Simpson-Vance House
Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
Built in 1892 on a corner lot near downtown Eureka, this two-and-a-half story Queen Anne house was constructed for James Simpson, a contractor and builder with a large family. An octagonal corner tower with a conical cap and iron finial, stacked bays and pedimented gables define its form, while spindlework, cutout ornament, brackets and a decorated frieze cover the portico, windows and bays. E. C. Mowry, who ran a moulding mill, was named as architect in a 1893 newspaper account. In 1902 the house passed to John M. Vance, heir to railroad and timber interests, and was redecorated in an elaborate showpiece style. Later uses included a home for older women and a halfway house, the latter bringing major interior changes. Exterior alterations such as added stairs and attachments are considered reversible, and many interior features survive. The house is valued as a fine, largely intact example of late nineteenth-century architecture in Eureka.
Significance in brief: The nomination argues the house is an outstanding example of Queen Anne architecture, with an octagonal corner tower, gabled bays and lavish applied ornament. It is considered one of Eureka's finest examples of the style and was found architecturally significant in the Eureka Freeway Survey. It is also associated with builder James Simpson and the prominent John M. Vance family.

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.
