What's in writing is subject to interpretation.
My guy had three 'I really like to see' things that weren't code. I looked at him with a blank stare each time until I realized he was not going to move past it.
We could have argued and I would have lost. Maybe I would have won an appeal down the road, and been awarded my $600 permit extension back. Also maybe not, and definitely no time soon.
For example, my code clearly stated I needed a door alarm, which I had. The inspector said because I had a screen door, it would need it's own alarm so that we could use it in the summertime as the primary door. Not one word of that was mentioned in the code, but it's how he interpretated it. Another inspector may not have considered the screen door an acceptable barrier to need its own alarm. It's all in who you're talking to, and what mood they're in that day.
