed in every Colorado relationship, which is why the seller-disclosure topic ties directly back to agency law.

The line is actual knowledge: a broker is not a guarantor of the property's condition and has no duty to investigate or inspect, but cannot stay silent about a defect they actually know of. A worked example: if a listing broker walks the basement and sees an active water leak the seller left off the SPD, the broker must disclose it to buyers even at the risk of losing the listing. "I was only the transaction-broker" is not a defense, because the disclosure duty does not depend on agency status.

Federal Lead-Based Paint Disclosure (Pre-1978)

This federal rule applies in every state, including Colorado, to target housing built before 1978:

Colorado-Specific Disclosures

• Carbon monoxide alarms (C.R.S. 38-45-101 et seq.): Since July 1, 2009, any single- or multi-family dwelling that is sold, remodeled, or leased to a new tenant and that has a fuel-fired appliance, a fireplace, or an attached garage must have CO alarms installed within 15 feet of each bedroom entrance. This is a true statutory mandate, not a mere recommendation, and is a favorite exam detail because of the specific 15-foot distance and the three triggering features.
• Methamphetamine contamination: If the seller knows the property was used to manufacture meth, it must be disclosed; cleanup must meet state decontamination standards before re-occupancy. An undisclosed known meth history is an adverse material fact.
• Radon: Colorado has some of the nation's highest radon levels, and the EPA action level is 4.0 pCi/L. Testing and disclosure are strongly recommended; the standard CBS contract now includes a radon advisory and gives the buyer a right to test.
• Source of water / well permit, and HOA status are disclosed on the SPD and confirmed in the contract; a well typically requires a well permit, and the buyer should verify it.

Exam trap: "Colorado requires the SPD form by statute" is false. The duty to disclose known latent material defects is mandatory; the form is the Commission's recommended tool. Contrast that with the CO-alarm rule, which is a true statutory mandate.
