County Of Sonoma

County of Sonoma, doing business as County Administrator's Office, is a U.S. local government entity that operates as a federal grant recipient across housing, transit, social services, public safety, and community development programs—receiving formula allocations and project grants from HUD, the Federal Transit Administration, the Department of Health and Human Services, and the Department of Justice rather than competing for federal contracts.

The county operates as a prime grant recipient in 130 of 175 awards (74%) and as a sub-recipient in 45 awards (26%), with no federal prime contracting footprint. Its federal customer base reflects its role as a county administrative and pass-through entity. The Department of Housing and Urban Development's Assistant Secretary for Community Planning and Development leads by award count with 50 grants, followed by the Federal Transit Administration with 30 awards and the Administration for Children and Families with 14 awards. These three agencies account for approximately 66% of all recent federal awards. The Department of Justice Federal Bureau of Investigation Headquarters Division and the Department of Agriculture Forest Service R5-Pacific Southwest Region round out the top funders by potential value.

County of Sonoma's grant portfolio centers on affordable housing, homelessness prevention, and emergency shelter operations funded under HUD formula programs. Recent major recipients include the Emergency Solutions Grant (CFDA 14.231) awarded February 5, 2026, for $145,708 through February 4, 2028, supporting street outreach, emergency shelter operations, and rapid re-housing services in Larkfield-Wikiup, California, and the HOME Investment Partnerships Program (CFDA 14.239) awarded the same date for $660,599, extending through September 30, 2034, to fund rehabilitation and acquisition of affordable rental housing and homebuyer assistance. The county also received Community Development Block Grant allocations (CFDA 14.227) on October 1, 2024, through September 1, 2031, for community development activities benefiting low- and moderate-income residents. Federal Transit Administration Section 5307 and Section 5339 grants support Sonoma County Transit's fixed-route operations, preventive maintenance, and vehicle replacement for the Santa Rosa and Petaluma Urbanized Areas; a $6.4 million American Rescue Plan Section 5307 award from May 9, 2022, funded operating assistance during COVID-19 recovery.

County of Sonoma also administers federal social services as a sub-recipient pass-through entity, receiving allocations from California's Department of Social Services for CalFresh Employment and Training, foster care assistance, Temporary Assistance for Needy Families (TANF), and child welfare support. The California Department of Public Health sub-awards funds for the California Home Visiting Program and maternal and child health initiatives. The Office of Emergency Services passes through victim services funding under the Office for Victims of Crime program and state Homeland Security Strategy implementation grants.

Activity increased to 28 awards in 2024 from 8 in 2022, with five awards facing completion within the next twenty-four months. The combined potential value of recent awards stands at $63 thousand reported in the vehicle data, though obligated amounts across all awards total $294.2 million, reflecting the large scale of HUD formula allocations and FTA transit funding. County of Sonoma's corporate structure includes the Sonoma County Community Development Commission as a subsidiary, which operates as a housing authority and community development corporation. The county's federal footprint is characteristic of large urban counties operating as formula-grant recipients and state pass-through entities, with no prime contracting activity and limited exposure to competitive federal procurement vehicles.
