As tiny houses on trailers increase in popularity, so does the demand for insider tips on how to build them. Since you’ll be towing your entire home behind you, we can assume that you’ll want to do it as safely and securely as possible. When building the structure of your tiny home, it’s important to understand the planning process–including your options should you get stuck. Without further ado, here is everything you need to know about building a tiny house on a trailer.

Things To Know Before Starting:

  • Gross weight: This refers to the total amount of weight of your trailer, tiny house, and belongings–it’s important not to forget to factor in the weight of the stuff you own! Read more here to learn about weight restrictions for a tiny house on wheels.
  • Legal lengths: Although most tiny house trailers don’t need to be much longer than 28 feet, the legal limit for trailers can’t exceed 53 feet (far bigger than most tinys!) Keep in mind that you need to factor in the length of the trailer tongue into your total.
  • Vehicle for towing: A necessary and often overlooked step in the towing process, is owning the right kind of vehicle for towing a heavier load. While the trailer needs to be able to support your tiny house, your vehicle needs to have a capacity to support both!
  • Approximate cost: The cost of building your tiny house on a trailer depends on many factors. For example, a tiny home that has electricity professionally installed will you cost more than if you know how to do it yourself.

Pro Tip: Don’t forget; it’s okay to consult a professional if you don’t feel comfortable with an aspect of the build. It’s always better to be safe than sorry!

The Best Trailer Options

While there are many different trailer options out there, the best one for a tiny house would be a flatbed trailer. This is because you get the type of surface area that’s appropriate for the size of a tiny house. Here are some of the most popular models of flatbed trailers:

Just as the name implies, this type of trailer has an elongated arm that reaches over to the ball hitch on your towing vehicle. In order for this type of trailer to work, you’ll need to own a truck.

This trailer has a small ramp-like section in the rear that angles towards the ground. While it makes loading easier, (think trailer used to haul cars) it can also be quite tricky to build a tiny house on a surface that’s not perfectly flat. Most likely, you’ll need to do some custom modifications to the dovetail before proceeding with the build.

Bumper Pull

These trailers connect to the vehicles trailer hitch which is located somewhere near the bumper. The deck is nice and flat between the wheels, making it the perfect platform for building a tiny home. It’s important to note that a bumper pull trailer that is attached directly to a hitch on the bumper will not be strong enough to support the weight of a tiny house.

Unlike the bumper pull trailer, this option raises the deck over the wheels. This particular feature may allow for a slightly wider, flatter surface; but it will also require you to be more cautious in regards to height. The last thing you want is to scrape off your tiny house roof in a tunnel!

Steps to build your own tiny house on a trailer

1. Make a list

Write down everything you want to include in your tiny house. It’s a good idea to start thinking of the ways different features can be combined to create functional spaces. For example, a window seat can be used as a dining room seat or even storage space!

2. Brainstorm

Draw a diagram of all the different spaces to get your creative juices flowing. This will help you to visualize where each house function is in relationship to others. For instance, it will allow you to see if the bathroom is close enough to the sleeping space. If you have a computer, you can use a graphics program to draw each part of the house into moveable parts.

3. Design Structure

  • With your plan in hand, you can now look into the structural aspects. If you’re concerned about a lack of knowledge or experience, you can consider the following options:
  • Head to the bookstore or browse the internet for helpful resources.
  • Ask the tiny house community some questions! The majority of people involved in tiny houses are extremely supportive and willing to share some advice with tiny house hopefuls!
  • Contract a tiny house builder to help with the job. If you’re really unsure about your build skills, this might be a good option for you. Be sure to have clear communication with your builder about what you do and don’t want!

Plumbing and electricity

Although nice to have, there isn’t a rule that says you must have either. If you do choose to have electricity, you have the option of using alternative energy solutions like solar energy. That way, you can more easily take your tiny home off-grid with fewer restrictions on where your tiny house can go. While you don’t need to have plumbing, you might find it easier to hook up your tiny house for it just in case. Luckily for you, the cost of utilities is far less than in a residential home. It takes less energy to heat or cool a tiny house!

Tiny House Tips

  • Depending on your budget, purchasing home insurance could be a great idea. Look at it as protecting your investment.
  • Consider buying a tiny house shell: The best of both worlds! This could save you from making structural errors that could potentially make you start from square one. You can also decorate the interior at whatever pace you wish because your tiny home is protected from the elements.
  • If you’re planning on moving your tiny home often, don’t forget to factor fuel in as a monthly expense.
  • Take your time planning! You want to plan and build your tiny home so it’s both comfortable and safe.

While there are quite a few steps involved in building your own tiny house on a trailer–the results can be truly fantastic if done right. Remember, you have the option of buying a tiny house shell if you’re unsure about the structural aspect! It’s important to do extra research or seek assistance if you think you’re not doing something correctly.

After all, quality over quantity is a big part of what tiny living is about!
