Pop:

here is the IRC code reference and it doesn't cover height

old CABO code required 4"

check with your permit office as each locale can be different, even if they use the IRC they can modify it

The IRC states:

R309.1 Opening protection.
Openings from a private garage
directly into a room used for sleeping purposes shall not be permitted.
Other openings between the garage and residence shall
be equipped with solid wood doors not less than 13/8 inches (35
mm) in thickness, solid or honeycomb core steel doors not less
than 13/8 inches (35 mm) thick, or 20-minute fire-rated doors.
