For businesses entering the federal marketplace, identifying the correct North American Industry Classification System (NAICS) code is the foundational step in pursuing government opportunities. For general contractors, selecting the right code is not just a matter of classification—it determines your size status, eligibility for small business set-asides, and your ability to compete for specific solicitations.
Definition
The primary NAICS code for general contractor construction is 236220: Commercial and Institutional Building Construction. This code covers general contractors responsible for the construction of commercial, industrial, and institutional buildings.
While 236220 is the most common code for general building construction, the construction sector is vast. Other relevant codes include:
- 236115: New Single-Family Housing Construction
- 237110: Water and Sewer Line and Related Structures Construction
- 237310: Highway, Street, and Bridge Construction
Under 13 CFR Part 121, the Small Business Administration (SBA) assigns a size standard to each NAICS code. For 236220, the current small business size standard is $45 million in average annual receipts. If your firm exceeds this threshold, you are considered an "other than small" business for that specific procurement.
Examples
If a federal agency issues a solicitation for the renovation of an existing office building, they will almost certainly designate 236220 as the primary NAICS code.
- Scenario A: A small general contractor with $10 million in annual revenue bids on a $5 million renovation project. Because they fall under the $45 million threshold for 236220, they qualify as a small business for this set-aside.
- Scenario B: A firm specializes in electrical work but acts as the prime contractor for a building renovation. They must ensure their primary business activity aligns with 236220 to be considered a general contractor rather than a specialty trade contractor (e.g., 238210).
Using tools like SamSearch allows contractors to track which NAICS codes are being utilized by specific agencies, helping you identify where your firm’s capabilities align with federal demand.
Frequently Asked Questions
1. Can I have more than one NAICS code? Yes. While you must designate one primary NAICS code in your System for Award Management (SAM.gov) profile, you can list multiple secondary codes that represent your capabilities. Ensure these are accurate to avoid misrepresentation.
2. What happens if I choose the wrong NAICS code? Choosing the wrong code can lead to bid protests. If a competitor notices you have bid on a contract for which you do not meet the size standard or the functional description, they may challenge your eligibility, potentially resulting in your disqualification.
3. How often do NAICS size standards change? Size standards are reviewed periodically by the SBA. It is vital to check the latest SBA Table of Size Standards before submitting a proposal to ensure your status has not changed.
Conclusion
Navigating the complexities of NAICS codes is a critical skill for any successful government contractor. By understanding the nuances of 236220 and its related codes, you position your firm to compete effectively for construction contracts. Leveraging data-driven platforms like SamSearch ensures you stay informed on how these codes are being applied across the federal landscape, keeping your business compliant and competitive.
