Maryland caps what a repair shop can add to a written estimate at ten percent without your consent, which is a real protection. The catch is that the estimate is not automatic. State law gives you the written statement on request, for work costing more than fifty dollars, so the cap only switches on for drivers who know to ask for it before any wrench turns. Most people never do.
Maryland Commercial Law § 14-1002 says that before beginning repair work for which a customer is charged more than fifty dollars, an automotive repair facility shall give the customer, on the customer’s request, a written statement containing the estimated completion date, the estimated price for labor and parts, a statement about the facility’s responsibility for damage while the vehicle is on the premises, and any estimated surcharge. Subsection (b) then provides that the facility may not charge any amount exceeding the written estimate by ten percent without the customer’s consent.
Read those two together and the sequence matters. No request, no written estimate. No written estimate, no ten percent ceiling. A shop may charge a reasonable fee for producing the estimate if that fee is disclosed to you beforehand.
Section 14-1008 requires the facility to give you an authorization form before starting, setting out your rights conspicuously under the heading Customer’s Rights, physically separated and immediately above the signature line. Those rights include the right to request the written estimate on work over fifty dollars, the ten percent limit, the right to have replaced parts returned, and protection against charges for unauthorized repairs. Oral authorization is allowed where the vehicle is towed in or dropped after hours, but the notice has to be documented in writing.
Elsewhere in the same subtitle, Maryland requires an itemized invoice and the return of replaced parts, and gives the customer a civil action for violations.
The Maryland rules give you a script for the counter. Use it at drop-off, when the shop still wants the work, rather than at pickup when the leverage has gone.
This page is general information, not legal advice. The Maryland sections cited above come from a recent code edition rather than a certified current text, and repair statutes are amended from session to session, so confirm with the Maryland Attorney General’s Consumer Protection Division before relying on them.
On request, and for work costing more than fifty dollars. Maryland Commercial Law Section 14-1002 requires the facility to give the customer a written statement on the customer's request, covering the estimated completion date, the estimated price for parts and labor, a statement about responsibility for damage on the premises, and any estimated surcharge. If you do not ask, the shop is not obliged to produce one.
Not by more than ten percent without your consent. Section 14-1002(b) provides that an automotive repair facility may not charge a customer, without consent, any amount which exceeds the written estimate by ten percent. That ceiling depends on there being a written estimate in the first place, which is why the request at drop-off matters.
Section 14-1008 requires the facility to give an authorization form before beginning repairs, with the customer's rights set out conspicuously under that heading, physically separated and immediately above the signature line. It covers the right to request a written estimate over fifty dollars, the ten percent limit, the right to have replaced parts returned, and protection against charges for unauthorized repairs.
Yes, the subtitle provides for replaced parts to be returned to the customer, and it is one of the rights the authorization form must disclose. Ask at drop-off rather than at collection, because some parts go back to a supplier as cores and are gone by the time the bill is written.
