Inclusionary Zoning (IZ) is a local land use planning tool that requires a housing developer under certain circumstances to include a percentage or specified number of affordable housing units within a market-rate development. House Bill 7103, which became law on July 1, 2019, amends the express statutory authorization for mandatory IZ to provide a requirement that developers be kept economically whole in exchange for providing affordable housing. State law now requires local governments to provide incentives to “fully offset all costs” to the developer as a result of an affordable housing requirement.
