Sweed, Philip, House

Why it's listed
This two-storey house at 301 Keokuk Street in Petaluma was built in 1892 of local redwood by master builder Samuel Rodd for Philip Sweed, a German-born dry-goods merchant. It combines Queen Anne and Eastlake design, with three cross gables, bands of square and fishscale shingles, spindlework, and a wraparound arcaded porch. Inside, original redwood woodwork, wallpapers, graining, brass hardware and an early central heating system survive. The house sits on a double corner lot within the Oak Hill historic residential area. Sweed served on the city Board of Education for nearly thirty years, from 1893 to 1925, and a school was named for him. The house is the one remaining building in Petaluma that best reflects his work in education. It is also considered one of the finest and least altered Queen Anne residences in the city. The basement was converted to an apartment in 1974 without exterior changes, and the exterior was restored in 1982.
Significance in brief: The house is argued to be one of the best residential examples of Queen Anne style in Petaluma and remains largely unaltered inside and out (Criterion C). It is also the building that best illustrates the achievements of Philip Sweed, who served on the city Board of Education from 1893 to 1925 (Criterion B, Education).

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.
