How it works for sellers and buyers
Sellers: walk in or book online. You approve a written estimate, we run the inspection for your model year, and you get the vehicle inspection report. With a 90-day window, it makes sense to test close to the sale.
Buyers: ask the seller for the smog certification. Buying from a private party? Ask to see it before you pay.
Family transfers: passing the car to a spouse, domestic partner, child, grandchild, parent, grandparent or sibling needs no smog check. A relative who bought the car on your behalf and never titled it in their name can't pass it on without a smog check, though.
If the car fails before it's sold
We walk you through the report. The car then needs emissions work at a station of your choice. BAR's Auto Shop Locator lists licensed stations that do emissions work, so you can pick one you trust. Back here within 30 calendar days, the $30 smog retest is $21.75, plus the $8.25 certificate on a pass.
If the car is newer, check the owner's manual: some emissions fixes may be covered by your manufacturer's warranty.

Makes we inspect
Our bay sees every make. Ford, Honda, Toyota, Volkswagen and Mazda turn up most often in our job photos, and the full brand list is on our vehicles we smog check page.
