Soon, four new homes will join the existing single-family residence at 8404 NE Holladay Street in a cottage cluster configuration. This multi-structure project represents one of the first cottage cluster developments in Montavilla and adds housing inventory while retaining the 1931-era home. This new form of permissible development became legal in July 2022 as part of the Residential Infill Project 2 (RIP2) after City Council adopted the zoning code changes in June.
Portland’s embrace of cottage cluster lot configurations stems from a 2019 update to Oregon State law. The Housing Choices bill describes cottage clusters as “groupings of no fewer than four detached housing units per acre with a footprint of less than 900 square feet each and that include a common courtyard.” Each residence is detached from the other units making them distinct from row-house developments or other middle housing options. This building arrangement permits irregularly shaped lots and forgoes spacious private yards for larger common open areas shared by the clustered homes. It is permissible for the structures to share one property, or they can each reside on small individual lots, as they will in this NE Holladay Street development.
The new two-story homes proposed for this property will surround the existing house, with half the units addressed on NE 84th Avenue and the others fronted on NE Holladay Street. Demolition crews will likely remove the detached garage to the south of the home. However, the new property owners have yet to file for that permit. All work applications are currently under review, with construction likely months away. When completed, this project will become an example of the newest housing infill method in Portland and could represent a trend in density development.
