House Bill 2001 aims to provide Oregonians with more housing choices, especially housing choices more people can afford. The law, passed by the 2019 Oregon Legislature, lets people build certain traditional housing types, like duplexes, in residential zones. These housing types already exist in most cities, but were outlawed for decades in many neighborhoods. These limitations contribute to increased housing costs and fewer choices. House Bill 2001 will require updates to local laws that currently limit the types of housing people can build.
More Diverse, Affordable Choices
People need a variety of housing choices. Today, too many Oregonians are paying too much for the housing they have, and are limited to renting or buying detached single-unit homes. Also, the composition of Oregon households is shifting; more than a quarter of households today are a single person living alone.
At different times in our lives, we have different needs. Think about where a young adult might want or be able to afford to live, or imagine the needs of a retired person. These laws may help older adults remain in their neighborhoods and be near grandchildren, friends, and caregivers.
Traditional Housing Types Allowed in Most Neighborhoods
Most cities in Oregon already allow duplexes in certain circumstances. But House Bill 2001 requires Oregon's medium-sized cities to allow duplexes in all areas zoned for single-family homes by June 30, 2021.
Additionally, by June 30, 2022, Oregon's large cities (with population over 25,000) and cities in the Portland Metro region, must allow duplexes, triplexes, fourplexes, cottage clusters, and townhouses in residential areas. These housing types can be more affordable and meet the housing needs of many younger people, older people, and people who work hard but can’t afford a large, detached house of their own.
Cities Can Set Siting and Design Requirements
Cities will continue to be able to set reasonable siting and design requirements on all houses built in residential zones. They are also able to make sure that new housing is built with adequate infrastructure such as water, sewer, and roads. Cities are required to provide supporting infrastructure and the law directs DLCD to help cities figure out their infrastructure gaps.
Transition Likely Gradual
While the law allows more housing types, DLCD expects the transformation of housing choices to be gradual. Cities have allowed some of these housing types in certain areas for decades. Not many have been built. Local knowledge of how to build these housing types will grow over time. The building of them will depend on local housing markets, likely led by small-scale, local builders and contractors.
Technical Assistance to Local Governments
House Bill 2001 provides $3.5 million to DLCD for technical assistance to local governments to:
- Help local governments with the development of regulations to allow duplexes and other housing specified in the bill.
- Help local governments with the development of plans to improve water, sewer, storm drainage and transportation services in areas where duplexes and other traditional housing would not be feasible due to service constraints.
Technical assistance is expected to be provided from mid-2020 to June 30, 2021, the deadline for local laws to be updated.
DLCD will conduct rulemaking to provide a model code local governments can use to meet the requirements of House Bill 2001, and a process and criteria for the evaluation of local infrastructure plans under HB 2001.
