The End of Portland Single Family Zoning

portland real estate zoning changes

In late June, 2019, the Oregon State Legislature passed a bill that requires cities to allow homeowners and real estate developers to add housing units where the demand is highest. How does this affect the zoning changes already developed by Portland’s Residential Infill project? And how will it affect the look and feel of Portland neighborhoods?

Our podcast episode below goes over the number of showings it takes to sell a home in our area and also takes on the end of single family zoning in Portland.

HB 2001 and Portland Real Estate

The new bill, HB 2001, requires Oregon cities of more than 10,000 to allow “missing middle” housing types to be built in all residential zones. In other words, it eliminates single-family-only housing zones, mandating that cities permit duplexes, triplexes, fourplexes and additional accessory dwelling units to also be built in these zones. 

This new law affects Portland as well as many cities in the wider metro area, including Gresham, Hillsboro, Beaverton, Aloha, Tigard and Lake Oswego. The cities have two years to implement the new zoning rules. 

According to The Oregonian/OregonLive, the bill had bipartisan support, and the concept, known as “upzoning”, has been written into law in other major cities like Minneapolis and Seattle. Oregon is the only state in the nation to make upzoning a requirement in all its cities. 

But what about Portland’s Residential Infill Project?

The Portland Department of Planning and Sustainability has been working on the city’s Residential Infill Project, or RIP, for a number of years. After many public comment periods, RIP is expected to receive final approval by Portland City Council this fall. Read our detailed blog post about this plan, and its effect on Portland real estate here.  

The Project proposes to change the following aspects of zoning in Portland:

  • In single-family housing zones, the range of permissible housing types will be expanded to include duplexes, triplexes, fourplexes and additional accessory dwelling units.
  • It will also expand the area where these housing types will be allowed (but excludes them from being built in areas where there is a landslide risk, flood risk or potential natural resource conflict).
  • Building size limits will be allowed to increase incrementally with the second or third unit. For instance, on a 5,000 square-foot, R5-zoned lot, a house could be up to 2,500 square feet, a duplex 3,000 square feet, and a triplex or fourplex tops out at 3,500 square feet.

As currently written, RIP meets most of the requirements of HB 2001. In other words, Portland was ahead of the curve in developing this infill plan. And though Oregon made history by upzoning all its cities in one fell swoop, Portland is a step ahead on implementation — and many consider that a good thing, not just for those who want to invest in property in Portland, but for those who actually want to live here, too. 

The Real Estate Anti-Infill Argument

Of course, RIP has met with its share of opposition in Portland. Single-family neighborhood homeowners don’t want to see big changes in the numbers of households on their streets. They’re worried that a lot of new “plexes” and ADUs will be built suddenly, eating up their on-street parking and destroying the quiet character of the neighborhood. Renters also worry about RIP, because although the rule changes will create more housing in the long term, they will be displaced when the homes they’re renting are in the process of being redeveloped. With Portland’s contractor shortage, it could take some time for new units to actually come on the market.

In fact, time is the critical element here that should ease homeowners’ and renters’ worries. Zoning rules might change with a simple pound of the gavel at a city council meeting, but new construction doesn’t happen overnight. There are no immediate financial incentives for property owners to redevelop — yes, they can rent more units, but the typical homeowner isn’t interested in that. Single-family homes currently being rented might be good candidates for splitting into two or three units, but that’s a big investment for property owners in a rental and Portland real estate market that has actually cooled in the last couple of years. See our 2020 Portland real estate forecast here.

The Residential Infill Project is, in fact, as small step toward catching up with Portland’s housing shortage, but it’s not a total solution. Housing advocates are still asking for more (more affordable) apartment buildings, and Portland is still trying to figure out how to add the thousands of homes that are needed for its growing population, without changing the character of the city.

A Portland Real Estate Case Study

For further evidence that upzoning — described in some news articles as a “ban on single-family neighborhoods” — is actually slow to change neighborhood character, we can look to a Portland neighborhood that made a very similar change to its zoning rules 40 years ago. Michael Andersen is a researcher for for Sightline Institute and happens to live in the Northeast Portland neighborhood that legalized the “missing middle” of housing back in 1980. Unlike other single-family neighborhoods at the time, Andersen’s pocket neighborhood allowed property owners to develop, for a fee, duplexes, triplexes, fourplexes and ADUs. 

In a home of about 200 low-density residential buildings, Andersen writes, 20 have been built using the 1980 upzoning rules. “For those keeping score,” he adds, “this means that every four years, our little pocket where fourplexes are legal has changed by an average of 1 percent.”

Portland Real Estate Opportunities

For those looking to buy or sell a home in the Portland real estate market — or now, thanks to HB 2001, in any city in the metro area — the new infill rules provide some new opportunities. Making the mortgage payment could be a lot easier by renting out an accessory dwelling unit or the other side of your duplex. Finding a home to purchase may ultimately become slightly easier as well. Time will tell.
