Who Decides What Gets Built in DC, and Who Pays for It?

Washington, DC, looks the way it does because of decisions spread across federal agencies, review panels, Congress and the courts. Much of the land in the city’s monumental core belongs to the federal government, so changing it is a national question as well as a local one. Two projects pushed by President Donald Trump, a ballroom on the site of the White House’s former East Wing and a triumphal arch at the Virginia end of Arlington Memorial Bridge, have turned this little-known system into front-page news.

Who Owns and Runs the Landmarks

Different landmarks have different managers. The National Park Service, part of the Interior Department, runs the National Mall, most of the major memorials and President’s Park, which includes the White House grounds. The General Services Administration manages most federal office buildings, the Architect of the Capitol cares for the Capitol complex, and the Smithsonian Institution runs its museums with a mix of federal and private money. Each of these bodies falls under the jurisdiction of congressional committees that oversee its work and set its budget.

Who Reviews New Projects

A major federal project in the capital usually passes through at least one review commission. The National Capital Planning Commission, created in 1924, has approval power over federal projects in the region. Its members include presidential appointees, DC appointees, federal agency heads and congressional committee chairs, and the president names its chair. The Commission of Fine Arts, created in 1910, is an advisory panel of presidential appointees that comments on design. Projects may also need an environmental assessment under federal environmental law and a review of their effects on historic sites, and a 1910 law limits building heights.

New memorials follow a separate law. The Commemorative Works Act of 1986 divides the area around the National Mall into zones. Under that law, a commemorative work placed in the central zone, known as Area I, needs an act of Congress approving its location. That rule reflects the separation of powers: the Constitution gives Congress power over federal property, while the executive branch manages it day to day.

Who Pays

Congress funds the agencies that run these sites through annual appropriations. New memorials, however, are usually built with private money raised by a sponsoring group, and agencies also accept gifts through nonprofit partners. The Park Service has rules for these philanthropic partnerships meant to stop a donor from gaining influence over government decisions.

The White House Ballroom

The White House announced a privately funded ballroom in July 2025, and crews began demolition of the East Wing that October, before either commission had reviewed the plans. The administration argued that review was required only for new above-ground construction. Donations flow through the Trust for the National Mall, a nonprofit partner of the Park Service. A funding agreement released after a public-records lawsuit showed that the Trust collects a 2.5 percent fee on the roughly $400 million project and that donors can request anonymity.

The Commission of Fine Arts, whose members Trump had replaced in October 2025, approved the design in February 2026. The planning commission, then chaired by a senior White House aide, voted 8 to 1 to approve it on April 2, 2026, with two members voting present. Days earlier, U.S. District Judge Richard Leon had issued a preliminary injunction, finding that the National Trust for Historic Preservation was likely to win its argument that the ballroom needs congressional authorization. A divided federal appeals court upheld his order in August. The Supreme Court then granted a stay in a 5 to 4 vote on August 31, finding that the Trust likely lacks standing to sue, without deciding whether the project is legal. Leon’s order never took effect, and construction has continued while the case goes on.

Money has also become a question for Congress. In May 2026, Senate Republicans proposed $1 billion for Secret Service security work, and the agency said $220 million of it would go to hardening the ballroom site. Supporters said a secure event space protects the president, while critics, including some Republicans, objected to taxpayers paying for part of a project promised as privately funded. Reports in late May said Senate Republicans were expected to drop the provision, and this article could not confirm whether any of that money was later approved.

The Triumphal Arch

Trump first showed models of an arch in October 2025 to mark the nation’s 250th anniversary. The site, Memorial Circle on Columbia Island, is Park Service land on the ceremonial route between the Lincoln Memorial and Arlington National Cemetery. The Commission of Fine Arts approved the design concept in May 2026, and on November 5 the planning commission gave the 250-foot arch final approval by an 8 to 4 vote.

The legal fight centers on authority. The administration says a 1925 law tied to Arlington Memorial Bridge already authorized a monument at the circle, so no new vote by Congress is needed. Veterans, the District of Columbia, Virginia and Arlington County have sued, arguing that the site falls under the Commemorative Works Act or that environmental review was inadequate. Within an hour of the vote, U.S. District Judge Tanya Chutkan issued a 14-day temporary restraining order, writing that the government’s reading of the old law shows “how far defendants must stretch” to justify the project.

Critics also say the arch would interrupt the vista across the Potomac that was designed to symbolize national reunion after the Civil War. Funding is less clear than for the ballroom. This article could not locate a published cost estimate from the White House, and officials have described a mix of public and private money. CBS News reported that the National Endowment for the Humanities reserved $2 million, plus up to $13 million to match private gifts, for the arch.

The Debate

Supporters of the administration’s approach argue that presidents have reshaped the White House many times, that a large and secure event space is overdue, and that both review commissions approved the projects. They note that President Joe Biden also removed members of both commissions in 2021, so replacing appointees has precedent. Some also say the arch completes a plan from the 1920s that was never finished.

Critics argue that the process ran backward, with demolition before review, and that commissions led by the president’s own aides cannot act as independent checks. They say anonymous donations to a president’s project create conflict-of-interest risks, and that only Congress can authorize permanent changes of this size on public land. Beneath these disputes is a broader question: when a president wants to change the shared symbols of the capital, how much say should Congress, local governments, the courts and the public have?
