Change of Ownership Smog Check

Selling a car in California usually means handing over a valid smog certificate. Here is who owes it, how recent it has to be, and when nobody owes anything at all.

Certificate Valid 90 Days Usually Under 20 Minutes Results Sent to the DMV

A smog check is required when a vehicle changes ownership in California. The part people argue about is who is supposed to pay for it, and the law is not actually ambiguous.

The Seller Provides the Certificate

California Vehicle Code section 24007(b) puts it on the seller. The seller provides the buyer with a valid certificate of compliance. It is not a negotiating point in the way people treat it, although plenty of private sales end up splitting it anyway.

There is also a smog transfer fee that goes to the DMV to transfer the title. That is separate from the cost of the test and it is not something a station charges you.

How Recent the Test Has to Be

  • Private sale: the vehicle needs to have passed a smog check within the last 90 days.
  • Bought from a dealer: the vehicle needs to have passed within the past two years.

That 90 day window is the one that trips up private sellers. If the car passed four months ago, that certificate will not carry the sale. Get it tested again before you list it rather than after you have a buyer waiting.

When No Smog Check Is Needed

Two exemptions do real work here:

  • Vehicles four model years and newer do not require a smog check for a change of ownership. A smog transfer fee is still due to the DMV.
  • Transfers between immediate family members do not require a smog check at all.

So handing a car down to your son or your sister is not a smog situation. Selling that same car to a stranger is.

Sell the Car Faster With the Certificate Already in Hand

A private buyer looking at two similar cars will take the one that already has a current smog certificate, because it removes a job from their list and it quietly says the car is not hiding anything. Twenty minutes here before you list it is worth more than the same twenty minutes after a buyer has started asking questions.
