Kosy Knook Court
Why it's listed
Kosy Knook Court is a bungalow court at 830 Brooks Avenue in Pasadena, made up of five identical 24-by-24-foot wood-frame houses built in 1922. Architect G.W. Tombleson designed the group and the Hartman Brothers built it. Two pairs of bungalows face each other across a central concrete walkway, with a fifth unit at the rear facing the street. Each house has clapboard siding, an asphalt shingle jerkinhead roof, a small portico with paired wood posts, and paired six-over-one wood windows flanking the entry. The court is valued as one of the best Pasadena examples of the detached, narrow, enclosed bungalow court form. It also shows the Colonial Revival style of the early 1920s, in which details once seen on large mansions were adapted to modest homes. The bungalows remain virtually unaltered and keep their original lantern-type light fixtures, although the two rear garages have been demolished.
Significance in brief: The court is argued to be one of the best examples of the bungalow court form in Pasadena, representing the detached, narrow, enclosed court type. It is also highly exemplary of the Colonial Revival style as applied to a bungalow court, with jerkinhead roofs, columned entry porticoes and multi-paned windows. The form notes that such details, once found on high-style mansions, had become popular on modest homes.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
