All subdivision and condominium plats must have a name reserved prior to submitting to our office for review. To reserve a name, please submit a name reservation request using the form below.

Proposed plat names may not be spelled the same nor sound similar to names of existing plats within Multnomah County. See our Plat Naming Policy for additional requirements. You may use our SAIL website for a preliminary check of the availability of the plat name by entering the first few letters of the proposed name using the “Subdivision Plat by Name” or “Condo Plat by Name” search options found under the “Surveys” menu item at the top left of the page.

If you have questions or need assistance, please email us at

If the name you enter has already been requested, the form will reject your entry. Please try a different name.
Please give full name of person reserving plat name.
