What are the laws on private property ?

My neighbor parks in between our buildings because there is a little driveway. I rent where I live and where she parks is not her property because she “rents” as well even though she really doesn’t pay rent or property taxes which is illegal. . . But if I park behind her and she is blocked, is she allowed to call the cops and have me move my car even though it is not her property and the landlord who owns the property was not there to say anything about the parking ? Is that legal ?
