The historic district’s narrative mentions it twice:

Six percent of residences within the Salt Lake City Northwest Historic District are duplexes (also known historically as double houses), with another one percent being historic apartment buildings. Approximately half of the duplexes were built between 1890 and 1910, and are found both along the main streets and in residential courts between 500 and 800 West. Stylistically, these early duplexes come in two varieties: the urban model with a flat-roof and decorative brick parapets; and the more domestic-looking, hipped or gable roof structure. Despite being rental units (or perhaps because they are rentals), these duplexes have survived relatively intact with only minor changes, such as the replacement of the classical porch columns with wrought iron. Brick masonry was used for most of these buildings, however there are a few frame examples such as the duplexes at Tuttle Court. The remaining half of the duplexes date from the Bungalow era or the post-World War II period, and with few exceptions, are found in the western half of the district. Many, especially later, duplexes are found on corner lots as part of rental buffers for subdivision development. A few are frame-sided or stucco Bungalows, including one Langton Park triplex, but most are brick structures from the late 1940s.

Multiple-family housing began to appear in the district in the early 1890s. According to one report, in April of 1888, there was a “scarcity of rentable houses and a great demand for them,” particularly four-room cottages for small families. The most popular type of multiple-family housing was the double house, or duplex. Most were brick, some were frame, and the earliest examples resembled Victorian cottages with gable roofs and wood ornamentation. The Tuttle Court complex, built by Mary Anne Taylor Tuttle (1832-1924) around 1895, has four of the oldest and best-preserved frame examples in the district. The original owner of multiple-family housing was often a builder or businessman who lived nearby. The circa 1904 brick duplex at 745-747 West Jackson Avenue was built by William H. Jones (?-1935?), a carpenter who lived at 635 West 400 North; and the circa 1900 brick triplex at 216-218 North 800 West was built by Kay Bridge (1876-1952), a plasterer, living at 666 West North Temple.
