Landlords Preferring Sec 8

[Account Closed]

have started seeing more and more landlords in socal suburbs actually declaring in ads that they prefer or give 'priority' to sec 8 applicants.

considering sec 8 is a 'program' providing an need-based housing voucher deemed countable as 'income'* for 'low-income residents', would preferring applicants of a type of income (in this case, the low-income housing voucher program called section 8) be in violation of FHA act or other federal or state (in my case, CA) statutes?
