Housing affordability continues to be a major concern for residents across the country. In this report, the authors look at what local governments can do to mitigate rising costs of rental housing in the U.S. The report reviews the root causes of high rent burdens and the consequences, including the impact of housing choice vouchers and modest increases in income. It also discusses why housing costs rise, looking more closely at housing markets and the factors that contribute to rising rent burdens. The report then reviews government policy responses at the local, state, and federal level before laying out a framework that municipalities can use to help provide citizens affordable housing options. It serves as a helpful tool for local officials considering new housing strategies or those interesting in improving existing policies.
