Why can't Code do anything?

This is what's happening in my neighborhood. It seems evident that this owner is conducting a commercial business out of his house. He parks these vans all over even on city property (sidewalk and swale).

436 Wright Drive

This house is across the street from the one at 436 Wright Drive and this huge commercial monstrosity is parked there all of the time.

This used to be a wonderful street. Now our neighborhood is being trashed, big time and even after numerous complaints, nothing changes. Why aren't the neighbors raising holy hell?
