Small Business Set-Aside Contracts: Complete Guide to Government Opportunities 2025

The federal government spends over $150 billion annually with small businesses, and construction represents a significant portion of that spending. Understanding set-aside programs and how to leverage them can dramatically increase your success in government contracting.

What Are Set-Aside Contracts?

Set-aside contracts are government procurements reserved exclusively for small businesses or specific small business categories. These programs level the playing field by limiting competition to qualified small contractors.

Types of Set-Asides

| Set-Aside Type | Abbreviation | Target Group | |----------------|--------------|--------------| | Small Business | SB | All small businesses | | 8(a) Business Development | 8(a) | Socially/economically disadvantaged | | HUBZone | HUBZone | Historically underutilized business zones | | Service-Disabled Veteran-Owned | SDVOSB | Service-disabled veteran owners | | Women-Owned Small Business | WOSB | Women-owned businesses | | Economically Disadvantaged WOSB | EDWOSB | Low-income women-owned |

Set-Aside Goals by Agency

Federal agencies must meet small business contracting goals:

  • Overall small business: 23% of prime contracts
  • Small disadvantaged business: 5%
  • Women-owned small business: 5%
  • Service-disabled veteran-owned: 3%
  • HUBZone small business: 3%

Small Business Size Standards for Construction

Size standards determine if your company qualifies as "small" for specific contract opportunities.

NAICS Code Size Standards

| NAICS Code | Industry | Size Standard | |------------|----------|---------------| | 236115 | New Single-Family Housing | $45 million | | 236116 | New Multifamily Housing | $45 million | | 236210 | Industrial Building Construction | $45 million | | 236220 | Commercial/Institutional Building | $45 million | | 237110 | Water/Sewer Line Construction | $45 million | | 237310 | Highway/Street Construction | $45 million | | 237990 | Other Heavy Construction | $45 million | | 238XXX | Specialty Trade Contractors | $19 million |

Size standards are based on average annual receipts over 5 years

Calculating Your Size

Your company's size is calculated by:

  1. Sum annual receipts for past 5 fiscal years
