A STAR Certified Test Only smog inspection center occupying Suite B of the multi-tenant 4694 Voltaire St building, OB Smog Test Only is restricted by its Bureau of Automotive Repair classification to inspections only — no diagnostic repair, no parts installation, no certification of work the station itself performed. Failed inspections trigger outside-repair referrals to Ozzie's Auto Repair on Sunset Cliffs Blvd for catalytic converter, oxygen sensor, EGR valve, and EVAP canister work that brings the vehicle back into emissions compliance for retest. STAR designation matters because the California DMV directs registrations flagged by the Bureau of Automotive Repair's gold-shield audit program to STAR-only stations, with all other renewal smogs accepted at any BAR-permitted station regardless of STAR status. The station tests gasoline-powered passenger vehicles, light trucks, motorhomes, and plug-in hybrids using OBD-II readiness monitor scans rather than tailpipe sniffer testing for vehicle-year ranges that qualify under current BAR protocols. Title transfer paperwork frequently moves through Notary Branch to pair the freshly-issued smog certificate with a notarized California REG 262 bill of sale for private-party vehicle transfers within the 90-day cert validity window. The most demanding inspections are diesel-powered light trucks under California's expanded smog program, which require visual emission-control component verification, OBD-II readiness checks, and opacity standards beyond the standard gasoline-vehicle workflow.
