Code requirements are summarized in this brochure and can be found in Section 5.5 of the Springfield Development Code.
On March 5, 2018, the City Council adopted Ordinance 6376 to amend the Development Code to make it easier to build ADUs within the City. The amendments went into effect on April 4, 2018.
On June 25, 2018, the City Council adopted Ordinance 6384 to allow ADUs in the urbanizable fringe (the area within the urban growth boundary that is outside the City limits). There were also some minor amendments affecting the setback from an alley when converting a garage to an ADU, requiring that unpaved off-street parking spaces be rocked and maintained, and always requiring a foundation for manufactured homes and towable structures.
