Why does a townhouse which is 4-story require an NFPA 13R system?
The IRC is specifically geared toward one-and two-family dwellings up to 3 stories, but the IBC allows 13D systems in R-3, R-4 condition 1 and townhouses (903.3.1.3).
Is there another prevailing code reference that overrules this allowance?

I'm not sure I understand your question completely.

In addition to James comment, the IRC scope is limited to 3 stories in height.
