There's code, and then there's good practice. One receptacle per bay is AWFUL to live with. Do the homeowners a favor and give them a 120V receptacle every 6' or so the whole way around the garage. You can never have too many receptacles!
Better still, also put in a 240V 30A in every space for the inevitable car chargers.
And do it using 3/4" EMT so that all of the bases are covered, right? That's what I always try to do if budgets will permit. You never know what tomorrow's garage will need, even in a residence.
