Owner of building next door will not move his dumpster from my lot

[Atul Mohlajee]

I own a 6 unit building with parking in the back.  Dumpster of next door building has been partially encroaching a few feet into my lot for a few years.  I never paid attention until a tenant called me and said to have it removed because her son is buying a car so they need to park additional car behind her car.  Two tandem spots are hers.  I told the new owner of next door building to move his dumpster to his lot.  He was very insulting saying that he was trying to be a good neighbor and why does he suddenly has to move it.  He goes on about my tenants walk through his lot and he will collect evidence and sue me for my tenants tresspassing.  I told him to do that if he like but I will claim the spot.  I has plat of survey that shows my lot.  Also, dumpster is behind my tenant's car and clearly in my lot at least a few feet.  He told me to call recycling company which I will.  I will also call the Village.  I am thinking of legal action if all this fails.  Any ideas, please tell.  This forum is a godsend for me and is always great ideas.

Simply call the company who owns the dumpster and tell them that is on your property and when they do the next garbage pick up to make sure the dumpster is placed solely on the other person's property.  Then as Scott suggested, add some precast parking curbs to 'remind' the dumpster people not to put the bin in the parking spot.
