This is an update concerning a recently passed City Council resolution and subsequently approved
ordinances regarding Accessory Dwelling Units (ADU). The ordinances have temporarily suspended
System Development Charges (SDC) for new ADUs. The goal of this action is to create incentives for
the development of ADUs.
The initial resolution directed all affected bureaus (Water, Parks and Recreation, Environmental Services
and Transportation) to implement the resolution by April 15, 2010. Please note that the Bureau of
Development Services is responsible for the development review process, but does not assess a SDC. All
other non-SDC development related fees are due at time of permit issuance. Questions about SDC’s
should be directed to the individual Bureaus (Water, Parks and Recreation, Environmental Services, and
Accessory Dwelling Units (ADU) are defined by the Portland Zoning code as a second dwelling unit
created on a lot with a house, attached house or manufactured home. The second unit is created auxiliary
to, and is smaller than, the house, attached house (rowhouse) or manufactured house.
Here is a link to the resolution:
