A Problem Decades in the Making
The United States faces a housing shortage of approximately 4 million units, according to estimates from the National Association of Realtors. This deficit has pushed home prices and rents to levels that are unaffordable for a growing share of the population. Nearly half of all renters now spend more than 30 percent of their income on housing, the threshold that the federal government defines as cost-burdened.
The crisis is driven by decades of underbuilding, restrictive zoning regulations, rising construction costs, and NIMBYism that has blocked new development in many high-demand markets. Solving it will require action at every level of government, along with innovation from the private sector.
Zoning Reform Gains Momentum
Several states have enacted sweeping zoning reforms that allow higher-density housing in areas previously reserved for single-family homes. Oregon, California, and Minnesota have passed legislation eliminating or reducing single-family zoning restrictions statewide. Early data from these reforms shows modest but meaningful increases in housing production, particularly of accessory dwelling units and small multifamily buildings.
Modular and Manufactured Housing
Factory-built housing, including modular construction and modern manufactured homes, offers the potential to reduce construction costs by 20 to 30 percent while dramatically accelerating timelines. Companies like Factory OS, Volumetric Building Companies, and others are demonstrating that factory-built units can match or exceed the quality of site-built construction.
Regulatory barriers remain significant. Many municipalities maintain outdated building codes and zoning restrictions that effectively prohibit manufactured housing in desirable locations. Federal and state efforts to modernize these regulations are underway but progress has been slow.
Community Land Trusts Scale Up
Community land trusts, which separate ownership of land from ownership of buildings to keep housing permanently affordable, have expanded significantly in recent years. More than 300 community land trusts now operate across the United States, managing portfolios that range from a handful of homes to several thousand units.
The model works by having the trust retain ownership of the land while selling or renting the buildings at below-market rates. When a homeowner sells, they receive a limited equity return while the trust ensures the unit remains affordable for the next buyer.
Employer-Assisted Housing Programs
Major employers in high-cost markets are investing directly in housing for their workforces. Programs range from down payment assistance and forgivable loans to direct development of workforce housing near employment centers. Companies including Kaiser Permanente, Google, and several hospital systems have committed hundreds of millions of dollars to housing initiatives in their communities.
Adaptive Reuse of Commercial Buildings
Converting obsolete office buildings, hotels, and retail properties to residential use offers another pathway to increasing housing supply. While not every building is a suitable candidate, successful conversions can add housing in established neighborhoods with existing infrastructure, transit access, and amenities. Cities that have streamlined permitting and offered tax incentives for conversions are seeing the most activity.
