Mosaic tile and 18 inch ceramic tile are good for those of us living in special needs housing. 
•    PRO: You’ll sail right along on this hard, solid surface in your wheelchair,

•    CON:  if you’re using your walker and take a tumble, don’t expect a soft landing; you could end up flat on your derriere and maybe wearing a cast for a few weeks

•    PRO:  if you spill food or liquid on this surface, it’s easy for your caregiver to sweep up or mop up

•    PRO: Tile will also last longer than other types of flooring

What if hard tiles don’t work for your special needs housing budget? Look into:
•    Laminate –
o    PRO: Attractive

o    PRO: Less expensive than ceramic and slate tile

o    PRO: Laminate patterns are available in both wood and stone.
   
•    Vinyl (sheet or tile) – (polyvinyl chloride)
o    PRO: Durable

o    PRO: Inexpensive

o    PRO: Variety of patterns and styles

o    PRO: Easy to install

o    PRO: Easy to clean
    Water resistant
    Durable

Two more options that work well:
 
•    Cement (painted or patterned)

•    Hard, flat carpet such as Indoor/Outdoor carpet

My partner Carole used ceramic tile and indoor/outdoor carpet in the living areas when she built her special needs house, and made sure that the ramped walkway was made of concrete. The indoor/outdoor carpet under the entryway soaked excess water from the wheels before they hit the tile floor inside.

When I began writing this, we found several websites dealing with flooring for special needs housing that will work for someone who has trouble walking and others that work best for wheelchairs. Take a look at findanyfloor and the ultimate source the American Disabilities Act website.
