How far can floor joists overhang?
Joist Cantilevers 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).
When floor joists are load bearing They should not be cantilevered more than?

How far can a joist overhang a beam?
The distance your joists can safely cantilever or overhang a drop beam is determined by the size of the joists, the wood type and grade of the lumber and the spacing between joists. Many building departments limit joist cantilevers to 24″ maximum.

Can pressure treated lumber be used for floor joists?
Can you use a pressure treated lumber for a floor joist? – Quora. Yes, PT lumber can be used for framing, including floors. The allowable stresses of PT lumber are lower than non-treated lumber, which means it can not span as far. Also, PT lumber is corrosive, so connections need to be such that they resist corrosion.
