National Register of Historic Places Designations
National Register Historic Districts
Tucson's nationally designated historic districts meet the criteria for, and have been listed in, the National Register of Historic Places (NRHP). A NRHP historic district is composed of multiple contributing properties that—as a collective whole—convey significance in terms of one or more of the following aspects of American history: (A) Association with historic events or activities, (B) Association with an important person in history, (C) Distinctive design or physical character, or (D) Potential to provide important information about prehistory or history. Each contributing property in a NRHP historic district must maintain enough of its original qualities to visibly convey its significance. These qualities of integrity include: location, design, setting, materials, workmanship, feeling, and association. A National Register Historic District must contain a minimum of 51 percent contributing properties within its boundaries.
As available, links to the documents related to each district's nominations are included. Where necessary, one large and multiple smaller files are provided of the same document in case file sizes are too large for those accessing this information using slower Internet speeds.

Individually Designated Historic Properties
Tucson's individually designated historic properties meet the criteria for, and have been listed in, the National Register of Historic Places.

An individually designated historic property also maintains enough of its original qualities that make it significant. These qualities of integrity include: location, design, setting, materials, workmanship, feeling, and association.
