I'm using two beams with floor joists on top in a cantilevered fashion. I'm curious as to what the maximum overhang would be using 16" spacing, and 2 grade for the following:
How far can I cantilever from a beam for a new planned deck? Let's assume 2x8 joists 16" oc over a doubled 2x10 beam. Here you can overhang max 3' with a 2"x8" SP 2 16 o.c. and no roof load. Code requires solid blocking over the beams when doing so. I would refer that question to your local building
Instead of having posts right next to the pool I want to cantilever the deck. Can I use double 2x8 joist and cantilever 4 feet with 8' going 4 to 1 max cantilever ratio is common in my area.

Maximum deck beam cantilever. Maximum deck beam cantilever post 98306 xzcz37 on Wed, 05/18/2005 - 03:14 . in . Cut back the deck to allow a reasonable overhang and forget about what could happen 8 to 10 years from now after weathering and rot has taken its toll on a creative framing experiment.
Updated span tables for decking, joists, and beams clarify the requirements for cantilevering portions of a deck. Anna The IRC permits cantilevers up to one-fourth the span of the joist, with the cantilever distance or overhang measured from the center of the supporting beam to the outermost framing material, typically the rim joist. The
This framing style is called post and beam, and the overhang is a cantilever. Now your deck can extend 17 out: a 14 span from house to beam plus a 3 cantilever.³ Nice. 17 ft Cantilevered Deck
the overhang will be past the 4x4 posts supporting the original deck. it will be made of 2x8 joists that are 3 feet long and will be atached with joist hangers to the deck and to the new end which is also 2x8.
The Typical Deck Beam Spans figures show that the beam span and cantilever measurements are taken from the center of the posts and not the face of the posts. There are other beam provisions and limitations in the 2015 IRC to take note of:
Re: How far can a deck cantilever? The cantilevers at Fallingwater Fallingwater's structural system includes a series of bold reinforced concrete cantilevered balconies; however, the house had problems from the beginning.
