CYB uses basketball rules adopted by CIF (California Interscholastic Federation) and NFHS (National Federation of State High Schools Association) as the foundation for the basketball we play. A copy of the NFHS "Rules by Topic" is at each CYB game.
Here are the links to these rules:CIF Basketball RulesNFHS Basketball Rules
However, CYB does have a few select modifications specific to our league to help promote the recreational nature of our league. These relate to player participation, fair play, and modifications to help out our younger divisions. Please see the section above for the CYB Maroon Book.
