A.R.S. 12-552: Arizona's 8-Year Deadline to Sue Over Construction Defects

There is a final cutoff on suing over a construction defect in Arizona, and most homeowners do not know about it until it is too late. A.R.S. 12-552 says you generally cannot bring a defect claim more than eight years after the home was substantially complete, no matter how recently you found the problem. This is a statute of repose, which is different from a statute of limitations, and the difference is what makes it so unforgiving. This page explains the deadline, when the clock starts, and the narrow one-year extension that turns it into a nine-year limit.

What this statute does

A statute of repose sets an absolute end date. It is measured from a fixed event, here the completion of the building, not from when you found the harm. That is the key contrast with a statute of limitations. A limitations clock usually starts when you knew or should have known about an injury. Under 12-552, once eight years pass from substantial completion, the door closes. It closes even on a defect you could not have seen earlier.

Notwithstanding any other statute, no action or arbitration based in contract may be instituted or maintained against a person who develops or develops and sells real property, or performs or furnishes the design, specifications, surveying, planning, supervision, testing, construction or observation of construction of an improvement to real property more than eight years after substantial completion of the improvement.

The statute applies to the people who build and design: developers, builders, architects, engineers, surveyors, and similar parties. It covers claims based in contract, which is the usual footing for a defect dispute between a homeowner and the builder.

When the clock starts and the 9-year stretch

The eight years run from substantial completion, which the statute pins to the earliest of three events: the home is first used by the owner or occupant, it first becomes available for use under the contract, or it passes final government inspection. For a typical new custom home, that is usually the certificate of occupancy or the day you move in, whichever comes first.

One narrow extension exists. If the injury from a defect first appears during the eighth year after substantial completion, you get one additional year from that discovery to file, but the claim can never be brought more than nine years after completion. That is the absolute ceiling. There is no further tolling for a latent defect found in year ten.

What it means for your home build

For example, say Jematell finishes your custom home in Fountain Hills and you take occupancy in March 2026. Under 12-552 your outer window to sue over a construction defect generally closes in March 2034. If a foundation crack tied to expansive soil first surfaces in, say, late 2033 (year eight), the nine-year rule gives you until March 2035 at the latest. A crack that first appears in 2036 is outside the statute, and the claim is barred even though it was genuinely hidden.

The practical lesson is to act on warning signs early. Document any defect the moment you notice it, and do not let years drift by assuming a long deadline. This repose period runs in the background of every other defect remedy, including the implied warranty of workmanship and habitability that protects new-home buyers. The warranty gives you the right to sue; 12-552 sets the latest date you can use it.

How this connects to other rules

This deadline works alongside, not instead of, Arizona's general limitation periods. A breach-of-contract claim also carries its own statute of limitations that starts at discovery, and whichever bar hits first controls.

Because the eight- and nine-year math turns on the exact completion date and when a defect first appeared, confirm both dates with an Arizona construction attorney before assuming a claim is alive or dead.
