The General Services Administration dominates this market, with its Public Buildings Service Portfolio Manager, Public Buildings Service, and various leasing divisions accounting for the vast majority of federal real estate leasing activity. GSA buys space for federal agencies across the country through multiple contracting vehicles and regional offices. Most awards carry no set-aside designation, meaning they are open to all qualified vendors. Small Business Administration set-asides are rare in this category, with only 1,072 awards recorded across the entire period.

Awards in this space tend to be small. The median award sits at $12,000, though the total pool of $29.55B spread across 612,451 awards shows that volume matters more than individual contract size. With 6,536 distinct vendors on record, the market supports many participants, but competition is substantial. A firm considering entry should expect to compete frequently for modest-sized leases rather than pursue large, singular opportunities.

The pipeline shows moderate activity ahead. There are 154 active notices currently posted and 245 contracts expiring within the next 12 months worth $170.61M in total value. This turnover creates regular opportunities for new vendors to enter existing relationships or for current lessors to renew. Firms should monitor GSA's leasing divisions closely, particularly the regional offices, since they issue the highest volume of awards.

The numbers above come from awards and notices carrying this exact code. Related work often sits in the neighboring codes listed below, so watch the neighbors too.

The official definition, with what the code includes and excludes, is on the Census NAICS page linked at the bottom.
