Colorado · SPD19Colorado Seller's Property Disclosure (SPD19)

In Colorado the seller – not the broker – completes the Commission's Seller's Property Disclosure, SPD19 (mandatory from January 1, 2026), to its current actual knowledge, and delivers it by the Seller's Property Disclosure Deadline in the contract (CBS1 §10.1). Known adverse material facts must be disclosed even if no line asks about them. If the seller discovers a new adverse material fact after the contract, the buyer may terminate by the earlier of closing or five days after receiving the new disclosure (CBS1 §10.2).

How the SPD works

  1. Who and when

    Completed by the seller, not the broker, to the seller's current actual knowledge as of the Seller's Property Disclosure Deadline in §3.1 of the contract.

  2. Adverse facts

    A known adverse material fact affecting the property or occupants must be disclosed whether or not the form has a line for it; changes are disclosed promptly after discovery.

  3. Not a warranty

    The SPD is not a warranty by the seller or any broker and not a substitute for an inspection; the contract, not the SPD, decides what is included in the sale.

  4. New fact after contract

    Under CBS1 §10.2 the buyer may terminate on a new adverse disclosure by the earlier of closing or five days after receiving it.

What the form covers

  • Improvements: building conditions (structure, moisture, pest and casualty damage, settling), roof, appliances, electrical and telecommunications, mechanical systems.
  • Water: general information and the source of water and water supply – including whether a well permit is provided; sewer and septic; flooding and drainage.
  • General: use, zoning and legal issues; access and parking; environmental conditions (including past use as a methamphetamine lab).
  • Radon: tests, detected concentrations or mitigation, and any mitigation system.
  • Common interest community and metropolitan district information.

What the TC tracks

  • The Seller's Property Disclosure Deadline in §3.1 – and that the current SPD19 form is used.
  • Copies of radon reports, well permit and any attachments the seller references.
  • Any updated disclosure after contract – it opens the buyer's 5-day window.
  • The Inspection Objection Deadline that usually follows the SPD delivery.
