Fair Housing Council of San Fernando Valley v. Roommate.com, LLC

Roommate.com (defendant) ran a website letting users post personal details — including sex, sexual orientation, and family status — to help find roommates. Fair housing councils (plaintiffs) sued, arguing the site's practice of prompting, matching on, and publishing those preferences violated the Fair Housing Act (FHA), which bars discrimination based on protected traits in the sale or rental of a "dwelling." The district court agreed and granted summary judgment to the plaintiffs, enjoining the practices; Roommate.com appealed.
