Making Housing More Affordable: Smart Strategies for Cities and Communities

Housing affordability is a growing challenge across the U.S., but it’s not unsolvable. Cities, states, and developers have a wide range of tools to reduce costs, expand supply, and improve access—especially for low- and middle-income households. Here’s a breakdown of the most effective strategies:

🧱 Expand Housing Supply Through Zoning Reform

  • Legalize multi-family housing in areas zoned only for single-family homes
  • Allow accessory dwelling units (ADUs) like basement apartments or garage conversions
  • Reduce minimum lot sizes and density restrictions to enable more efficient land use
  • Permit mixed-use development to combine housing with retail and services

📍 Example: Minneapolis eliminated single-family zoning citywide, opening the door to more duplexes and triplexes

🚧 Streamline Development and Lower Construction Costs

  • Eliminate or reduce parking minimums, which can add $50,000+ per unit
  • Accelerate permitting and approvals for projects that meet zoning rules
  • Encourage modular and prefab construction to reduce labor and material costs
  • Use public land for housing, leasing or donating underutilized parcels

📍 Washington, D.C. used Metro-owned land to facilitate the development of 1,000 new housing units near transit hubs

🏘️ Innovate With Ownership and Community Models

  • Encourage shared equity models where residents build wealth over time
  • Promote live-in flips and house hacking to reduce individual housing costs
  • Engage large employers and developers to invest in housing near job centers

📍 Microsoft launched a $500 million initiative to address workforce housing shortages near its headquarters

🧭 Policy Shifts That Make a Big Difference

  • Reduce regulatory barriers that slow or block new housing
  • Align transit and housing planning to reduce transportation costs for low-income families
  • Reform inclusionary zoning to avoid unintended supply constraints
