Mobile Homes

Mobile homes are titled as vehicles and the titling options vary depending on the circumstance.  Mobile homes can be titled and taxed as personal property.  Mobile homes can also be affixed to the land and taxed as real property.

The process of titling a mobile home can be complicated.  The transaction is completed in the Treasurer and Auditor offices.  Depending on the transaction, customers may also need to visit one of the following offices:  Assessor, Planning department, local title company, Labor & Industries, or Department of Revenue.  

  1. Title Transfers and Original Purchases
  2. Title Eliminations
  3. Removal from Real Property
  4. Moving or Destroying Mobile Home

Selling or Purchasing a Mobile Home

First, a tax record must be established or updated at the Treasurer’s office.

Second, the mobile home title transaction is processed at the Auditor’s office Licensing division. Note: Licensing subagents cannot title mobile homes. 

The Assessor’s office updates the property record ownership after the mobile home transaction is completed.

Some transaction types require additional paperwork including inheritance, divorce, changing your name, putting your home into a trust, lienholder out of business, ownership in doubt, or you can't find the title. Contact our offices to review the requirements. Common title transactions are outlined below:

Transferring Ownership (New owner, adding or removing an existing owner)

The first step in transferring an existing mobile home is to contact the Treasurer’s office. There you will complete the required tax clearance form. The Treasurer's office will collect any excise tax or fees due and approve the tax clearance form

The second step is to contact the Auditor's office Licensing division to transfer the ownership record with the Department of Licensing (DOL). All new registered owners must be present with photo ID or have their signature notarized on a Vehicle Title Application.

  • Documents required can vary but typically include the signed Certificate of Ownership (title) or notarized Affidavit of Loss/Release of Interest, Bill of Sale, and the tax clearance form from the Treasurer's office. If the mobile home is older than 1976, the sellers must also complete a Mobile Home Notice Affidavit.
  • Once the paperwork is processed, the Assessor's office is notified to update the property record ownership.

Ownership changes are complete once the record is updated in all three offices: Treasurer, Auditor, Assessor. 

Brand New Mobile Home

The dealership where you purchased the mobile home will often title the mobile home for you. You may wish to ask the dealer if this is the case in your situation. If the dealership gives you the Manufacturer’s Statement of Origin/Certificate of Origin (MSO/MCO), it is up to you to title the mobile home. 

The first step is to go to the Treasurer’s office with the purchase documents. After presenting the MSO/MCO, complete any required tax clearance forms and pay any applicable taxes and fees. 

The second step is to go to the Auditor's office Licensing division to create an ownership record with DOL. Documents required can vary but typically include the MSO/MCO, the dealer invoice, and the tax clearance form from the Treasurer's office. All registered owners must be present with photo ID or have their signature notarized on a Vehicle Title Application. The fee payable to DOL depends on your transaction and tax due. Once the paperwork is processed, the Assessor's office is notified to update the the property record ownership.

Ownership records are complete once the record is created in all three offices: Treasurer, Auditor, Assessor.
