Every State has a State Historic Preservation Office (SHPO, or "Shipo"), which administers State-level programs related to the Federal National Historic Preservation Act of 1966, and other Federal legislation. Most States, including Michigan, also have their own preservation laws, which are administered by their SHPO. Michigan's State Historic Preservation Officer is Brian Conway.
SHPO has several responsibilities under these laws, including:
- Processing applications for National Register of Historic Places nominations and National Historic Landmarks nominations
- Processing applications for State and Federal Historic Rehabilitation Tax Credits
- Performing Section 106 Review - any project that involves expenditure of Federal funds must be reviewed to determine whether it has the potential to disturb archeological, cultural, or historic resources
- Providing advice and support (and occasional grants) to local historic districts
- Hearing appeals of decisions by local Historic District Commissions
