Garden Cottages Add Residential Capacity in Portland

To facilitate increased residential density within the city limits of Portland, Oregon, home owners can add "detached accessory structures" to their residential lots under a housing ordinance provision for ‘co-housing.’

One example, the Garden Cottages at Ruth’s House are two tiny homes adjacent to a larger dwelling. The bathroom uses a combo sink and toilet fixture to save space and water. A large deck acts to expand the living space to the outdoors.

Eli Spevak of Orange Splot Cohousing Development of Portland, constructed the two "detached accessory structures" on a single-family residential lot next to a existing home. The cottages were part of the 2009 Build it Green! home tour.
