How Much Does a Smog Check Cost in California?
California doesn't set a price for the inspection itself — stations set their own rates, so the cost varies by station, region, and vehicle type. Expect somewhere in the neighborhood of $40 to $90 for the inspection, plus one fee the state does control: an $8.25 certificate fee charged once your vehicle passes.
Why do prices vary from station to station?
A test-only station that can't perform repairs, a full-service shop that can test and fix problems in one visit, and a high-volume shop in a competitive area will all price differently. Because the rate isn't regulated, it's worth calling two or three nearby stations before you go — a difference of $20 or $30 between two stations a few miles apart isn't unusual. Our city listings show every licensed station in an area with phone numbers, so comparing is a matter of a few calls.
Does my vehicle qualify for a fee instead of a test?
Newer vehicles often pay an annual smog abatement fee ($20–$25 depending on model year) at registration instead of getting tested at all — see our exemptions guide for which vehicles qualify. Vehicles four model years old or newer being transferred between owners similarly pay an $8 smog transfer fee instead of a test.
Total cost by scenario
| Scenario | Typical cost |
|---|---|
| Routine renewal inspection (pass) | $40–$90 inspection + $8.25 state certificate fee |
| Renewal, vehicle 8 model years or newer | $20–$25 annual abatement fee, no inspection |
| Ownership transfer, vehicle 4 model years or newer | $8 transfer fee, no inspection |
| Ownership transfer, vehicle older than 4 model years | $40–$90 inspection + $8.25 certificate fee |
| Immediate-family transfer, any age | No fee, no inspection |
What do repairs cost if I fail?
Repair costs after a failed test vary enormously depending on what's wrong — a loose gas cap costs nothing, a failed catalytic converter can run into four figures. Before paying out of pocket, check whether you qualify for the state's Consumer Assistance Program (CAP), which offers income-eligible drivers repair assistance and vehicle-retirement payments for vehicles that failed a Smog Check. Amounts and eligibility rules are set by the Bureau of Automotive Repair and change from year to year, so confirm current figures directly at bar.ca.gov/cap before assuming you qualify. See our guide on what to do after a failed test for the full process.
How do I get the best price?
Because the test fee is unregulated but the pass/fail result is not, shopping on price alone can backfire if it means using a station with a reputation for false failures to upsell repairs. A station's STAR certification (shown as a badge on every listing here) is a reasonable quality signal on top of price — STAR stations meet higher performance standards set by the state.
