Help! Making dinner for friend with Celiac!

I am trying to make us a gluten free pasta dinner with a gluten free garlic bread for him. The pasta is gonna be completely gluten free, nothing to worry about there. My concern is with the garlic bread. I have special bread just for him because I want him to be able to enjoy the same things as us. So I have both a gluten free bread and a regular bread that i'm making sure to put together separately was completely clean countertops and utensils every time. What I want to know is if I I'm baking the garlic bread... Do I have to bake them at separate times or can I bake them in the same oven? The dinner is tonight.
