Over here in the USA, we got an annoying thing called "Code Enforcement" that most states have. Every county has a set of codes set ranging from home businesses, to things like parking your cars along the street.

Theres a section of my counties code that makes it difficult to do any major auto work.I had a code enforcement officer come around a few days after I got my car writing violations about having no tag and running what he called a "home auto repair business." As I said, its hard to do any auto work without someone complaining.
