The CA Smog Check divides the State into four different smog check "Program Types": Enhanced, Partially Enhanced, Basic, and Change-of-Ownership Areas. The county in which a vehicle is registered will determine which type of smog check program the vehicle falls under.
Vehicles which are registered in Basic smog test program county can obtain a smog check in any county within California. Vehicles which fall under the Enhanced program area can only obtain a smog check in an Enhanced county.
Currently Ventura county is under the Enhanced Smog Check Program. El Dorado county is a Basic smog check area. A vehicle registered in El Dorado county can obtain a smog check in Ventura; the opposite however can not be done.
