(2) Prohibit any postsecondary educational institution, whether private or public, from providing housing accommodations reserved for either male or female students so long as no individual person is denied equal access to housing accommodations, or from providing separate housing accommodations reserved primarily for married students or for students with minor dependents who reside with them.

(3) Prohibit selection based upon factors other than race, color, religion, sex, marital status, national origin, ancestry, familial status, disability, or other basis prohibited by the Unruh Civil Rights Act.

(4) Promote housing accommodations on a preferential or quota basis.

(b) Nothing contained in this part relating to discrimination in housing shall affect the nondiscriminatory enforcement of state and local public nuisance laws, provided that those laws do not otherwise conflict with the provisions of this part.
