Is it a mobile home or manufactured home, does it really make a difference?

Yes, the names, or labels, and commonly used terms amongst Manufactured Home or Mobile Home, RV (Recreational Vehicle) may vary depending on the jurisdiction.  Smaller homes also referred to as a Park Model or Park Trailer are actually classified as an RV. 
Modular Buildings are factory-built housing which does not include a Manufactured House.  Modular structures are permitted and inspected as would a site-built residence.

Be careful before you buy as there are different permitting requirements depending the zoning where you intend to place a home, some may have more restrictions, some may not be allowed.  Learn how to identify one and know the difference.  Make sure that your home will meet the Land Use Requirements with the Planning Division and all of your permits are issued before placement of your home.  Failure to do so could result in a code enforcement violation. 

What is the difference between a Manufactured Home and Mobile Home?
  • Manufactured Home is a single-family dwelling built according to the Department of Housing and Urban Development (HUD) Manufactured Home Construction and Safety Standards Act, which is a national, preemptive building code. 
  • Mobile Home is a factory-built dwelling built prior to June 15, 1976 to standards other than the HUD Code, that were acceptable under applicable state codes in effect at the time of construction or introduction of the home into the state. WAC 296-150M.  A mobile home (also know as a pre-HUD home) will need to obtain a fire safety certificate from the Washington State Department of Labor and Industries  (any subsequent move will require a separate fire safety certificate.)
Issuance of a permit for placement of the manufactured home, it is only for the manufactured home itself.  Separate permits are required for the following but not limited to:   
  • Landings over 30" from finished grade to top of the deck.   
  • Porch/patio (any roof cover)    
  • Any additions or alteration.
  • How do I know if the manufactured home has been altered?  Should I get an HRI "homeowner requested inspection" before purchasing?

Additions must be freestanding from the manufactured home.  Additions that are attached to the home or any alteration to the home will require approval from Washington State Department of Labor and Industries.
