Tenants with disabilities have protections under the Federal Fair Housing Act Amendments. Under anti-discrimination laws, you are "disabled" if you have a physical or mental impairment that interferes with a major life activity, such as working, in a substantial manner. If you have a disability, your landlord must make reasonable accommodations to facilitate your using the apartment, such as supplying grab bars in your bathroom, allowing a companion animal, or providing a parking spot close to your unit. To be required, the accommodation's cost to the landlord cannot be excessive, significantly alter his or her business operation, or pose a danger or discomfort to other tenants. Start by sending a certified letter to the landlord with your request and why you ask for it. If the landlord refuses, you can take legal action to enforce your rights.
