Revised draft of the Residential Infill Project ready for review

Project staff to brief the Planning and Sustainability Commission on Revised Proposed Draft on February 12; vote to recommend to City Council in March.

Over the past few months, the Residential Infill Project team has been revising the Proposed Draft to reflect the Planning and Sustainability Commission’s (PSC) possible amendments and preparing materials to answer questions about how the proposed new rules will affect Portland's single-dwelling neighborhoods:

  • What is the economic feasibility of the proposal?
  • How much more housing will be created under these new rules?
  • What will these units cost?
  • Who will benefit?
  • What will be the effect of these proposals on vulnerable populations?
  • Will more or fewer households be displaced?

Now the highlights of the Revised Proposed Draft will be presented to the PSC on Tuesday, February 12, starting around 2 p.m. You can watch the briefing live on the Bureau of Planning and Sustainability YouTube channel.


After hearing public testimony on the initial proposals to "right size" the scale of new development and increase housing options in single-dwelling zones, commissioners requested changes to:

  • Increase additional housing options to include up to four units (fourplexes) on both corner and non-corner lots.
  • Allow additional housing options in all R2.5, R5 and R7 (single-dwelling) zones except:

• Areas with flood or landslide hazards or significant natural resources. These areas, designated by a new “z” Constrained Sites overlay zone, will retain existing regulations for corner duplexes or one accessory dwelling unit with a house.
• Lots that do not meet minimum lot sizes for three or four units (R2.5 = 3,200 sq ft; R5 = 4,500 sq ft; R7 = 5,000 sq ft)
• Infrastructure constraints, including lack of paved streets, sewer or water service.

  • Increase the allowed size (FAR) for duplexes and triplexes (no increase for a fourplex). Examples on an R5 (5,000 sq ft lot):

• 2,500 sq ft – one house (same as Proposed Draft)
• 3,000 sq ft – one building with two units
• 3,500 sq ft – one building with three or four units

  • Provide a bonus FAR for keeping an existing house or for providing one affordable unit at 80 percent MFI.
  • Allow historically narrow lots in R5 to be built with a pair of attached houses.
  • Eliminate minimum parking requirements.  


The following Revised Proposed Draft reports have been posted on the project website.

Appendices that have not been revised can be found here.

Explore the Map App. Parcel-specific information is available through an updated Map App that reflects the revised mapping proposals.


  • Tuesday, February 12 – Briefing: Revised Proposed Draft (RIP is on agenda from 2 to 4 p.m.).Staff will walk the Commission through their revised proposals to see how their tentative amendments work together as a package.
  • Tuesday, February 26 and Tuesday, March 12: Work Sessions and Possible Vote

(Please confirm the date and time on the agenda one week prior by visiting the PSC calendar)


The PSC’s possible amendments took into consideration the public testimony they received last spring on the Proposed Draft of the Residential Infill Project. They are anticipating making their recommendations to the City Council in March. The public will be able to provide testimony on these recommendations to City Council as part of their review — anticipated in summer 2019.
