Everyone should be able to access all entrances, regardless of ability. It’s common to see separate main entrances and an accessible entrance because of a flight of stairs or some other barrier. This is not characteristic of universal design, and it’s segregating.
Zero-step entrances aren’t just for wheelchair users. Think about pushing a stroller or walking with young toddlers, carrying groceries or luggage, or moving furniture and new appliances.
Ironically, some accessible entrances require more effort than necessary if a greater distance is required for people to travel. Individuals who are unable to walk long distances because of pain or decreased endurance can often find that the intended “easier pathway” is difficult, despite more obvious barriers (e.g., steps) not being an issue. Plan entrances and the routes travelled to access the entrances well.
