What Should I Know About Construction Warranties?

The most common misconception about residential construction warranties is that there is one warranty, and the homeowner has read it. There are usually three, sometimes four, and they operate on different timelines, cover different things, and produce different remedies. The builder's express warranty is one of them; in Colorado it is not necessarily the most important one. This article is a map of the warranties a typical new-home buyer actually holds, and the practical question of which one to invoke first when something goes wrong.

The four warranties in play

In a typical Colorado new-home purchase, the following warranties can apply at the same time:

1. The builder's express warranty. This is the document the buyer signs at closing — sometimes one or two pages, sometimes a thick booklet with elaborate exclusions and a binding-arbitration clause.

2. The implied warranty of habitability and workmanlike construction. Colorado common law recognizes implied warranties that run from a builder-vendor to the original purchaser of a new home, independent of anything in writing. The doctrine has long roots in Colorado decisional law and is one of the more useful tools when the express warranty is narrow.

3. The product manufacturer warranties. Windows, HVAC equipment, roofing materials, appliances, plumbing fixtures, and many other installed products carry their own manufacturer warranties, sometimes for substantially longer than the builder's warranty. These are often missed because the documents arrive in the construction-closeout binder and are never read again.

4. Third-party warranty programs. Some builders enroll their homes in third-party warranty plans — typically structured as one-year workmanship, two-year systems, ten-year structural coverage — administered by an outside company. When one of these is in place, the homeowner has rights against the warranty administrator in addition to the builder.

The first practical step when a defect appears is figuring out which of these four are actually in your file. Buyers often discover that they have all four, or three of the four, and that they have only read the first.

Reading the express warranty

When I read a builder's express warranty for a new client, I am looking at four things in order:

• Duration of coverage by category. Most express warranties tier coverage by element — one year on workmanship and finishes, two years on mechanical and electrical systems, ten years on major structural. The categories are not standardized; the warranty's own definitions control.

• What is excluded. This is where the document does its real work. Exclusions for "consequential damage," "cosmetic conditions," "wear and tear," "homeowner-caused damage," and "matters covered by manufacturer warranties" can swallow a lot of what a homeowner would otherwise consider covered.

• Notice and inspection procedure. Most express warranties require written notice within a specified window after discovery, and they reserve the builder's right to inspect before any repair occurs. Missing the notice procedure can void coverage even when the underlying defect is clearly within the warranty's scope.

• Dispute resolution clause. Most express warranties now include arbitration provisions, and many of those provisions are enforceable in Colorado under the Federal Arbitration Act. The arbitration clause changes the entire economics of the case if it controls — which is a reason to read it carefully before invoking the warranty in any formal sense.

The implied warranty, in plain English

The implied warranty is the unwritten backstop. Colorado law has long held that a builder-vendor who sells a newly constructed home to a residential purchaser impliedly warrants that the home is habitable and was constructed in a workmanlike manner. The doctrine arose because contracts of sale rarely said anything useful about quality, and courts concluded that some baseline quality obligation had to be assumed in the transaction.

In practice, the implied warranty does several useful things the express warranty often does not:

• It survives the express warranty's expiration in some circumstances, particularly for latent defects that could not reasonably have been discovered during the express-warranty period.

• It is not bound by the express warranty's exclusion of consequential damages, so it can support recovery of resulting damage that the express document tried to disclaim.

• It can be asserted against the original builder-vendor by the original purchaser without regard to whether the express warranty has been honored.

The implied warranty has limits — it does not typically run to subsequent purchasers, and it can be waived by sufficiently clear contract language — but it is a meaningful additional source of rights that the closing-day binder does not advertise.

CDARA does not replace warranties; it routes them

The Construction Defect Action Reform Act at C.R.S. § 13-20-803.5 is sometimes described as a warranty statute. It is not. CDARA is a procedural statute that requires written notice and an inspection-and-cure opportunity before a homeowner can sue a construction professional for defects. It applies regardless of whether the homeowner is invoking the express warranty, the implied warranty, or both. In other words, CDARA is the procedural overlay; the warranties are the substantive rights underneath it.

The practical implication is that a homeowner who wants to claim under any warranty, express or implied, should generally also send a CDARA notice of claim. The notice triggers the builder's inspection rights, it preserves the homeowner's litigation options if the response is inadequate, and it documents the timing of the claim — which matters for both the express warranty notice clock and the statute of limitations.

The statute-of-limitations problem

Warranties have their own internal time limits, but the underlying claims also live inside Colorado's general construction statute of limitations and repose. Under C.R.S. § 13-80-104, a claim arising from a defect in an improvement to real property must generally be brought within two years of discovery, with an outside statute of repose that cuts off claims six years after substantial completion (with a narrow two-year extension if the defect manifests in years five or six). Warranty contract language can sometimes shorten these periods further but cannot, as a general matter, extend them.

The interaction of the express warranty's notice deadline, the implied warranty's discovery rule, and the statutory clock is technical. The conservative habit is: at the first sign of a defect that may be warranty-covered, give written notice immediately, regardless of which warranty you ultimately rely on. Notice almost never hurts the case; delay almost always does.

Which warranty to invoke first

A short heuristic: invoke the express warranty first if the defect is recent and clearly within its scope, because that is the path of least resistance and the lowest cost. Invoke the implied warranty in parallel if the express warranty's exclusions are about to come into play, or if the defect is latent and the express coverage has expired. Pursue product manufacturer warranties separately when the defective element is a specific product, even if the builder's warranty would also reach it — manufacturer coverage is often longer and free to access.

And in every case where the claim might escalate beyond a phone call, send the CDARA notice. The procedural box has to be checked regardless of which substantive warranty is driving the claim.

Where to start

If you are looking at a warranty document for the first time after a defect has appeared, the most useful next step is a thirty-minute review with someone who reads these documents regularly. The express warranty alone is often the wrong starting place; what matters is the full inventory of rights in the file and the order in which they should be invoked. That conversation is short, and it usually changes the homeowner's plan in real time.
