What is the role of housing affordability within urban land-use planning?

• A. It governs only retail space planning.
• B. It is unrelated to transportation access.
• C. It governs only the construction cost of single-family homes.
• D. It affects access to jobs and services; planning tools include inclusionary zoning, density bonuses, subsidies, and transit-oriented development to provide affordable units and reduce displacement.

Answer: (D)

Housing affordability in urban land-use planning is about ensuring that people can access housing that fits their incomes and that costs of housing plus transportation don’t push too many residents out of opportunities. When housing is affordable relative to wages, more people can reach jobs, schools, and essential services without long, costly commutes, which supports a more inclusive economy and reduces displacement. Planners address affordability with tools like inclusionary zoning (requiring affordable units in new developments), density bonuses (allowing more units if some are affordable), subsidies to fund or preserve affordable housing, and transit-oriented development that concentrates housing near transit to lower transportation costs and improve access to employment. These approaches help balance housing supply with demand, promote equitable access, and support sustainable growth. The other options misstate the role by limiting affordability to retail planning, claiming no link to transportation, or focusing only on construction costs for single-family homes.
