Insulating garage wall

I have some leftover kraft-faced insulation that I was going to use to insulate the wall between my garage and interior. Access to insulate the wall is from the garage side. I believe best practices say that the kraft face should be on the interior side of the wall, but it would be easier to keep the barrier on the garage side. Does it really matter in a mild northern-california climate? Any suggestions are appreciated.

It matters: Vapor retarder toward living side

Vapor retarders on insulation are there to control the movement of gaseous water thru the wall and to help alleviate condensation problems within walls.

Since even in mild climates, condensation can occur with slight changes of temperature depending upon the relative humidity, a vapor retarder is still necessary toward the living space side of the wall structure.

So the short answer is , YES, you need the vapor retarder on the living space side of the wall.
