Inclusionary Housing Zoning Code Project

The Inclusionary Housing Zoning Code Project is a collaborative effort between the Bureau of Planning and Sustainability and the Portland Housing Bureau to meet the need for affordable housing in the city. With the adoption of SB 1533 in February 2016, the City of Portland has taken new measures to address the affordable housing shortage and created an Inclusionary Housing Program. The new program mandates the provision of affordable housing units in new multi-dwelling residential development through policies and regulations.

The Zoning Code amendments include:

  • A new chapter in Title 33 (33.245) to require that all development projects with 20 or more dwelling units in one building participate in the Inclusionary Housing Program. The new code sets the percent or share of units in a development that must be affordable at different income levels to meet the terms of the program, called the “inclusion rate”, depending on if the units are provided on-site or off-site.

  • Amendments to base zones and plan districts subject to the Inclusionary Housing Program requirements to create bonuses for floor area and density.

  • Amendments to minimum parking standards for residential development to comply with the Inclusionary Housing Program close to transit and affordable housing units elsewhere in the city.

The other parts of the Inclusionary Housing Program will be implemented through amendments to Title 30, the Housing Code. These provisions include the incentive packages offered to offset the costs to development and a fee schedule for the in-lieu fee option.
