What to bring, what to expect
-
Check engine light off
If it's on, the car will not pass. We can still run the test, and if it fails we can diagnose what needs attention before the next one.
-
Warm it up
Drive 15 to 20 minutes beforehand so the engine is fully up to temperature. Make sure the gas cap seals.
-
Bring the DMV notice if it says STAR
Nothing else is needed for a standard smog. We look the vehicle up. Title transfers and out-of-state cars don't need extra paperwork.
What's included
- Regular biennial smog certification
- STAR and test-only (DMV-directed), same price as a standard smog
- Change of ownership and title transfer
- Out-of-state vehicle registration
- Hybrids, tested like any gasoline vehicle
- Diesel smog, $110
- Failed a smog elsewhere? We diagnose, repair and re-test here
- Results sent to the DMV instantly
What to expect
Pull in, hand us the keys, and we call you when it’s done. Most tests take about 20 to 25 minutes once the vehicle is in the bay. Wait time varies with the line, and an appointment cuts it down. You get the printed certificate and a copy of the inspection report.
We’re STAR certified by the Bureau of Automotive Repair, so the DMV can send you here for any test type, including STAR-directed tests that regular stations can’t run. Every test is done by a licensed inspector on a state-monitored analyzer.
Registering a salvage vehicle? The DMV usually wants a smog and a VSSI inspection. We’re licensed for both, so it’s one drop-off.

If your car fails
You get a report showing the cause: a code, a readiness problem, an emissions reading, or a visual item. From there:
- Needs a repair. Our technicians diagnose and fix emissions problems here (check-engine codes, catalytic converters, EVAP leaks, O2 sensors) and re-test once it’s done. If we do the repair, the re-test is free. If you or another shop do the repairs, the re-test is charged, because we have to verify the repair and run the full test again.
- Not ready. If it failed only because the readiness monitors weren’t complete, see below. That re-test is free.
- Expensive repair? Ask about the state’s Consumer Assistance Program (CAP). We’ll point you to it if your vehicle qualifies.
"Not ready": what readiness monitors mean
Your car’s computer runs self-tests as you drive. If the battery was disconnected or codes were cleared recently, some of those tests haven’t finished and the car reports not ready. That’s a fail, even with no check engine light.
We test the vehicle as it arrives. If it fails only for readiness, drive it normally for a few days (a mix of city and highway driving) and bring it back. If the monitors are complete and nothing else comes up, the re-test for that readiness fail is free.
Diesel smog check
California requires a smog on 1998-and-newer diesel vehicles up to 14,000 lb GVWR, on the same two-year schedule as gasoline vehicles. Diesels are tested through the on-board computer plus a visual inspection. It’s $110, walk-ins are fine, and most diesel pickups and vans are done in under an hour.
Title transfers and out-of-state cars
Selling a car in California requires a smog within 90 days of the sale. Bringing a car in from another state requires one before the DMV will register it. Both are the standard $58 test here. No special appointment, no extra paperwork.
Aftermarket parts
Aftermarket exhaust, intake or tuning parts must carry a CARB EO number. A non-CARB part fails the visual inspection even if the tailpipe numbers are fine.

Do I need an appointment for a smog check?
No. Walk in any time we're open, Monday through Saturday. Most tests take about 20 to 25 minutes once the vehicle is in the bay. Wait time varies, and an appointment cuts it down.
How much is a smog check?
$58 for a standard gasoline or hybrid vehicle, and that includes the state certificate. STAR and test-only smogs are the same price. Diesel smogs are $110. Vehicles where an engine doghouse or similar access panel must be removed to perform the inspection are the standard price plus 0.5 hour labor. Vehicles that need additional disassembly are quoted before testing.
What if my check engine light is on?
The vehicle will not pass. We can still run the test as-is, and if it fails we can diagnose the vehicle to find what needs attention before your next test. The diagnostic is a separate service from the smog.
What happens if my car fails?
You pay $49.75 for the failed test (no certificate is issued) and get a report showing what tripped it. If we do the repair, the re-test is free. If it failed only because the readiness monitors weren't complete, drive it and come back for a free re-test. If you or another shop do the repairs, the re-test is charged.
Do I need to bring anything?
Nothing for a standard smog. If the DMV sent a notice saying STAR or test-only, bring it so we run the right test type.
How long is a smog certificate good for?
90 days. That's the window the DMV gives you to complete a title transfer or registration after you pass. Regular renewals are due every two years for most vehicles.
How often do I need a smog?
Every two years for most gasoline vehicles more than eight model years old, when ownership changes, and when registering an out-of-state car in California.
Do you smog hybrids?
Yes. Hybrids are tested like any other gasoline vehicle, at the standard $58 price.
How much is a diesel smog?
$110. California requires smog on 1998-and-newer diesel vehicles up to 14,000 lb GVWR. Call with the year and model if you're not sure yours is due.
