Shed setback variance - question

Hey All!

I'd like to build a shed out the side of my house, between house and shared fence with neighbor.

My neighbor is cool with me building almost up to the property line, but it would break setback code. Size is under the max sqft rule.

Has anyone received a variance, getting within 6in of the property line?

Part of me is thinking of just building and seeing what happens. Lots of people in the neighborhood seem to have sheds against property line, neighborhood was built in the 50s.
