AN INTRODUCTION TO INCLUSIONARY ZONING
What is an Inclusionary Zoning (IZ) policy?*
- IZ policies are local rules that require or encourage for-profit housing developers to include (and pay for) some affordable housing as part of new housing projects.
- The affordable units are either built by the for-profit developer within the “market rate” development or elsewhere, or built by non-profit developers on land donated by the for-profit developer, or with the help of a cash in lieu payment by the for-profit developer.
What does an IZ policy do?
- Inclusionary policies make sure that housing for all income groups is produced when new housing is being built.
- They let for-profit developers know what their affordable housing obligations will be before they begin to plan their projects.
How do IZ policies work?
- Inclusionary policies can be in a local ordinance, part of a General or Comprehensive Plan policy, specific zoning requirements, or special permit approvals for housing projects.
- Inclusionary policies usually define:
- The income levels for which the affordable housing will be built.
- What percentage of each project will be affordable.
- How long the affordable units will remain affordable.
- Incentives for developers to comply with policy.
How does an Inclusionary Zoning policy start?
- Community groups begin by identifying what they want IZ to accomplish - what incomes to assist, whether affordable units being part of market rate projects is a priority and so on.
- Key stakeholders and allies should be consulted early on to win their support. These could include housing advocacy groups, labor unions, churches, and friendly elected officials.
- The IZ ordinance or policy is often written with help from technical experts and then is either introduced through the appropriate local law-making body (usually a City Council) or is put on the ballot to be voted on locally.
- Advocates should expect opposition from for-profit housing developers and their elected allies, as well as some homeowners who may not want affordable housing residents in their neighborhoods.
Where are Inclusionary Zoning policies most effective?
- IZ policies can be effective in any growing community.
- In communities that have a strong housing market, developable land, and a public infrastructure to support large, new developments.
- When a local housing market starts to improve, but BEFORE it gets really strong, so it is in place during a boom.
How do IZ policies provide community benefits?
- Inclusionary housing polices create affordable housing and diverse, integrated communities.
- They do not directly address the other priority benefits.
How does IZ further equity principles?
- Development without displacement. Investment without disenfranchisement. Inclusionary policies allow development to occur while creating housing for low-income people.
- City & public assets are the people’s assets. Residents have a right to the City. Inclusionary policies help residents of all economic levels benefits from the use of public resources to support development.
- Equitable distribution of burdens, benefits and decision-making power. Inclusionary policies help create a more equitable distribution of burdens and benefits. They can indirectly impact equitable decision-making as residents organize to win the policy.
- Housing is a human right. Inclusionary policies help make this fundamental belief a reality
- Long-term community vision and stewardship of community assets. Long-term affordability an important part of Inclusionary policies but the issue of who serves as the community’s stewards is not addressed by these policies.
What are the main Criticisms/Challenges of Inclusionary Zoning?
- Challenges for inclusionary policy efforts include deciding on the policy focus, building a strong coalition and being prepared to respond to opposition arguments.
- Private developers often claim it is not their role to address a social concern and that inclusionary requirements make a project financially infeasible.
- Local officials and policy makers worry that IZ will slow down development and “scare away” developers, even though this has not been the case.
- Some homeowners or local residents with misconceptions about “poor people” may oppose IZ because they do not want lower-income housing in their area. This opposition can be mitigated through community education and constituency building activities.
Where are IZ policies being used?
- Inclusionary polices began as a tool to promote economic integration in the suburbs. They have been used in every imaginable kind of community in every part of the country to promote housing for all.
- Inclusionary policies are the norm in many parts of the country. They can be found in many local jurisdictions, large and small including: San Francisco, Denver, Montgomery, MD, Santa Fe NM, Chapel Hill, NC, Burlington, VT, New York, Chicago, and Baltimore, MD.
