California Plumbing Code 711.0 Suds Relief.
711.1 General. Drainage connections shall not be made into a drainage piping system within 8 feet (2438 mm) of a vertical to horizontal change of direction of a stack containing suds-producing fixtures. Bathtubs, laundries, washing machine standpipes, kitchen sinks, and dishwashers shall be considered suds-producing fixtures. Where parallel vent stacks are required, they shall connect to the drainage stack at a point 8 feet (2438 mm) above the lowest point of the drainage stack.
Exceptions:
(1) Single-family residences
(2) Stacks receiving the discharge from less than three stories of plumbing fixtures
My question: If I have a 3 story, slab-on-grade building, at my ground level is my stack considered "less than 3 stories", because at the point that my first floor kitchen sink ties into the stack, the vertical "stack" portion is only receiving discharge from the second and third floor?
