I have a closet in the basement. One of the walls has foam between the closet wall and the concrete wall. Do I have to put dry wall there for fire code?

yes. all walls and ceilings need drywall to meet fire code. some walls may even require thicker drywall depending on the occupancy class of the rooms being separated. you also need make sure that all the walls are draft stopped at the plate line. I say this cause i notice the copper pipes on the ceiling that you will probably be framing around it or dropping the ceiling so you need to make sure the ceiling cavities are separated from the wall cavities.

Local Code may also require a fire-stop 2x4 (PT or vapor barrier on concrete there) BETWEEN the foam board, every 10' across the wall vertically- in the whole basement. Also an "egress" window before finishing, maybe.

isn't a closet door adequate to meet the requirement? Its not like the foam is exposed to the open basement.. its inside the closet..

Short answer is"no"

It's probably not a rated door and doors that get opened don't always get closed.

Drywall the closet and mud tape with at least two coats. Like a garage.

okay so how about this then: we have seen hundreds of examples of people redoing their basements. The premier protocol is to glue XPS to the foundation and then build a wall in front of it. almost every basement has a water line and perhaps gas line entering the house and USUALLY a closet door is placed in front of those service areas for access. (you cant just put a wall in front of your water/gas meter). So they have the XPS on the foundation BEHIND the gas/water meter with a door to get access to the meter.

How are those people putting sheetrock over the XPS then? Are you supposed to frame an entire "mini closet" with rock on 3 sides for the meter access? I liked the idea of being able to peer down the entire run of the foundation wall from that access door.

If all the draft stop and fire stop is done correctly, you would only be able to see 10' down and then there would be a draft/fire stop. and yes it almost never is done correctly.
