Thе appellant/plaintiff, Lisa Determan, discovered significant structural problems in the home she had purchased from the appellees/defendants, James and Diane Johnson. Determan filed a negligence action against the defendants to recover her costs of reрair, but the trial court dismissed her claims on the basis that the defendants owed no duty to the plaintiff. The court of appeals affirmed, holding that the plaintiffs damages were not recoverable under tort law. This court granted further review and we now affirm.
I. Background Facts and Proceedings.
In 1990, the defendants decided to build a home fоr themselves. They did not have any house plans; they simply took pictures from a magazine to the local lumberyard and asked that plans be prepared. These plans were then submitted to the city for a building permit. Defendant James Johnson, a farmer and used-car dealer, listed himself as the contractor on the application for the permit. The defendants hired a local carpenter, however, to do the actual construction. When the house was completed, the defendants and their children moved in.
In 1992, the defendants decided to sell their home аnd listed it for sale at a price of $190,000. The plaintiff and her then-husband, Jeffrey Determan, were interested in purchasing the home but had concerns about the quality of the workmanship. After receiving some reassurances from their real estate agent,, the Deter-mans bought the house for $120,000. The рurchase agreement contained the following language:
BUYERS acknowledge that they have made a satisfactory inspection of the property and are purchasing the property in its existing condition.
The BROKER, its agents, employees, and associates make no representations or warranties as to the physical or mechanical condition of the property, size, value, future value or income potential.
In 1997, after the Determans’ divorce, the plaintiff discovered a sag in the roof of the house. Further investigation, which included consultations with a local home-builder, an architect, and a structural engineer, revealed serious structural problems in the home. Specifically, the beam system supporting the roof was inadequate and did not comply with the applicable building code. In addition, a vapor barrier had nоt been properly installed, resulting *261 in significant moisture problems. The plaintiffs consultants indicated that the roof could be in danger of collapsing.
The plaintiff then filed this action against the defendants seeking recovery under several different negligence theories. 1 She sought to recоver “repair costs, loss of use, inconvenience, emotional distress, and mental pain and suffering.” The case proceeded to trial. At the close of the evidence, the defendants moved for a directed verdict on several grounds, including that they owed no duty to the plaintiff and that her recovery was limited to contract remedies. With one exception, the district court granted the defendants’ motion on all of the plaintiffs claims, holding the defendants owed no duty to the plaintiff. The only claim remaining was the plaintiffs assertion that the defendants had fraudulently failed to disclose that a substantial portion of the wastewater treatment system extended beyond the property line. This claim was submitted to the jury, which returned a verdict in favor of the plaintiff, awarding damages in the amount of $8800. Judgment was entered on the jury’s verdict, and neither party has challenged this judgment on appeal.
The plaintiff appealed the trial court’s ruling on the defendants’ motion for directed verdict, claiming there was sufficient evidence to establish that the defendants owed her a duty. We transferred the appeal to the Iowa Court of Appeals, which affirmed the district court on the basis that the plaintiff had no tort remedy for her damages.
See Moyer v. City of Des Moines,
II. Scope of Review.
Our standard of review for the grant of a motion for directed verdict is well established:
We review the trial court’s decision to direct a verdict for the correction of errors of law. A defendant’s motion for directed verdict should be denied if there is substantial evidence to support the plaintiffs claim. “Evidence is substantial when a reasonable mind would accept it as adequate to reach a conclusion.”
Hasselman v. Hasselman,
III. Governing Law.
This court has on several occasions in the past considered the compensability of economic loss damages in tort. It is helpful to briefly review this line of cases in deciding the appropriаte outcome here.
We first addressed this issue in
Nebraska Innkeepers, Inc. v. Pittsburgh-Des Moines Corp.,
In a subsequent decision, we extended this rule to bar claims basеd on strict liability in tort where a product sold by the
*262
defendant to the plaintiff failed to perform as it was expected, but caused no physical injury to person or property.
Nelson v. Todd’s Ltd.,
We agree that the line to be drawn is one between tort and contract rather than between physicаl harm and economic loss.... When, as here, the loss relates to a consumer or user’s disappointed expectations due to deterioration, internal breakdown or non-accidental cause, the remedy lies in contract.
Tort theory, on the other hand, is generally appropriate when the harm is a sudden or dangerous occurrence, frequently involving some violence or collision with external objects, resulting from a genuine hazard in the nature of the product defect.
Id. at 125 (citation omitted). In deciding whether a particular claim is cognizablе in tort or contract, we quoted with approval the following analysis suggested by a federal court of appeals:
“[T]he line between tort and contract must be drawn by analyzing interrelated factors such as the nature of the defect, the type of risk, and the manner in which the injury arosе. These factors bear directly on whether the safety-insurance policy of tort law or the expectation-bargain protection policy of warranty law is most applicable to a particular claim.”
Id.
at 124-25 (quoting
Pennsylvania Glass Sand Corp. v. Caterpillar Tractor Co.,
The distinction drawn in
Nelson
between tort claims and contract claims based on a defective product is illustrated by two of our cases in which we have applied the legal principles set forth in
Nelson,
but have reached differing results.
Compare Tomka v. Hoechst Celanese Corp.,
In
Tomka,
the plaintiff operated a custom feeding operation.
In contrast, in
American Fire,
we permitted a tort recovery when the defect in the product — а truck — caused a fire that damaged the truck and its contents.
With this framework to guide our analysis, we now consider the facts of the case before us.
IV. Application of Law to Facts.
In the present case the evidence introduced at trial showed that the house purchased by the plaintiff from the defendants suffered from significant structural defects. Spеcifically, the structural support for the roof was woefully inadequate and the moisture barrier in the walls had been improperly installed. These defects manifested themselves in the form of sagging areas in the roof, cracks in the walls, and moisture spots on the walls and ceilings. Although the plaintiffs experts testified that the roof could eventually collapse, that occurrence had not yet materialized at the time of trial. Thus, the plaintiffs damages consist of the expenses she has and will incur to repair the defects in the home’s construction.
In deciding the proper remedy for the plaintiffs loss, we look to “ ‘the nature of the defect, the type of risk, and the manner in which the injury arose.’ ”
Nelson,
The plaintiff argues that because the house presents a danger to its occupants, a tort recovery should be allowed. But this argument ignores the fact that our decision rests on a consideration of not only the type of risk, but also the nature of the defect, the manner in which the injury occurred, and the specific injury for which compensatiоn is sought. Based on a weighing of all of these factors, we conclude that the plaintiffs claim is based on her unfulfilled expectations with respect to the quality of the home she purchased. Accordingly, her remedy lies in contract law, not tort law.
See American Fire,
This conclusion is consistent with our analysis of a strikingly similar issue considered in a different context in
Flom v. Stahly.
In
Flom,
the plaintiffs had purchased a home from the defendants, which had been constructed in large part by one of the defendants, a medical doctor by profession.
The pertinent issue on appeal was whether the plaintiffs’ recovery should be reduced by their own fault under our comparative fault statute, Iowa Code chapter 668 (1991). Id. at 140. We held that the comparative fault statute was limited to liability in tort. Id. at 141. Therefore, we examined whether the plaintiffs’ claim was *264 contractual in nature or cognizable in tort. Id. We held that it was contractual in nature, and therefore not subject to the сomparative fault statute, because “[t]he harm alleged was to the object of the contract (the house) and not to [the plaintiffs’] persons or other property.” Id.
Similarly, here, any harm caused by the defects in the house was to the house itself, and not to any persons or оther property. In addition, as noted above, there has been no “sudden or accidental occurrence”; rather the harm for which the plaintiff seeks to recover “relates to [the plaintiffs] disappointed expectations due to deterioration, internal breakdоwn or non-accidental cause.”
Nelson,
V. Conclusion and Disposition..
Viewing the facts in a light most favorable to the plaintiff, we conclude that the evidence is not sufficient to support a recovery under the tort theоries upon which she relies. Therefore, the trial court correctly granted a directed verdict for the defendants on these claims.
DECISION OF COURT OF APPEALS AND JUDGMENT OF DISTRICT COURT AFFIRMED.
Notes
. The plaintiff’s petition also included a breach-of-implied-warranty claim, but it was dismissed on the defendants’ motion for directed verdict. The dismissal of the wаrranty claim is not challenged on appeal. In addition, the plaintiff claimed that the defendants had fraudulently concealed the home's structural problems from her. The trial court also dismissed this claim, and this dismissal was affirmed by the court of appeals. The plaintiff has not asked this cоurt to review that ruling.
. In deciding whether a plaintiff may rely on a theory of strict liability, the Superior Court of Pennsylvania has rejected the test set out in
Pennsylvania Glass
in favor of a stricter test that focuses solely on whether "the damage alleged is to the product itself, whether or not the defect posed a risk of other damage or injury or manifested itself in a sudden or calamitous occurrence.”
