Fireblocking should be installed in these locations:
1. Concealed spaces of stud walls and partitions, including furred spaces at ceilings and floor levels.
2. Concealed spaces between stair stringers at the top and bottom of the run.
3. Openings around vents, pipes, ducts, chimneys, and fireplaces at ceiling and floor levels.
4. Interconnections between concealed vertical stud wall or partition spaces and concealed spaces created by an assembly of floor joists. With respect to concealed spaces created by an assembly of floor joists, fireblocking should be provided for the full depth of the joists at the ends and over supports.
5. Attic side with 5/8" fireblock drywall.

That is what my City asks… At one time insulation could be used for firestop they changed that to solid material. I would just state you recommend installing 5/8 for safety…again Home Inspections are not code inspections.
