Inclusionary Zoning (IZ) is a program put in place to produce affordable inclusionary units for households making 80% or less of the area median income (AMI). An inclusionary unit is a dwelling unit set aside for sale or rental to a targeted household as required by Subtitle C, Chapter 10.

The purposes of the Inclusionary Zoning (IZ) Program are:

  • To further the Housing Element of the Comprehensive Plan by increasing the amount and expanding the geographic distribution of adequate, affordable housing available to current and future residents;
  • To utilize the skills and abilities of private developers to produce quality affordable housing;
  • To leverage private development, combined where appropriate with zoning density increases, to produce affordable housing throughout the District;
  • To mitigate the impact of market-rate residential development on the availability and cost of housing available and affordable to low- and moderate-income households;
  • To increase the production of affordable housing units throughout the District to meet existing and anticipated housing and employment needs;
  • To provide for a full range of housing choices throughout the District for households of all incomes, sizes, and age ranges to preserve diversity and to ensure the benefits of economic integration for the residents of the District;
  • To stabilize the overall burden of housing costs on low- and moderate-income households;
  • To create a stock of housing that will be affordable to low- and moderate-income residents over a long term; and
  • To make homeownership opportunities available to low- and moderate-income residents.
