Well in my area if you put a level from the chimney to the roof, that line needs to measure at least ten feet.

Call your local building department for the correct answer in your area.

10 feet had sorta stuck in my head so thanks for re-affirming this. I was afraid of that.....I'm 8 feet away from the roof now so will need to add another section of scaffolding to make the 10 feet. Thanks!

If you are referring to a conventional masonry chimney on a sloped roof, it must be two feet above the height of a horizontal line drawn from top of the flue to the point at which that line touches any portion of the structure within ten feet of the nearest point on the flue. For other types of roofs and some types of manufactured vent systems the requirements can be a bit more complicated.

Exactly, as well as 3' minimum where it penetrates through the roof. The 3' rule is when the chimney is located at the peak (like it should be.......... )

Your Regs look a bit stricter than ours.

Thanks everyone! If the weather holds out for a day or so, I will add the additional blocks to meet this requirement. It means adding one more section of scaffoldling to reach this high but now is the time to do it with every thing else in place. The good thing is I am right at the height where the hip roof angles upwards to the peak, so making that 10 foot rule won't take more than a block or two. Add my bracing and the 'cricket' and I'll be in good shape here.
