Summary for 933 15TH AVE / Parcel ID 2254501515 / Inv # 0

Historic Name: Common Name:
Style: American Foursquare - Craftsman Neighborhood: First Hill
Built By: Year Built: 1906
This is a typical example of American Foursquare architecture with Queen Anne and Craftsman elements. The structure’s design integrity has been somewhat compromised by alterations to the porch roof and the removal or addition of window and door openings.

This is one of approximately 2,200 houses that are still extant out of more than 5,000 that were built by the end of 1906 in Seattle’s Central Area, Eastlake, First Hill, Leschi, Madison Park, Madrona, and North Capitol Hill neighborhoods.

A complete permit history, and a complete record of ownership and occupation have not yet been prepared for this property; however, Harry Duelfer appears to have owned the structure from approximately 1929 until at least 1937. Olive Duelfer acquired the property in 1940.

This is a two-and-a-half story, clapboard and shingle clad, wood frame triplex on a concrete foundation, over a quarter basement.

The rectangular plan is capped by a hip roof with hip roofed dormers, moderate overhangs, open soffits, and exposed rafter tails

The windows and doors of this American Foursquare residence are characterized by patterns and details customarily associated with late Queen Anne design. The exposed rafter tails, and the built up Tuscan piers, are suggestive of emerging Craftsman sensibilities. A balcony (or roof deck) over the front porch, and the single door that once provided access to the deck from the upper level at the middle of the east (street) elevation, have been removed. The full width porch now has a hip roof.

The attic appears to have been finished or renovated recently. A large north facing dormer may not be original.

This structure was built as a single family residence in 1906 but altered for use as a triplex at some point after 1937 (there appear to be three mailboxes). The assessor's records indicate that the building is a duplex. The structure is located on the First Hill (west) side of 15th Avenue, but many would consider the property to be situated in the Central Area.
