NAICS 321991 – Manufactured Home (Mobile Home) Manufacturing covers the production of factory-built, transportable residential units designed for permanent or semi-permanent occupancy, typically installed on permanent foundations and connected to utilities. These homes are constructed in controlled environments to meet federal standards such as the HUD Code, ensuring structural integrity, fire safety, and energy efficiency. In the government contracting landscape, this NAICS supports housing programs for federal employees, military personnel, veterans, and tribal communities, particularly in remote or underserved locations where traditional construction is cost-prohibitive or logistically challenging. Products in this category include single-wide and double-wide units, modular housing systems, and accessory dwelling units configured for federal use. No contractor data is available for this NAICS code, indicating limited visibility of prime contractors or subcontractors actively competing for federal awards in manufactured home manufacturing. The competitive landscape appears fragmented, with potential participation from small businesses, tribal enterprises, and specialized manufacturers focused on government-compliant housing solutions. No agency data is available, suggesting that procurement activity in this sector is either infrequent, highly localized, or bundled under broader housing or infrastructure contracts rather than being tracked as a distinct line item. Potential demand drivers may include the Department of Housing and Urban Development, Department of Defense family housing initiatives, and tribal housing programs under the Indian Housing Block Grant. The market context reflects low opportunity density for contractors due to the specialized nature of the product and limited direct federal procurement. Opportunities may exist through indirect channels such as construction management firms, housing authorities, or grant-funded programs that specify manufactured housing as a solution. Trends suggest growing interest in rapid deployment housing for disaster relief and workforce housing, though federal contracting remains sparse and often tied to broader community development initiatives.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 321991 work as a small business.
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.
