NAICS 531190 – Lessors of Other Real Estate Property encompasses the leasing of real estate assets that are not classified as residential or commercial buildings, including land, specialized facilities, and non-standard properties such as storage yards, research plots, remote monitoring sites, and undeveloped parcels used for government operations. This sector supports mission-critical infrastructure needs by providing temporary or long-term access to property that enables logistical, environmental, scientific, or defense-related activities.

NAICS 531190 – Lessors of Other Real Estate Property encompasses the leasing of real estate assets that are not classified as residential or commercial buildings, including land, specialized facilities, and non-standard properties such as storage yards, research plots, remote monitoring sites, and undeveloped parcels used for government operations. This sector supports mission-critical infrastructure needs by providing temporary or long-term access to property that enables logistical, environmental, scientific, or defense-related activities. Unlike traditional real estate leasing, contracts under this code often involve unique use cases like military training grounds, satellite ground station sites, or conservation easements, requiring compliance with federal land use regulations and environmental stewardship standards. These arrangements are typically structured as lease-purchase agreements, easements, or right-of-way grants, and are integral to agencies requiring spatial flexibility without direct ownership. No contractor data is available for this NAICS code, indicating a fragmented or highly specialized contractor base, potentially composed of small businesses, land trusts, or regional property holders rather than large primes. The competitive landscape is likely dominated by local or niche entities with direct control over unique real estate assets, making relationship-building and site-specific compliance critical for market entry. No agency data is available, though demand is likely driven by agencies such as the Department of Defense, U.S. Forest Service, Bureau of Land Management, and the National Park Service, which require access to non-traditional land for training, research, or conservation missions. Spending patterns may be tied to long-term land use planning, environmental mitigation, or infrastructure expansion efforts. The market is characterized by low transaction volume but high strategic value, with opportunities concentrated in regions with expansive federal land holdings. Contractors with expertise in federal land law, environmental permitting, and lease administration are best positioned to compete. Procurement tends to be project-specific and non-competitive, often awarded through sole-source or limited-bid processes due to the unique nature of the assets involved.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 531190 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.
