And, what is most relevant for present purposes, Congress added three safe-harbor provisions, specifying that "[n]othing in [the FHA]" prohibits (a) certain actions taken by real property appraisers, (b) certain occupancy requirements, and (c) the treatment of persons convicted of manufacturing or distributing illegal drugs.

Nor does any provision in this subchapter regarding familial status apply with respect to housing for older persons.” §3607(b)(1).
“Nothing in this subchapter prohibits conduct against a person because such person has been convicted by any court of competent jurisdiction of the illegal manufacture or distribution of a controlled substance as defined in section 802 of title 21.” §3607(b)(4).
