About 30 minutes is a good starting point for a California Smog Check.
But if what you're really asking is:
"Can I get this done today without an appointment?"
For most 2000-and-newer vehicles at San Juan Auto Smog, the answer is yes.
Most newer vehicles are walk-in during our regular business hours.
Older vehicles are different.
We regularly inspect 1999-and-older vehicles, RVs, vans and heavy trucks, but we recommend making an appointment for those vehicles so we can plan the appropriate space, equipment and time.
If someone recently cleared your trouble codes or disconnected the battery, your emissions readiness monitors may not have completed.
We offer a reduced-fee pre-inspection that checks OBD-II readiness, active or pending trouble codes, and check-engine-light status before the official test.
That's fine too.
Leave your vehicle with us and pick it up later. If you live or work close to our Fair Oaks shop, ask us about a ride. When we have the staff and time available, we may be able to give you a ride to or from the shop.

For a typical newer passenger car, allow around 30 minutes plus any wait. Or drop it off and eliminate the waiting from your schedule altogether.
