Smog check stations in Glendale and how to find one

Glendale has multiple smog check stations scattered across the city, but you cannot straightforward walk into any repair shop. You need a station licensed by the California Bureau of Automotive Repair (BAR) to perform either a regular smog check (for most vehicles) or a STAR station smog check (for newer or lower-emission vehicles). The difference matters because STAR stations use less stringent testing and cost less, but your vehicle must meet their age and emissions requirements.

The fastest way to find a licensed station near you is the official BAR station locator at bar.ca.gov. Enter your zip code (91201, 91202, 91203, 91205, 91206, or 91207 for Glendale) and filter by station type. You will see the station name, address, phone number, and whether it is a regular station or STAR station. Call ahead before you go — stations have different hours, some require appointments, and some are currently closed or no longer operating despite appearing in the database.

If you cannot find an open station online, call the BAR Consumer information Program at 1-800-952-5210. They can tell you which stations are currently accepting customers and whether your vehicle qualifies for STAR testing, which usually costs $20 to $30 less than regular testing.

Key Takeaways

  • Only California Bureau of Automotive Repair licensed stations can perform smog checks in Glendale — you cannot use a general repair shop.

  • The official BAR station locator at bar.ca.gov shows which stations are in Glendale and whether they are regular or STAR stations.
  • Call the station before you go because hours vary, some require appointments, and some listed stations may no longer be open.
  • If you cannot find an open station, the BAR Consumer information Program at 1-800-952-5210 can direct you to one currently accepting customers.

What to bring and what the test costs

Bring your vehicle registration and a valid photo ID. The station will need to see proof that your vehicle is registered in California. Have your odometer reading available if the station asks for it, though most modern stations read it electronically during the test.

A regular smog check costs between $30 and $70 depending on the station and your vehicle type. STAR station tests cost $20 to $50. Some stations charge extra if your vehicle fails and you return for a retest after repairs — ask about retest fees when you call. A few stations waive the retest fee if you had the repairs done at their shop, but this is not universal.

You do not need an appointment at most Glendale stations, but calling ahead saves time. Some stations have walk-in hours only during certain times of day, and a few require appointments during peak seasons (typically March through May, when registration renewals pile up).

When your vehicle needs a smog check

California requires a smog check when you register a vehicle for the first time in the state, when you renew registration after it expires, or when you transfer ownership to someone else. The test must be done within 30 days before you submit your registration paperwork to the Department of Motor Vehicles.

Vehicles that are model year 1975 or older are exempt. Vehicles registered as non-operational or with a planned non-operation status do not need a test. If your vehicle has a valid smog check from another state, California will not accept it — you must get one from a California station.

If you fail the test, you have 30 days to have repairs done and return for a retest at the same station or another licensed station. The original test result is valid for 30 days, so plan your repairs accordingly.

What happens if your vehicle fails

A failed smog check means your vehicle's emissions are above California's limits for your vehicle's model year. The station will give you a printed report showing which emissions standards you failed. This report is not a repair order — it tells you what is wrong, but not necessarily how to fix it.

Take the report to a repair shop (not necessarily the smog station) and have them diagnose the problem. Common failures include a faulty oxygen sensor, a loose gas cap, a bad catalytic converter, or engine timing issues. Repairs can cost anywhere from $50 for a gas cap to $1,000 or more for a catalytic converter, depending on what is wrong.

After repairs, return to any licensed smog station for a retest. You do not have to go back to the original station. The retest must happen within 30 days of your original test, or you will need a new test.

STAR station requirements and how to know if you may have access to

A STAR station uses a less stringent test and is faster, but your vehicle must meet specific requirements. Your vehicle must be model year 2000 or newer, have fewer than 120,000 miles, and have no check engine light on. Some STAR stations also require that your vehicle passed a smog check within the last two years.

Call the STAR station before you go and give them your vehicle's year, make, model, and mileage. They can tell you in seconds whether you may have access to. If you do not may have access to for STAR, you will need a regular smog check at a non-STAR station.

STAR stations are usually faster — the test takes 10 to 15 minutes instead of 30 to 45 minutes — and they are less likely to find minor issues that do not affect emissions. If your vehicle is borderline on emissions, a STAR station may pass it where a regular station would fail.

How to read your smog check results

Your smog check result comes as a printed certificate or a digital record in the BAR system. The certificate shows your vehicle identification number (VIN), the test date, the station name, and whether you passed or failed. If you passed, the certificate is valid for 30 days for registration purposes.

If you passed, you can take the certificate to the DMV or submit it online when you renew your registration. If you failed, the certificate shows the specific emissions that exceeded limits — usually nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), or particulate matter (PM). This tells a mechanic what system to focus on.

Keep your smog check certificate or confirmation number until your registration is complete. The DMV will ask for proof that you passed when you submit your renewal.

Glendale smog check timing and registration important date

Your registration renewal notice will tell you the important date. You must have a passing smog check dated within 30 days before you submit your registration to the DMV. If your registration expires on June 30, you can get a smog check anytime between June 1 and June 30.

Do not wait until the last week of your registration month. Smog stations get backed up in the final days, and if you fail and need repairs, you will not have time for a retest. Plan to get your test done in the first or second week of your registration month.

If your registration has already expired, you can still get a smog check and renew, but you may face late fees from the DMV. The smog check itself does not expire — it is only valid for 30 days before registration, but once your registration is renewed, the test is complete.

Frequently Asked Questions

Can I get a smog check if my check engine light is on?

No. The check engine light automatically disqualifies you from any smog check, regular or STAR. You must have a mechanic diagnose and fix the problem first, then get the light cleared before returning to the smog station. This usually costs $50 to $200 depending on the problem.

What if I move out of Glendale after I get a smog check?

Your smog check is valid statewide for 30 days from the test date. If you move and need to register your vehicle in a different county, the same smog check works as long as it is within the 30-day window. After 30 days, you will need a new test in your new county.

Do I need a smog check if I am just renewing my registration online?

Yes. California requires a smog check for every registration renewal, whether you renew in person, by mail, or online. The DMV will not process your renewal without proof of a passing test dated within 30 days.

How long does a smog check take?

A regular smog check takes 30 to 45 minutes. A STAR station test takes 10 to 15 minutes. Most of the time is waiting for your turn, not the actual test. Arriving early in the morning or on a weekday usually means shorter waits than afternoons or weekends.

Can I get a smog check for someone else's vehicle?

No. The person whose name is on the registration must be present with a photo ID. The station needs to verify that the registered owner is testing the vehicle they own.
