Inclusionary Zoning

In a Nutshell

Inclusionary Zoning (IZ) is a tool that requires or encourages developers to make a percentage of housing units in new residential developments available to low-and moderate-income households. In return, developers receive incentives or development rights in the form of density bonuses, zoning variances and/or permits that decrease construction costs. IZ broadens the supply of affordable housing and encourages mixed-income communities.

Practical Solution

The “How To”The “How To”

PolicyLink is a leading advocate for inclusionary zoning. See Policylink's Development Toolkit on Inclusionary Zoning (IZ).

IZ are either “mandatory” or “voluntary” in their requirements.

Mandatory- requires developers to build affordable units in exchange for various incentives, which can include development rights or density bonuses. This method, although met with some resistance from developers, has produced more affordable units than the alternative.

Voluntary- allows developers the opportunity to “opt-in” in exchange for incentives.

Planning & ZoningPlanning & Zoning

The American Planning Association produced this model inclusionary zoning ordinance. The ordinance includes the following sections:

- Definitions
- Procedures for review of affordable housing developments
- A requirement that the developer enter into agreements to ensure that they are building affordable housing units
- Designate an officer or review panel to review affordable housing development plans
- Enforcement provisions

 Minneapolis is an example of a city that has implemented inclusionary zoning requirements.
