I inspected a 1925 home (wow! wood shingle siding, not stucco) which had been extensively added on to over the years (crawl space indicated that there might have been five separate additions). This sewer vent went along exterior, openable windows, which I didn’t like.
Any comment from our code gurus about this type of installation?

David,
You've got your separation distance crossed up.
The main thing to remember is 10' horizontal separation or 2' higher than the top of any door, openable window or air intake opening (don't forget soffit vents and other building openings which could allow intake air into the building). Rarely will you find where the 4' will apply - if the plumbing vent termination is below any of the above openings, it must be at least 4' below that opening.
From the 2003 IRC.
P3103.5 Location of vent terminal. An open vent terminal from a drainage system shall not be located less than 4 feet (1219 mm) directly beneath any door, openable window, or other air intake opening of the building or of an adjacent building, nor shall any such vent terminal be within 10 feet (3048 mm) horizontally of such an opening unless it is at least 2 feet (610 mm) above the top of such opening.

David,
I'm confused.
The 4' did not apply either, but you posted it. So I figured you may have missed the rest of it. My apologies for thinking you missed that other part.
When I post code references I try to include the entire code section, because many people will read what is posted and not realize there is anything else to the code or any other requirements for that (whatever if being discussed).

Yes, the pipe terminated appropriately above the roof. I just have a concern with the pipe being so close to the openable window where various kids can lean out to talk to their friends and pull and push on the pipe at the same time, causing it to loosen, crack, etc., and various sewer gases then getting into the window. Maybe I’m just thinking too much? Maybe I need a margarita.

The 10 foot and 2 foot (3 feet UPC) part makes sense, but would anyone be happy with a vent terminating 4'1" directly below an openable window? UPC simply states 10' from (all other directions) or 3' above. I must have read the IRC paragraph a dozen times now and I just can't make sense of the 4' below part.

recommend another clamp near the elbow. Probably not "required" but might be a good idea.

Richard,
The IRC is also the first time I've come across the 4' below, everything else is 10' separation or (take your pick, this varies) either 2' above or 3' above.
If it were below, I would want it AT LEAST 10' away, and I'd really like it even further away (if below the window).
There is also the 'physical protection of the pipe' issue which no one brought up (me neither).
How was this flashed coming through the wall?
Being as this looks 'added on', how was it flashed going through the roof?
What kind of strapping is required in earthquake country?
How are you going to open those two windows in the corner? (Without hitting each other?)
