Key, George, Ranch
Also known as: Key Ranch
Why it's listed
This 2.25-acre citrus ranch in Placentia, Orange County, preserves the home, grounds and outbuildings of rancher George Benn Key, who bought his first 20 acres in 1893. He built the two-story frame house in 1898 and remodeled it about 1908 with pillared porches, a stone-columned trellis, fireplaces and hand-carved woodwork. A garage dates to 1908 and a tractor shed to 1945. Gardens, old trees and surrounding orange groves give the property a rural setting. Key worked as superintendent of an early Valencia orange ranch and helped organize the Placentia Orange Growers Exchange, a leading packing house whose growers used the Sunkist label. The ranch holds extensive collections of farming and equestrian equipment, citrus labels and family memorabilia displayed in a museum-like setting. The nomination presents it as the best surviving example of an early Orange County orange ranch and of the way of life that accompanied the citrus industry.
Significance in brief: The nomination argues the ranch is the most thoroughly representative of the citrus ranches that made Orange County famous, with its house, grounds, outbuildings and large collections of farming equipment and family memorabilia. It also contains one of the oldest surviving homes in Placentia and reflects the early Valencia orange industry, in which Key was a pioneer and a founder of the Placentia Orange Growers Exchange.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
