Introduction to Smog Inspections
Smog inspections, or smog checks, are mandatory for certain vehicles in California to ensure they meet emissions standards, helping reduce air pollution. These checks are administered by the California Bureau of Automotive Repair (BAR) and are required for vehicles more than eight model years old every two years, with some exceptions.
Average Cost and Variations
Based on available data, the average cost of a smog inspection in January 2025 is around $65.97. However, this can vary:
Vehicle Type: Diesel vehicles may cost more to test than gasoline ones.
Location: Regional differences, such as higher costs in urban areas due to business expenses, were evident from shop-specific pricing.
Inspection Type: STAR inspections, required for certain vehicles under six years old with GVWR less than 14,000 pounds, may cost more, with specific stations charging higher rates.
Interestingly, the average cost of a smog inspection in January 2025 is around $65.97 plus a $8.25 state certificate fee, making a total of $74.22, the range is around $40 to $90, reflecting shop-to-shop variations. Additionally, shops may charge an Electronic Transmission (EFT) fee of $1 to $3 for transmitting vehicle data, and the state certificate fee is mandatory only upon passing, adding to the total cost for successful inspections.
Always asking for the total charges upfront is a smart way to avoid "bait and switch" practices, where a service provider might quote one price but later add extra fees. By knowing the full cost from the start, you can make an informed decision and avoid any surprises down the line.
Check renewal notices for special instructions, such as STAR station requirements.

Keep Vehicle Inspection Reports (VIR) for records, especially if electronic transmission fails
Importance of Regular Inspections
Regular smog checks are essential not only for compliance with state regulations but also for improving vehicle performance and fuel efficiency. They help identify vehicles emitting excessive pollutants, contributing to cleaner air in California.
