As a condominium corporation, store owners elect representatives to form a management board, which oversees the operation of the mall. Pacific Mall was designed by Wallman Clewes Bergman Architects, who built the structure in a combination of red brick, steel beams, and glass. The firm sought to create a "fabulous transparent building as different as possible from its surrounding," but rather than emulate Chinese architecture, sought to create a building that complimented Markham's suburban architecture. The mall's market-style interior with exposed roof trusses, pipes, and roof decks is described as "good representation of shed typology that is characterized by mass production, cost efficiency, and fast construction." The mall has two floors and a basement level that leads to an underground parking lot. The corridors of the main floor are arranged in a grid, with each corridor given a street name: corridors running north–south are named after streets in Hong Kong, such as Hennessy Avenue, Hollywood Avenue, Pacific Avenue, Queen's Avenue, and Nathan Avenue, while corridors running east–west are numerical, with numbers associated with affluence and luck in Cantonese, such as 218th Street and 188th Street. The center of the mall contains an indoor courtyard with a cathedral dome ceiling and stage that hosts cultural programs and trade fairs. The second floor contains a food court, entertainment center, medical offices, additional shops, and Heritage Town. On June 15, 2005, Pacific Mall and Market Village announced a 400,000-square-foot (37,000-square-metre) expansion that would see the construction of additional retail space, a luxury hotel, condominiums, and a multi-level parking structure that would bring the combined size of the malls to . In 2009, the developers announced they would instead demolish Market Village and construct a new adjoining mall, the Remington Centre. The project has faced numerous delays; while the expansion plan was endorsed by Markham City Council in 2011, it requires additional approvals from the municipal government of Toronto and a majority of the ownership of Pacific Mall, 40 percent of which is composed of individual retailers. Pacific Mall is noted for its sale of counterfeit and pirated goods, including video games, movies, music, electronic devices, cosmetics, apparel, and fragrances. In January 2018, the mall was listed as a notorious market by the Office of the United States Trade Representative, which noted that vendors in Pacific Mall “operate largely with impunity” despite requests for assistance from law enforcement. Pacific Mall management responded that they were "deeply disturbed" by the designation, and stated that they would give warnings to vendors who sold illicit goods.
