The arrival of Asian immigrants to the Seattle area in the 1880s, many living in crowded rooming houses, led to concerns from the city council, which passed a cubic air ordinance in 1886 requiring 500 square feet of air space per resident. By the early 1900s (decade), Asian immigrants from Japan and China who settled in Seattle were typically the men from the family, who moved to the city's Chinatown and Nihonmachi districts and lived in SROs. Chinese immigrants came to Seattle to work as miners, cooks, railway laborers and cannery workers. These SRO residents used the restaurants, bath-houses, and barbershops to meet their living needs while they worked in Seattle-area industries. Some SROs aimed at Asian residents had a bath-house in the basement to serve Japanese immigrant clients.
