The federal Fair Housing Act, as amended, recognizes seven protected classes: race, color, religion, sex, national origin, familial status, and disability. Undercounting or overcounting the list is a common exam trap, so the exact number is worth memorizing precisely.

The ADA generally addresses accessibility in public accommodations and commercial facilities (offices, retail space), which is a different focus from the Fair Housing Act's protections against disability discrimination in housing — it doesn't mandate retrofitting every private home, it certainly doesn't authorize screening out tenants (which would itself be illegal discrimination), and it doesn't create a licensing-style certification requirement.

Steering is illegally directing homebuyers toward or away from particular neighborhoods based on a protected characteristic like race or familial status — it has nothing to do with literally driving clients around, recommending lenders based on creditworthiness, or ordinary comparable-sales pricing advice.

Blockbusting is the illegal practice of persuading owners to sell, often at a lower price, by suggesting that a protected class moving into the neighborhood will hurt property values — it isn't about assembling adjacent lots, budget-based showing decisions, or a bulk-purchase discount.
