Where to take your vehicle for a smog check in Pasadena

Pasadena does not have its own smog check stations. You will need to go to a Bureau of Automotive Repair (BAR) certified station in Pasadena or a nearby city. These are private repair shops and service stations that the state has licensed to perform the test — they are not government-run facilities.

To find a certified station near you, use the BAR's online station locator at bar.ca.gov. Enter your zip code (91101 through 91109 for Pasadena) and the tool will show you every certified station within a few miles, along with their phone numbers and hours. Most stations charge between $30 and $50 for the test itself, though prices vary.

You can also call ahead to confirm the station is open and has availability. Some stations get busy during peak times (late afternoon, weekends, and the last week before your registration expires), so scheduling a time slot can save you a wait.

Key Takeaways

  • Pasadena has no dedicated smog check facilities, so you must visit a Bureau of Automotive Repair certified station in Pasadena or nearby cities.
  • Use the BAR's online locator at bar.ca.gov to find certified stations by zip code, including their hours and phone numbers.
  • The test costs between $30 and $50 at most stations and takes 10 to 20 minutes once you arrive.
  • Your vehicle must pass the test to renew your registration; if it fails, you have 30 days to fix the problem and retest at no additional charge.

What documents and vehicle information you need to bring

Bring your vehicle registration or renewal notice. The station needs to confirm your vehicle's model year, make, model, and engine type to run the correct test protocol. If you have lost your registration card, bring your driver's license and the vehicle's Vehicle Identification Number (VIN) — the station can look up your registration in the state system.

You do not need an appointment at most Pasadena-area stations, but calling ahead is still smart. Some stations require you to bring proof of payment (a credit card or cash) and your driver's license for identification. A few stations in the area ask you to fill out a brief form with your contact information before the test begins.

How the smog check test works and what happens after

The test itself takes 10 to 20 minutes. A technician will connect your vehicle to a dynamometer (a machine that measures emissions as your engine runs under load) or perform a two-speed idle test depending on your vehicle's year and type. You will sit in the vehicle while this happens. The technician will not drive your car off the lot.

Once the test is complete, you will receive a printed result when ready. If your vehicle passes, the station sends the result to the California Department of Motor Vehicles (DMV) electronically, usually within 24 hours. You can then renew your registration online, by mail, or in person at a DMV office in Pasadena (located at 3737 East Colorado Boulevard).

If your vehicle fails, you have 30 days to repair the problem and retest. The second test is free at the same station. You do not need to pay the $30 to $50 fee again. Keep your failure notice — you will need it to show the station when you return for the retest.

Vehicles exempt from smog checks in Pasadena

Not every vehicle registered in Pasadena needs a smog check. Vehicles model year 1975 and older are exempt. Electric vehicles (battery-only, not hybrids) are also exempt. Vehicles registered as classic cars or street rods with a special registration type do not require smog checks.

Vehicles model year 2000 and newer are exempt in their first four years of registration. After that, they must pass a smog check every two years. Vehicles model year 1976 through 1999 must pass every two years with no exemption period.

Check your registration notice to see whether your vehicle requires a smog check. The notice will state "Smog Check Required" or "Smog Check Not Required" clearly at the top. If you are unsure, call the DMV at 1-800-777-0133 and provide your vehicle's VIN and registration number.

What to do if your vehicle fails the smog check

A failed smog check means your vehicle's emissions are above the state limit for your vehicle's model year. The station will give you a detailed report showing which emissions (nitrogen oxides, particulate matter, or hydrocarbons) exceeded the limit. This report is not a repair order — it is diagnostic information to help a mechanic understand what needs fixing.

You have 30 days to repair your vehicle and return to the same station for a free retest. Common repairs include replacing a faulty oxygen sensor, fixing a vacuum leak, or replacing a clogged air filter. If repairs cost more than $500, you may be able to defer your registration for one year while you save for the work, though you must request this from the DMV before your registration expires.

If you repair your vehicle at a shop other than the testing station, bring the repair receipt to the retest appointment. The technician will run the test again at no charge. If you pass the retest, the station sends the result to the DMV and you can renew your registration.

Timing your smog check before registration renewal

Your registration renewal notice will show your expiration date. You can take your smog check test up to 60 days before that date. The result is valid for 30 days, so plan to test no earlier than 60 days out and no later than 30 days before expiration.

If you test too early (more than 60 days before expiration), the result will not be valid for registration renewal and you will have to test again. If you wait until after your registration expires, you cannot legally drive your vehicle until you pass the test and renew. The DMV will not renew your registration without a passing smog check result on file.

Pasadena stations are typically busiest in the final two weeks before the end of the month and in the last week before expiration dates. If you can test in the middle of the month or earlier in your renewal window, you will likely face shorter waits.

Frequently Asked Questions

Can I renew my registration online if I pass the smog check?

Yes. Once the station sends your passing result to the DMV (usually within 24 hours), you can renew online at dmv.ca.gov, by mail, or in person. You do not have to wait for a physical certificate — the electronic result is sufficient. Online renewal is the fastest option and takes a few minutes.

What if the smog check station closes before I can retest after failing?

You have 30 days from your failure date to retest, not 30 days from when the station closes. If a station closes permanently, you can retest at any other BAR-certified station in Pasadena or nearby. Bring your original failure notice from the closed station. The new station will honor the 30-day retest window and charge no fee for the retest.

Do I need a smog check if I just moved to Pasadena?

If you are registering a vehicle in California for the first time, you do not need a smog check for the initial registration. You will need one for your first renewal. If you already have a California registration and moved to Pasadena, your smog check requirement does not change — it depends on your vehicle's model year and how long it has been registered, not where you live.

Can I get a smog check waiver if my vehicle fails?

California offers a Smog Check Referee Program for vehicles that fail twice in a row after repairs. A referee station (different from a regular testing station) can issue a waiver if they determine the vehicle cannot pass despite reasonable repairs. Referee stations in the Pasadena area are listed on the BAR website. You must fail twice first — one failure does not may have access to you for a referee visit.

What happens if I drive with an expired registration because I failed the smog check?

Driving with expired registration is illegal and can result in a fine of $100 to $200. If you fail your smog check, you must complete repairs and retest within 30 days to keep your registration valid. If you cannot meet that important date, contact the DMV about a one-year registration deferment (available only if repairs exceed $500).
