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 on each lot or parcel zoned for residential use that allows for the development of 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, quadplexes, 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.
Planning Assistance to Local Governments
House Bill 2001 provides $3.5 million to DLCD for planning 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.
Projects are currently underway for jurisdictions that were approved for funding. Assistance will run through June 30, 2021, the deadline for Medium cities middle housing regulations to be updated. Visit the
Grant Opportunities page for more information.

DLCD is currently in 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.

On July 23, 2020 the Oregon Land Conservation and Development Commission (LCDC) adopted a model housing code and administrative rules (OAR 660-046) to guide the development of duplexes in medium-sized cities as part of House Bill 2001. Additionally, on
August 5, 2020 LCDC adopted administrative rules to allow cities affected by House Bill 2001 to
apply for an Infrastructure-Based Time Extension to delay enactment of middle
housing requirements in areas with deficient water, sewer, storm drainage, or
transportation facilities. Administrative rules and the Medium Cities Model Code may be accessed at the Secretary of State webpage.
Stay Connected – Provide Comments
Rules for House Bills 2001 and 2003 are currently in development. The
Land Conservation and Development Commission will hold public hearings where members of the public may submit public comments. For administrative rules applicable to large and Metro cities, the first hearing will occur on September 24-25. Public comment will be held open until November 12-13, when LCDC is anticipated to adopt administrative rules. Public comments may be submitted in-person at these meetings or emailed to DLCD at
