对于SDU来说,plumbing也是有要求的,其中一个最重要的要求,也是inspector必检查一项,在Building Code规定如下:
Second units must also have their own separate water shut-off valves. This allows plumbing work or repairs to be done in one unit without affecting water flow in the other.
作为SDU的Bedroom是有窗户大小的采光要求的,那么,Living and dining rooms也是有最小的采光要求的,Building Code要求Living and dining rooms的采光要求最小为5%;而Laundry room, kitchen, bathroom是没有采光要求的,所以他们的Windows not required。
