Legal Requirements & Notes

Auto repair shops are subject to a range of consumer protection and licensing regulations. Key legal considerations:

  • State Motor Vehicle Repair Acts: Most states have laws requiring auto repair shops to provide written estimates before beginning work, obtain customer authorization, provide itemized invoices, and return replaced parts on request. Examples: California's Automotive Repair Act (BAR), Illinois Motor Vehicle Service and Repair Act.
  • Written Estimates: Many states require a written estimate before starting repairs if the total cost exceeds a certain threshold (e.g., California requires a written estimate for any repair over $100). Ensure your customer has authorized the work in writing.
  • Returned Parts: Many state laws give customers the right to request return of replaced parts (except items returned under a core charge). Note on the invoice whether old parts were returned or disposed of.
  • Labor Rates: Post your labor rates prominently in the shop. Many states require disclosure of posted labor rates and that the invoice reflect those rates.
  • Warranty Disclosures: Written warranties on vehicle repairs must comply with the federal Magnuson-Moss Warranty Act if the warranty is offered on a consumer product repair. Ensure your warranty language is clear and not misleading.
  • Shop Supplies Fees: Some states require disclosure of shop supply fees before repairs begin. The fee should be reasonable and proportional.

    • Frequently Asked Questions

    In most states, yes. State motor vehicle repair laws typically require shops to provide a written estimate before beginning work and to get customer authorization — either in person, by phone (documented), or in writing. California, for example, requires written estimates for repairs over $100 under the Automotive Repair Act.
