There is already impervious coverage on the ground, sloped that way. This shed does nothing to change that, and it's not attached to the ground. If you really want to get away with this from a code standpoint, put wheels on it.

Could maybe slant it parallel to the house? Towards the photographer in these photos - not directly at either the house or the property line.

Well then he’d get wet going into the shed. He might not mind but his equipment will. Toward the fence or back would be better.

I also wonder from a water damage standpoint if he vented this or he’s counting on the door for ventilation. That won’t always be open.

Ah good point :)
