Building a room off the back of 2 story on the walk out side of the basement. Above this add on with be a deck off from the master bedroom and the deck will be supported by the roof of the add on, a shed type roof. Now the question: This room will have plumbing, running a vent threw the ceiling will be out of the question because all the roof area will be cover by the deck. Can I do a side wall vent and how does the code apply? We are in Michigan and the code says 3″ threw the roof but the side wall??? Do I have any other options????

Some codes have been updated to allow the use of one-way valves for venting, so you don't have to go outside at all. Check out http://www.studor.com/.
Why id it that the studor vents aren't more readily accepted? I know they're not allowed in Illinois, but have no idea why.
Crime wouldn't pay if the government ran it.
I don't know either. Maybe it just takes time for improvements to percolate into the codes. But these things are great for remodeling, where you want to vent plumbing without tearing up finished space above the remodel. If your local code doesn't yet permit them, you probably won't find them in your local stores. You can buy them off the web.
I was told by a plumbling inspector in chicago that any type of mechanical vent is prone to failure over time. I guess the issue is that people will not maintain the vent and it will get stuck in the open position allowing sewer gas into the structure (kind of like the shut off valves under a sink that are not used for 5 years and when you try to turn of the water the handel breaks off in your hand (or more likely the valve sprays water everywhere as you search for the main shut off)).
Why not turn the vent into the shed roof rafter area, and head it back to the orignal outside wall? From there you can run it straight to the roof. You need to use forty-five degree ells to make your turns, and keep the line headed up at all time, but you should have enough room in your rafter bays. Around here it has to go to a three inch stack before it penetrates the roof.
