Industry Definition & Overview
All Other Automotive Repair and Maintenance (NAICS 811198) encompasses establishments primarily engaged in providing automotive repair and maintenance services not classified elsewhere per the U.S. Census Bureau[5]. Activities include automotive detailing, window tinting, rustproofing and undercoating, upholstery repair, convertible top repair and replacement, truck accessory installation, spray-on bed liner application, and other specialized automotive services.
Automotive detailing has emerged as the largest segment within this classification, with mobile detailing services and fixed-location detail shops serving both retail and commercial fleet customers. Ceramic coating and paint protection film (PPF) application represents a premium service tier growing in popularity as vehicle owners invest in long-term appearance preservation. Window tinting shops serve both cosmetic and functional markets, with state regulations limiting visible light transmission percentages on different window positions. Truck accessory shops install aftermarket equipment including tool boxes, running boards, tonneau covers, and lift kits for pickup truck owners. The classification captures a diverse range of niche automotive services not large enough to merit individual NAICS codes.
Per the SBA Table of Size Standards[6], the size standard is $9 million in average annual receipts. State regulations govern window tinting darkness limits, with EPA[7] regulations applying to spray-on coating products containing volatile organic compounds (VOCs). OSHA[8] general industry standards address chemical exposure from detailing products, coatings, and adhesives used in aftermarket installation work.
