What kinds of tiny houses are permitted in Delaware?

Custom built homes on trailers
If the tiny house is built on a foundation, it’s considered a permanent dwelling. If the home has wheels, it’s considered a THOW (tiny houses on wheels (THOWs)—which comes with additional requirements.

In Kent County and New Castle County, structures under 400 square feet must conform to the
IRC guidelines for tiny houses. To meet the standards set by the IRC, a tiny house must have:
Minimum of 320 square feet of land, if built on a foundation
Minimum of 120 square feet, with at least 70 square feet for non-sleeping areas
Minimum ceiling height of 6 feet 8 inches
Have at least one habitable room with a closet and openable window
You’ll also need to meet the IRC’s requirements for light, ventilation, plumbing, emergency exits, and smoke and carbon monoxide detectors.

If your tiny house is smaller but still road-safe, it is considered a trailer according to Delaware law. The titling fee for trailers is $35 plus a document fee of 4.25% of its value.
Tiny homes on wheels must be inspected and approved before they can be titled at the
Key Takeaway You can build a tiny house on wheels (THOW) or a tiny house on a foundation, but different regulations apply.
Where can I park my tiny house in Delaware?
One of the first questions you need to answer regarding your tiny house is where you will put it. Will you buy property, park it in a friend’s yard, or travel with your new tiny house?
In Delaware, there are no specific laws about where to park a tiny house. You should follow the rules for recreational vehicles. However, bear in mind that different rules apply if you plan to live permanently in your tiny house rather than travel temporarily.
City zoning laws are the best place to start when researching where you can put your tiny house. Bear in mind that the
housing situation in Delaware is rapidly evolving.
At the moment, most counties do not allow for ADUs (accessory dwelling units) in yards. The counties that do allow ADUs have strict limitations. In Sussex County, ADUs may not be full-time dwellings with kitchens. In Kent County, there is a special exception for elderly parents—but the unit must be removed once the parent leaves the property.
How to build a tiny house in Delaware
Ready to build your tiny house? Here are the steps you should follow to stay in compliance with the law and plan the perfect build:
Decide which type of house you want. Will it be a tiny structure in your parents’ backyard, or do you plan to build a THOW for adventuring?
Learn about your local building codes and zoning laws. The best way to find this information is to visit your local library or town hall.
Determine whether you’ll hire a company or DIY.
Civic Works in nearby Baltimore could build your house, or try
Armigers if you need a trailer.
Choose a location for your tiny house. You may decide to relocate to a different city with better zoning—or you may find a friend with a backyard.
Look into insurance for your tiny home. It’s not required by Delaware law, but insurance can help protect the thing you’ve just spent a ton of money building.
If you hire a company to build your tiny house, make sure they are
RVIA-certified. This can help you get the right kind of insurance for your new home.
Be aware that some building projects require preapproval in Delaware. To get preapproval, you may need to pay a fee and submit blueprints drawn by a skilled engineer or architect to the appropriate county office. However, tiny houses are a bit of a gray area.
Remember: You’re not done until your tiny house has been inspected and approved!
