Research Narrative

Landmark Context

Leiter II Building is tied to 403 S State St in the city's landmark file. Even in summary form, the record keeps together a construction date of 1891 and credits William LeBaron Jenney. It was designated on January 14, 1997. Leiter II Building already has a usable public frame for work on commercial development, architectural branding, and corridor and downtown change.

Leiter II Building is best read on the ground through storefront depth, upper-floor expression, and corner treatment, how the facade addresses pedestrian traffic, and later signage, infill, or reuse. That kind of fieldwork helps clarify how commercial architecture stayed visible even as the economic life around it changed.

Research Starting Points

Leiter II Building is easiest to push beyond designation through trade press and city directories, permit files and assessor records, and historic photographs and newspaper coverage. That is usually how a short landmark record turns into a fuller account of use, alteration, and neighborhood setting.

Leiter II Building still needs permits, photographs, and comparison, but the landmark record gives that work a stable point of return.
