Many California cities also passed laws to harass the Chinese. San Francisco, for instance, passed an ordinance in 1870 that prohibited anyone form occupying a sleeping room with less than 500 cubic feet of breathing space per person. This "health law" allowed the police to make raids on crowded tenements in Chinatown and roust out any sleeping Chinese residents who were violating the ordinance while they slept.

不仅如此，那时加州许多城市都通过了排华法案，以旧金山为例，1870年那里通过一条法令，"禁止一位华人占有一间超过500立方英尺呼吸面积的卧室"，这项"健康法律"允许警察对拥挤不堪的华人出租屋进行深夜突袭，并可以将在沉睡中触犯了法律的中国移民扔到大街上。
