NAICS 531120 – Lessors of Nonresidential Buildings (except Miniwarehouses) encompasses the leasing of commercial, industrial, and institutional real estate properties to federal agencies for operational use. This includes office spaces, research facilities, data centers, warehouses, and other non-residential structures that support mission-critical activities. Unlike property management or construction services, this NAICS focuses exclusively on the rental of existing, owned buildings, where contractors act as property owners or intermediaries providing leased space under long-term agreements. In the federal contracting landscape, this sector enables agencies to acquire flexible, turnkey facility solutions without capital investment, often supporting logistics, administrative, and technical operations in remote or specialized locations. Top contractors in this space include ROCKWELL AMERICAN SERVICES, LTD., STORM SERVICES, LLC, PERFECTED SOLUTIONS LLC, AVENUE CONTRACT SOLUTIONS, LLC, and INFINITY TECHNOLOGY SERVICES LLC. These firms range from small businesses with niche property portfolios to mid-sized primes with diversified real estate holdings, often leveraging GSA schedules or direct lease agreements to secure federal tenancy. The competitive landscape is characterized by asset-heavy operators with strong local market presence and expertise in federal compliance, environmental standards, and facility maintenance requirements. The Department of Agriculture, Department of the Interior, and Department of Defense are the primary procuring agencies, seeking leased facilities to support field operations, ranger stations, research outposts, logistics hubs, and auxiliary command centers. Demand is driven by mission expansion, infrastructure modernization, and the need for geographically dispersed, secure, and sustainably maintained workspaces. The market offers consistent opportunity density for property owners and real estate investors with compliant, federal-ready buildings, particularly in rural, coastal, or defense-corridor regions. Procurement trends favor long-term leases with performance-based maintenance clauses, creating a stable revenue stream for contractors who can demonstrate regulatory adherence and operational reliability.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 531120 work as a small business.

$34.0M
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.
