New Hampshire auto repair estimate rules

Source: N.H. Rev. Stat. Ann. (RSA) Chapter 358-D (Regulation of Motor Vehicle Repair Facilities)

New Hampshire's Motor Vehicle Repair Law applies to cars and small trucks but explicitly excludes motorcycles, motor-driven cycles, and large trucks. Upon customer request, a repair facility must provide a written estimate itemizing the work, estimated parts/labor price, and completion date. No service or repair work in the written estimate may begin without the customer's written permission - unless written permission is impracticable, in which case oral advice of the estimate contents and oral permission suffice. If additional, unrelated repair work becomes necessary, the facility must notify the customer of the estimated cost and get written or oral permission before proceeding. Upon completion, the facility may not charge more than 10% over the estimate without the customer's written consent. The facility is excused from a written completion-date promise (but not the price cap) for acts of God, strikes, unexpected illness, unexpected parts/labor shortage, or customer unavailability. A facility need not give an estimate if it declines to perform the work, but it cannot coerce a customer into waiving the estimate right as a condition of service.
