The purpose of the Safe at Home Act is to ensure that executive agencies and federal courts recognize and comply with state address confidentiality programs. These programs are designed to protect the addresses of individuals, particularly those who may be survivors of domestic violence, stalking, or similar situations, by allowing them to use a designated address instead of their actual physical address. Key provisions of the Act include the requirement for all executive agencies and federal courts to accept a designated address provided by participants in these confidentiality programs.
