Landmark Services, Inc.

Landmark Services, Inc., a non-profit AbilityOne organization headquartered in Santa Ana, California, provides custodial, grounds maintenance, landscaping, and facility support services to federal agencies exclusively as a prime contractor, with no subcontracting activity and no participation in federal grants or contract vehicles held by other vendors.

The vendor operates across 14 federal customer agencies, but customer concentration is extreme: GSA Public Buildings Service Region 9 accounts for 53 of 163 prime awards (32.5% of total awards by count) and $76.5 million of the $92.2 million combined potential value (83% of all dollars). Immigration and Customs Enforcement places 15 awards valued at $473 thousand, the Department of Homeland Security US Citizenship and Immigration Services holds 8 awards worth $436 thousand, and the Administrative Office of the U.S. Courts operates 9 awards totaling $52 thousand. The Department of the Navy appears as a customer with 18 awards (magnitude not specified in the source). Landmark's work is geographically concentrated in Southern California federal buildings — the Ronald Reagan Federal Building & U.S. Courthouse and the Santa Ana Federal Building in Santa Ana, and the Chet Holifield Federal Building in Laguna Niguel — where GSA Region 9 maintains two single-award IDCs totaling $18.1 million in combined ceiling value and running through mid-2026.

Landmark's capability footprint is narrow and specialized. The vendor competes almost entirely under NAICS 561720 (Janitorial Services) and PSC 3610 (Housekeeping—Custodial Janitorial), with secondary work in landscaping and grounds maintenance. Representative delivery orders include a $64,761.58 above-standard custodial services order from Immigration and Customs Enforcement at the Santa Ana Federal Building (May 29, 2026), a $3.6 million follow-on year three custodial and grounds order from GSA Region 9 for the Ronald Reagan and Santa Ana Federal Buildings (September 1, 2023), and a $2,760 irrigation repair and valve replacement at the Chet Holifield Federal Building (August 12, 2025). Landmark holds five major parent IDCs with GSA and one Navy contract: GS09P10KSD0166 (19 task orders, $343 thousand), 47PK0220D0011 (18 task orders, $4.2 million), N6871100D7422 (18 task orders, magnitude unstated), GS09P08KSD0076 (17 task orders, $259 thousand), and GS09P15KSD0043 (17 task orders, $200 thousand). The vendor's award trajectory is flat to declining — four awards in 2022, two in 2023, two in 2024, four in 2025, and one in 2026 — with minimal recompete exposure (one award worth $65 thousand completing within the next twenty-four months).

SCI-reported invoiced revenue totals $3.4 million across FY2023–FY2024 ($1.6 million in FY2023, $1.8 million in FY2024) delivered by 16.3 FTEs in FY2023 and 15.5 FTEs in FY2024. These figures are a partial federal services subset; SCI excludes goods, micro-purchases, and non-federal revenue and captures only contracts above the $150,000 reporting threshold. Landmark's government-paid hourly-rate posture on SCI-reportable prime contracts runs a median of $51.40/hr, with rates at the 10th percentile around $48.70/hr and 90th percentile at $54.10/hr. The vendor performs with no subcontractor engagement across SCI-reportable work.
