I was reading the California Building Standard Commission site and it seems like California will be adopting the NEC 2008 by July of 2010.
and it will called (California Electrical Code 2010)

anyone knows about this?

Yes..... all of that, but it will not be in effect until January 1, 2011.

And then the County or City building departments would have to adopt the 2010 Calif Code...they are the AHJs, with the exception of hospitals, where the State of Calif also issues permits.

Nothing like some states, where the state govt is the AHJ for areas where no county or city pre-empts the state. In Calif, every county and most incorporated cities have building depts that issue permits and do inspections. Some very rural counties (yes, there are some in Calif) contract with adjacent counties for inspections.

The area in which I do most of my work, Sacramento, is on the 2007 Calif Code, which is the 2005 NEC with some additional requirements. Many relate to seismic (earthquake) activity, and health care occupancies.
