Tenant rights vary by state and local jurisdiction, and some locations offer more rights to tenants than others. Federal tenant rights that apply nationwide include the right to live in a safe and habitable dwelling that complies with building codes. Federal laws also protect tenants from discrimination and harassment in the rental process, and allow for specific rights to those with disabilities, including the right to have a helper animal on the premises if necessary. Tenant rights also include the right to take legal action against a landlord who fails to make necessary repairs or who keeps the rental property in an unsafe or unsanitary condition. A tenant may also pursue legal action if a landlord refuses to return a security deposit or makes illegal deductions to the security deposit. In the event of a dispute between a landlord and tenant, often an attorney may be consulted who specializes in landlord and tenant rights.
