It means that a house or apartment needs to have features like wider doors, ramps, and lower counters so that wheelchairs can get through easily. This way, people with disabilities can visit peoples' homes without having to worry about not being able to fit through the door or navigate the space. It also helps with things like making it easier for people in wheelchairs to use sinks and bathrooms.
