Property owners assigning a name to subdivided property must reserve a name for the property with the Auditor's Office. State law (RCW 65.04.050) requires this so no two subdivisions have the same or similar name.
Our office must approve the subdivision name even if the city or county has approved the name, since subdivisions may not have the same name within a county, not just a single city or town. You can check on the availability of the name you want by visiting our Public Record Index Online to see if any maps have been recorded using your desired name.
To reserve a map name, fill out the Plat Name Reservation Form (PDF/Word). Return the completed form by fax, 360.786.5223, or mail or deliver it to:
Thurston County Auditor
Attn: Plat Name Reservation
2000 Lakeridge Dr. SW
Olympia, WA 98502
After you submit the form, our office will evaluate the name. Once we approve your name, our office will issue a Plat Name Reservation Certificate. The certificate is valid for one year from the approval date and you must include it with the map when submitting for recording. Please allow two weeks for the approval process. If your project extends beyond the expiration date, please renew your name to get a new certificate. If we don't approve your name, we will contact you with an explanation and to go over your options.
