This might be standard but it doesn't really make it right. I wouldn't call the police though, they probably can't and almost certainly won't help with this situation.

If you really can't live with it then you want to write a series of letters to whatever municipal authority controls the street signs or issues parking tickets for illegal parking on that street. Once you've got the name of the correct person to write letters to and you've written three or four well worded (and perfectly nice) notes to him or her the chances are something will change. Be sure to start cc'ing other people in on the letters, say the persons boss, by the third or fourth attempt.
