Expanding Housing Choice in Clackamas County

HB 2001 Implementation Project 

Expanding housing choice in Clackamas County means providing more housing types and options for residents. Housing in Clackamas County is becoming less affordable, and House Bill 2001 (HB 2001) , approved by the state legislature in 2019, will allow property owners to build up the supply of housing- resulting in a wider range of housing types that can improve housing affordability in urban, unincorporated Clackamas County.

What is House Bill 2001 (HB 2001) and why was it passed?

In June 2019, the State of Oregon passed a law (House Bill 2001) to expand housing options and opportunities for Oregon residents. 

This law requires cities and counties to allow “middle housing” in urban residential zones that already allow houses. The purpose of the state law and the HB 2001 Implementation Project is to increase the amount of lower-cost market-rate housing.  Since middle housing -- townhouses, duplexes, fourplexes, etc. -- can be less expensive to build than conventional single-family houses and new apartment complexes, that may make it possible to charge lower rents or sale prices. Also, middle housing will be allowed in more locations than apartment complexes are allowed today, which may result in more new housing units being developed.

State law requires that the County amend the Clackamas County Zoning and Development Ordinance (ZDO), and if necessary also the Comprehensive Plan, by June 30, 2022, to allow for the development of middle housing in urban unincorporated, residential zones.

What is “Middle Housing” and what types of housing does it include?

Middle housing includes accessory dwelling units (ADUs), duplexes, triplexes, quadplexes (also known as fourplexes), townhouses, and cottage clusters (several small houses centered on a common area such as a lawn or courtyard).

Clackamas County already allows ADUs per state law. (ADUs are a secondary house or apartment unit that is on the same lot as a larger, primary house.)


Why is HB 2001 Important? And where does it apply?

Housing in Clackamas County is becoming less affordable.

That makes it hard for many residents to pay for other basic needs like food, health care, and transportation. This is why steps are being taken so that more residents in Clackamas County can live in housing they can afford. HB 2001 encourages more housing types within residentially zoned areas to improve housing affordability in urban, unincorporated Clackamas County. It does not eliminate the option to build single-family homes.

The changes that will allow for more housing choice will only apply in urban, unincorporated Clackamas County where infrastructure—including water, sewer, storm drainage and transportation facilities—is adequate to serve additional housing.
