Presumably that qualifies as vandalism unless you own 10 feet of property in a ring around his house, which is an uncommon situation. Depending on the wording it might also qualify as attempted kidnapping or unlawful imprisonment or something along those lines.
I just looked up the vandalism laws in my state and I didn't see the sentence "building a most around your neighbor's house is illegal" anywhere, so I think I'm in the clear
I mean, if you owned that 10' ring of property, sure. Presumably digging out 10' of public Street or 10' of his yard against his will would fall under vandalism though.
I feel like you haven't studied the pivotal case law Timberwolves v. Air Bud which clearly sets the precedent that any omission that isn't clearly and explicitly stated is inherently considered condoned by law.
