Building Code Requirements<br />
Safety Factor: Joist Spacing<br />
The building code does not specify on-center joist spacing but does require<br />
spacing that will produce specified deflection performance for the loading<br />
conditions.<br />
Joist spacing is most often determined by owner/builder preference or the<br />
desire to “value engineer” the floor system.<br />
Traditional joist spacing is 16” o.c.<br />
Stronger engineered joists have made possible new on-center spacing<br />
options of 19.2” and 24”.<br />
The building codes set only minimum requirements for floor system<br />
performance.<br />
Value engineering recognizes the ability of fewer, stronger joists to meet<br />
code minimums.
