I only mention this because something similar happened to me and my shop.
Excuse me if I've mentioned this before

An inspector rolled into the shop and told me we had an illegal roof at the back. There's a patio at the back of the shop and the previous occupants put a plastic roof on it and I now use the room for storage.
Anyway, Mr Jobsworth told me to take it down. I said no. He said you'll be hearing from us.
Fortunately another inspector at the muni gets her hair done next door and the owner of the hairdressers is a client of my wife who is an accountant.
She had a quiet word with the lady inspector and the problem went away.
I might add that Mr Myjob-is-more-important-than-yours, got a serious bollocking as he didn't ask for the Libro de Actas (AKA The Holy Bible).
Which really means he was simply after money.
Nobody has bothered us since, but you never know do you?
