Section 455.405 - Recreational vehicle conversion to structure(1) A recreational vehicle that has a title issued by the Department of Transportation does not qualify as a structure. If a recreational vehicle is being converted to use as a structure, at the time of commencing the conversion the owner shall surrender the title and any registration issued for the recreational vehicle to the department for cancellation. A recreational vehicle that is converted to use as a structure is subject to the state building code.(2) There is a rebuttable presumption that a recreational vehicle has been converted to use as a structure if the recreational vehicle is located outside of a mobile home park as defined in ORS 446.003 and:(a) Has been rendered structurally immobile; or(b) Has direct attachment to utilities.455.405 was added to and made a part of ORS chapter 455 by legislative action but was not added to any smaller series therein.
