If you’d like to build your dream tiny house on a trailer, there’s quite a few things to consider!





How long do you want the trailer to be? Remember, most trailers have a hitch that adds 4ft on to the total length of the trailer. Sizes: 16ft, 18ft, 20ft, 24ft, 28ft

Also, if the trailer beams are too broad they can frost in cold climate, making your floors chilly, and affecting the “dew point”.



How wide do you want the house to be? Tiny houses on trailers can be up to 8’6” before you need a wide load permit. A wide load permit isn’t too expensive and is obtained from the DMV.

If you don’t plan on traveling with your TH much, consider that it can be up to 10ft or even 12ft wide.

This includes all appliances, windows, and furniture. Also have a master plan about what personal belongings you’re keeping, so when you design you know where you’re going to keep your limited stuff.
