House Bill 2001 Background
In 2019, the Oregon state legislature passed House Bill 2001 (“HB 2001”). The law required cities to allow a wider variety of housing choices in all residential zones in order to address three goals: options, supply, and diversity.
House Bill 2001 required the City of Lake Oswego to amend our Community Development Code for compliance by a deadline of June 30, 2022. Staff released a public review draft of the proposed code amendments for consideration at a Planning Commission Public Hearing on April 11, 2022. A City Council Public Hearing was held on May 17, 2022, and code amendments to comply with the requirements of the bill were adopted by the Council on June 7, 2022.
State Goals & Concepts:
- Options: Provide more housing options to meet needs of different households.
- Supply: Increase overall housing supply.
- Diversity: Encourage more inclusive neighborhoods by allowing more affordable housing types in more areas.
Types of Middle Housing
The bill stipulates that all single-family residential zones must allow “middle housing”, which includes duplexes, triplexes, quadplexes, townhouses, and cottage cluster housing.
- Duplex: 2 attached dwelling units on one lot
-
Triplex: 3 attached dwelling units on one lot
-
Quadplex: 4 attached dwelling units on one lot
-
Townhouse: Between 2 and 4 attached dwelling units, each on their own lot
-
Cottage Clusters: A grouping of five to eight small houses oriented around a common greenspace or courtyard.
