Maryland Auto Repair Law

Educational summary only – not legal advice.

Governing Law: Maryland Commercial Law Article, Title 14, Subtitle 10 (Automotive Repair Facilities)

This document translates Maryland’s auto repair statutes into plain‑English operational rules for consumers and repair shops.

1. Core Legal Rules at a Glance

·       Written estimate: Required upon customer request for repairs over $50.

·       Over‑estimate cap: Final bill may not exceed the estimate by more than 10% without customer consent.

·       Authorization: Repairs must be authorized in advance using a statutory authorization form.

·       Unauthorized repairs: Cannot be charged unless the customer approves them.

·       Replaced parts: Customers are entitled to replaced parts, unless warranty return is required.

·       Record retention: No statewide minimum retention period specified.

2. Dollar Thresholds & Estimates

·       Shops must provide a written estimate if requested by the customer before beginning work costing more than $50.

·       Shops may charge a reasonable fee for preparing an estimate only if the fee is disclosed before the estimate is prepared.

If state law is silent: Maryland law does not require written estimates for repairs under $50 unless local ordinances apply.

3. Authorization Form Requirements

Before work begins, repair shops must provide an authorization form that clearly discloses, under a separate heading titled “Customer’s Rights”:

·       The right to request a written estimate for repairs over $50;

·       The 10% limit on charges over the estimate without consent;

·       The right to receive replaced parts;

·       The right not to be charged for unauthorized repairs.

If the vehicle is left after hours or towed in, these rights may be given orally but must be documented in writing.

4. Over‑Estimate Approval Rules

·       Shops may not exceed the estimate by more than 10% without customer approval.

·       Customer consent must be obtained before additional work is performed.

If state law is silent: Maryland law does not specify whether approval must be written or oral; general contract and consumer protection principles apply.

5. Disclosure Timing

·       Estimates and authorization disclosures must occur before repairs begin.

·       Final invoices must itemize labor, parts, surcharges, and required liability disclosures.

6. Replaced Parts Rules

·       Customers are entitled to receive replaced parts automatically.

·       Exception: Parts required to be returned to a manufacturer under warranty.

If state law is silent: Maryland law does not specify how long shops must retain parts if a customer delays pickup.

7. Record Retention

If state law is silent: Maryland does not establish a statewide minimum record‑retention period for repair orders or invoices. General business and tax laws apply, and local jurisdictions may impose stricter requirements.

8. Enforcement & Consequences

·       Customers may bring civil actions for violations.

·       Overcharges and unauthorized repairs may be legally unenforceable.

·       Complaints may be filed with the Maryland Attorney General’s Consumer Protection Division.

·       Violations may also trigger liability under Maryland’s Consumer Protection Act.

What This Means for Consumers

·       You control repair costs through the estimate and authorization process.

·       You cannot legally be surprised with major overcharges.

·       You have a right to transparency, consent, and accountability.

·       Violations give you leverage: disputes, complaints, or lawsuits.

What This Means for Repair Shops

·       Always offer estimates and document customer requests.

·       Never exceed an estimate by more than 10% without approval.

·       Use compliant authorization forms with required disclosures.

·       Document all customer communications.

·       Implement internal policies for estimates, approvals, invoices, and recordkeeping.

Bottom line: If you run a shop or hire one in Maryland, cost control, advance authorization, and documentation are the core legal pillars. Follow them, and disputes largely disappear.
