Downtown Development Authorities, or “DDAs,” are authorities created by a municipality for purposes of economic development. Whether a city, village, or township is faced with blight or merely wants to boost its economic growth, a DDA can help. The laws governing DDAs are set out in MCL § 125.1651 et. seq also known as Public Acts 197. If you are considering a DDA you absolutely have to get a copy of this Act and read it carefully. While the Act may be a bit dry in parts, it is vital to read and follow its provisions in order to create a successful DDA.
