The neighborhoods flanking the Upper Market Street corridor are primarily residential, with mixed use and commercial buildings located closer to Market Street. This results in the properties fronting on Market Street being almost entirely commercial. Buildings in the district are typically one to four stories in height, or between approximately 15 and 55 feet tall, with the majority being three-story structures about 40 feet tall. Those four story structures that are present are primarily grouped together near the center of the northwest block face of Market Street between Church Street and Sanchez Street. Nearly all of the buildings are of wood frame construction and clad in wood or stucco siding. A few examples of concrete construction and one brick masonry building are present. Victorian-era and commercial oriented architectural styles are the most widely represented, with the Classical Revival style most prevalent. Examples of later modern styles, such as International, Art Deco, and Art Moderne, are also present and help to illustrate the continual commerce-driven development of parcels along the prominent traffic corridor. In keeping with commercial stylistic conventions, rectangular, flat roofed structures are prevalent. Bay windows and facades organized into multiple bays are common features throughout the district.
