“The essential elements to pleading a claim for trespass under California law are: 1. The plaintiff owned, leased, occupied, or otherwise controlled the subject property; 2. The defendant intentionally, recklessly, or negligently entered the plaintiff’s property; 3. The plaintiff did not give permission for the entry; 4. The plaintiff was actually harmed by the unauthorized entry on to his property; and 5. The defendant’s entry or conduct was a substantial factor in causing the plaintiff harm.”
