Why it's listed

Built in 1910 at 414 East Chapman Avenue in Orange, California, this six-room wood-frame house was designed by Ina Ainsworth Butler, an artist, for her father, Lewis Ainsworth. Ainsworth was a Vermont-born businessman who joined the 1849 Gold Rush, later farmed in Iowa and Kansas, and settled in Orange in 1900. There he organized the town's first planing mill and built the Ainsworth Building on the Plaza Square. The house is symmetrical, with three gables over a curved front veranda and sheet-metal scrollwork made to resemble wood. It combines bungalow simplicity with Colonial Revival touches and Victorian-era ornament. It also represents the post-pioneer growth of Orange beyond the original Plaza core, in an area now mostly given over to modern development. The City of Orange acquired the property in 1976 and a citizens' committee is overseeing its restoration as a museum of 1910 Orange.

Significance in brief: The house is locally significant for commerce, settlement and architecture. It is tied to Lewis Ainsworth, an early 20th century businessman in Orange. It is a remnant of the post-pioneer settlement pattern near the Orange Plaza. It is also a notable example of the transition from Victorian to bungalow residential design.

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.
