Order unanimously reversed on the law with costs, motion denied and complaint reinstated. Memorandum: Supreme Court erred in summarily granting defendants' motion for summary judgment dismissing the complaint in this negligence action. Denise Hightower (plaintiff) sustained injuries when she slipped and fell on an oily spot in the parking lot of a nursing home owned and operated by defendants. In support of their motion, defendants submitted proof in admissible form to show that they did not have actual or constructive notice of the oil spill (see, Eddy v. Tops Friendly Mkts., 91 A.D.2d 1203, affd 59 N.Y.2d 692).
In our view, however, the evidence submitted by plaintiffs in opposition to defendants' motion raised triable issues of fact whether defendants had constructive notice of the oil spill. "To constitute constructive notice, a defect must be visible and apparent and it must exist for a sufficient length of time prior to the accident to permit defendant's employees to discover and remedy it" (Gordon v. American Museum of Natural History, 67 N.Y.2d 836, 837). At her deposition, plaintiff testified that she slipped on some black, dirty and sticky oil on the parking lot. She further testified that the oil appeared to be "old oil". Plaintiffs also submitted an affidavit of an expert witness asserting that oil that leaks onto average blacktop and remains there for several days appears old, sticky, coagulated and embedded, and that the process of dissolving the sealant takes on average a minimum of four days to a week. Whether the oily spot that allegedly caused plaintiff to slip and fall existed for a sufficient length of time to permit defendants' employees to remedy the defect, and whether such condition was visible and apparent, are issues for the trier of fact (see, Schneider v Ardsley Tenants Corp., 191 A.D.2d 265).
