Dealing with Bad Neighbor?

My parents’ basement has been flooding when it rains. The source of the water seems to be a wall shared with a vacant house that was recently purchased by an investor. There is no plumbing on my parent’s side of the wall, but the neighbor’s basement sewer pipe runs along the wall.

My parents have called the owner to try to confirm the source of the flooding and to ask that he make the necessary repairs. They have received no response.

How should my parents proceed? Will the city allow a plumber to access the property by forcing the door? Any other ideas?
