Hands down he best deal in San Francisco. Came in at 1pm on a Thursday without an appointment, the man that helped me was very nice and efficient. I showed him a coupon that I found on their website and the smog was $39.95 plus $8.25 certificate and $1.75 shop fee, totaling to $49.95 CASH ONLY. I was asked to come back in 30 min, came back in 25 min and my car was done. read more

SF Star Smog - Smog Check Stations Near Me - San Francisco, California

Easy peasy Why I book it here +'s: + Takes appointments for Star Smog Tests $79.95 + Friendly service + Next to MCD if you want fries Why I don't book it here -'s: - Can't think of a reason not to Have been coming here annually for last few years and will continue read more

My car did not pass the first time. But because the technician did such a terrible job of explaining what the problem was, I did not do the correct things to fix the problem. So when I came back for the one and only re-test, it failed again. I found someone else at an auto repair shop who correctly interpreted the error. Then I was able to fix it. But...I had to pay another $40 to SF Star Smog. So, this is perhaps the cheapest smog check. But I guess I got what I paid for. read more

Fast service and competent & friendly staff. Turnaround time is about 20 mins and under $50 with a coupon. Can't beat that

They only took 10 minutes to do my smog. The technician was very professional and polite. He also noticed my tires had some damage that needed to be repaired. He saw I'd gotten them from Costco and told me "they are probably under warranty, so you should take them to Costco and save some money". I did that and he was right! I had no idea! Also by booking my (same day) appointment online, the cost was a total of $49.95 with their coupon, so I saved maybe $30 with them. Definitely this is my go-to place. read more

Very efficient and very reasonable price compared to other smog test centers in San Francisco.

If u want honesty don't come here. Guy (owner David) give u a price and then the price is different at the end. I ask if him does he still honor a discount for Yelp check in. He makes up shit like only 2 times. Don't waste your time. Sunny as hell no waiting area and cars go in and out of the gas station hella dangerous while u waiting. Go other places around Potrero Ave for better pricing. I Don't write review but feel like I had to say something. read more

The bad news is that my car failed the first test. The good news was that it failed because the battery had been disconnected/replaced recently so the "fix" wouldn't cost anything. More on that later. I went back a few weeks later, they honored the free re-test and we passed. Both times they were pretty quick, and if you do need to pass some time there is the MacDonalds and the whole Potrero shopping center. So I recommend this place. Good price, but they only take cash with the Yelp discount. There is an ATM in the convenience store, with a $3.50 fee. Now, if you fail because your car's computer doesn't have a full "driving cycle" you'll need to let your car idle for over 5 minutes in the morning. Then you'll somehow need to slow down from 55 to less than 20 without using the brake. Safest place that I found to do this was the Sneath Lane southbound exit on 280. Stay to the left once you hit the exit. read more

I had a quick fast smog service without an appointment! They file with the DMV. Pro tip - if you have AAA you can go to the Potrero AAA right after to register your car. read more

Even though I wasn't able to get my smog check done because of a Service Engine Soon light, I still wanted to leave a positive review. The guy who helped me was super friendly, professional, and took the time to explain why they couldn't proceed with the test. He didn't rush me, didn't try to upsell anything, and showed genuine care even though I wasn't a paying customer this time. It's rare to find that kind of honesty and good attitude in auto shops these days. I'll definitely be back once the issue is resolved, just based on the great customer service alone. Highly recommend! read more

It worked You can also go in the gas station and get chicken or beef tamales for 2.99 each. Theres a bench to rest at while they smog check. Nice spot read more

I have been going to this place for years, because I don't drive my car very much, the test doesn't pass, every time the gentleman that works there tells me "go drive on the freeway for an hour and come back and we'll do the test again". This inspector that works at this place is such a gentleman, very kind and attentive and courteous. He treats everyone that goes there with respect and dignity. I have never gone anywhere else to have my vehicle smog tested. And I will continue to give this place my business. This was happened today 01-05-2025. read more

Great service. The technician Wei Shen was very nice and professional. This location is in the Shell Station on the corner of Potrero & 17th street. Wei has been there for 10 years.

A few places are cash only. read more
