Landlord and tenant legal rights often vary depending on state and/or local laws. Some states offer more protections and rights, while other states may have less detailed regulations. Both tenants and landlords involved in rental disputes may benefit from consulting an attorney who specializes in landlord and tenant law to determine what rights may apply in their location. There are, however, some general rights that apply to nearly all rental tenants and landlords. These rights include the right to be protected from discrimination in the rental process. Federal laws protect tenants who have been denied tenancy, subjected to unfair rules and practices, or unlawfully evicted on the basis of discrimination. Tenants have the right to sue a landlord under federal law in the event of rental discrimination. Tenants also have the right to live in a rental unit that is safe and habitable. Rental units must comply with building and health codes, and landlords must maintain and repair rental properties as necessary. A tenant may pursue legal action against a landlord who refuses to make necessary repairs. Tenants also have a general right to privacy, and in most cases a landlord must give proper notice before entering a rental unit.
