Plaintiffs, ORDER

v.

Costco Wholesale Corporation, et al.,

Defendants. Pending before the Court is a Report and Recommendation (“R&R”) (Doc. 52) issued by United States Magistrate Judge Michael A. Ambri, which recommends granting in part Defendant Costco’s Motion for Summary Judgement (Doc. 37) and denying Plaintiffs’ Cross-Motion for Summary Judgment (Doc. 41). Defendant objects to the R&R. Doc. 53. The Court will overrule the objections and adopt the R&R in full. I. Background On November 12, 2021, Plaintiff Rita Tapia slipped and fell while exiting a Costco warehouse store in Tucson, Arizona. The Complaint alleges Tapia slipped on water near an ice machine. Plaintiff alleges the fall caused a lower leg fracture and shoulder injury, and that she underwent a total knee arthroplasty (“knee surgery”) as a result. Defendant alleges Plaintiff fell because she slipped on ice that a customer had dropped only 19 seconds earlier. Defendant also disputes that the fall caused the knee surgery because Plaintiff’s orthopedic surgeon had recommended and scheduled the exact same procedure 10 months before the fall. Plaintiff provided an affidavit stating she had decided to postpone the surgery indefinitely, but the fall aggravated her condition and ultimately forced her to have the knee surgery. On October 22, 2024, Defendant filed a Motion for Summary Judgment (Doc. 37). On December 5, 2024, Plaintiff filed a Response and Cross-Motion for Summary Judgment. Doc. 41. On April 9, 2025, Judge Ambri issued his R&R. Doc. 52. II. Legal Standards a. R&R Findings and Recommendations The Court “may accept, reject, or modify, in whole or in part, the findings or recommendations made by the magistrate judge.” 28 U.S.C. § 636(b)(1). The Court “must review the magistrate judge’s findings and recommendations de novo if objection is made, but not otherwise.” United States v. Reyna-Tapia, 328 F.3d 1114, 1121 (9th Cir. 2003) (en banc). The Court is not required to conduct “any review at all . . . of any issue that is not the subject of an objection.” Thomas v. Arn, 474 U.S. 140, 149 (1985). The party seeking de novo review must provide “specific written objections to the proposed findings and recommendations” in the R&R. Fed. R. Civ. P. 72(b)(2) (emphasis added). b. Summary Judgment Summary judgment is appropriate under Federal Rule of Civil Procedure 56(a) where the moving party demonstrates the absence of a material fact dispute and entitlement to judgment as a matter of law. See Fed. R. Civ. P. 56(c); Celotex Corp. v. Catrett, 477 U.S. 317, 322 (1986). When making a summary judgment determination, the Court must draw all inferences from the underlying facts in the non-moving party’s favor. Id. at 587. III. Analysis Defendant makes three objections to the R&R: (1) that International Building Code (“IBC”) § 1003.4 is not specific enough to support a negligence per se claim; (2) there is insufficient evidence Defendant violated IBC § 1003.4; and (3) Plaintiff’s knee surgery damages rely on a “sham affidavit.” Defendant seeks summary judgment on Plaintiff’s negligence per se claim and Plaintiff’s knee surgery damages. The Court reviews each objection de novo. a. IBC § 1003.4 is Specific Enough to Support a Negligence Per Se Claim. “Negligence per se is limited to situations involving a violation of a specific legal requirement, not a general standard of care.” Ibarra v. Gastelum, 471 P.3d 1028, 1030 (Ariz. Ct. App. 2020). If a statute does not “proscribe certain or specific acts,” but instead “defines only a general standard of care,” negligence per se cannot be the basis for a claim. Id. at 1030–31. Plaintiff alleges Defendant violated two separate provisions: International Property Maintenance Code (“IPMC”) § 305.4 and IBC § 1003.4.1 These two provisions happen to illustrate the contrast between a general versus specific standard of care. Under IPCM § 305.4, “[e]very . . . walkway surface . . . shall be maintained in sound condition and good repair.” Id. “Sound condition and good repair” is a general standard and thus cannot support a negligence per se claim. In contrast, IBC § 1003.4 provides: “Walking surfaces of the means of egress shall have a slip-resistant surface and be securely attached.”2 Id. Contrary to Defendant’s objection, § 1003.4 need not define “slip-resistant” to meet the specificity required to support a negligence per se claim. See Doc. 53 at 4. Defendant’s contention that the building code needs to prescribe a minimum co-efficient of friction or require an “exact type of flooring” to be specific enough is inconsistent with Arizona law. The term “slip-resistant” can be given its ordinary, common meaning. See Johnson v. Tucson Ests., Inc., 683 P.2d 330, 334 (Ariz. Ct. App. 1984) (jury permitted to “give the ordinary, common meaning to the word nonslip without further definition in the
