We granted leave in this case to determine whether a defense of proper supervision may bar a true building defect claim under the public building exception to governmental immunity. Finding it does not, we reverse the decision of the Court of Appeals [85]*85and remand this case to the trial court for further proceedings consistent with this opinion.1

On March 11, 1983, plaintiffs’ decedent was involuntarily admitted to Ypsilanti Regional Psychiatric Hospital. There, decedent was diagnosed with reactive depression, thought disorders, and suicidal preoccupation. The decedent was immediately placed on one-to-one suicidal precautions. Six days later, he was taken off one-to-one watch and was placed on general suicidal precautions.2 The following day, while still on general precautions, the decedent hanged himself by attaching a cloth belt to an overhead dividing bar inside a toilet stall in the facility’s restroom.
For the past decade, this case has weaved its way through the judicial system. Separate lawsuits were originally filed in the Court of Claims against the Department of Mental Health and in the Washtenaw Circuit Court against Dr. Genoves-Andrews.3 On September 6, 1984, the Department of Mental Health was [86]*86granted summary judgment pursuant to GCR 1963, 117.2(1), now MCR 2.116(C)(8).4 Dr. GenovesAndrews was granted summary judgment pursuant to GCR 1963, 117.2(1) on June 29, 1984.5 On appeal, the grant of summary judgment in favor of Dr. GenovesAndrews was reversed.6 In addition, the grant of summary judgment in favor of the Department of Mental Health on the defective public building claim was also reversed.7 On all other counts, summary judgment was affirmed.
An application for leave to appeal to this Court was filed by defendants. In lieu of granting leave, we remanded the case to the Court of Appeals for reconsideration in light of Canon v Thumudo, 430 Mich 326; 422 NW2d 688 (1988), Reardon v Dep’t of Mental Health, 430 Mich 398; 424 NW2d 248 (1988), and Smith v Dep’t of Public Health, 428 Mich 540; 410 NW2d 749 (1987).8 On remand, the Court of Appeals modified its earlier opinion regarding the grant of summary judgment in favor of the Department of Mental Health. Specifically, the Court upheld the grant of summary judgment on that portion of plain[87]*87tiffs’ claim that related to the defendant’s failure to design the restroom in a maimer that would allow proper observation and supervision of patients.9 The Court found, however, that plaintiffs’ allegation that the restroom design was dangerous or defective in light of the suicidal tendencies of its users was sufficient to withstand summary judgment. In all other respects, the Court upheld its previous ruling.
On remand from the Court of Appeals, the defendants moved for summary disposition pursuant to MCR 2.116(C)(10). That motion was denied on August 6, 1992. On defendants’ motion for reconsideration, the trial court reversed itself and granted summary disposition for both defendants. After remand, the Court of Appeals affirmed,10 and we granted leave to appeal.11 Plaintiffs do not appeal the order granting Dr. [88]*88Genoves-Axidrews’ summary disposition. Accordingly, the only issue before this Court is whether defendant Department of Mental Health was properly granted summary disposition where it was concluded that proper supervision would have offset shortcomings in the configuration of the room.
n
The issue before us is not whether a defect in the building actually existed or whether, if a defect did exist, the defendant’s actions were the legal or factual cause of the decedent’s death. Plaintiffs contend that a defect did exist and the Court of Appeals did not revisit this question. Instead, the sole issue on appeal is whether the defense of proper supervision bars a true building defect claim. Defendant concedes that, as the common restroom for the ward, the restroom was to be used by suicidal patients. Defendant contends, however, that because the restroom was never assigned to be suicide proof, and reasonable supervision could have prevented the suicide, there was no building defect.12 The argument is as follows: where a [89]*89known suicidal patient in a psychiatric hospital uses a room that was not specifically assigned to hold actively suicidal patients without supervision, would proper supervision have prevented the suicide? If the answer is yes, the public building exception does not apply and the government entity is shielded from liability under the state immunity statute, even if a defect did exist.13 The Court of Appeals concluded that “[b]ecause the undisputed evidence indicates that proper supervision would have offset any shortcomings in the configuration of the room, summary disposition was properly granted on the building design defect claim.”14 In our view, this holding blurs the distinction between those claims that allege mere negligence and those that allege a true building defect. Accordingly, we reverse the decision of the Court of Appeals.

This Court has held that as long as a physical defect in the building itself coincided to cause the injury, the government entity may be liable under the public building exception even if negligent supervision was involved.21 In Bush v Oscoda Area Schools, 405 Mich 716; 275 NW2d 268 (1979), the majority concluded that the plaintiff stated a claim under the public building exception, despite the fact that allegations of negligent supervision also were made. There, the plaintiffs child sustained injuries when an explo[92]*92sion rocked a public school classroom. In her suit for damages, the plaintiff alleged that the injuries arose out of the defendant’s failure to supervise, coupled with a lack of safety equipment in the classroom.22 The majority held that the plaintiff had stated a claim under the public building exception to the governmental immunity statute.
Likewise, in Williamson v Dep’t of Mental Health, 176 Mich App 752, 758; 440 NW2d 97 (1989), the Court of Appeals concluded that a defect in the defendant’s building existed, despite the fact that improper supervision was also a contributing cause of the decedent’s death. The Court opined that
[w]hile it is true that cases which involve nothing more than improper or inadequate supervision do not make out a case under the building exception to governmental immunity, we disagree with defendant’s contention that this case is one involving only improper supervision. We believe that the facts of this case involve a building defect as well. [Id.]
The assertion that “proper supervision would have offset any shortcomings in the configuration of the room” was first pronounced in Reardon, supra at 417. In Reardon, a nursing student sought damages for a sexual assault she suffered while occupying a room in the defendant’s dormitory. The crux of plaintiff’s complaint was that her dormitory room was unsafe because numerous master keys were in circulation. In a companion case, Schafer v Ethridge, a mentally retarded resident of a state facility was sexually assaulted and impregnated. The substance of this complaint was that the layout of the facility created a [93]*93dangerous or defective condition in the building because it hindered staff supervision. Finding that neither case involved an injury caused by a condition of the building as used for its intended purpose, the majority concluded that the public building exception did not apply. Id. at 400.
In Reardon and Schafer, sexual assaults on a student and patient were found not to state a claim in avoidance of governmental immunity because the building, which was being used for its intended purpose, was not defective.23 Unlike Bush and Williamson, in which defects in the buildings were allegedly contributing causes of the injuries, the consolidated cases of Reardon and Schafer involved nothing more than mere negligence.24 It is in this context that the Court in Schafer declared that “proper supervision would have offset any shortcomings in the configuration of the room.” Id. at 417.
In Hickey, supra, the plaintiff contended that the improper design of the facility impeded supervision resulting in a dangerous or defective condition in the building. The plaintiff’s son committed suicide in a Michigan State University Department of Public Safety holding cell where he was held after being arrested for driving under the influence of intoxicat[94]*94ing liquor.25 None of the decedent’s personal effects were removed when he was placed in the cell. By fashioning his belt and socks into a noose, the decedent hanged himself from one of four metal brackets that attached a heating unit to the wall. The question was whether a dangerous or defective condition existed in the holding cell.26
Three arguments were advanced in support of the plaintiff’s contention that the public building exception was applicable. First, the plaintiff alleged that the holding cell’s improper design created a dangerous or defective condition because it prevented proper supervision. Next, the plaintiff alleged that the lack of state-of-the-art equipment in the cell created a dangerous or defective condition. Third, the plaintiff asserted that the heating unit and metal brackets created a dangerous or defective condition because they were improperly placed. The Court concluded that the claim against Michigan State University was barred by governmental immunity.27 Regarding the improper design allegation as a dangerous or defective condition, we rejected the plaintiff’s effort to posit the defect on a negligent supervision allegation, saying
a claim based on the inability to observe Hickey because of the structural design of the dps is an insufficient basis on [95]*95which to apply the public building exception. Before a claim under a building design defect can support invoking the immunity exception, such a design must more directly cause the injury at issue. [Id. at 424.]
With no defect in the building itself having been found, the Court explained that “more effective supervision would have overcome this alleged design defect in the holding cell.” Id.
More recently, in Jackson v Detroit, 449 Mich 420; 537 NW2d 151 (1995), the “proper supervision” language was again referenced. Finding that the plaintiff’s claim involved safety in a public building rather than the safety of a public building, we concluded that the claim did not come within the confines of the public building exception. Although it was stated that “where proper supervision would have ‘offset any shortcomings in the configuration of the room,’ the public building exception does not apply,”28 it is clear that the proper supervision language was merely another way of explaining that because the gravamen of the complaint was negligent supervision, the plaintiff had not alleged a dangerous or defective condition of the building itself.
Plaintiffs correctly acknowledge that where the essence of a tort claim is negligent supervision, a plaintiff cannot transform the claim into a building-defect claim merely because a superior building design would have improved the ability to supervise. Similarly, where the essence of a tort claim is a defective building under the public building exception, summary disposition may not be granted simply by [96]*96claiming that proper supervision would have averted the irijmy.29
Despite the oft-cited proposition that a public building may be dangerous or defective because of its improper design,30 the issue whether a design defect may actually constitute a defect in a public building sufficient to invoke the public building exception has caused this Court considerable difficulty. Nonetheless, that issue is not before this Court. In the present case, the plaintiffs have alleged that a dangerous or defective condition existed in the building itself. We hold that the plaintiffs were not required to “present evidence that more extensive supervision could not have prevented the suicide or that such supervision could not have been reasonably implemented”31 in order to defeat the defendant’s motion for summary disposition. This is not to say that a question of fact remains regarding the existence of a true building defect or that the defendant might not be entitled to judgment as a matter of law on the question whether a true building defect existed.32 We are saying, how[97]*97ever, that the defense that proper supervision would have prevented the injury does not negate the allegation of a true building defect so as to permit the conclusion that there is no question of material fact regarding the existence of a defect. Accordingly, we reverse the decision of the Court of Appeals and remand this case to the trial court for further proceedings consistent with this opinion.
