SDSU now has a 2 year on-campus requirement for all Freshman and Sophomore non-local students. It does seem more residential since many students that live off-campus will live in close proximity of the campus.
In general, most CSU’s are considered commuter campuses since they were established to give local area students access to a quality education. SLO and Chico state are more residential due to their more isolated locations.
