From the panhellenic green book, extension is campus dependent only in the sense if a campus panhellenic exists or not.

V. Agreement on Extension
1. National Panhellenic Conference believes that it is unethical for an NPC
fraternity to contact an institution and/or its students concerning the
establishment of a chapter where the institution fails to meet the NPC
requirements for a host institution, i.e., the institution must be a senior
college or university that is authorized to confer a bachelor’s degree
and that has received a satisfactory rating by the pertinent recognized
regional association of colleges and secondary schools.

2. The Proper Authority shall be defined as follows:
A. Where there are two or more NPC fraternities present on
campus, then a vote of those NPC fraternities as evidenced in
written minutes of the College Panhellenic Council (if organized)
shall constitute the Proper Authority or if there is no College
Panhellenic Council, then a separate vote of the NPC chapters
present on campus shall constitute the Proper Authority.

B. On campuses where there is one or no NPC fraternity and where
the administration is willing to recognize women’s fraternities,
letter from a senior level student affairs administrator shall
constitute the Proper Authority.

C. The NPC Extension Committee is the Proper Authority on campuses
where there is one or no NPC fraternity and the college administration
does not grant recognition to women’s fraternities but does not
discipline students for joining.
