How should the request be made? - The Network
Category: reasonable accommodation faq

You don’t need to use the language “reasonable accommodation,” though you should make the request in a way that a reasonable person would understand it as a request for a change or adjustment to housing policies, practices, or services because of a disability. It’s usually helpful to make the request in writing, to prevent misunderstanding. You may want to talk with the housing provider first to ask about their preferences on how you submit the request. For example, the Chicago Housing Authority has used this form in the past to assist residents in requesting a reasonable accommodation.
