If you will re-word you question, I will try to answer it for you. I am not sure what you mean by "put in a modification" (to the apartment itself, like a wheelchair ramp?), or "of my support" (financial? physical? What is the context?), or "get it lowered" (get WHAT lowered?)
Sorry I can't help you at this point, but feel free to provide a clearer question and I'll check back later to see if I can help.
