2 feet and 6 inches
According to the new span tables and IRC provisions, cantilevers can extend up to one-fourth the backspan of the joist. This means that joists, such as southern pine 2x10s at 16 inches on-center, spanning 12 feet are allowed to cantilever up to an additional 3 feet (see illustration, below).
Thereof, How far can you cantilever a deck over a beam?
*Beams may cantilever at each end up to ¼ of the of the actual beam span. For example, a 16′ beam span can cantilever a maximum of 4′.
Also to know is, What is a cantilevered balcony? Cantilevered balconies These are balconies constructed in a manner so that the balcony protrudes from the face of the building without any visible supports other than the fixing to the face of the building. The weight and imposed loads are supported by cantilevering the structure off the wall.
Subsequently, question is, How far can you cantilever a 2×8 beam? Good working rule is that a cantilever should not exceed 4 times the height of the joists. 2×8= 7.25 inches high x 4 = 29 inches.

Are cantilever decks safe?
Weakened framing creates a life safety hazard. Decks or balconies may collapse with people on or below them. Cantilevered decks should be viewed with caution. If you are technically inclined, you can use a ladder if necessary to examine the cantilevered joists at their point of penetration through the wall.
How does a cantilever balcony work?
In modern lightweight-wood frame construction, these balconies and decks are often carried by cantilever beams, supported by the building wall on one side, unsupported on the other; and counterbalanced by an extension of the cantilevers to beams inside the floor-ceiling assemblies inside the building.
How much can you cantilever a deck?
According to the new span tables and IRC provisions, cantilevers can extend up to one-fourth the backspan of the joist. This means that joists, such as southern pine 2x10s at 16 inches on-center, spanning 12 feet are allowed to cantilever up to an additional 3 feet (see illustration, below).
How much load can a 2×8 support?
2,200 lbs. Also, how much weight can a 2×8 joist hold? some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24″ oc and reallllly short spans only (5 or 6 feet ).
Can you attach a deck to a cantilever?
Chuck Lockhart A deck ledger cannot be attached to cantilevered house framing. … Install a beam with posts and footings along the house end of the deck, just as you would at the outside of the deck. The beam can be built into the floor system—say a double or triple rim joist—or it can be placed beneath the deck joists.
How far can a beam extend past a post?
Beams are permitted to cantilever past the end posts up to one-quarter of the beam span between posts. I like to use this provision when sizing beams. Often I can reduce the span between posts slightly by cantilevering the beam.
