What is the name of your state (only U.S. law)? Pennsylvania. What are my rights when it comes to other people parking in our parking spaces? Background: I own a house that has two parking spaces behind it and I have it posted no parking and no trespassing however at times I'm come home and people are park in them. I have called the police on occasions and the situation still happens. As a homeowner what are my rights and what can I do to stop this from happening. Any help and advice would be appreciated. Thank you for your time in this matter.
