NAICS 811111 – General Automotive Repair covers the maintenance, diagnostics, repair, and overhaul of light-duty and medium-duty motor vehicles, including passenger cars, trucks, vans, and specialized government fleet vehicles. This sector encompasses mechanical and body repair services such as engine tuning, brake system restoration, suspension alignment, electrical system diagnostics, and collision repair using OEM and aftermarket parts. In the federal contracting landscape, this NAICS supports mission-critical mobility for agency fleets, ensuring operational readiness across civilian, law enforcement, and military applications. Services are often delivered under indefinite-delivery/indefinite-quantity (IDIQ) contracts, blanket purchase agreements (BPAs), or task orders requiring compliance with federal vehicle maintenance standards and environmental regulations. Top contractors in this space include TECH O. R., LLC, EXTREME GOVERNMENT SOLUTIONS LLC, MIDWEST TRANSIT EQUIPMENT INC, BHPE LLC, and IMPERIAL AUTO BODY & SALES, a mix of small businesses and mid-sized firms with specialized expertise in fleet maintenance, mobile repair units, and government-compliant bodywork. These contractors typically hold small business set-asides or 8(a) certifications, reflecting a competitive environment where agility, local service networks, and compliance with federal vehicle maintenance protocols are key differentiators. Primary buyers include the Department of Defense, Department of Veterans Affairs, General Services Administration, Department of Agriculture, and Department of Homeland Security. These agencies rely on consistent vehicle uptime for logistics, emergency response, veteran transportation, and rural patrol operations, driving demand for preventive maintenance, fleet modernization, and rapid-response repair services. The market is characterized by high opportunity density across regional fleet hubs, with recurring procurement cycles tied to vehicle lifecycle management. Contractors with certified technicians, access to diagnostic tools compliant with federal specifications, and experience in managing multi-site maintenance contracts are best positioned to compete. Demand is increasingly driven by the need for fuel-efficient and low-emission fleet repairs, aligning with broader sustainability initiatives across federal agencies.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 811111 work as a small business.

$9.0M
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
