Under certain circumstances the City of Portland allows for the subdivision of lots where underlying lots of record (or supplemental lot lines) occur. The locations of these supplemental lot lines are available for areas immediately surrounding individual addresses via PortlandMaps. This map shows the locations of these lot lines for the entire neighborhood. Lots may only be split if a property owner owns more than 50% of the area of the underlying lot and if the new lot meets the minimum lot size in the zone (3,000 sq ft in the R5 zone). Additional restrictions may apply. Distribution of Supplemental Lot-Lines Eastmoreland
The Covenant provides permanent and irrevocable protection for your property as described in the Covenant allowing for lot line adjustments that may expand or reduce the overall size as long as additional “legal” lots (for additional residences) are not created.
