Several methods exist to both provide affordable housing and reduce single-occupant vehicle trips. Trip reduction measures can reduce the need for parking, and free up land from surface parking for new development opportunities. That land could be used for both marketrate and affordable housing. Second-car ownership costs about $3, 000 per year. By giving up a second car and using public transportation, a household could save $150 to $250 a month, which could be spenton either rental or owned housing. Local governments could require that parking costs in rental housing be separated from housing costs. This would mean that tenants would save about $40 per month for each car they gave up.
