I'm pretty sure it should be 5/8 fire rated that is two layers thick. I think it also goes from the roof decking to the slab with no protrusions unless firecaulked. And by two layers it could be one sheet thick per side. But please verify.

A town home that you purchased should have 2 hour separation. 4 layers of 5/8. 2 on your side and 2 on your neighbor's side. Look at a wall that tee's of the party wall and see if there is a gap for the Sheetrock to pass behind the tee. Measure the gap, (if any) and it should tell you how it was constructed before.

Need to get an inspector on the horn. This isn't something you leave up to an internet forum.

to meet code for a common wall, you need to use 5/8" for fire proofing and you are only obligated to make sure "your side" of the wall meets code. LINK
you are also required by code to have this type of insulation in the wall (on your side only) but if you want a quiet house, it is highly recommended that you spend the money to do a double layer of sound deadening insulation, one layer on your wall and one layer on the neighbors wall, with an air space between them to prevent sound transfer, you wont even know you have someone living on the other side of that wall.

Two layers of 5/8 fire rock drywall. Fire caulk it too.

Typically a common wall has a 2 hour wall between.
A lot of 2 hour walls are 2 layers of 1" in a metal track. There should be a stud wall framed about 1" away from it. If it got flooded that type of separation is not an easy fix.
Cut a hole, the only way you would truly know, fix/ replace what's there.
