Answer 56

New buildings require accessibility if: they are (1) places of public accommodation (businesses with a public-facing entrance like banks, hotels, restaurants, doctor’s offices, etc.) or (2) commercial spaces that need to be accessed by people with disabilities.

Renovated existing non-compliant buildings require accessibility if: (1) a primary function area is part of the alteration (the teller station of a bank, the lobby of a hotel, the dining room of a restaurant, or the waiting room of a doctor’s office). . . if making the room accessible will exceed 20% of the total cost of the building alteration, then the ADA requirement is considered “disproportionate” and you can cap your accessibility-related spending at 20%, provided you make ADA alterations in this reasonable order of priority until you hit 20% of your budget: entrance; route to the primary function area; at least one unisex restroom or one restroom for each sex serving the area; public telephones serving the area; drinking fountains serving the area; other elements.
