Main Plumbing Vent Location?

[ACADuser]

Working on a house where the entire roof of the main house is a roof terrace.

Can you suggest a code approved location for the single 3" vent stack?

I have looked at the code but nothing but a vent 7 feet tall above the roof deck works.

And it can not be in the Daylight plane for the local restrictions.

First gut reaction is you probably need to provide a vertical element to house the vent.  I have worked on multifamily housing with roof decks and this was handled with a "chimney" to house these vents.  But, perhaps others can chime in.

As Jim said, you just need something to house it.

• False Chimney
• Metal Sculpture
• Shade Structure
• Outdoor Kitchen
• Wind Screen
• etc.

Use your imagination

Ironically, I'm currently working on a similar project with a roof deck and I haven't given vents one thought until now.  Thanks for bringing to my attention Alan.

Yea this is a weird one.

The max height is 30 feet above flood and a 7 foot vent stack would break that by 4 feet.

Great suggestions though. I may have to do some roof area just for the vent.

You might double check the zoning code to see if certain projections above height limit are allowable, eg. chimneys, antennae, etc.  Just a thought.

 

Here's an example from project I'm working on.

What about something simple like this?
