SORRY make that nfpa 24

getting old

RE: nfpa 20 scholars

I don't know about specifically "five feet", but I think the 2007 versions of both NFPA 13 (for sprinkler piping etc.) and 24 (for private fire mains etc.) include the clause immediately after those you've quoted above to the effect, "10.6.4  Where adjacent structures or physical conditions make it impractical to locate risers immediately inside an exterior wall, such risers shall be permitted to be located as close as practical to exterior walls to minimize underground piping under the building."
