Lisa R. Windsor, CA

I am acting on behalf of my parents for their home. We need to make their house accessible before my mother can come home from the hospital. The 3 priorities are a ramp into the house, a chair lift for the stairs, and an accessible bathroom. They have an unfinished bathroom attached to the master bedroom that currently only has a toilet installed so the bathroom will be less of a remodel and more of a fresh build.
