Manufactured Home

If they are willing to rebuild it to meet IBC requirements with an engineer, not a problem...

Otherwise, no.

I have never been asked for that specific type of conversion.
 
Maybe. Got one sorta on the back burner in my neck of the boonies. No application yet, but client in a situation where the thing can't be easily made habitable.. but the bones are OK.
 
Happens all the time in rural areas. Doesn't make it right or legal. What does zoning have to say about it?
State law may have something to say if it is used in conjunction with a commercial use.
 
Are all manufactured homes mobile homes? What about modulars?

I found the definition in the ICC IRC to be less than clear, and the Commentary didn't help any.

Here is a summary of the differences between mobile homes, manufactured homes, and modular homes:

Mobile Homes

  • Built before June 15, 1976
  • Also known as trailer homes or manufactured homes
  • Constructed on a steel chassis with wheels, allowing for easy relocation
  • Typically smaller in size, with a maximum width of 8 feet 6 inches and a maximum length of 40 feet
  • Not designed to be permanently attached to a foundation
  • Often associated with temporary or transitional housing
Manufactured Homes

  • Built after June 15, 1976
  • Constructed on a permanent chassis, but not designed to be relocated
  • Can be built on a variety of foundations, including a permanent foundation, pier and beam, or a crawl space
  • Can range in size from small to large, with no maximum width or length limits
  • Held to federal building codes set by the Department of Housing and Urban Development (HUD)
  • Often referred to as “mobile homes” by some manufacturers, but this term is no longer officially used
Modular Homes

  • Built in a factory, but designed to be permanently attached to a foundation
  • Constructed on a permanent foundation, similar to traditional site-built homes
  • Held to local and state building codes, rather than federal codes
  • Can range in size from small to large, with no maximum width or length limits
  • Often difficult to distinguish from traditional site-built homes
  • Can be customized to meet local building codes and design preferences
Key differences between manufactured and modular homes:

  • Manufactured homes are built to federal codes and are designed to be moved, while modular homes are built to local and state codes and are designed to be permanent.
  • Manufactured homes are typically smaller and more affordable, while modular homes can be larger and more customized.
  • Manufactured homes are often associated with temporary or transitional housing, while modular homes are designed to be permanent residences.
It’s worth noting that the terms “mobile home” and “manufactured home” are often used interchangeably, but technically, “mobile home” refers to homes built before 1976, while “manufactured home” refers to homes built after 1976.

What's the source of these definitions? It's not the IBC or IRC. The ICC definition could apply to either a "trailer" home or a modular.

Not really...

MANUFACTURED HOME.

For mobile homes built prior to June 15, 1976, a label certifying compliance with the Standard for Mobile Homes, NFPA 501, ANSI 119.1, in effect at the time of manufacture, is required. For the purpose of these provisions, a mobile home shall be considered to be a manufactured home.

A "modular" gets fully field inspected, manufactured does not....
