Chemical engineering seems to be limited availability in CSUs – only at CPP, CSULB, and SJSU. It is available at most UCs (not UCSC or UCM).
http://www.sjsu.edu/admissions/impaction/impactionresultstransfer/index.html#Chemical says that SJSU admitted for chemical engineering applicants with three course requirements completed and 2.50 GPA.
https://web.csulb.edu/depts/enrollment/admissions/transfer-major-criteria/COE.html#q_g4 says that CSULB had a minimum 2.50 GPA for transfer to chemical engineering, but that only admitted for local applicants or if there was enough space available.
