I have a question regarding joist overhangs.
I'm building a freestanding cantilever design deck next to my pool. The posts are about 2' high and sit on top of 12" diameter concrete piers with anchoring hardware, etc.
There is about 2'-6" of joist overhang from the last supporting beam to the edge of pool deck. The total length of joist is about 10', with the span in between the two beams at 6'-6".
Our building office references the 2012 IRC, and according to that I shouldn't be able to do more than 1/4 of the 6'-6" span (i.e., max joist overhang should be just over 1'-6").
BUT.... I just called my inspector, and he said it's actually all good, and that...
A) Rather than a 4:1 span to overhang ratio it's actually 3:1 and even 2:1 is acceptable if there is no roofing structure overhead bearing down on the deck.
B) The way the joist span is calculated in these equations is the TOTAL length of the joist, not the length of the joist in between the two beams.
I'm wondering if I should just roll with it and build as is, or possibly throw one more post down in there to create a short diagonal beam that attached to the main beam with an angled joist hanger and some diagonal bracing?
Thoughts?
