MEMORANDUM ***

“Where [a] dangerous condition is brought about by ... third persons ... or by other causes which are not due to the negligence of the owner, or his employees, then to impose liability the owner must have either actual or constructive knowledge of the dangerous condition[.]” Hatfield v. Levy Bros., 18 Cal.2d 798, 117 P.2d 841, 845 (1941).

Hall alleges that Regal had constructive knowledge of the spill because: (1) Regal’s ushers aren’t provided “carpet cleaner, cleaning solutions, or scrapers” to clean spills; (2) no one addressed the spill for at least 30 minutes after Hall reported it; and (3) Hall’s expert inspected the theater three years later and observed “[s]lippery and sticky spots” on the carpet. These allegations may indicate that Regal didn’t properly clean up spills after Hall slipped, but they have no bearing on Regal’s constructive knowledge of the dangerous condition beforehand. “In the absence of actual or constructive knowledge of the dangerous condition, the own-' er is not liable.” Moore v. Wal-Mart Stores, Inc., 111 Cal.App.4th 472, 3 Cal.Rptr.3d 813, 816 (2003).

AFFIRMED.
