What should you do if someone is trying to force/impose their OCD behaviors/fixations onto you?  

One of our tenants has been trying to enforce her OCD behaviors/fixations onto my family, who she is renting a house from (I live there as well right now). She wants us all to not shower, flush the toilet, or use the living room (not even tiptoeing around) past 10 pm, despite her doing all of those things whenever she wants (sometimes even late at night, like 11:30pm/midnight). We have tried to tell her to wear earplugs or use a sound machine so that she doesn't keep trying to control the rest of us and impose rules on us, but she claims that this "doesn't work for her". She also has other OCD habits, like obsessively using toilet paper and filling up an entire waste bin with used toilet paper every couple days, then allowing it to spill on the floor and refusing to empty it. We have asked her multiple times to please stop doing this, or at least clean up after herself, but she ignores us and keeps doing it. She has admitted to having OCD. It almost seems as if her OCD fixations are controlling her life, but instead of getting help and addressing it, she is trying to impose her situation onto the entire house. Advice on what to do?
