EGG In 2019, the Oregon state legislature passed House Bill (HB) 2001. The bill stipulated that all sin-
gle-family residential zones must allow "middle housing" -including duplexes, triplexes, quad-
plexes, townhouses, and cottage clusters-in order to address three goals:
Options Supply Diversity
Provide more housing Increase the overall supply Encourage more inclusive
options to meet the needs of housing units. neighborhoods by allowing
of different households. more affordable housing

The resulting middle housing structures are usually similar in size to a conventional single-family
dwelling, though middle housing dwelling units themselves are typically smaller. The dwellings
may be rented or owner-occupied, or a combination of both. The dwellings may be rented or own-
er-occupied. They may be attached or detached.
While the bill was intended to allow middle housing in areas where it wasn't previously allowed, it
did not prohibit the development of detached single-family homes.
Lake Oswego's Response to HB 2001
In June 2022, the City Council adopted amendments to the Community Development Code in order
to comply with the minimum requirements of HB 2001 while also maintaining consistency with
the community's sense of place, neighborhood character, and livability. Similar to a single-family
dwelling, no land use approval will be required for middle housing; only a building permit is re-
quired for middle housing that meets all applicable zone standards.
Though more housing types are now permitted within all residential zones, the overall scale or
mass of middle housing buildings will still be subject to the same zoning requirements as detached
single-family housing. These standards include maximum height, minimum setbacks, maximum
lot coverage, and other similar regulations that establish the maximum bulk or "building envelope"
permitted on a site.
The graphic below illustrates how the City's existing dimensional standards would be applied to a
single-family dwelling, as compared to various middle housing types:

Covenants, Conditions, and Restrictions (CC&Rs)
Any existing private agreements, deeds, or covenants, codes, or restrictions (CC&Rs) that restrict
the development of middle housing adopted prior to HB 2001 will remain effective. However, HB
2001 prohibits Homeowners Associations (HOAs) from adopting new provisions that prohibit mid-
dle housing development on or after January 1, 2020.
