Detached garage being built in Suburb of Detroit, MI

Contractor claims a dispute I am having with him is because "It is Code."
But somehow contractor's claim of "Code" is so un-reasonable for a
detached garage, it makes me think any similar actual rule would be for an
attached garage.

Cannot seem to find anything on internet for local building code (county
or city). So, How do I find out if contractor is bull***ting me or if
there is really a building code requirement.

No, I an not sure I do trust him on this issue.

You got more than one estimate right? Check with the others. Call your
city hall as they will have the info on what is 'code'.
