This report describes practical ways to increase the supply of affordable-accessible housing, which refers to lower priced homes located in areas where automobile travel is not required to access basic services and activities. This typically consists of lower-priced apartments, townhouses, duplexes, small-lot single-family and accessory suites located in urban neighborhoods where shops, schools, healthcare and jobs are easy to reach by walking, bicycling and public transit. This helps achieve numerous economic, social and environmental objectives. Demand for affordable-accessible housing is growing. Some current policies discourage such development, leading to a shortage in many communities, particularly in growing cities. More than two dozen policy and planning reforms described in this report can increase affordable-accessible housing development.
