Does a STAR smog check cost more than regular?

Not automatically — BAR doesn't set a price difference between STAR and regular stations. Each shop posts its own price.

  • STAR and non-STAR stations both set their own posted prices — there's no state-mandated STAR markup
  • Some vehicles are required by your DMV renewal notice to test at a STAR station, regardless of price
  • See our posted price on-site or on our services page

Prices are set per station, not by BAR — see our posted price for the exact cost.

How often do I need a smog check in California?

Every two years for most vehicles.

  • At sale or transfer
  • First 8 years exempt for new cars
  • Out-of-state imports need one

Per California DMV registration rules.
