"Rural community." Is this a small town of x population, but it has local codes and ordinances? Is this on tribal lands? Is this a settlement of, say, 50 people living outside the city limits? What's the level of government that you have to deal with?
"Indian Nations participate in special needs housing programs".
Have you tried looking up which tribal jurisdiction your community is in? I could be wrong, but I wouldn't expect the Cheyenne-Arapaho to have a whole lot to do with a special needs housing program if it's located in Choctaw territory. You might look at this map:
www.okladot.state.ok.us/maps/tribal/2010_Tribal_Jurisdiction_Map.pdf
and approach the tribal jurisdiction that best applies to your specific location as to what kind of special needs housing programs you can opt into, and what their requirements are.
If you're just interested in reaching out to someone with a housing voucher, you might contact whatever tribal council is in charge of your territory and reach out to them as to how to get on their program. For example, if it was Choctaw, you might start by reading up here--
www.choctawnation.com/rental-assistance-program
but obviously, that wouldn't be the place you'd look if you were talking Muscogee, although they might have some information that would translate into other CDIB-required programs. (Certificate of Degree of Indian Blood) (ie, one person's tribal affiliation gives precedence over another based on whose lands you're in, but you need to be affiliated with someone in order to participate in the first place, if that makes sense. So in Choctaw land, a Choctaw-affiliated candidate for rental assistance gets bumped ahead of an Osage-affiliated candidate when you're in Choctaw land, but the reverse may be true if you're in Osage territory.)
