Portland's New Housing Stock is Leaning Towards ADUs
Permit numbers for Accessory Dwelling Units have closed in on those for single-family homes
Newly released data shows the city issued 615 building permits for new accessory dwelling units or ADUs in 2016, approaching the 867 permits issued for regular houses.
Data from the Bureau of Planning and Sustainability and Bureau of Development Services shows ADUs are growing in popularity each year, while the number of new single-family houses seems to have plateaued. The housing and affordability crisis and growing traffic congestion are driving up the popularity of ADUs, especially in Portland's close-in neighborhoods. ADUs provide desirable separate living spaces for family or private rentals to supplement homeowners' incomes.
