Insights from Urban Institute outline three key principles for shaping a national housing affordability strategy aimed at addressing the growing gap between housing costs and what households can afford. The approach emphasizes increasing overall housing supply, particularly in high-demand areas, while also ensuring that new development includes options accessible to low- and moderate-income households.

The framework highlights the importance of preserving existing affordable housing alongside building new units, noting that maintaining current inventory is often more cost-effective than replacement. It also underscores the need for targeted support for renters and homeowners, including subsidies and policy tools that help stabilize housing costs and prevent displacement in vulnerable communities.

These principles reflect a coordinated, long-term strategy that balances supply, preservation, and affordability supports. The recommendations point to the need for collaboration across federal, state, and local levels to create sustainable housing solutions that promote stability, economic mobility, and broader access to safe, affordable homes.
