How Long Do Construction Defect Lawsuits Take in Colorado?

Eighteen months is the answer when the case goes well. Twenty-eight is the answer when it does not. Forty if the case is appealed. Those numbers are not promises — every case has its own pace — but they are the realistic range a homeowner should plan against, and they are wildly different from what most homeowners expect when they first come in.

The mismatch in expectations is the single most common source of frustration I see in this practice. A homeowner who has been told (or has assumed) that "we will be done in six months" experiences month nine as a failure. A homeowner who was told eighteen months experiences month sixteen as approximately on schedule. Same case, different framing. Here is the framing.

Phase 0: pre-litigation investigation (1 to 3 months)

The case does not begin when the complaint is filed. It begins when the homeowner first calls a lawyer, and the first thing that lawyer does is investigate. In a Colorado construction-defect case, that means engaging a forensic expert — a building science engineer, an architect, a moisture expert — to walk the property, generate a preliminary defect list, and put a preliminary number on the cost to repair.

This phase is not optional. The Construction Defect Action Reform Act at C.R.S. § 13-20-803.5 requires that the homeowner serve a "notice of claim" on the builder before filing suit, and the notice has to describe the defects "in reasonable detail" with the cost of repair "to the extent then known." That detail comes from the expert, not from the homeowner's memory of what the inspector said two years ago.

In a well-run case the investigation takes 30–60 days. In a case with significant access issues — a finished basement that has to be opened up, an exterior envelope that needs intrusive moisture testing — it can take 90 days or longer.

Phase 1: the notice of claim process (3 to 6 months)

Once the notice is served, CDARA's pre-litigation process kicks in. The builder has 30 days to acknowledge, then a 30-day inspection window, then an option to offer to repair or to pay. Each step has deadlines, and the deadlines have practical consequences: a builder who fails to respond timely loses procedural protections; a homeowner who short-circuits the process loses the ability to file suit.

In practice, the notice-of-claim process resolves a meaningful minority of cases. Where the builder makes a credible repair offer and the homeowner accepts, the timeline ends here at month four or five and the homeowner never enters court. Where the builder's offer is a fraction of the actual cost — which is the more common pattern — the process is a procedural prerequisite that adds three to six months before the lawsuit can be filed.

Phase 2: filing, pleadings, and initial discovery (3 to 6 months)

The complaint is filed; the builder answers; cross-claims and third-party complaints are filed against subcontractors, designers, and material suppliers. In a Colorado construction-defect case, the case rarely stays a two-party matter: a single defect typically pulls in three to seven additional parties, and each new party gets its own response deadline.

Initial discovery — written interrogatories, document requests, requests for admission, and the exchange of preliminary expert disclosures — runs in parallel with the pleadings expansion. Months 9 through 14 of the case clock are typically the pleadings-and-initial-discovery phase.

Phase 3: depositions and substantive discovery (4 to 8 months)

This is the longest single phase. Depositions of the named parties, the experts, the subcontractor representatives, and the relevant municipal inspectors take time to schedule and longer to take. A single deposition day is one calendar week of preparation and one calendar week of follow-up. Twenty depositions — not unusual in a multi-party defect case — is most of a year.

Expert work overlays the deposition schedule. Forensic experts conduct site inspections and moisture testing; cost-of-repair experts develop scope-and-cost documents; defense experts conduct their own inspections and write their own reports. Discovery scope-fights and protective-order disputes regularly add a month or two of motion practice.

Phase 4: mediation (often around month 18)

Most Colorado construction-defect cases mediate before trial. The court typically orders mediation as part of the case-management order, and the parties almost always comply even when the order is technically optional. Mediation is usually scheduled after substantial expert work is complete — typically 14 to 20 months into the case — so that the parties have enough information to negotiate intelligently.

Roughly two-thirds to three-quarters of construction-defect cases settle at or shortly after mediation. The remaining cases proceed to trial.

Phase 5: trial preparation and trial (4 to 8 months)

A case that does not settle at mediation enters a trial-preparation phase that is intense and expensive. Motions in limine, pretrial briefs, exhibit lists, and witness preparation occupy the four to six months before the trial date. The trial itself is generally one to three weeks of courtroom time in a defect case, though complex multi-party trials run longer.

A Colorado district-court trial date is typically set 12 to 18 months in advance, which means the trial date for a case filed today is often farther out than the trial-preparation phase requires. Courts can and do continue trial dates when the parties demonstrate that more discovery time is needed, and continuances push the timeline further.

Phase 6: post-trial and appeal (12 to 24 months, if it happens)

Post-trial motions add three to six months after the verdict. An appeal, if either party takes one, adds another twelve to eighteen months in the Colorado Court of Appeals, and another six to twelve if the Colorado Supreme Court grants certiorari. Many defect cases that go to verdict do not appeal — both sides have an incentive to take a known outcome and move on — but cases with high verdicts or with significant legal issues at stake regularly do.

Three levers that compress the timeline

Within the framework above, three things compress the timeline meaningfully:

• Engage the forensic expert before the lawyer. Pre-existing forensic work shortens phase 0 by 30 to 60 days and gives the lawyer enough to prepare the notice of claim immediately.

• Treat CDARA's notice-of-claim process as a settlement opportunity, not a checkbox. Cases that resolve here resolve fast. Even when the builder's offer is low, an early counter-offer with credible supporting documentation sometimes produces a workable number.

• Push for mediation early. Mediating once the experts have completed their preliminary work — rather than waiting for the end of fact discovery — moves the resolution conversation forward by three to six months and frequently produces settlement.

A homeowner who understands that the case clock starts at month minus-two (investigation), runs through month four (notice of claim), enters litigation at month six, and reaches a meaningful resolution point at month eighteen has a realistic mental model. The homeowner who expects "a few months" is the homeowner who is frustrated at month four and exhausted at month twelve. Both will reach the same outcome. Only one will be at peace with it.
