Does state or federal government offer financial aid to build an Accessory Dwelling Unit (or Auxiliary Dwelling Unit. Example: an apartment or tiny home on the same property as a single-family home...basically, a small guest house) for an elderly person to house their home health care aide?
I think one major issue would be zoning, if said property has enough property distance from neighbors to erect something the size of a double car garage, and to use for occupancy.
