Disabledworld and homeadvisor.com. show possible home repair Grant's and loans for disabled people. I'm not sure about cape cod local help though.
There are many programs to help with home repairs in each town there are affordable programs, Hac will direct you to their programs, there is Habitat for humanity, church programs, and MA office for disability has some. It depends on what you need done and if you are a homeowner or renter.
