Competing in this code
208 IDVs against 1,337 actions at an average around $241,000 describes multi-year fleet maintenance agreements rather than individual repairs. The $9 million size standard is among the lowest anywhere in federal contracting, which means set-asides in this code reach independent shops, not regional chains. The realistic path is a single installation or facility fleet: a shop within reasonable distance, with technicians who can be vetted for base access and capacity to hold vehicles overnight, competes against a handful of others. GSA fleet work is the alternative lane and follows commercial terms much more closely.
Frequently Asked
NAICS 811111 questions, answered.
What is the SBA size standard for NAICS 811111?
SBA sets it at $9 million in average annual receipts, averaged over your last five completed fiscal years. Come in at or under that and you are small on every NAICS 811111 solicitation, including the set-asides.
Which agencies buy automotive repair under NAICS 811111?
FY2025 obligations: DoD ($287 million), USDA ($9 million), DOJ ($8 million), DHS ($8 million), GSA ($5 million). DoD at 89 percent is non-tactical fleet maintenance at installations, and GSA's share supports the governmentwide federal fleet program.
Why is the size standard so low in NAICS 811111?
SBA sets it at $9 million in average annual receipts, reflecting the scale of the independent repair industry. The practical effect is that a regional chain is too large to bid the set-asides in this code, which is unusual and makes it one of the more realistic first federal contracts for a local business.
What does a shop need to service a DoD installation fleet?
Technicians who can be vetted for base access, capacity to hold government vehicles overnight, and the ability to hold labor rates across multi-year option periods. Proximity matters because vehicles have to be moved. DoD obligated $287 million in the code in FY2025, and most of it runs as recurring facility-level agreements.
