A Replat is used to remove or reconfigure lot lines within a site to combine into no more than three lots. The boundary of the site must follow existing lot lines. New lot lines cannot be created through this process, but they can be moved. This process is commonly used to reconfigure existing lots to provide new building sites, while retaining existing structures.

A replat can not be used to a create a flag lot or to make a buildable lot from an unbuildable lot remnant or lot of record. Review the related page about Lot Confirmations to determine if your existing lots are considered buildable. 

Steps for review

  1. Submit application Replats are processed through the Type Ix Land Use review process (outlined on the Land Use Review Procedures webpage) . Technical review of the Plat is required and may require revisions.
  2. Submit plat to the County Surveyor It is recommended that the applicant submit the plat to the County Surveyor to be reviewed at the same time as the City. Revisions may be required by the County. Contact Multnomah County for its process and fees at 503-988-3600.
  3. Replat approval Once all City departments are satisfied with the Replat, the applicant must submit plat mylars to be approved and signed by the City. The applicant will be notified via email when the signed mylars are sent to the County Surveyor. The applicant is responsible for obtaining approval signatures from the County Surveyor.
  4. Recording Once the plat has been approved and signed by all required officials in the City and County, the plat must be recorded with the County. The plat must be submitted for recording within 90 days of approval.
