My car parked at my residence was made dirty by some neighbouring building construction. Can I get compensated in some way (e.g., paying for car wash)? I live in California, USA.
The tort of trespass addresses this situation.
In California, the plaintiff in a trespass suit must prove five things:
Plaintiff occupied the property;
Defendant negligently entered plaintiff's property (this can include an entry by the defendant, or by tangible objects that the defendant caused to enter the property, Newhall Land & Farming Co. v. Superior Court 19 Cal.App.4th 334, 345 (1993));
Plaintiff did not authrize that entry;
Plaintiff was harmed; and
Defendant's entry caused that harm.
Obviously, the time and expense associated with pursuing this lawsuit would quickly outstrip the value of any damages likely to be recovered. But a person who just really wanted to stick it to the construction company should have a viable case.
