House at 1233 Wentworth Ave.
Why it's listed
Built in 1917 for Lydia C. Edmonds, a widow, this one-and-one-half-story bungalow on Wentworth Avenue in Pasadena's Oak Knoll subdivision was designed by architect Arthur S. Heineman. It interprets the English Cotswold cottage in a California setting. Low horizontal massing, arcing and hipped roofs with rolled eaves, and wood shingles give it that character; the shingles replaced thatch that originally covered the roof. A broad entrance porch merges into a porte-cochere, supported by squat brick piers and blocky wooden supports. Decorative barge board and half-timbering add detail. Inside, a Batchelder-designed fireplace anchors the living room, and the dining room keeps its wood paneling, pocket doors and built-in cabinetry. A two-bay garage and a lattice gazebo also contribute to the property, while a 1954 swimming pool does not. The house was listed for its architecture, as an excellent example of Arts and Crafts residential design in Pasadena that retains its integrity.
Significance in brief: The nomination argues the house is an excellent example of a Cotswold cottage within the Arts and Crafts single-family residence property type in Pasadena. It embodies the design, craftsmanship and materials of Arts and Crafts residential architecture and retains integrity. Distinguishing features include the shingle roof with rolled eaves, low horizontal form, wide porch/porte-cochere, decorative barge board and half-timbering.

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.
