When it comes to this type of enforcement, the complaints usually come from business interests looking to the government to throttle any form of competition.
Not always.
I'm on a lot, 200x100 ft, and some of my neighbours could use a good *$^%## kicking.
One of my neighbours is in construction, and steals everything he can, for "eventual" use at home. Until that appointed time, all the materials sit in his yard. His wife runs a wood work refinishing business, and so aside from the mess next door, I can enjoy the wonderful music of saws all day. Including Sundays and holidays.
Another one sold his car repair place in the city, and now runs a garage out of his home.

If someone wants to run a business, which this nice old man wasn't doing,......more power to them.
Just don't do it 15 feet from my back yard when only residences are allowed.
Flame away.
No flames here, people who disturb neighbours deserve a whupping, but unfortunately most bylaw officers seem to go after those who are harmless.
