Classification of RV/Tiny House/ Office Trailer.

[kb3zvn]

When looking at different installations, does an RV, a Tiny House, and an Office trailer all fall under the RV classifications within the NEC?

I'm looking at an Office trailer to reconfigure into a Mobile workshop/Office/Tiny house style living area and I want to make sure I follow the correct codes during this overhaul.

Thanks in advance!

Charlie.

If you're going to live in it, it probably becomes a dwelling unit ("providing complete and independent
living facilities for one or more persons, including permanent provisions for living, sleeping, cooking, and sanitation.") and also counts as a mobile home. Pay close attention to the definitions of both of them, both in Art. 100 and in Art 550.2 and .4. If you include cooking facilities (stove, 'fridge, etc), you're a dwelling unit.

It could also be rather large RV (Art. 551), but for a recycled office trailer, I think that's a stretch.

Check with the AHJ. Here, I dont think buildings under a certain sized ft² (150 perhaps) are classed as houses.

"Park model" RVs, including tiny houses which are built to fit the park model regulatory scheme, are classified exclusively as RVs and not mobile homes. Office trailers which stay on wheels and can be moved without disassembly (i.e. not like a mobile home, but more like an RV or shipping container) are similar, in that they are not governed as structures. Once you go outside the parameters of an RV then you become subject to all the regulations associated with structures (including mobile homes).
