How can I get free housing grants or inexpensive house contractors?

Question:My grandmother's house is more than 50 years old and it is a small old wood house that really needs remodeling. The city wont let her rebuild on the property but she can remodel. Due to a car accident she is in a wheel chair and the house is not handicapped accessible at all. Alot of the wood is rotten and there are cracks and holes. Bascially the whole house needs to be fixed. She doesnt have the money for renovations or to pay high loans. I want to find housing grants for her or either an inexpensive contractor that maybe does payment plans or some sort.
Thanks

If you are in the United States try contacing your local Community Action Coalition. You might also contact the local Habitat for Humanity offices as well as local churches to see if they have any programs to help with this type of thing.
