About the company
United Site Services Of California Inc., doing business as United Site Services, is a Massachusetts-based for-profit portable sanitation and temporary facilities provider that operates as a subsidiary of United Site Services, Inc. and competes as a prime contractor (97% of recent awards) in full-and-open federal procurements without set-aside designations. The vendor supplies portable toilets, restroom trailers, shower trailers, holding tanks, septic tank services, and handwashing stations to federal agencies across defense, civilian, and civilian-emergency response missions, with work performed at locations spanning California to Massachusetts and subordinate operational sites nationwide.
United Site Services Of California Inc. draws customer concentration heavily from the U.S. Forest Service Pacific Southwest Region, which accounts for 73% of recent award volume and 80% of combined potential value across the portfolio. The Forest Service R5 region (28 awards, $1.2 million combined potential value) is the dominant customer by both metrics, anchoring the vendor's footprint with portable toilet rentals supporting firefighting operations, recreation area management, and emergency incident response. The Department of the Interior National Park Service Pacific West Region ($463 thousand across 3 awards), the Department of the Army Corps of Engineers Sacramento District ($450 thousand, 1 award), and the Department of Health and Human Services Administration for Children and Families ($420 thousand, 1 award) round out the top-value customers. Secondary customers include the Department of Veterans Affairs Veterans Integrated Service Network 22 (4 awards, $347 thousand), the Department of Homeland Security Coast Guard (5 awards, $26 thousand), and the Defense Logistics Agency Distribution (4 awards, $122 thousand). Recent prime awards include a $180 thousand portable toilet rental with Forest Service R5 for the Caldor emergency response (awarded September 2021), a $54 thousand portable toilet rental contract with Naval Education and Training Command at Naval Base San Diego running through August 2029 (awarded February 2024), and a $23 thousand restroom trailer procurement from the Department of Defense (awarded April 2025).
Activity has declined over the five-year window — seven awards in 2021 down to two in 2025 — with annual award volume trending toward lower frequencies in recent years. The vendor also holds one subcontract award (2% of portfolio) as a temporary fencing sub to Korte Construction Company on a General Services Administration Vandenberg Space Force Base consolidated maintenance facility project, with a modification adding $631 thousand to the contract value (awarded December 2024). Across the prime footprint, 35 awards fall under PSC Lease Or Rental Of Equipment–Toiletries, with secondary PSC categories capturing housekeeping, waste treatment, and miscellaneous waste management services. The portfolio spans 18 distinct customer agencies and carries a combined potential value of $3.5 million with 100% of that value obligated.
