Required length for MA Building Code when using 2x12 for ceiling joists?

Question

I've looked forward and backward through the 780 CMR 7th edition and cannot find anywhere the required length when using a 2x12 for ceiling joists. I need this information in order to provide a quote and would greatly appreciate any information you can give me or if you can point me in the right direction.
