Colorado Seller Disclosures: What You're Required to Tell Buyers
Most sellers focus on staging, pricing, and finding the right agent. Almost none of them think about what happens after closing — until a buyer's attorney calls. Failing to disclose a known defect in Colorado can expose you to a lawsuit long after you've moved on, cashed the check, and started your next chapter.
This isn't meant to scare you. It's meant to make sure you're protected. Here's exactly what Colorado requires you to disclose — and what sellers commonly miss.
Key Takeaways
- Colorado uses a standard form called the Seller's Property Disclosure (SPD19) — every seller fills one out
- Colorado is a "caveat emptor" state, but you're still legally required to disclose known material defects
- The most commonly missed items: radon, past water damage, and HOA issues
- Failing to disclose can result in legal action even after closing
- Radon is especially worth testing — Colorado has some of the highest levels in the US
What Colorado Law Actually Requires
Colorado is technically a "caveat emptor" (buyer beware) state — but that doesn't mean sellers are off the hook. Under Colorado law, you're required to disclose any known material defects that would affect the buyer's decision to purchase or the price they'd pay.
The vehicle for this is the Seller's Property Disclosure form, or SPD19 — a standardized document regulated by the Colorado Division of Real Estate. It's not optional. Your agent will walk you through it, but you're the one signing it.
The SPD19 covers a wide range of property conditions. Here's what you're expected to address:
- Structural issues — foundation problems, roof damage, settlement
- Water damage and moisture — past flooding, leaks, drainage problems
- Mold — any known presence, past or present
- Radon levels — whether you've tested, and what the results were
- Lead paint — required for all homes built before 1978 (federal law)
- Pest infestations — termites, rodents, or other known infestations
- HOA information — dues, rules, pending assessments, violations
- Boundary disputes — any known encroachments or easement conflicts
- Environmental hazards — underground tanks, contamination, proximity to hazardous sites
The Big Ones Sellers Miss
Most sellers do fine with the obvious stuff — a cracked foundation or a bad roof isn't something you forget. It's the subtler items that get people in trouble.
Past Water Damage
That basement that flooded five years ago and was fully remediated? Still needs to be disclosed. The fact that it was fixed is good news for the buyer — but they need to know it happened. Courts have ruled against sellers who assumed "repaired = not disclosable."
HOA Issues
If your HOA has a pending special assessment, an ongoing dispute with residents, or outstanding violations on your unit, those need to be in the disclosure. Buyers often find out about HOA problems after closing — and blame the seller.
Neighborhood Nuisances
You know that neighbor with the dogs that bark until midnight, or the commercial property across the street that runs deliveries at 5 AM? Colorado law doesn't always require you to disclose these, but they're the kinds of things that end up in nasty buyer-seller disputes. When in doubt, mention it.
Radon: Colorado's Hidden Problem
This one deserves its own section because Colorado sellers consistently underestimate it.
Colorado has some of the highest radon concentrations in the United States, driven by the state's geology — uranium-rich granite and soil. The EPA recommends testing if a home hasn't been checked recently, and for good reason: elevated radon is the second leading cause of lung cancer in the US.
If you've never tested your home for radon, do it before listing. A test costs around $15-$25 for a DIY kit, or $100-$200 for a professional test. If levels come back at or above 4 pCi/L (the EPA's action level), mitigation typically runs $800–$2,500 — and it's a straightforward fix that won't derail your sale.
What Happens If You Don't Disclose
Sellers sometimes gamble that buyers won't find out. They often do — and when they do, the consequences range from uncomfortable to expensive.
In Colorado, a buyer who discovers an undisclosed defect after closing can pursue the seller for:
- The cost to repair the defect
- Diminished property value
- In some cases, rescission of the entire sale
There's no "safe harbor" period after which you're in the clear. If a buyer discovers two years after closing that you knew about water intrusion and didn't disclose it, you can still be sued. Colorado courts have consistently sided with buyers in these cases when sellers had clear knowledge of a defect.
The math here is pretty simple: the cost of disclosure is zero. The cost of a non-disclosure lawsuit can run into the tens of thousands.
If you're still figuring out the right time to list, it's worth reading whether now is a good time to sell in Colorado — and once you're ready, how to price your home right in today's market.
Frequently Asked Questions
Do I have to disclose defects that were already repaired?
Generally, yes. Colorado expects sellers to disclose known material defects, including ones that have since been fixed. Disclosing a repaired issue — along with documentation of the repair — is actually in your favor. It shows transparency and reduces the chance of a dispute later.
What if I genuinely didn't know about a defect?
You can only disclose what you know. The SPD19 asks about known conditions — you're not expected to be a home inspector. However, if there are signs of a problem you clearly should have noticed (visible water stains, obvious foundation cracks), "I didn't know" becomes harder to defend. A pre-listing inspection can protect you here.
Is the seller's disclosure the same as a home inspection?
No — they serve different purposes. The SPD19 is your statement of what you know about the property. A home inspection is a professional assessment of what a licensed inspector finds. Buyers almost always order their own inspection, and discrepancies between your disclosure and the inspection report can raise red flags. Being thorough on the SPD19 keeps you out of that conversation.
Bottom Line
Colorado's disclosure requirements aren't designed to make selling harder — they're designed to protect everyone involved. Fill out the SPD19 honestly, test for radon if you haven't recently, and don't assume that a fixed problem is a forgotten one. A clean, transparent disclosure is one of the best things you can do to protect your proceeds and your peace of mind after closing.
