Only one stack vent

Under IRC 2003 can only one 2" pumbing vent service two bathrooms, the closest being 15 feet from the vent? No curcuit vent system is used, one story slab home.

Thank You


See section 3501

Thank you, Jeff

I see that the Air Admittance Valves (AAV) in section P3114 provides for the tub to be vented by the bathroom sink (AAV) within 6 feet. Is the correct?


Fixtures can share a common vent or AAV, yes, with the distance requirements based on that chart.
