My question involves real estate located in the State of: California
We have lived in this house for over 15 years. New tenants have moved into the house across the street about 5 months ago. They have repeatedly parked behind our driveway blocking us in, verbally harassed us when we walk outside, threatened my dog, and play music loudly (to the point we can hear it over the tv and late at night). This has been an issue for the entire time they have lived there. We started by asking them to please stop. It escalated to almost daily harassment. We have called the police to file reports, but they say they cannot do anything. We have talked to the landlord, but have received no help. Is there something else we can do?
