The Structures & Address Framework is a statewide database of structure and address points obtained from local, state, federal, and private data providers.

Structures and address data are used for everything from natural resource planning to recovery from natural disasters including floods, wildfires and earthquakes. Furthermore, address data are essential for delivery of government and private services such as the dispatch of emergency services, broadband internet access, and postal and package delivery.

Structure/address point data are also a key component in Next Generation 9-1-1 (NG9-1-1) systems. As such, MSL is attempting to raise awareness and educate our address data providers about NG9-1-1 and the impacts it will have on how they manage and use their address datasets. For more information, see our NG9-1-1 GIS Resources page.
