The Enterprise Green Affordable Housing Policy Toolkit offers a roadmap for state and local governments working on green affordable housing initiatives. The toolkit describes methods to promote green affordable housing, processes for adopting new policies, and detailed guidance on implementation. The toolkit’s case studies identify innovative policy from Denver, Washington, D.C., Iowa, Minnesota and Washington State. Each jurisdiction profiled has forged a unique but replicable path toward equitable and sustainable development. We recommend using this toolkit as a resource to strengthen green affordable housing policy in your community.
