The YIMBY (Yes In My Backyard) movement makes a valid point: excessive regulation has constrained housing supply and driven up prices. This is a diagnosis that many conservatives share. Where the disagreement lies is in the proposed solutions and the assumption that supply alone will solve the crisis.

The supply argument has merit. Research from the National Association of Realtors estimates that the U.S. faces a housing shortage of approximately 5.5 million units. Restrictive zoning — single-family mandates, minimum lot sizes, parking requirements — has limited construction in high-demand areas. A 2020 study from the Mercatus Center found that land-use regulations add an average of 20-30% to housing costs in major metro areas. Conservatives should support reducing genuinely excessive regulation that prevents voluntary market transactions.

However, the "just build" framing oversimplifies in several important ways. First, new market-rate construction primarily serves higher-income buyers and renters. The filtering effect — where older housing becomes affordable as new supply absorbs demand — operates over decades, not years. In the short and medium term, building luxury apartments in a gentrifying neighborhood does not help low-income residents.

Second, the push to eliminate local zoning control raises legitimate federalism concerns. When Congress or state legislatures override local zoning decisions, they remove the ability of communities to shape their own character and manage growth. Local governance is a conservative principle. Residents who bought homes with the understanding that their neighborhood would remain residential have legitimate property rights concerns when the rules are changed to allow high-density development next door.

Third, infrastructure constraints are real. Housing doesn't exist in isolation — it requires roads, water, sewer, schools, and transit capacity. Building without adequate infrastructure creates congestion, overcrowding, and declining quality of life. California's water constraints, for example, pose genuine limits on how much development the state can sustain.

The conservative approach should be: reduce genuinely burdensome regulations that prevent reasonable development, streamline permitting processes that add years and millions to construction costs, maintain local control over land use decisions while encouraging voluntary upzoning, and ensure that infrastructure investment keeps pace with growth. More housing is part of the answer — but local governance, property rights, and infrastructure reality must be part of the equation too.
