I looked through apendix "G" of the 2000 IRC, but it doesn't address depth. I also looked in chapter 31 of the IBC, but it is silent as well. I know that here in Utah the state health department has regulations governing pools, such as a minimum depth before diving boards are installed. You might want to try your state board of health.
Sorry...I wish I had more for you.

Scott, I checked the 2001 Calif. Bldg Code and nothing is stated for maximum depths. The minimum depths for pools with diving boards is listed for public pools. The swimming pool info in Chapter 31B of the CBC.
