Elder assistance

Hey everyone - my bestfriends parents are going through a particularly hard time right now with their healthy rapidly declining within the last two weeks. Long story short we are going to need to renovate their place a little for him to come home from health rehab (bars on shower, walk in shower versus tub to step over, railings etc). Does anyone know of services or non profits in the area that would be able to provide assistance or second hand items? I know I’m preaching to the choir when I say times are tough and money is tight so anything I can to to help point them in the right direction would be so appreciated.
