Business Overview


This business is needed because of the large demand for vehicle customization. Since all jobs are customized or fabricated on-site, the complexity of each job varies with the customer and request. The market for this business consists mostly of automotive enthusiasts.

Who is this business right for?

Custom car shops appeal to entrepreneurs who are automotive enthusiasts and love engineering and designing. As a custom car shop owner, you need to be willing to work long hours, manage a team of technicians, and love working with your hands. You also need to have a passion for the automotive enthusiast community, which tends to have its own unique culture apart from the general population.

What happens during a typical day at a custom car shop?

Custom car shops appeal to entrepreneurs who are automotive enthusiasts and love engineering and designing. As a custom car shop owner, you need to be willing to work long hours, manage a team of technicians, and love working with your hands. You also need to have a passion for the automotive enthusiast community, which tends to have its own unique culture apart from the general population.

If you have a team of mechanics, you also need to manage your crew. If your mechanics are on a flat rate flag system, you must set up jobs for them throughout the day.

What is the target market?

Custom vehicles appeal to the automotive enthusiast crowd, which is a subset of the general population. Most jobs are sold retail to customers. Some shops, however, do work with corporation or governments, offering fleet work for these organizations.

How does a custom car shop make money?

This business depends on consumers coming into the shop, requesting custom work on their vehicle. The shop is paid a fee for this service. Generally, the fees are variable and depend on the job being performed. Some fees are flat or fixed-rate, while others are variable and billed by the hour.

Customers pay the shop and the shop pays the mechanic for the work performed.

What is the growth potential for a custom car shop?

It is difficult to run a custom car shop out of a small location. Usually, a large warehouse (40’ x 80’-100’) with at least 8 service bays is required. This is because at least one bay will be needed for a paint booth, while two more are needed at prepping and staging areas for the mechanics to prepare a vehicle for paint (if you offer these services).

The remaining bays are for non-body work and maintenance work.

However, some custom shops do specialize in certain kinds of customizations (e.g. custom stereo installation). These shops can be run out of a large garage.

Custom car shops can expand to service more customers, even opening multiple locations should demand exceed the capabilities of the first shop.

Getting Started


What are some skills and experiences that will help you build a successful custom car shop?

ASE certifications are great to have for a business like this because it shows professionalism. However, you’ll also need extensive experience and training in the specific types of customizations your shop will perform.

Opening a custom car shop requires familiarity with building and rebuilding, repairing vehicles, and experience with customizing various makes and models. This experience is best developed working for an existing successful custom car shop. Customization of automobiles is also driven by trends. So, you need to keep your finger on the pulse of the market and follow the current trends.

It’s also important to pay attention to regulations, since modifications must comply with local, state, and federal law. Some customizations, like window tints, may be restricted or illegal and exhaust pipes need to comply with EPA regulations.

What are the costs involved in opening a custom car shop?

Costs for starting a custom car shop vary and generally depend on location. However, basic costs include:

  • Air compressor - range from $100 used to $2,000 new
  • Refrigerated evaporating system - $1,500 to $3,500
  • Jitter bugs, dual-action sanders - $200
  • Sanding blocks - $0.50 to $1 each
  • Masks and paint suits - $250
  • Cabinet (for solvents, paints, and cleaners) - $80 to $2,500
  • HVLP guns of different sizes - $500 to $1,000 each
  • Lift - $1,500 to $3,000 each (you will need between 3 and 5 of these)
  • Air tools (like impact, air nozzle, etc) - $60 to $200 each
  • Tools to stock boxes - $150 for basic 50 to 100-piece mechanic’s tool set; $40,000 for a 1,390-piece comprehensive set
  • Parts washer - $100 to $200
  • Diagnostic machine - $3,000 to $4,000
  • Rebuilding counters - $400
  • Woodworking tools - $200 for a basic set
  • Fiberglass tools - $100 for a basic set
  • Electrical tools for stereo and complete body wiring - $150 to $300

These are basic costs. Total costs may be higher, depending on the specific needs of your business.

What are the steps to start a custom car shop?

Once you're ready to start your custom car shop, follow these steps to ensure that your business is legally compliant and avoid wasting time and money as your business grows:

  1. Plan your business. A clear plan is essential for success as an entrepreneur. A few important topics to consider are your initial costs, your target market, and how long it will take you to break even.
  2. Form a legal entity. Establishing a legal business entity prevents you from being personally liable if your custom car shop is sued.
  3. Register for taxes. You will need to register for a variety of state and federal taxes before you can open for business.
  4. Open a business bank account. A dedicated checking account for your custom car shop keeps your finances organized and makes your business appear more professional to your customers.
  5. Set up business accounting. Recording your various expenses and sources of income is critical to understanding the financial performance of your business. Keeping accurate and detailed accounts also greatly simplifies your annual tax filing.
  6. Obtain necessary permits and licenses. Failure to acquire necessary permits and licenses can result in hefty fines, or even cause your business to be shut down.
  7. Get business insurance. Insurance is highly recommended for all business owners. If you hire employees, workers compensation insurance may be a legal requirement in your state.
  8. Define your brand. Your brand is what your company stands for, as well as how your business is perceived by the public. A strong brand will help your business stand out from competitors.
  9. Establish a web presence. A business website allows customers to learn more about your company and the products or services you offer. You can also use social media to attract new clients or customers.

What are some insider tips for jump starting a custom car shop?

Growing Your Business


How to promote & market a custom car shop

This type of business is heavily dependent on referrals. Most custom shops cater to automotive enthusiasts in a local community. Flyers and local ads may help but, ultimately, good service and quality work will help spread the word.

Recommended: Get started with local advertising for your business with a $300 credit from Yelp.

How to keep customers coming back

The most successful shops specialize in a market. For example, your shop might specialize in custom audio installations. You may not be able to do all types of audio installations when you first start out, but you could build out this specialty.

Other specialties include:

  • Wheel shop
  • Paint shop
  • Custom interiors
  • Custom alarms

How and when to build a team

While some shop owners are “one man shops,” this is a difficult business to do alone. Consider hiring a crew immediately. At minimum, you will want one mechanic to take over day-to-day service so you can run the shop and perform all managerial duties.

Legal Considerations


State & Local Business Licensing Requirements

Certain state permits and licenses may be needed to operate a custom car shop. Learn more about licensing requirements in your state by visiting SBA’s reference to state licenses and permits.

Most businesses are required to collect sales tax on the goods or services they provide. To learn more about how sales tax will affect your business, check out our informative guide, Sales Tax for Small Businesses.

In addition, certain local licensing or regulatory requirements may apply. For more information about local licenses and permits:

Services Contract

Custom car businesses should require clients to sign a services agreement before starting a new project. This agreement should clarify client expectations and minimize risk of legal disputes by setting out payment terms and conditions, and service level expectations. Here is a resource explaining the necessity of a “pre-build contract.”

Recommended: Rocket Lawyer makes it easy to create a professional service agreement for your custom car business when you sign up for their premium membership. For $39.95 per month, members receive access to hundreds of legal agreements and on call attorneys to get complimentary legal advice.

Labor safety requirements

It is important to comply with all Occupational Safety and Health Administration requirements:

Many of the regulations for custom car shops are general. Employers must take steps to create a safe working environment and report employee injuries.

Certificate of Occupancy

A custom car shop is generally run out of a warehouse. Businesses operating out of a physical location typically require a Certificate of Occupancy (CO). A CO confirms that all building codes, zoning laws and government regulations have been met.

  • If you plan to lease a location:
    • It is generally the landlord’s responsibility to obtain a CO.
    • Before leasing, confirm that your landlord has or can obtain a valid CO that is applicable to a custom car shop.
    • After a major renovation, a new CO often needs to be issued. If your place of business will be renovated before opening, it is recommended to include language in your lease agreement stating that lease payments will not commence until a valid CO is issued.
  • If you plan to purchase or build a location:
    • You will be responsible for obtaining a valid CO from a local government authority.
    • Review all building codes and zoning requirements for your business’ location to ensure your custom car shop will be in compliance and able to obtain a CO.

Car Modifications

Certain car modifications may be unlawful, depending on the regulations in each state. Here is a resource addressing the legality of certain modifications by state.

Reduce Personal Liability

Structuring your business as a limited liability company (LLC) ensures your personal assets are protected in the event your business is sued.

  • Rent - $1,500 to $15,000 per month, depending on location
  • Insurance - $4,000 per year
  • Labor - $20,000 to $45,000 per year, per employee

How much profit can a custom car shop make?

Shop owners typically make an average income of between $50,000 and $100,000 per year. The shop itself may bring in several hundred thousand or a million dollars in revenue.

How can you make your business more profitable?

Custom car shops can make more money by branching out and offering basic maintenance. In today’s economy, the market for customization is smaller than it was just 10 years ago. However, costs for customization have risen. This means work may bring in good revenue, but jobs may be sparse. Filling in with routine maintenance can help boost revenue.
