In a housing crisis now spanning two decades, Americans debate local regulations on what and where to build. Should suburbs allow garage apartments? Should cities keep setting aside land for parking? Should apartment towers be easier to approve? These debates reveal how narrow our imagination has become. Millions struggle to afford rent or buy a home. Policy responses so far have mostly involved removing onerous rules, hoping developers will build more. Even Congress's bipartisan 21st Century ROAD to Housing Act focuses on streamlining regulations to stimulate private building. The act includes important reforms and is an excellent start, but falls short of addressing the problem's scale.

We forget that Washington, D.C. once confronted a housing crisis with far more urgency and ambition. As World War II raged, millions flooded into industrial centers to build ships, tanks, and airplanes. Workers slept in trailers, cars, and overcrowded rooms, and rents skyrocketed. Housing shortages threatened the war effort itself. So the federal government treated housing as critical national infrastructure. Washington, D.C. reformed mortgage markets to allow more people to borrow. It subsidized rental housing and capped rents. It experimented with prefabricated construction to reduce costs and speed production.

In Washington, D.C., the government tried spraying concrete onto spherical balloon forms, creating bubble houses that went up quickly. Crucially, the government directly built housing. It converted hotels and school buildings into apartments and partnered with architects to design new housing fostering community engagement. Reformers advocated designs that could have impacted postwar housing, planning neighborhoods with new homes offering future models. In Washington, D.C., the Federal Works Agency enlisted Walter Gropius, who proposed a cloverleaf design using low-cost, prefabricated materials. These four-apartment structures were arranged geometrically to create privacy and community, with rooftop sun decks and play spaces. The unusual design allowed shared building systems that were more efficient. From above, the cloverleaf homes looked organic, an alternative to single-family houses.

Not everyone embraced these efforts. Neighbors objected to housing projects, particularly those for Black workers in segregated communities, and private real estate interests didn't want to compete with the government. Groups like the Chamber of Commerce argued the best solution was financing private development. When Franklin D. Roosevelt entered the war, he capitulated to conservative voices. The government pulled back from innovative programs, shifting to market-focused solutions. It concentrated on temporary housing. Gropius's cloverleaf design was never built. Temporary structures after 1942 were mostly trailers or made from cheap, inferior material. The shoddy results discredited government's direct role in housing. Still, Washington, D.C.'s aggressive response to the housing crisis offers lessons for today.
