Federal and state laws allow for certain rights for tenants to ensure their safety and wellbeing, and also to protect them from unfair rental practices. Specific laws vary by state, and the type of tenancy may also offer particular rights for tenants. General rights include the right to live in a safe and clean structure that complies with housing codes, and a tenant's right to basic privacy within their rental space. Rights for tenants also include the right to defend themselves in court and make a case against a threatened eviction. Additional rights for tenants with disabilities are mandated in the federal Americans with Disabilities Act (ADA), and include protection against discrimination and the right to use necessary helper animals. The Protecting Tenants at Foreclosure Act of 2009 outlines specific rights for tenants residing in recently foreclosed properties, giving them the right to continue living in the property until their lease expires.
