NAICS 531320 — Offices of Real Estate Appraisers encompasses professional services related to the valuation of real property for federal purposes, including residential, commercial, and government-owned assets. Appraisers in this sector conduct independent, objective analyses using standardized methodologies such as the Uniform Standards of Professional Appraisal Practice (USPAP), often supporting acquisition, disposal, lease negotiations, and asset management decisions. These services are critical to ensuring fair market value determinations in compliance with federal procurement and financial accountability standards. The work is typically performed by licensed or certified appraisers who deliver detailed appraisal reports used in land acquisition for infrastructure projects, environmental remediation, military base realignment, and surplus property disposition. No contractor data is available for this NAICS code, indicating that no single firm or group of firms dominates federal award activity in this category. Contractors operating in this space are typically small to mid-sized appraisal firms, independent licensed appraisers, or specialized consulting practices that may also serve state and local governments or private clients. The competitive landscape is fragmented, with many providers operating regionally and relying on professional credentials rather than large-scale corporate infrastructure. No agency data is available, but demand is likely driven by agencies with significant real property portfolios, including the General Services Administration, Department of Defense, Department of Veterans Affairs, and the Department of the Interior. These agencies require appraisals for base realignment and closure (BRAC) initiatives, land acquisitions for national parks or defense installations, and disposal of surplus federal assets. The market is characterized by low entry barriers for qualified individuals but high regulatory and ethical standards. Opportunities exist for appraisers with expertise in federal compliance, environmental impact assessments, and complex property types such as contaminated sites or historic structures. Contracting is often project-based, with limited recurring spend, making long-term relationships and credentialing critical for sustained engagement.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 531320 work as a small business.

$9.5M
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.
