Auto Repair Shop Insurance Cost: Ranges + Calculator
A repair shop's defining exposure is other people's cars: garagekeepers legal liability covers customers' vehicles in your care, custody and control — on the lift, in the lot, on a test drive — and garage liability carries the premises and operations risk around them. Add workers' compensation for the techs and property coverage for the bays and equipment. (Collision and paint work is its own trade — see auto body shop insurance for the body-shop side.)
As an industry-typical estimate, a small mechanical shop commonly runs roughly $3,000–$8,000+/year across garage liability and garagekeepers, with workers' comp added on payroll. No insurance bureau publishes repair-shop premiums, so every dollar here is an estimate; each coverage fact is sourced to a named authority (IRMI, III, NCCI, OSHA).
