The Structures and Addresses Framework is a routinely-updated statewide spatial database of primary structures, buildings and their addresses. The geodatabase consists of a point feature class and a related metadata table. Both structure and address points are contained in the point feature class, along with associated attribute information.

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

Structures and address data are used for everything from planning to economic development 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, elections management, broadband internet access, and postal and package delivery.

Structure/address point GIS data, along with road centerlines and emergency service boundaries, are a key component in Next Generation 9-1-1 (NG9-1-1) systems. MSL is supporting Public Safety Answering Points (PSAPs) for the transition to NG9-1-1 by helping them validate and aggregate their GIS for NG9-1-1 and helping coordinate the statewide GIS datasets required for NG9-1-1.
