Colorado’s real estate disclosure laws require sellers of residential property to tell buyers, in writing, about known defects and specific legal conditions before a sale closes. Most of the work happens on one document — the Seller’s Property Disclosure form issued by the Colorado Real Estate Commission — but several state statutes and one federal law add standalone requirements that the form alone does not satisfy. Missing any of them can mean damages, attorney fees, or a rescinded sale.
What Sellers Must Disclose on the State Form
The Seller’s Property Disclosure form is the centerpiece. The Colorado Real Estate Commission approves and updates it, and the current version, mandatory for use as of January 1, 2026, asks sellers to answer detailed questions based on their actual knowledge of the property.1Colorado Real Estate Commission. Seller’s Property Disclosure (Residential) The form itself warns that failing to disclose a known adverse material fact can result in legal liability.
Sellers answer each item “Yes,” “No,” or “Don’t Know,” and must explain every “Yes.” The questions cover:
- Building conditions: structural problems, foundation issues, roof leaks, and any reinforcements added.
- Systems: electrical, telecommunications, plumbing and sewer, heating and ventilation, and water supply.
- Appliances included in the sale.
- Environmental conditions: asbestos, radon, methane, pesticides, petroleum products, underground storage tanks, mine shafts, and whether the property sits in a floodplain, wetland, or geological hazard area.2Colorado Division of Real Estate. Seller’s Property Disclosure (Land)
- Legal and zoning issues: building code violations, restrictive covenant violations, boundary disputes, encroachments, pending litigation, and any part of the property leased to others.
One point about radon deserves attention because Colorado has some of the highest radon levels in the country. Sellers only have to disclose what they actually know. A home that has never been tested produces nothing to disclose, so buyers who want radon data need to arrange testing during their own inspection period.
Disclosures the Form Alone Doesn’t Cover
Several Colorado statutes require separate disclosures with their own language, formatting rules, and penalties. Completing the standard form does not check these boxes.
Special Taxing Districts
Under C.R.S. § 38-35.7-101, every residential purchase contract must include a bold-faced warning that the property may sit within a special taxing district carrying general obligation debt. The notice tells buyers that owners in such districts face the risk of increased mill levies and taxes if the district cannot service its debt, and directs them to the county treasurer and the certificate of taxes due.3Justia. Colorado Code 38-35.7-101 – Disclosure – Special Taxing Districts – General Obligation Indebtedness Metropolitan districts around the state can carry substantial debt that translates into property tax bills far higher than a home’s purchase price would suggest.
A seller who omits the disclosure owes the buyer all resulting damages plus court costs.3Justia. Colorado Code 38-35.7-101 – Disclosure – Special Taxing Districts – General Obligation Indebtedness
Common Interest Communities
If the property lies within a common interest community such as a homeowners association, C.R.S. § 38-35.7-102 requires a bold-faced disclosure in the contract informing the buyer that they will have to join the association, pay assessments, and comply with the declaration, bylaws, and rules. The notice specifically warns that unpaid assessments can lead to a lien and a forced sale.4Justia. Colorado Code 38-35.7-102 – Disclosure – Common Interest Communities On request, the seller must also provide or authorize the association to provide governing and financial documents.
A missing HOA disclosure entitles the buyer to actual damages plus court costs. The seller has a statutory affirmative defense, though: if the buyer already had actual or constructive knowledge of the HOA and its obligations, no claim survives.4Justia. Colorado Code 38-35.7-102 – Disclosure – Common Interest Communities
Source of Drinking Water
C.R.S. § 38-35.7-104 requires sellers to identify the property’s drinking water source in the listing contract, sales contract, or property disclosure. The disclosure must state whether the water comes from a well, a water provider, or another source, and give the provider’s contact information. It also carries an advisory that some providers rely to varying degrees on nonrenewable groundwater, and it points buyers toward the provider for questions about long-term sufficiency.5Justia. Colorado Code 38-35.7-104 – Disclosure of Potable Water Source – Rules
If the source is a well, the seller must supply a copy of the current well permit when available. A seller who complies is shielded from any buyer claim for damages based on an alleged inadequacy of the water source.5Justia. Colorado Code 38-35.7-104 – Disclosure of Potable Water Source – Rules
Methamphetamine Contamination
C.R.S. § 38-35.7-103 requires a seller who knows the property was previously used as a methamphetamine lab to disclose that fact to the buyer in writing.6Justia. Colorado Code 38-35.7-103 – Disclosure – Methamphetamine Laboratory The buyer can test for contamination; if results show contamination that has not been remediated to state health standards, the buyer can give written notice and terminate the contract, and the seller then has 30 days to conduct a second independent test.
A seller who conceals a known meth history faces liability for remediation costs, health-related injuries to residents caused by the contamination, and reasonable attorney fees. The buyer has three years from closing to file suit.6Justia. Colorado Code 38-35.7-103 – Disclosure – Methamphetamine Laboratory A property that has been remediated to state Board of Health standards and received a certificate of compliance no longer triggers the disclosure requirement; five years after certification, it comes off the state database of former labs.
Lead-Based Paint in Pre-1978 Homes
Federal law layers onto the state requirements for older homes. Under the Residential Lead-Based Paint Hazard Reduction Act of 1992 (Title X), sellers of any home built before 1978 must, before the buyer becomes obligated under a purchase contract, do three things:7Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property
- Give the buyer an EPA-approved lead hazard information pamphlet.
- Disclose any known lead-based paint or lead hazards and hand over any available inspection reports.
- Offer the buyer a 10-day window to arrange a lead paint inspection or risk assessment, though the parties can agree to a different timeframe.
The contract itself must contain a Lead Warning Statement, and the buyer must sign confirming they got the pamphlet and the inspection opportunity. Penalties fall under the Toxic Substances Control Act. The base figure in the regulation is $11,000 per violation, subject to periodic inflation adjustments that have raised it substantially, and sellers can also face civil damages.8eCFR. 40 CFR 745.118 – Enforcement
What a Buyer Can Do When a Seller Stays Silent
The strongest remedy is rescission. A buyer who uncovers material misrepresentations or undisclosed defects before or shortly after closing may be able to unwind the sale entirely, walking away with their money rather than the problem.
More often, buyers sue for damages after they own the house. Colorado courts recognize claims for both fraudulent misrepresentation (the seller lied) and fraudulent concealment (the seller stayed silent about something they knew). A successful claim can recover repair costs, the property’s diminution in value, and related expenses.
The statutory disclosures carry their own remedies on top of common-law claims. A missing special taxing district or HOA disclosure gets the buyer actual damages plus court costs.3Justia. Colorado Code 38-35.7-101 – Disclosure – Special Taxing Districts – General Obligation Indebtedness Concealed meth contamination gets remediation costs, health-injury damages, and attorney fees.6Justia. Colorado Code 38-35.7-103 – Disclosure – Methamphetamine Laboratory
Whether a buyer’s recovery is capped at liquidated damages (a pre-set amount) or extends to full actual damages turns on how the purchase contract is drafted. Colorado courts have confirmed that a contract can give the buyer the option to choose between the two, so contract language matters. Read the contract carefully before assuming the recovery is limited.
How Long Buyers Have to Sue
Colorado applies a three-year statute of limitations to claims for fraud, misrepresentation, concealment, and deceit, running from the date the claim accrues.9Justia. Colorado Code 13-80-101 – General Limitation of Actions A claim usually accrues when the buyer discovers the problem or reasonably should have discovered it. That can be well after closing when a defect stayed hidden.
The meth disclosure statute uses a different clock. Its three years run from the closing date itself, not from discovery.6Justia. Colorado Code 38-35.7-103 – Disclosure – Methamphetamine Laboratory A buyer who finds contamination four years in has lost the statutory remedy regardless of when they learned about it.
These deadlines are strict. If you suspect a seller hid something, get legal advice quickly rather than waiting to see how bad the problem becomes.
When “I Didn’t Know” Works — and When It Doesn’t
Colorado’s disclosure obligations turn on what the seller actually knew at the time of sale. A seller who genuinely did not know about a defect is generally not liable for failing to disclose it, and the state form reflects this by allowing “Don’t Know” as an answer.1Colorado Real Estate Commission. Seller’s Property Disclosure (Residential)
Ignorance is not a magic shield, though. If the evidence shows the seller should have known, or deliberately avoided finding out, a court may reject the defense. A seller who received a home inspection report flagging a defect and then marked “No” or “Don’t Know” on the disclosure form will have a hard time in front of a judge.
Broker and Agent Duties
Real estate brokers and agents carry their own disclosure obligations that run alongside the seller’s. In every transaction, a broker must disclose known adverse material facts to all parties, regardless of which side the broker represents.10Justia. Colorado Code 12-10-217 – Investigation – Revocation – Actions Against Licensee or Applicant – Definition An adverse material fact is one a reasonable person would consider significant and that cuts against the interests of a party. The Colorado Real Estate Commission has said this includes facts affecting structural integrity, documented environmental health risks, and matters affecting title or occupancy. Practical examples include zoning violations, water damage from marijuana grows, damage from insect infestation or expansive soils, and liens.
The duty is limited to facts the broker actually knows. There is no obligation to independently investigate or verify the seller’s disclosures. But a broker who learns of a problem and stays quiet faces discipline: the Commission can impose an administrative fine of up to $2,500 per offense, censure the licensee, place them on probation, or suspend or revoke the license.10Justia. Colorado Code 12-10-217 – Investigation – Revocation – Actions Against Licensee or Applicant – Definition A consumer can start the process by filing a complaint with the Division of Real Estate.11Colorado Division of Real Estate.
