Tony has run his shop on Lorain Avenue, Cleveland, for thirteen years. Two bays, three full-time techs, the standard mix of West Side neighborhood customers — Hondas, Subarus, the occasional Ford F-150 from a contractor in Lakewood. Tony does not have an Ohio state license to display because Ohio does not license auto repair shops at the state level. What Tony has is the obligation, under Ohio Revised Code §1345.05 (Attorney General consumer protection enforcement) and the implementing regulation OAC §109:4-3-13 (Motor vehicle repairs or services), to follow specific disclosure procedures on every repair where the cost is expected to exceed $50.

Ohio's framework is unusual in two ways. First, the regulatory threshold is $50 — one of the lowest in the country, on par with Connecticut and Wisconsin. Second, the regulation is structured around a three-option choice for the consumer: the consumer can choose to receive a written estimate, an oral estimate, or no estimate. The shop's obligation is to present the choice and document the consumer's selection. The shop cannot perform work above $50 without obtaining the consumer's choice on the record.

What OAC §109:4-3-13 actually requires

The Ohio Administrative Code rule on motor vehicle repairs has been in effect, in some form, since the 1970s and was last substantially revised in the early 2000s. The current version requires the shop, before performing or arranging to perform any repair or service that will cost the consumer more than $50, to:

  • Obtain a signed acknowledgment from the consumer in which the consumer chooses one of three options:
    1. The consumer requests a written estimate before any work is performed.
    2. The consumer authorizes the work without an estimate, provided the cost will not exceed a specified maximum dollar amount.
    3. The consumer waives the estimate entirely.
  • Provide the written estimate if the consumer chose option (a). Itemized parts (with new/rebuilt/used designation), parts unit prices, labor hours, hourly rate, total estimated cost.
  • Obtain additional consumer authorization if the actual cost will exceed the estimated cost (or the maximum dollar amount under option b) by more than 10%. The additional authorization is documented.
  • Provide an itemized invoice on completion. Parts (with new/rebuilt/used designation), labor by job and rate, total. The invoice must enable the consumer to verify what was done and what was charged for it.
  • Disclose the use of any non-OEM aftermarket parts (per ORC §1345.81 for insurance-paid repair estimates; the regulation extends the disclosure principle to direct customer-pay repairs as well).

The mechanism that bites is the signed three-option acknowledgment. Most Ohio shops do not present the three options. Most Ohio shops either provide a written estimate (effectively pre-selecting option a for the consumer) or skip the documentation entirely on lower-cost jobs. Both approaches are formally non-compliant with §109:4-3-13. The consumer cannot meaningfully waive the right to choose by silence.

What the Ohio AG inquiry looks like

The Ohio Attorney General's Office runs an active consumer-protection enforcement program under ORC §1345.05. The Attorney General has authority to: investigate consumer complaints, issue subpoenas, file formal enforcement actions in the Court of Common Pleas, and seek civil penalties of up to $25,000 per violation for "knowing" violations of the Consumer Sales Practices Act (ORC Chapter 1345).

The path from a single consumer complaint to an AG inquiry letter is short. A consumer files a complaint with the Ohio AG's Consumer Protection Section. The Section reviews. If the complaint suggests a pattern of conduct (rather than an isolated dispute), the Section opens an investigation. The investigation begins with an inquiry letter to the shop requesting documentation: estimates, work orders, invoices, the §109:4-3-13 three-option acknowledgments for the prior twelve months.

Tony receives such a letter in March 2026. The letter cites a specific consumer complaint involving a $470 brake-and-suspension job from January 2026. The complaint alleges that Tony's shop did not present the three options before performing the work, did not provide a written estimate, and did not obtain documented additional-work authorization for the $90 in additional bushings that were added to the job. The AG's Consumer Protection Section requests Tony produce: (1) the signed three-option acknowledgment for the disputed transaction, (2) the written estimate (if any), (3) the additional-work authorization documentation, (4) all signed three-option acknowledgments for the prior twelve months as a sample of the shop's compliance practice.

Tony does not have any signed three-option acknowledgments. Not for the disputed transaction. Not for any transaction. Tony's shop has never used the form because Tony did not know the form was required. The AG's Section now has documentary evidence of a pattern of non-compliance across approximately 800 jobs over twelve months.

What the AG offers Tony

The AG's Section offers an Assurance of Voluntary Compliance under ORC §1345.06. Tony agrees to: implement the §109:4-3-13 three-option acknowledgment form on every customer transaction above $50, provide written estimates when chosen, document additional-work authorization, retain records for at least three years, refund $90 to the disputed-transaction customer, and pay a civil penalty of $4,500.

The AVC is filed with the Ohio AG and is publicly searchable on the AG's enforcement-actions page. Tony's shop name appears in the search results when consumers Google the business name. The AVC includes a five-year monitoring provision during which any additional documented violation triggers a much steeper penalty, potentially including AG-filed civil action with the $25,000 per violation cap.

Total cost to Tony: $4,500 civil penalty + $90 refund + the cost of his attorney + the implementation cost of the new procedures. Approximately $7,500-$9,000 in direct costs, plus five years of monitoring, plus the public AG-listing reputational tail.

The five lines every Ohio auto repair invoice — and intake form — should include

1. The §109:4-3-13 three-option acknowledgment, signed by the customer at intake

Required by Ohio Administrative Code §109:4-3-13 for any work above $50. The form presents the three options (written estimate / oral estimate with maximum / no estimate) and obtains the consumer's signature. The form is the single most important compliance document for an Ohio repair shop. Without it, the entire transaction is procedurally non-compliant regardless of the underlying repair quality.

2. Written estimate (if option a chosen) — itemized parts and labor with customer signature

Itemized parts (with new/rebuilt/used designation), parts unit prices, labor hours, hourly rate, total estimated cost, customer signature with date.

3. Documented additional-work authorization above 10% (or above the maximum if option b)

Date, time, name of the person consenting, additional dollar amount, brief description. Documented in the customer file.

4. Itemized invoice on completion with parts designations

Each part listed individually with new/rebuilt/used designation, unit price, labor itemized by job (hours and hourly rate), parts subtotal, labor subtotal, applicable Ohio sales tax (parts are generally taxable; labor on parts is treated as part of the taxable transaction in Ohio for repair services), total.

5. Non-OEM aftermarket parts disclosure (ORC §1345.81 + best practice)

Required for insurance-paid estimates by ORC §1345.81. Best practice for direct-customer-pay repairs. The disclosure identifies any non-OEM aftermarket parts being installed and obtains the customer's signed acknowledgment.

The Cleveland customer's complaint reaches the AG within thirty days

Ohio's AG Consumer Protection Section is well-staffed and aggressive. Complaints from consumers in Cleveland, Columbus, Cincinnati, Toledo, and Akron are routed to the Section within days of submission. Pattern-of-conduct cases — where the consumer's individual dispute reveals a broader compliance gap — are prioritized for investigation. The path from "single customer files a complaint" to "AG inquiry letter requesting twelve months of documentation" can take as little as sixty days.

Mekavo automatically prints the §109:4-3-13 three-option acknowledgment as the intake form for every customer over the $50 threshold, prints the written estimate template (if option a is chosen) with itemized parts and customer signature, prints the additional-work authorization log, prints the §109:4-3-13-compliant itemized invoice with parts designations, and supports the non-OEM disclosure for insurance-paid repairs. When the AG inquiry letter arrives, the documentation already exists for every job in the prior twelve months.
