WA State Licensing: Manfactured home/travel trailer sub-agency

Manufactured home/travel trailer sub-agency

A manufactured home/travel trailer sub-agency endorsement is required for each additional business location after the first, primary manufactured home/travel trailer business has been endorsed.

Business site requirements

Your business site must:

  • Comply with all applicable building codes, zoning, and other land-use ordinances. For more information, please contact your city or county directly.
  • Be located at a commercial property with an enclosed building.
  • Have a permanent sign with the business name and the type of business (such as Auto Sales).
  • Have an operating telecommunications system and a phone number listed in directory assistance.
  • Be open from 10 a.m. – 4 p.m., five days per week. These hours are referred to as “normal business hours.” Additional hours and days of operation may be added at your discretion. You must prominently post the hours of operation at the main entrance doors.
  • Have an area to maintain books, records, and files at the business site. If two or more vehicle dealer businesses share a location, all records, office facilities, and inventory must be physically separated and clearly identified.


To get a Manufactured home/travel trailer sub-agency endorsement, you must have the following:

  1. $30,000 bond. Bonds are available through many insurance companies. We recommend you research the cost of your bond before you apply for a license.
  2. Copy of your property tax statement, or the rental/lease agreement for the business site, as proof of ownership. The rental/lease agreement must be valid for at least one year.


All retail vehicle dealers are required to use the E–Permitting system. Find out more about E–Permitting.
