Washington Mobile Home Market Data: Census Counts, Owners and Renters

How many mobile homes are in Washington

The U.S. Census Bureau's American Community Survey counts about 183,749 mobile homes in Washington (margin of error ±3,218), which is 5.6% of all housing units in the state. That ranks Washington 15th of the 50 states by number of mobile homes, and it is 2.3% of the roughly 8,095,000 mobile homes in the 50 states.

This count covers every mobile home in the state, whether it sits in a park, on the owner's own land or on family land. It is not a count of parks or lots.

Owners and renters

Of the occupied mobile homes in Washington, about 127,156 are lived in by their owners and about 37,206 are rented. The remaining 19,387 or so are vacant, including seasonal homes.

In a mobile home park, an owner-occupied home is the classic lot-rent tenancy: the resident owns the home and rents the land under it. Rented homes include park-owned homes leased together with the lot.

Why this page has no park count or average lot rent

No federal survey publishes the number of mobile home parks, the number of lots or the average lot rent by state. Earlier versions of this page showed estimates for those figures. We removed them because they could not be traced to a published source.

To price lot rent in Washington, survey the parks that compete with yours in the same submarket, and check the rent-control guide for any limit on increases.
