A1 Smog Test is at 507 Broadway # A, El Cajon, CA 92021, in San Diego County. Phone: (619) 579-1947.

Is A1 Smog Test a STAR-certified station?

Yes — state Bureau of Automotive Repair STAR program records (refreshed 2026-08-02) list A1 Smog Test (BAR license #243316) as STAR-certified. Every listing on FindStarStation comes from those records.

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.

What does STAR smog check mean?

STAR is BAR's higher-standard certification.

  • Stations meet stricter equipment requirements
  • Directed vehicles must use STAR
  • Look for the STAR seal at the station

Per BAR (bar.ca.gov/smog-check).
