How Much Are Smog Checks In California? A Breakdown Of Costs

As a California driver, you know that smog checks are mandatory to register your vehicle. But how much should you expect to pay for this emissions test? Smog check prices depend on factors like your car’s age and the test facility. This comprehensive guide will break down average smog check costs in California by county and key pricing factors.

If you’re short on time, here’s a quick answer: The average cost of a smog check in California falls between $30 – $50, with stations in major cities like Los Angeles and San Francisco on the higher end.

Average Cost of a Smog Inspection in California

When it comes to smog checks in California, the average cost can vary depending on several factors. Let’s break down the costs and give you an idea of what to expect.

Newer Vehicles vs. Older Vehicles

The cost of a smog inspection can differ between newer and older vehicles. Newer vehicles, typically those manufactured in the past six years, tend to have lower inspection fees. This is because they are equipped with advanced emission control systems that make them more environmentally friendly.

On the other hand, older vehicles might require additional testing and repairs to meet the state’s emission standards, leading to higher inspection costs.

County Variations

The cost of smog checks can also vary by county in California. Each county has the authority to set its own inspection fees within a certain range. For example, the average cost of a smog inspection in Los Angeles County might be different from that in San Francisco County.

It’s important to check with your local Department of Motor Vehicles (DMV) or visit their official website for the specific fees in your area.

Test-Only vs. Test and Repair Facilities

In California, there are two types of smog check facilities: test-only and test and repair. Test-only facilities are authorized to perform smog inspections but are not allowed to make any repairs.

On the other hand, test and repair facilities can both conduct inspections and fix any issues that may arise during the process.

The cost of the smog inspection at a test-only facility is generally lower compared to a test and repair facility. However, if your vehicle fails the initial inspection at a test-only facility, you will need to take it to a test and repair facility for further evaluation and potential repairs.

It’s worth mentioning that the average cost of a smog inspection in California can range from $30 to $50. In fact, dealers in California can’t charge more than $50 for a smog inspection, but they can charge an additional fee for the sticker or certification if your vehicle passes the test.

What Impacts the Cost of a Smog Check?

Several factors can influence the cost of a smog check in California. Understanding these factors can help you better anticipate and budget for the expense. Here are the key factors that can impact the cost of a smog check:

Vehicle Age

The age of your vehicle can affect the cost of a smog check. Older vehicles may require more extensive testing and repairs to meet California’s stringent emissions standards. As a result, the cost of the smog check for an older vehicle may be higher compared to a newer one.

Additionally, older vehicles may have outdated emissions control systems that require replacement or upgrades, which can increase the overall cost of the smog check.

Facility Type

The type of facility where you get your smog check can also impact the cost. Smog checks can be conducted at various types of facilities, including licensed smog stations, test-only centers, and STAR stations.

Each facility type may have different pricing structures based on the services they offer and the equipment they use. It’s a good idea to compare prices and services offered by different facilities to find the most cost-effective option for your smog check.


The county in which you reside or where the smog check is performed can also influence the cost. Different counties in California may have varying regulations and fees associated with smog checks. For example, some counties may require additional inspections or impose higher fees for certain types of vehicles.

It’s important to check with the local authorities or smog check facilities in your county to understand any additional costs or requirements specific to your area.

Failed Tests and Re-Inspections

If your vehicle fails its initial smog check, you may need to spend additional money on repairs and re-inspections. Failed tests often require specific repairs to bring the vehicle’s emissions within the acceptable range.

The cost of these repairs can vary depending on the extent of the issue and the parts needed. Additionally, some facilities may charge a re-inspection fee to verify that the necessary repairs have been made and the vehicle now passes the smog check.

It’s important to note that the specific costs associated with each of these factors can vary widely.

Finding Low Cost Smog Checks in California

Getting a smog check is a necessary requirement for vehicle owners in California. However, the cost of these checks can vary depending on several factors. To help you find the best deal, here are some tips to find low-cost smog checks in California.

Compare Prices Online

One of the easiest ways to find low-cost smog checks is by comparing prices online. There are several websites and platforms that allow you to enter your location and receive quotes from various smog check stations in your area.

By comparing prices, you can find the most affordable options without having to make multiple phone calls or visits.

Some popular websites that offer this service include Yelp and SmogTips. These platforms provide a comprehensive list of smog check stations along with their prices, customer reviews, and ratings. This allows you to make an informed decision based on both cost and quality of service.

Check for Coupons and Specials

Another way to save on smog checks is by checking for coupons and specials offered by smog check stations. Many stations offer discounts or promotional deals that can significantly reduce the cost of your smog check.

These coupons can often be found on the station’s website, local newspapers, or coupon websites.

Additionally, some smog check stations may offer specials during certain times of the year, such as holidays or off-peak seasons. Taking advantage of these promotions can help you get a lower price without compromising the quality of the service.

Visit Test-Only Centers

If you’re looking for the lowest cost option, consider visiting a test-only smog check center. These centers are dedicated solely to performing smog checks and do not offer repairs. As a result, their prices are often lower compared to stations that provide both smog checks and repairs.

Test-only centers are required to follow the same guidelines and standards as other smog check stations, so you can be confident in the accuracy and reliability of their tests. While these centers may not offer additional services, they can be a great option for those on a tight budget.

Remember, finding a low-cost smog check doesn’t mean compromising on quality. By comparing prices, checking for coupons and specials, and considering test-only centers, you can ensure that you’re getting a great deal without sacrificing the integrity of the smog check process.

When You Need to Get a Smog Inspection in California

In California, smog inspections are required for most vehicles during the registration process. The California Smog Check Program was implemented in order to reduce air pollution and improve the air quality in the state.

The program aims to ensure that vehicles meet certain emissions standards and are not contributing to excessive smog.

New Vehicle Registrations

In California, when you purchase a new vehicle model that is less than four years old, it is typically exempt from smog inspections for the first eight years. This is because new vehicles are subject to stricter emissions standards and are not expected to have any issues that would cause them to fail a smog check.

However, it’s important to note that this exemption only applies to the initial registration. Once the vehicle reaches its ninth year, it will be required to undergo smog inspections every two years.

Used Vehicle Registrations

If you are registering a used vehicle in California, you will generally be required to obtain a smog inspection. The specific requirements vary depending on the vehicle’s age, weight, and location. Most used vehicles are subject to biennial smog inspections, meaning they must be inspected every two years.

However, there are certain exceptions to this rule. For example, vehicles that are over 25 years old are generally exempt from smog inspections.

Change of Ownership

When you purchase a used vehicle in California, you will also be required to obtain a smog inspection if the vehicle’s previous registration occurred more than 90 days ago. This is known as a change of ownership smog check.

The purpose of this requirement is to ensure that the vehicle’s emissions are in compliance with state regulations, even if it has changed hands since its last inspection.

It’s important to note that these requirements may vary depending on the county you reside in. Some counties have additional smog check requirements that go beyond the state’s minimum standards.


While smog check requirements are mandatory for California drivers, costs can vary widely based on where you go and your vehicle’s age. With some savvy shopping and price comparisons, you can likely find inexpensive smog inspections in the $30-$50 range. Planning ahead and budgeting for this necessary auto expense will help California drivers renew their registration hassle-free.
