How to Register a Tiny House on Wheels (THOW) in the United States
Tiny houses on wheels (THOWs) are becoming very popular in the United States. They give you freedom, flexibility, and a simple way of living. But before you hit the road, you must register your tiny house legally. Registration rules may differ from one state to another, but the process usually follows the same basic steps. Let’s go through them one by one in detail.
1. Know What a THOW Is
A Tiny House on Wheels is a small home built on a trailer. It can move from one place to another, like an RV (recreational vehicle). Most states classify THOWs as recreational vehicles or travel trailers. Knowing this helps you understand what kind of registration you need.
2. Check Your State’s Rules
Each state in the US has its own rules for tiny houses. Some treat THOWs like RVs, while others treat them like regular trailers.
Before you start, visit your state’s Department of Motor Vehicles (DMV) website. Search for “trailer registration” or “RV registration.” This will show you what forms and documents you need.
3. Make Sure Your Trailer Is Certified
The trailer under your tiny house must be certified. Most states require it to have a Vehicle Identification Number (VIN).
If your trailer is store-bought, it should already have a VIN.
If you built it yourself, you can apply for a new VIN through your DMV.
Without a VIN, you can’t register your THOW.
4. Get a Weight Certificate
The DMV often asks for your trailer’s weight certificate. You can get this by taking your tiny house to a public or certified scale station.
The weight helps the state decide what type of license plate your THOW needs.
5. Gather Important Documents
You will need:
Bill of sale (proof that you own the trailer or house)
Manufacturer’s Certificate of Origin (MCO) (if bought new)
VIN verification form
Proof of insurance
Weight certificate
Make sure all documents match your name and address.
6. Visit Your Local DMV
Once you have everything ready, go to your local DMV office. Tell them you want to register your Tiny House on Wheels.
You will fill out a few forms and pay a small registration fee. The DMV might inspect your THOW to confirm that it meets safety standards.
7. Get Your License Plate
After approval, you will receive your license plate and registration papers. Attach the plate to the back of your THOW, just like a regular vehicle. This makes it legal to drive on public roads.
8. Consider Insurance and Taxes
Some states require insurance for your THOW before registration. Others don’t, but it’s always a good idea to have it for protection.
Also, remember that you may have to pay annual registration fees or taxes depending on where you live.
9. Check Zoning and Parking Rules
Registering your THOW allows you to move it legally, but parking it is another story.
Each city or county has zoning laws that decide where you can live in your tiny house. Some RV parks or private lands allow THOWs, while others don’t. Always check the local rules before parking your home long-term.
10. Keep Your Documents Safe
Once your THOW is registered, keep copies of your registration, insurance, and title in a safe place. You might need them if you’re stopped by police or if you sell your tiny home later.
Final Thoughts
Registering a Tiny House on Wheels may sound complicated, but it’s actually simple when you follow the right steps.
Start with your DMV, collect all the needed documents, get your VIN, and pay the fees. Once done, your THOW will be legal, safe, and ready for the road.
Living tiny is about freedom — and registering your THOW gives you that freedom legally.
