Automotive Repair — Colorado Motor Vehicle Repair Act (conduct rules)

Colorado regulates repair garages by conduct under the Motor Vehicle Repair Act, C.R.S. 42-9-101 to 42-9-113, and the Attorney General's resource guide directs consumers to report violations to their district attorney's office. As the guide describes it, a garage must obtain the customer's written consent before repairs, must give a written or oral estimate of all costs, and may not collect more than the estimate plus ten per cent or twenty-five dollars, whichever is less, without the customer's consent. The revenue department's Auto Industry Division fee schedule for July 2026 to June 2027 (form DR 2246) lists dealer, powersports dealer, wholesaler, business disposal, buyer agent, wholesale auction, salesperson, manufacturer, distributor and manufacturer representative licenses and contains no repair facility category, and the regulatory agencies department's licensing page lists no repair trade. A shop still needs a sales tax license for parts and whatever its city requires.
