Renter's Credit for Full-Time Student in California

[Mochina]

My son is a full-time student at Cal Poly University San Luis Obispo who lived for more than half of 2023 in a rental house off-campus.  His "permanent" address is his home address in Torrance, CA.  The California TT for renter's credit asks "Did you pay rent for at least half of 2023 on property in California that was your principal residence"  I am uncertain about the distinction between "permanent" and "principal." Is he still entitled to renter's credit?
