I live in a row of townhouses that has a shared parking lot in the back. My neighbors on both sides use their garage space as living space and often will park directly in front of their home (parallel to where the garage would be). I, however, use my garage to park my car and have difficulty maneuvering into and out of the space due to my neighbors parking their cars too close. I have lines painted on the ground to designated how much room they have to park before they block my garage, but despite repeated requests they regularly park too close and I either have to do a 9 point maneuver to get into/out of the garage, or ring their doorbell and ask them to move their vehicle.

How do I find out if it is illegal for them to park there? There are spaces against the fence for everyone, but because they have too many vehicles they can't fit them all in (or can't be bothered to do so). Also, there is a fire hydrant near one of the townhouse garages further down; can I call the fire department to say that these cars are blocking access?
