Herget, Carl, Mansion
Why it's listed
Built in 1912 on a full city block at 420 Washington Street in Pekin, Illinois, this two-and-a-half-story brick mansion is a local example of Classical Revival residential design. Its hipped green slate roof, full-height entry porch with Corinthian columns, segmental pedimented doorway and symmetrical facade are typical of the style's early wave of popularity. A side verandah with Doric columns and a roof-line balustrade adds to the composition, and the original wide brick sidewalk remains. Inside are quarter-sawn oak floors, marble fireplaces, a ballroom in the attic and a large arched stair window. The Peoria firm Hewitt & Emerson prepared the plans in 1912, and the original blueprints were later returned to the house. No other Classical Revival residences are known in Pekin. The house later became law offices with few interior changes. A rear screened porch, a pool and a rebuilt garage are the main additions. The house was listed for its architecture.
Significance in brief: The nomination argues the mansion is a well-preserved local example of Classical Revival residential architecture under Criterion C. It features a full-height porch with Corinthian columns, a symmetrical facade and a side verandah with Doric columns. It was designed by the prominent Peoria firm Hewitt & Emerson, and no other Classical Revival residences are known in Pekin.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
