I would approach it in an understanding manner. I would tell him that you don't like people parking in front of your house either but you have to park where you can and that the streets are public property. Appreciate that it most likely annoys him but that you need a place to park too and if you had your way, you wouldn't park in front of his house either. If hes cool and understanding, problem avoided. If hes a fat redneck hillbilly asshole, id resort to urban warfare....
