Architect of the Capitol

What Architect of the Capitol does

The Architect of the Capitol (AOC) is a Legislative Branch agency of the United States federal government, headquartered at the U.S. Capitol in Washington, D.C. Its statutory remit covers the maintenance, operation, development, and preservation of more than 18.4 million square feet of facilities and 570 acres of grounds comprising the U.S. Capitol Building, House and Senate office buildings, Library of Congress facilities (Jefferson, Adams, and Madison Buildings, plus the Packard Campus in Culpeper, Virginia, and the Fort Meade Book Storage Facility in Maryland), the Supreme Court Building, the Thurgood Marshall Federal Judiciary Building, and the U.S. Botanic Garden. The agency is led by an Architect of the Capitol and an Executive Director structure spanning jurisdictions such as Capitol Building, Capitol Grounds and Arboretum, House Office Buildings, Senate Office Buildings, Library Buildings and Grounds, Supreme Court Building and Grounds, and the U.S. Capitol Visitor Center.

The AOC's operational technology is centered on a Building Automation System Network (BASnet) for monitoring and controlling HVAC across the campus, specialized preservation techniques for historic buildings and works of art, climate-controlled modules for Library of Congress collection storage, and a Virtual Desktop Infrastructure based on Omnissa Horizon for telework support. The agency publishes an annual Performance and Accountability Report and maintains an active public-facing communications presence including a website (aoc.gov), a blog (AOC Stories), and accounts on Facebook, X, Flickr, YouTube, Threads, and Instagram.

The business model is congressional appropriations: the AOC does not generate commercial revenue and does not charge for its services. Funding flows from annual appropriations enacted by Congress. Service delivery occurs through internal service request systems, jurisdiction-specific service centers (Capitol, House, Senate, Library Buildings), and the U.S. Capitol Visitor Center, which serves roughly 3-5 million annual visitors through tours and educational programs. The customer base is structurally narrow: U.S. Congress (House and Senate) as the primary client; Library of Congress, U.S. Supreme Court, and the general public as secondary stakeholders receiving facilities management, environmental control for collections, structural preservation, or visitor services respectively.

Broad incumbents

• Library of Congress: Although Library of Congress is a customer of AOC, it is also a comparable federal institution that stewards a 175M-item collection in climate-controlled facilities and operates major preservation programs. It overlaps with AOC in the operational reality of caring for library buildings and collections at scale.
• Supreme Court of the United States: The Supreme Court is a federal institution whose building and grounds are maintained by AOC. As a small federal institution that relies on AOC for facilities services and historic preservation, it shares governance constraints and federal funding dynamics analogous to AOC's institutional context.
• U.S. Department of State (Bureau of Overseas Buildings Operations): The State Department's Bureau of Overseas Buildings Operations plans, builds, and maintains U.S. embassies and diplomatic facilities worldwide. It is comparable to AOC as a federal entity responsible for stewardship of significant government-owned buildings, including historic and high-security properties.

Direct peers

• Smithsonian Institution: Smithsonian is a federally chartered entity that operates and preserves a portfolio of historic museums, galleries, and cultural collections, with comparable emphasis on curatorial expertise, climate-controlled preservation, and large visitor flows. It mirrors AOC's blend of building stewardship and collection care, including management of iconic cultural assets.
• National Park Service: NPS is the federal agency that maintains national historic landmarks, monuments, and cultural landscapes, drawing on a specialized workforce of preservationists and craftspeople. It is comparable to AOC in mission scope (cultural stewardship, grounds management, historic preservation) and in its non-commercial funding model.
• U.S. Botanic Garden: The U.S. Botanic Garden is operated as a jurisdiction within AOC and is responsible for plant conservation and public education. While narrower in scope, it is comparable as a federally operated cultural and educational venue stewarded by AOC.
• U.S. General Services Administration: GSA is the federal agency responsible for managing government real estate and providing workspace, facilities services, and preservation across the U.S. government's civilian real estate portfolio. It is the most direct functional peer to AOC's federal facilities management mandate, though GSA covers the executive and judicial branches rather than the legislative branch.

Regional players

• Houses of Parliament Restoration and Renewal Programme (UK): The UK Parliament's Restoration and Renewal Programme is responsible for preserving the Palace of Westminster, a directly analogous historic seat of national legislature. It is the closest international counterpart in scope and function to AOC's stewardship of the U.S. Capitol, though it operates under different governance.

Emerging players

• Smithsonian National Museum of the American Indian: This Smithsonian museum combines cultural collection stewardship with historic preservation of its facilities, including public engagement and curatorial work. It is comparable to AOC's cultural and visitor-facing operations at a smaller scale and with a thematic rather than government-wide mandate.
• Architectural Heritage Foundation: Architectural Heritage Foundation is a nonprofit that specializes in the restoration and stewardship of historic buildings and cultural landmarks. It is comparable to AOC's preservation tradecraft focus and is a thematic peer in the niche of historic preservation services.
