The law is clear in California, they should not have given you a ticket, however if you had wrote a letter saying you are not a student, they claim they would dismiss the tickets for you.

EDUCATION CODE
SECTION 67300-67302
67301. (a) The Board of Governors of the California Community
Colleges and the Trustees of the California State University shall,
and the Regents of the University of California may, adopt rules and
regulations prescribing requirements similar to those provided by
Section 22511.5 of the Vehicle Code and all other applicable sections
of the Vehicle Code relating to parking exemptions for disabled
persons, as defined by Section 295.5 of the Vehicle Code, and
disabled veterans, as defined by Section 295.7 of the Vehicle Code.
The rules and regulations shall include authorization to park for
unlimited periods in time-restricted parking zones and to park in any
metered parking space without being required to pay any parking
meter fee or to display a parking permit other than pursuant to
Section 5007 or 22511.55 of the Vehicle Code, provided those spaces
are otherwise available for use by the general public. The adopted
regulations shall authorize parking at campus facilities and grounds
by students with disabilities and by persons providing transportation
services to students with disabilities. Except as otherwise
provided in this section, students with disabilities and persons
providing transportation to students with disabilities shall be
required to display a valid parking permit, if applicable, for the
campus attended. Nothing in this section prohibits the adoption of
rules and regulations providing greater accessibility for students
with disabilities and persons providing transportation services to
those students.
The adopted rules and regulations shall exempt students with
disabilities and persons providing transportation services to these
persons from any applicable parking restrictions in areas including,
but not limited to, metered parking spaces and parking facilities
designated for use by students, faculty, administrators, and
employees.
(b) The Regents of the University of California may provide, and
the Trustees of the California State University shall provide, and
the Board of Governors of the California Community Colleges shall
adopt rules and regulations requiring the governing board of each
community college district to provide, visitor parking at each campus
of the university or district at no charge for a disabled person, as
defined by Section 295.5 of the Vehicle Code, or disabled veteran,
as defined by Section 295.7 of the Vehicle Code, or as defined by
each segment's policy concerning the provision of services to
students with disabilities, whichever is more inclusive, and for
persons providing transportation services to individuals with
disabilities. Whenever parking designated for a disabled person is
provided on any campus of the University of California, the
California State University, or a community college district in a
facility controlled by a mechanical gate, that university or district
shall also provide accommodations for any person whose disability
prevents him or her from operating the gate controls. These
accommodations may be provided by making arrangements for disabled
persons to be assisted in the operation of the gate controls, or
through other effective and reasonable means the university or
district may devise. Nothing in this subdivision shall be construed
to require the replacement or elimination of special parking
facilities restricted for the use of disabled persons located on the
campuses of these universities or districts.
It is the intent of the Legislature that community college
districts shall utilize the proceeds from parking fees charged to
community college students and employees to offset costs incurred by
these districts in accommodating disabled persons pursuant to the
requirements of this section.
(c) The Board of Governors of the California Community Colleges
and the Trustees of the California State University shall, and the
Regents of the University of California may, establish procedures for
the purpose of conducting biennial audits to determine whether
individual campuses are in compliance with all state building code
requirements relating to the location and the designation of minimum
percentages of available campus parking spaces for use by students
with disabilities, as determined by guidelines of Section 14679 of
the Government Code, Section 2-7102 of Title 24 of the California
Code of Regulations, Part 40 (commencing with Section 40.1) of Title
24 of the Code of Federal Regulations, Section 1190.31 of Title 36 of
the Code of Federal Regulations, or their successor provisions, or
any other applicable provisions of law, whichever provides the
greater accessibility for disabled persons.
