Hope for Disabilities

For those of you who rent where you live and have anxiety of people coming in and out of your home because of something having to do with you diagnosis like urinary incontinence and odors in your apartment or house, what kinds of things do you do to help your landlord and others understand what you are going through and how they can possibly help ease your anxiety? Have you ever rented somewhere and had a switch in landlords where the one you had to begin with moved unexpectedly or the owner of the building sold the property and you had to get used to a new landlord quickly and you were afraid that they wouldn't understand your diagnosis and the challenges that might come with it?
