CAPS Universal Design Principles & Accessibility Standards 2

Question 1

In the context of aging-in-place design, 'visitability' primarily refers to:

Accepted Answer

Basic accessibility features that allow people with mobility impairments to visit or live in a home

Answer

Visitability refers to a minimum set of accessibility features — including a zero-step entrance, wide interior doors, and a main-floor bathroom — that allow people with disabilities to visit or reside in a home.

Question 2

For a forward approach at a kitchen or bathroom counter, what is the minimum knee clearance height required per ANSI A117.1?

Accepted Answer

27 inches

Answer

ANSI A117.1 requires a minimum knee clearance of 27 inches in height beneath counters and work surfaces to accommodate a person in a wheelchair approaching forward.

Question 3

According to ADA accessibility standards, the maximum height for operable controls (such as light switches) in a forward reach configuration should not exceed:

Accepted Answer

48 inches

Answer

The ADA requires that forward reach controls be no higher than 48 inches above the finished floor, ensuring they are reachable by wheelchair users and people of shorter stature.

Question 4

Lever-style door handles are strongly preferred over traditional round doorknobs in aging-in-place design primarily because they:

Accepted Answer

Require less grip strength and hand dexterity to operate

Answer

Lever handles can be operated with a closed fist or wrist, making them accessible for individuals with arthritis, limited grip strength, or reduced dexterity — a key consideration in aging-in-place modifications.

Question 5

What is the maximum threshold height permitted at exterior doorways under ADA accessibility standards?

Accepted Answer

1/2 inch

Answer

The ADA limits threshold heights at exterior doorways to 1/2 inch maximum, and thresholds between 1/4 and 1/2 inch must be beveled to reduce the trip hazard.
